Lexus RX 350

    kwbuggy, many thanks for your reply.
  • My mother purchased a new 2011 Lexus RX 350 last spring. The dealer installed a remote starter at the time of purchase (we live in Alaska). My mom does not drive it very much (2 miles round trip normally) and often does not drive it for several days. The battery drains if the car is not driven for a week. Installed new heavier duty battery. Dealer says everything is within tolerences electrical usage, but noted the remote starter was drawing more that it should and "reinstalled". Dealer suggested and installed battery tender, and that works if we have some place to plug in. If we can't plug in (like at the airport) the battery is drained in 4 days!!!

    The Lexus dealer has no clue as to how to deal with this and says nothing is out of the ordinary. However, we can't believe that having a dead battery if you don't drive the car for 4 days is what to expect from Lexus.

    We are about ready to tell them to take the car back and we'll go to a different brand.

    Any ideas?

    We're seeing more and more of these complaints. Lots of gizmos draining power in newer cars. For example:

    nobmw3, "BMW X3" #4176, 27 May 2012 2:04 pm

    Seems like remote start systems are about as problematic as aftermarket alarms. I'd disconnect it and see it that helps. Plus when I lived up there, I found that the car warmed up faster if I just got it and drove it.
  • How difficult is it to disconnect the remote start? My mom is 76 and lives 120 miles away from me. Is it something I could walk her through?

    BTY, my brother thinks that she should have gotten a BMW instead. Looks like they are having the same problem looking at the link you gave.
  • steverstever Posts: 52,683
    Beats me. Perhaps if she can get it back to the dealer, they'd give her some kind of credit or not charge her for disabling it.

    I have a sinking feeling that the problem will still exist though since the car isn't driven much.
  • Thanks for the advice. I'll have her consult the dealer the next time she is in town.

    Looking the "Club Lexus" Q & A site, this is a problem with several Lexus models. The "smart key" also seems to be an issue at times.

    We do have the battery tender installed, which works when she is home. Just trying to get it so she can leave it for a few days and not worry that it will be dead.
  • steverstever Posts: 52,683
    Maybe a solar trickle charger on the dash would do the trick, at least for the summer months up there.
  • The Smart Key function is easily disabled and you certainly should try it and see
    if the short battery life symptom changes. Everything including the remote start
    will continue to work but you will need to actually push the fob button to unlock
    the car instead of just approaching with the key in your pocket. Once in you will
    then need to hold the fob quite close to the Start/Stop button while pressing it.
    You can then return the fob to your pocket.

    The change is a menu item using the right steering wheel button on non-Nav
    cars or the Settings Menu in the Nav cars. I am assuming that the Remote Start is
    the factory module installed in the correct port and not an AfterMarket type. You
    press the remote "lock" button three times and hold it til the lights flash, right?

    Has anyone got their RX350 serviced at a "Toyota" dealer instead of a "Lexus" dealer? Two reasons I am entertaining this thought: the Lexus dealer is 35 miles away; Toyota is right in town. Second reason: cost.

    Second question: you know that antenna that is on top of the car, about 6 inches in front of the rear windshield, kinda shaped like the tail of an airplane?: if you take your car thru a car wash, will that antenna be able to handle it or do I only go thru touch less car washes?

  • pschiffepschiffe Posts: 373
    1. I go to a Toyota dealer for most all my Lexus RX service. Same parts and level of competency at about half the price. No free loaner, gourmet breakfast or quick-and-dirty car wash but I can live with that.
    2. You should be OK with that antenna, mine has the fold-down style located at the right side near the luggage rack and was in fact damaged by an automatic car wash. I now take special care to unscrew and remove it before entering. I suspect the new design should be immune to such damage.

    A couple of months ago I came home to find my windshield of my 2007 rx350 was cracked right where the sensors are and the rear view mirror was hanging. The car was obviously not vandalized because the cracks could not be felt from outside or inside of the car. There were no other signs of damage other than the hanging rear view mirror inside of the car. The car was locked and parked as I left it. It happened to be an extremely sunny day and my conclusion was that the sun must have caused the sensors to overheat some how which caused the glass to crack from inside. Of course the dealership said the haven't heard of this. I was able to have someone glue the rear view mirror on and figured I would worry about replacing the windshield later. Well, today we experienced temperatures near 100 degrees. My car was parked in the usual place except this time the rear windshield was facing the direction of the sun. When I came home the entire rear winshield was shattered. Again, no signs of vandalism. Just shattered glass in the trunk no rock no nothing. Again I'm thinking the sun caused the sensors along the rear windshield to overheat causing it to implode. Can some help me? Did this happen to anyone else. Contacting dealer in the am.

    Many thanks for sharing your experience.

    Good to hear that I have an option here.

    If they have to replace any parts, does the Toyota dealer use "Toyota" parts or do they procure "Lexus" parts? I am guessing that from your perspective it doesn't matter. But I am just curious.

    Thanks in advance.
  • pschiffepschiffe Posts: 373
    Toyota Parts = Lexus Parts in most cases. On occasion the Toyota dealer may source certain parts from the Lexus dealer, aftermarket parts are never used in my experience. No parts substitutions should ever be allowed without your specific authorization.

    Pschiffe, many thanks for clarifying. Excellent info to have. I wasn't aware of the "no substitutions without permission" standard expected from dealers.

    I recently took my '07 RX 350 in for service. I complained (again) about the severe engine noise on start-up. Long story short, I'm going to be out $3,000 for cam gear replacement! Lexus says this is a deal as they are paying for 50% of the parts. I believe that this is a quality issue and they should pay for much more. Does anyone know how to escalate this issue? Have others had this cam gear issue?
  • kwbuggykwbuggy Posts: 11
    Wow this sounds extreme! How many miles on the engine and what were the warning signs that the cam gear was wearing out? Have you owned the car since new or could a previous owner damaged it by neglecting oil & filter changes?
  • kwbuggykwbuggy Posts: 11
    I just checked all of the 2nd and 3rd generation threads on the Club Lexus website and only found one mention of this problem. It occurred in February 2010 to an RX350 with 45,000 miles on it. It is apparently a known issue with a few engines. Look at the posting yourself and then try to get the dealer to pay some more of the repair costs. The poster on Club Lexus had his repair done totally under warranty but of course the car only had 45K on it at the time and was only 3 years old.
  • aart2aart2 Posts: 2
    I am 3rd owner. Just over 80,000. Previous owner bought as certified pre-owned and I know the previous owner was religious about regular service. I have been arguing for Lexus to cover more. They agreed to 50% of parts cost, but it'll still set me back $3,000.

    This is my 4th rx, 2004, 2006, 2010, and now a 2013. The 13 runs just as good as
    any of the other 3 and uses regular gas instead of premium. Same engine since 2007, why did it take so long to do this?
  • wwestwwest Posts: 10,706
    If you go back and look I think you'll find that NONE of your previous RXes REQUIRED premium fuel. Even my 2001 Porsche C4 will run happily on regular.
  • cwaynecwayne Posts: 81
    My previous RXes seemed to run better on premium gas. (mayby my imagination). On my 2010 RX I filled my tank with mid-grade and the
    check engine light came on. I called the dealer and he said mayby a bad tank of gas, sure enough I filled with 93 and the light went off. I had used mid-grade before with no problem.
  • I have recently purchased a rx 350 -2013 with premium package. I like the interior but I noticed the hand rest in the backseat does not have a wood trim. But shows the back hand rest with a wood trim. My dealer insists that its a error on ; wondering if any of you guys have the same ?
  • I recently purchased a RX 350 premium package (Parchment/MapleI Interior. I noticed after I drove drove home that back seat hand rest does not have a wood trim as shown on

    Dealership's explanation is that has a wrong image .

    Appreciate a response from anyone who has a similar interior.
  • Hello, everyone,

    I have really enjoyed reading this forum and appreciate everyone's openness.

    I'm in a position where my car has died on me and I'm going to need to purchase a new car. I had been researching cars anyway so I don't feel too stressed. I'm leaning toward a crossover or small/med SUV to purchase.

    I'm trying to decide whether it's better to buy a fully loaded "regular" car (toyota highlander, ford edge, etc.) or spring for the luxury car. I've been looking the Audi Q5, BMW X3, Infiniti EX35 (or 37 for 2013) and the Lexus RX350. I can afford the luxury cars, but just wondering if it's worth it. I have driven them all and like the RX the best, followed by the EX35 and the Q5. Just trying to be smart about the purchase and think about long term effects like reliability, maintenance costs, etc.

    What made you ultimately choose the RX350 during your selection process? Any insight would be greatly appreciated!
  • wwestwwest Posts: 10,706
    I purchased an RX300, '00, since it quite clearly has a functional F/awd system plus an actual LSD. I traded up to the '01 RX300 to get HID, VSC, and TC.

    Big, BIG mistake...!

    As of '01 the VC fluid was reformulated such that it always remained FLACCID, NEVER any substantual level of engine torque coupling to the rear...


    After the fact, once the front driven wheels LOST traction, then TC would activate, simultaneously dethrottling the engine FULLY, and braking the front wheel to simulate traction. Yes, this serves to force engine torque through the fully open center diff'l but with the engine now idling they is virtually NO TORQUE at any wheel.

    Since the TC system makes a VC totally useless Lexus dropped the VC from all future RXes.

    Now, with the F/awd system fully non-functional Lexus finally caved to the owner outcry and provided a TC "off" capability. Now you could at least "feather" the throttle to get up and going on a slippery surface even with only the front wheels being driven.

    My advise to you would be that you should take a serious look at the Toyota Venza w/I4 engine. The Venza actually preceded the RX350 in adopting a new F/awd system. You can easily modify the Venza to have the front wheels "freewheel" via an aftermarket TOAD kit. Then apply a constant 12 volts to the ear clutch and you have a RWD Venza
  • Aftermarket gps units can be mounted on the dash with mounting tape (grey double-sided adhesive tape, sold in hardware stores such as lowes or homedepot in small rolls). Suction mount only works on glass and has to come off. All dashes differ in their shape so check if any component of the gps suction mount piece can be detached and reused to help install the navigation unit on the dash more securely. This unit stayed securely in place since the time of the original post (nearly four years) until replaced with another gps unit with more updated maps for 99 dollars.

    I use a bean-bag type mount which stays in place but can be easily concealed when not in use to thwart theft. :)
  • I have a 2013 2wd rx350 how would I get the snow track switch to the on position..
  • My short 85 year old mother had a wreck yesterday and we are now car shopping. I am interested in a crossover type vehicle that is low enough that she won't have to climb up to get in but is higher than a regular sedan so she won't have to pull herself up to get out. What is the height of the driver's seat from the roadway in the 2013/2014 RX 350?

    Hello everyone! I have been considering picking up an RX in the neighborhood of a 2004-2007. These have something in the neighborhood of 120-180k miles.

    I need something that is quiet and isolated and all of my research shows nothing beats the Lexus RX. I never in a million years thought I would consider something that is relatively mushy with no feel for the road as I love to drive. However, I have chronic migraines and hyper-sensitivity to many inputs and everything I read indicates the RX offers the most isolation for an SUV.

    I have been driving a Celica since 2000 and boy oh boy, try loading a drumset or heavy guitar amplifier into this hatchback with the high lift-over, aka one must bend way over to get the heavy objects into the vehicle. That has been deadly for me, and now I am old enough where such could actually finish me off :'(

    I have a great independent mechanic and do not mind repairs & restoration. My experience is the used vehicle is always less expensive in the long run than a new vehicle. (I would not buy a new Lexus for sure, it would be something cheaper if I did buy new.) I have read everything about these vehicles and understood that a used vehicle may need a tranny, struts, power steering rack, or any combination of these.

    I just read the 400H forums, and wow, scary! Those just seem to be too high risk. Even if the volume of complaints is relatively low, any $5,000 repair is something that would not make financial sense. So although I think the latest technology is very cool and wanted to participate, I cannot see buying a hybrid.

    I love the black and white versions of the RX, and the black is best. This vehicle would need some mean aftermarket wheel to take some of the femininity out of the vehicle. That is doable.

    The existing car is a problem. I don't have room for extra cars, but I would hate to sell it. I have kept it in perfect mechanical condition, replacing things as new along the way. That means the $4,000 market value makes selling it a poor financial move. Maybe I will keep it as the Sunday joy ride. Not sure how to work that out yet.

    The thought crossed my mind to pick up a southern car. Nowadays I just plan on keeping vehicles forever, so taking a perfectly clean car and restoring the mechanicals makes a lot of sense. Although people do tend to keep their Lexus vehicles quite clean, given the battering and rust the wheels wells of my Celica have taken here in Ohio, the allure of a rust-free southern car is quite strong.
