    Has anyone has any electrical problems with their R350? I have the Saks Fifth Avenue edition and the tail gate motor burned out last week and now the battery light and brake light have come on. The service department said they do not know what the problem is and want to drive it for a while. I traded my ML for this beautiful car last November because of a lot of problems with it. I don't think the dealership is particularly excited to see us again.

    My tailgate had to be reprogrammed. Works ok now. I have only about 2K miles. No other notable electrical issues other than sensitive anti-pinch mechanisims in the rear quarter windows during the winter.

    I believe there are one or more service bulletins out on the tail gate issue, so you are not alone. I am 10,000 miles in and no real issues.
  • benzsterbenzster Member Posts: 152
    No problems with mine either.
    I have seen a vehicle with this issue. The bullitin states adjust latch/ do not replace. We tried to adjust 4 times and ended up installing a new latch to remedy........

    I do have problems with the rear left taillight. The bulb burnt out prematurely with dark metal vapor on the inside of the bulb. So, I tested the power supply with the good bulb from the right. The bulb did not light up (although I have noticed before I found the browned out bulb that the light would either be dark or slowly come on with a dull glow from time to time when I was following the R350). Took it to the dealer and they said it was a bad bulb and replaced it. Several months afterwards the same thing happened with no light from that rear red light. Something weird that I also noticed was the yellow light at the left coming on sporadically. Took it to the dealer and they had to order a new socket (?) WHICH IS ON BACK-ORDER!!! It has been over a month and they still don't have it. I think it is risky to drive the car with a bad red taillight, not to mention risk of getting a ticket? Does anyone know of such issues with the light? What action can or should I take?

    YES!
    We had a dvd player that crapped out and the battery keeps draining. The dealer has had the car for over a week and they have no idea why this is happening.
    And come to think of it, the hatch doesn't always close properly.

    We bought our brand new 2008 R350 this month. 2 days after driving away, the battery drained completely (car would not even open with key). The technician chalked it up to one of two things: 1.) the kids leaving a light on, even though our kids can't reach the upper light & do not touch anything else. (we are especially careful to check for lights on at night, especially because of kids/school etc). or 2.) the battery was not charged fully at delivery, due vehicle sitting in dealer lot for winter months (we are in New England). This morning i had 2 super important appts & a game w/ the kids, The car battery is dead again. The vehicle has 428 miles on it! It died at 205 & now 400+ miles. I purchased it with 170 miles on it brand new.. what is going on with Mercedes?

    I love the way the car drives, and kids love the space, but i gave up my old Merc wagon for the R350 not just because the kids love it.. but becasue of R-E-L-I-A-B-I-L-I-T-Y. I can't explain this so far & when the technician came prompty this morning (same person as first time), he couldn't either. Told me definitely there was something unnecessarily draining the battery and this was/is very odd.. i have to take it in for service now for them to diagnose The car is 12 days old!. Do i have a lemon? (gosh hope not because i love the interior, the drive etc), but this is unacceptable.. Will see what the dealer says & does..
  • lcjdlcjd Member Posts: 2
    We are having the same problem. We bought our 2008 R350 in Dec07 with 5700 miles. At 9700 miles, the battery was completely drained and the car was towed to the dealer. They had it for 9 days, then returned it (with hesitancy) saying they still didn't know what caused it and it would probably happen again. They did replace the battery. Well, it did happen again at 13,500 miles, it was towed back to the dealer and they kept the car for 2 days. They wanted to keep it longer, but we said we needed it back. Now, at 14K, it was towed back to the dealer for the 3rd time with a completely drained battery. They called today to say MB told them to replace a control unit(?) and the part would be in in 2 days. We also have some problems with the clocks in the car. They don't keep accurate time a few days before the car battery is drained.

    Like you, we love the car. It drives great, has so much space and the kids love having their friends ride with them. I don't see us keeping it once the warrenty expires unless this problem is diagnosed!

    Have a 2006 R-350 with about 13500 miles. Car won't start, changed battery all the lights cut on but the car still won't start. Jump it off and finally Now a red battery light cut on saying I need to take my car to the dealership. My car is in the garage now tomorrow I have to call Mercedes and waist another day of electrical problems. This is a 2006 why won't my car start. I check my car remote batteries, replaced them. Still won't start. I should have waited and bought the 2006 GMC Acadia. Has anyone have anything happen like this let me know. I might just trade it in on the GMC. Never had a problem with a gmc never and i still have one gmc Denila
  • hockeyhopeshockeyhopes Member Posts: 2
    Well, i have a bit of good news to report. About 3+ weeks ago the dealership got tired of servicing our car (read my previous message on this forum). Also the lemon law kicked in as it had been there for 14 days. The service dept could not figure out how a new car with 450 odd miles on it was being drained/ would not start after a full charge evry couple days. Told me car has 3+ miles of wiring & rather than tinker with it, they replaced our 'old' R350 with a brand new one with 9 miles on it. Exact same with identical package & they threw in the Xenon lighting as a courtesy for all the trouble. They will be sending the old one back to Mercedes in Alabama to lok at. Been driving our new car close to a month now & it is a dream.. the reason we bought this yacht in the first place. Well, that's our story so far. I hope Benz can resolve the wiring/battery issues in future models to alleviate trouble some of us have been experiencing. All the best.

    Congrats on the replacement!! :)
  • soundermnsoundermn Member Posts: 2
    We've got 18k miles on the car. Lease is up next month and it's going back. Electrical problems we've had:
    - electric tailgate fail, adjusted twice.
    - rear windows stopped working.
    - SRS red warning light. Dealer replaced airbag module. Light is on again, six months later
    - battery light comes on periodically. Dealer has fixed it three times, and its on again now
    - low antifreeze light comes on periodically. Dealer has fixed it twice, it's fine now.
    - installed tow package, and it took the dealer 7.5 hours to connect the harness. After discount, it cost me $500 to install the wiring harness (which is the same as ML harness)
    - non-xenon headlights. Had to return to dealer twice to adjust headlight aim

    All these are minor problems, and were fixed without question, and without drama at the dealer. However, for a car that cost $60,000 with tax, I should not have to take it back to the dealer every three months for some other goofy problem. We aren't happy owners. Yes, its comfortable, drives great, looks good. But, it's big, can be hard to park, and has to visit the dealer far too often.

    I've had my 2008 R350 for a few months and it has just over 5k miles, until a few days ago everything was great. Within the last week or so the check engine light has come on and stayed on. Not that big of a deal in and of itself, but then oddly the outside temperature display on the dash started jumping up and down randomly. Two days ago I watched it go from +8 to -4 to +185 all in the span of about 5 minutes. Then when I filled up the tank from 1/4 full and the needle on the gas gauge did not move from 1/4 to full position for about 30 minutes, I thought maybe the tank had a leak or something was wrong with the pump. On top of all of that the key fob remote has become very unreliable - but only with one of the key fobs??

    Independently I would not be too worried, but collectively all of these happening within a few days of each other gives me some concern. Took it to the deal this morning and of course the check engine light is no longer illuminated, the temp gauge seemed to be working normally and haven't filled up the tank again. Just had a call from the MB Svc Mgr and he told me they had were able to diagnose some of the issues and replace a few sensors, that should take care of the check engine light & external temp readings and he was going to send the car home with a tech and fill up the tank to see if they could reproduce the fuel level reading. If he can then they would have to take out the gas tank and then replace some additional sensors for that as well.

    I am hoping that all of these are not representative of a larger issue...any thoughts?
  • james3686james3686 Member Posts: 2
    I have 06 R 350, at times the tail lights don't light and I get a read out " left substitute light on" other times it will be " right substitute light on" and sometimes I get a readout that both "left & right substitute light on" will be displayed. Running lights never light. Could it be the head light switch? Car has 50,000 K
  • ctdanctdan Member Posts: 38
    My post from 11/10 listed some minor problems which were "fixed" by replacing a few sensors, now a week later it looks like I am now in the club of the low voltage, power drain. When I went out to the car yesterday morning there was a constant beeping with a message on the dash saying something to the effect of "return to workshop, do not put in gear". When I put the key in, the car started sluggishly (low power) and then starting with all sorts of flashing waring lights. Also oddly the wipers went on by themselves - although they were in the off position. The car would not go into gear, either fwd or reverse. Called the dealer, they dispatched a tow truck to bring my R350 back to the svc dept. Not a good feeling watching a 2008 that was a few months old being hauled out on a flatbed.

    The dealer told me that there were too many codes coming up to clearly identify the source of the problem, but they did isolate the fact that underlying issue was low voltage. They initially replaced the battery and ran some overnight diagnostics to check the battery drain in the morning. This morning they told me that there is definitely a drain coming from somewhere, but not sure of primary source. They think it may be coming from the fuel pump since my last gas gauge issue identified in my 11/10 post. I find it interesting though that last week that was nothing to worry about and now they think it is the cause of the problem.

    After reading some of the other posts I do not get a level of comfort that they will be able to isolate and fix this issue as clearly there seems to be some kind of MB mfg default with no known resolution.

    Has anyone that has experienced this low voltage/electrical problem been supplied with an actual resolution, other then a new vehicle?
  • lcjdlcjd Member Posts: 2
    MB replaced our steering control unit 7 months ago and ,knock on wood, it seems to have resolved our battery drain issue. Make sure the steering control unit is from a previous year, though. Not a 2008.

    I agree, watching the flatbed tow our 2008 - 3 times!- was no fun!
  • ctdanctdan Member Posts: 38
    Thanks for the response lcjd.

    Interesting, my dealer never mentioned a steering control unit as a potential problem. What he did tell me though when I my car was dropped off yesterday with this low voltage issue is that he had another R350 in the shop w/a similar problem.
  • ctdanctdan Member Posts: 38
    Just had an update from my Svc Tech and he confirmed that they found the source of the problem and it is the ISM Motor of the Control Unit.

    A quick google of "MB ISM Motor" revealed the exact same problem resulting in the “DRIVE DIRECTLY TO GARAGE WITHOUT CHANGING GEAR” message that I received.

    They told me that basically what happened is that the ISM Motor is defective - this is the part that controls the paddle to shift from park to drive & reverse. The faulty ISM was preventing the car from shifting gears, hence the message above about driving without changing gears (a physical impossibility, but let's not split hairs). The drain came from the fact that problem with the ISM Motor prevented the car from recognizing that it was in park and therefore resulted in the repeated beeping and the dome light to be illuminated with no way to shut either off - causing the battery to drain.

    He is replacing the ISM Motor tomorrow, hopefully that will do the trick. I'll post an update if it worked... or didn't.

    I'm from Australia and this is my first post - I have a 2006 R350 which I purchased 7 months ago from a Mercedes Benz dealer. It is a 6 seater with "touring pack" which means that it has the removable console in between the 2nd row seats. I love the car, it has a couple of very annoying electrical bugs - thankfully not the battery draining issues that I have read about elsewhere on this forum. Firstly the 1 touch auto close on the sunroof doesn't work. When I use this feature the roof almost closes the reverses to a half open position. If I touch the button again it will then close fully. It will also close fully if I hold the button or if I use the key fob from outside the vehicle. So far the dealer has replace the wind deflector and the control module but the fault persists, the dealer is now saying that the rails may be warped and wants to changeover the entire sunroof cassette. Anyone else experienced this problem?
    Secondly, the auto light switch appears to have a mind of its own, sometimes turning the headlights on in the middle of the day in bright sunlight or refusing to turn the lights on at dusk or in low light conditions such as very heavy rain. The dealer has replaced the optical sensor but the fault persists.
    Finally, the front parking sensors seem to go crazy on hot days often emitting continuous tone and full led signal for several minutes for no apparent reason. This only affects the righthand side of the vehicle. Dealer says he cannot duplicate the problem.
    I would very much appreciate any advice or information regarding these annoying faults which spoil an otherwise excellent vehicle.

    Looking at 08 Rclass CDI's - anyone with the CDI 08 experiencing these issues? Guessing its all the same stuff just a different engine
  • StarTravelerStarTraveler Member Posts: 1
    Hi James,
    Did you ever find out what was going on with your tail lights? My R500 does the same thing. Also my horn has gone out. I'd feel silly if I took it in and someone tightened one screw and charged me $300. I'd love to know what was done to fix it.

    Thanks! Don
  • james3686james3686 Member Posts: 2
    Don

    Took the car to the local Benz dealer, they were kind enough to fix it free of charge, to me that's indication that they were having problems on many of the cars. If I understand the fix, it has something to do with the light socket making contact to the tail light housing, or lack of making contact. 50,000.00 miles seems to be the magic number, under that and they make a free fix. Spoke with another R350 owner that had the same problem with the tail lights. Can't help you with the horn problem. Hope this is of some help. Take care & travel safe
  • mbr352mbr352 Member Posts: 1
    My car now has 110,000 Miles. OMG! Major problems.
    Replaced steering column
    tail lights kept burning out
    cruise control went out
    windshield wipers went out
    The car would cut off constantly
    Harnerss wiring issues

    They tried to blame me (coin in cigarette lighter).

    Most of my work was covered under warranty. They even paid me out some money. After the warranty ended. They want me to pay. They have had to replace the fuse box.....maybe about $5500.

    Major electrical issues.
  • kommandantkarlkommandantkarl Member Posts: 3
    Hopefully my post can be seen by ctdan.
    I have the same exact problems about not being able to shift gears. I just want to know if the ISM Motor replacement actually worked or not.

    I have a 2006 R350. It just started showing this problem intermittently and is very annoying.
  • ctdanctdan Member Posts: 38
    CTDan here - saw your post and the ISM replacement did fix the problem, although the dealer had it for over 2 weeks before the could figure out what the root cause/resolution was.

    Since then I have had numerous issues unrelated to the ISM, the last one being a leak in the sunroof that wasn't visible in the cabin of the car, but apparently channeled down into the battery compartment which is under one of the seats. This caused the battery to short out every few days. Another trip on the dreaded flatbed (4 in 2 years) for another 2+ week stay at the dealer where they couldn't figure out the problem. I guess I'm lucky all of these ridiculous repairs have been under warranty. Just very, very poor quality vehicle.
  • dspicherdspicher Member Posts: 3
    We own the R320 CDI, and while generally we really enjoy the vehicle it has quality issues that we've never experienced in vehicles half the price of this one.

    Case in point - the tail lights. Tail lights on both sides have failed repeatedly. This isn't a matter of the tail lights burning out. This appears to me to be a design flaw in the tail light assembly that relies on pressure point contact between the tail light casing and the bulb socket to conduct power to the light (as opposed to wiring that goes right into the bulb socket). Over time, it seems that the contacts on the bulb socket bend to a point that they no longer make contact with the metal on the tail light casing (which I believe is conducting the power). We've "fixed" these several times, only to have them fail again shortly after fixing. (Interestly, other lights in the assembly rely on this same design but have not failed.)

    Has anyone else experienced this on their R-Class. I assume so given what our local Mercedes mechanic tells us (and the knowing shaking of his head when we present the problem to him).

    Appreciate any feedback from other RClass owners.

    Hi there,
    Just wondering if you can share some more information. We just bought a R350 2008, just over 4 weeks ago. Whole host of issues, including replacing front light within 1st 2 weeks. Most recent issue, is leaking sun roof that penetrated in to floor of car casuing battery damage. MB are stating not under warranty and looking for 9K to repair which is absurd. Any further information regarding your similar situation with sunroof would be very appreciated.

  • ctdanctdan Member Posts: 38
    How can they possibly claim that this is not under warranty?!? Tell your dealer to contact MB of Fairfield in CT and speak to John DeStefano, he was/is my svc advisor whom unfortunately I have gotten to know much better than I should have given all of the issues I've experienced over the past couple of years. If it has happened to me and you, I would bet there are others, and this is leaky sunroof/wet battery problem one of those "known issues" that they do no speak about externally.

    BTW my latest issue is that there is no longer any working audio... no radio, no sound from GPS, no ipod, etc.

    I am thankful that I replaced this lemon with a Volvo XC90 a few months back, which so far has been very positive. Doesn't ride as smoothly as the R Class, but at least everything works as designed. My R Class has been sitting in my driveway since there is no benefit for me to turn it in early.

    Good luck and please provide an update as to how it works out.
  • clynneclynne Member Posts: 1
    I have a R350 2007. I never had consistant problems other then the tail and front lights going out. I truly believe this is common with these vehicle. But once my warranty expired a couple of months ago, my Check Engine light has been on 3 times and the car seems like it's not going to stay on while it's running. Each tme I take it back they find that it has nothing to do with the previous problem (even though the symptoms are the same each time). I don't recall what the first diagnosis was, but the 2nd one was code 0703 Crank Sensor found faulty, the 3rd time they found code 0629 & 0633 which is some coil issues. Guess what today I'm having the same issue and the check engine light has returned. I'll be taking it in again the 4th time tomorrow and I'm sure they will find a few new codes to charge me for. Well I'm done.......I'm looking to trade this baby in.
  • motearsmotears Member Posts: 1
    Hey ctdan, are you still looking for help with your leaking sunroof/battery problem? I have an E320 that I experienced the same issue. There are drain tubes that run through both 'pillars' of the front windshield that drain the sunroof. In my case, these tubes became constricted with decomposed leaves. The draining water backed up but continued down the pillars, on to the floor, traveled almost undetected beneath the floor mats and found the lowest spot to collect - where the battery is located under the right side rear passengers seat. This is also the location of the main fuse box on my car. This cause numerous electrical gremlins! It's a good idea to run a piece of ridgid wire (co-ax cable) down these drain lines to keep them clear! :D
  • bautistabautista Member Posts: 1
    I got the same problem I have the 2006 R350 and it woun't shift gear, bad thing is, it's not under warranty anymore, can a local car repair fix this? How much MB dealer charge for this services like changing the ISM motor of the control unit. This is a headache!!!
  • ctdanctdan Member Posts: 38
    Hmm good question. Hopefully you have a local repair guy that you can trust. I do not know what MB charged since it was covered under warranty, but I cannot imagine it would be inexpensive. Good luck.

    BTW I finally turned my 2008 R350 back in when lease expired at the end of Feb. Good Riddance! I had replaced it with a 2011 Volvo XC90 which I have been driving for about 6 months & very satisfied with so far. Nothing spectacular, just solid, reliable, easy to drive, comfortable, no major drawbacks, overall a good value.
  • kommandantkarlkommandantkarl Member Posts: 3
    The best to fix it is REPLACING THE CAR!!!
    I changed it last November for a 2011 GLK350 Fantastic Ride and build like a tank, proudly made in Germany! absolutely no problem whatsoever.
    I lost money on the R350, they updated the software, and some other things but they could NEVER pinpoint the random shifting problems and shake ups.
    This adds up to alternator problems, early serpentine failure, battery failures, the panorama roof slowness, the random tailgate light problems, etc.
    And the last one before I traded in, the taildoor shocks were broken. Bill to fix those around a $1,000 that is when I decided to trade it in.

    Mercedes Benz dark ages of electrical problems between 2001 until 2007, especially the ones assembled in the USA.
    Finally in 2008 they increased the quality again.
    2006 R350 first batch of R350s it is like the Gremlins built those cars. I would stay away from them.
  • ccgwccgw Member Posts: 2
    I agree with the previous post.

    We got rid of our R350 (first year model) and we've been happy since! There were just too many electrical problems that it wasn't enjoyable car ownership with all these trips to the dealership for the annoying myriad of problems, mostly electrical.

    It's a shame as most Mercs do handle well, although my grip of the R350 besides being a bit underpowered for the weight, is the dim standards headlights (I couldn't get one with the HID lights with the one I bought at the time..)

    How are the GL's in terms of reliability and lack of trouble??? Test drove one and it was fine. How about the E350's??? Hadn't dared consider buying another Merc because of bad experience with our R350.
  • rcf8000rcf8000 Member Posts: 619
    I've had my 2011 GL450 for 3 months. I've had two significant problems so far, both electrical. The a/c intermittently quit supplying cold air, and the tailgate sometimes closes as desired but then opens, for no apparent reason. This has happened at least a half dozen times. I haven't gone to the dealer for the tailgate problem, but the a/c was fixed after several days in the shop. There have been a few other signs of electrical gremlins, too, but things that have occurred only once. My guess is that MB has not exorcised the electrical problems from these vehicles.
  • dr_grasshopperdr_grasshopper Member Posts: 1
    Hi There,

    I'm curious, what prompted the steering column replacement? I have a 2006 R350 and I'm starting to get a clicking and thumping that I can feel under the front floorboards when I make a turn. I'm trying to pinpoint the issue before taking it to my MB dealer. I'm glad I took out an extended warranty, I'm having lots of problems (I'm happy to post the list of issues if anyone is interested) including some possible transmission issues :( I love Mercedes but these issues combined with a lack of courtesy and friendliness at the dealership are making me wonder whether I'll ever buy another benz...

    Cheers,

    -Grasshopper

    My R350 cut off while driving on the hwy, was able to pull off to the side. Turned car back on and it would't go into gear, drive or reverse.
  • tasha40tasha40 Member Posts: 9
    Hi,
    Did you ever have a problem with the r350 not shifting into gear?
  • tasha40tasha40 Member Posts: 9
    Yesterday my 06 r350 cut off on the hwy, was able to get it to the side of the road. It turned back on, but would not go into gear, drive or reverse. Got it towed to my house, haven't took it to the dealer yet. Its not under warranty anymore, so I'm trying to see how much this is going to cost me. I've been reading alot of the same stroies, so I'm thinking its a low voltage issue, I hope.
  • samwrightsamwright Member Posts: 3
    My 06 R500 did exactly the same thing last week. Have you had anyone look at yours yet? What was the outcome?
    I took mine to MB dealer and they said I needed a new tranny (for $8200)! I'm getting a second opinion today.
  • springqueenspringqueen Member Posts: 1
    Hi, I just spent 6 hours today waiting for MB roadside assistance, and finally getting my 07 R350 towed to the dealer. The battery was dead, ( I think I left the parking lights on, but had problems for a month now with malfunctioning headlights) and the mall security folks tried to jump it off, using my manual to guide them in the correct points of contact. They used the wrong point - positive to positive, and all kinds of lights and warnings went off, and car would not budge out of park. Dealer service says it may have blown one fuse, or worst case: blown one or more of the computers on board. If so, big bucks :-(> Anyone have experience with non-authorized or non-dealer battery jumps and had problems?
  • tasha40tasha40 Member Posts: 9
    My car is at the MB, I had it towed there Tuesday, haven't heard back from them yet.I am scared to hear the outcome. Who has 8200 dollars to spend on a car to get fixed. That's just crazy. Did you get your second opinion yet, please let me know. I should hear from the dealer today and I will let you know. Do you plan on keeping your car, or should I say, do you plan on staying in the Benz family.
  • bluntblunt Member Posts: 2
    My car is making a sort of flapping noise, similar to a piece of paper slapping against something if a fan was blowing on it. Its like "flaflaflaflaflaflaflaflafla", and it seems to only happen when i get above 40mph?? sound familiar to anyone????
  • tasha40tasha40 Member Posts: 9
    Well the dealer told me it was the trans, need new one. The cost they talking is 5 grand, were going to get a second opinion. Should know something in a couple of days.
  • tasha40tasha40 Member Posts: 9
    Has anyone had any Transmission problems with there R350, took mine to the MB dealer they told me that I need a new one. 5 grand they talking, but I'm going to get a second opinion.
  • tasha40tasha40 Member Posts: 9
    Does anyone have problems with there front window button, you can put the window down but it wont go back up. Button is broke. What do I need.

    After a second opinion, was told that I did need a new trans (about $5K). Got the car back and running fine except the ABS and ESP indicators are still on? Took it back in today and had the speed sensor replaced. Fixed the problem. If you didn't get your tranny replaced yet, you may want to have them check the speed sensor. Sounds crazy, but I was never 100% convinced that I needed a new tranny. How do I know that the problem couldn't have been resolved by replacing the speed sensor? Why didn't the mechanic change the speed sensor first, before replacing the tranny?
    If anyone has any input, let me know.
