Cadillac SRX Loss of Acceleration Problem



  • lgray1lgray1 Posts: 1
    We own a 2004 SRX (V8) with 86,000 miles that we have been having problems with the Traction Control Light coming on since the day we bought the car just over a year ago. The light comes on, the car runs rough and then usually stalls. If I turn the car off to clear the system and then back on. SOMETIMES it will be ok… but not always. And it doesn’t work to turn the light off manually.

    We have had it in to our local garage two times now and it has worked fine when we get it back… but only for about a couple months each time. They have reset All codes.

    Any suggestions?? It sounds like others have had this same problem. I don’t want to drive it!! And I love the car…
  • Sarah,
    As I am reading all these posts over the: a) the stability control system, 2) the lost of power, 3) and all other non maintenance problems. I just bought a 2000 SRX with 56 1/2 K miles, I am wondering how pervasive is this problems, and , is GM about to issue any king of recall for all these frustrations the owners are complaining about?

  • I have spent all day reading all this post and hoping to find a solution before i take my car in to a dealer. We have a 2006 SRX and my wife just came hope telling me that the car just suddenly shut off and a message came up on the stereo control "Engine reduced power". The car could not accelerate and so she had to find a way to pull over and after a while it start and could accelerate again. But the engine light has stayed on since then. Has anyone had look with this issue so far. I really will not like to spend money and not get it fixed. Help!!!!!!!!!!!!!
  • Hi i was just reading your post and wondering of you could point me to where i could find information on the extended warranty you indicated. I am having the same problem.

  • Ok so my wife and I just rolled out of the Cadillac parking lot at 7pm w/ her new (used 2010 SRX Premium), heading I-95s and literally at 8:35pm we were on the phone w/ OnStar trying to get a tow because the Check Engine light came on as well as the "! Engine power is reduced" indicator. Words can't describe how p!ssed off I am, I realize we bought it used but from a Cadillac dealer.

  • So Moore Cadillac calls us yesterday apparently the SRX checked out they couldn't locate and problem, today my wife is running errands w/ our new born (7 week old daughter) and right in the middle of Rte 1 "Engine power is reduced" causing my wife to instantly have to pull over to the side of the road. Now i'm researching Va Lemon Laws because it hasn't even been 48hrs since we bought the crossover and already twice w? the same message. I'm sure after we get it towed again this time further away that Moore will run the code say they didn't see anything have a nice day. God forbid my wife and baby get into an accident behind this its a Lawsuit waiting to happen.

    I have a 2006 Cadillac SRX. Since I have had the car 4 times, it will just start spitt and sputtering down the road, won't hardly go. The check engine light will flash. We have took it to a dealer, and independent mechanics, the computer shows miss fire, nothing wrong with the car. It will go good for about 3 months and then the same problem all over again. I have spent a fortune on everything but the problem because no one can figure it out.
  • Hi there, I just wanted to let everyone know that when engine light came on it was because of a bad gasket which got replaced then the engine light continued on so our mechanic said it was the accelerator chip that needed to be replaced. We are replacing that tomorrow however they said if its not the chip then its the whole accelerator, I guess we'll see tomorrow.
  • Is your Mechanic in San Diego? I had the same problem with my 04 SRX
  • I own a 2012 SRX. After nine months and only 6000 miles, the car started to hesitate upon acceleration. It would slowly roll me forward and then jump suddenly as if I were peeling out. This has left me and my family in very scary situations. Pulling out into traffic is frightening because you never know if the car will respond as it should. This does not happen all the time. But once was plenty. It has occured at least 15 times. I have taken the car to the dealer 3 times for this same problem. The second time, they actually admitted that the car did it, but that it was only slightly? I was informed after 4 days with my car that the dealer now has a piece of paper that lists my Model, Make & Year car as having this known " Characteristic". Within minutes of retrieving my vehicle from them, it did it again while exiting their drive way! My Father and I were almost struck by a truck. I contacted their service department immediately ( from my car) and told them what had just occurred. I asked if there was video of their driveway and was told yes. I then requested for someone to go see what happened just then. I was told that it was not necessary, and asked to bring the car back again. I did so and left it for a week. They drove it 44 miles and had no problem, so I'm on my own dealing with this. I did contact GM from the beginning..... Worthless all the way through. They call and act like they care and are there to help.... But it's all lip service. The GM contact (Cindy) @ 866-790-5700 x 41084 repeatedly would say "no problem" , what???? This is a problem! I have personally owned at least 15 GM vehicles, and this will be the last. My two businesses have fleets of GM trucks. This too will change. I can't believe that GM will put me and my family in danger to save a dollar. Its very disappointing that they don't stand behind their product. This vehicle is NOT fit for the purpose it was sold!!!! GM needs to step up and do the right thing. All I want is for my car to be fixed, not excuses about characteristics. If it were characteristic, it would not have waited nine months to start showing. I would have noticed it from the beginning. GM case 71-1226526070.
  • Ralf Nader should have waited to do his thing with this POS. "unsafe and no speed" and in my opinion this is the worst car ever made. My wife bought this car new and still have it today and trust me not because we want to. We have dumped more money in repairs into this crap wagon than we paid for it new. The local Caddy shack by us knows us by our voices on the phone. And now that the government owns GM I'm sure the people who own these rolling money pits will never be taken care of. We can't even trade this pile in no one will take it and now it is putting itself into low power mode and engaging the stability control at random! I currently have it for sale locally but don't feel comfortable selling it to anyone except a child molester. Thanks for ruining our life GM!!! No joke!
  • I purchased a 2013 Cadillac SRX at the end of January. Around September, I was told I had 3 recalls and a system update. About a month or so after the repairs, my car started to lose acceleration. The car would jump and then lose acceleration for a couple of seconds. Took the car back into the dealership December 2nd, and they could not replicate the problem. I googled the issue and found 2 forums with customers having the same issues. I showed the dealership the forums and all they said was, "hmmm, we will have to do more research, because there's nothing we can do." 2 weeks later I was at a four way stop, and the car lost acceleration again, and I almost got hit by a car. Called the dealership back up and explained how unsafe the car was. They said the only thing they could do is drive the car around until the problem was replicated. I contacted Customer Service, which turned out to be a complete waste of my time. I was told I would receive a phone call from a customer service manager within 24 to 48 hours regarding the issue. A week has gone by, and the service manager never contacted me. In fact, he told the service agent to deal with it. According to my service agent, my issue has now come "full circle". He has now said driving my car around to duplicate the problem would be a waste of time since I've only had 3 issues this past month. He did finally agree to put a monitor on the car for a couple of weeks to see if it can read any problems. $50k is a lot of money to spend on a car which is CLEARLY unsafe to drive. I've never experienced customer service this bad in my entire life. My family and business will not be purchasing any more GM cars, in fact, I will be trading this car in if the issue is not resolved promptly. I should have known better, and gone with the Lexus.

  • Please add me to you list of people having the same problem with the 2010 Cadillac SRX. We had our car tuned up days before leaving on a road trip and the car was fine. I am on a trip from Arizona to New Orleans and back to Arizona. We had the engine losing power problem on Rt 49 heading to NOLA a few days ago. I pulled the car into the break down lane and after shutting the car off when restarted it drove fine but the engine light remained lit. When we arrived in New Orleans and the car was restarted the engine light went off. Now driving back to Arizona on the same route in approximately the same area the problem reoccurred. The only other place we had a problem with this auto was twice at Route 66 casino in New Mexico one year apart where we were not able to start the car in the morning after staying in the hotel. In those instances our OnStar service also would also go out. I have noticed that in most cases dealers are not able to determine what is causing this problem might it be an external electronic signal effecting the engine?

    Would anyone like to forward an opinion as to why Cadillac is producing such poor performing vehicles nowadays? i have read all the posts and the litany of complaints is amazing. I just want to understand why Cadillac, once at the forefront of engineering excellence is at the back of the bus now.

    Well, it's a "problems" discussion. People typically don't take the time to brag on their cars anyway, but when something breaks, they like to vent.

    That said, JD Power Circle results are "only" 3 stars for the SRX and CR says the model has "declining reliability". This USA Today story is a bit dated, so you may want to hunt around for newer numbers if you are in the market.

    For the newer models, it'll take a while to see if the stats have turned, what with GM coming out of bankruptcy etc.

    I have a 2004 SRX and I have been having similar troubles. Does anyone know if there is a updated wiring diagram for the Throttle body & harness connector? I have replaced mine, and still doing the same things. I have also replaced the Throttle pedal & the ECM.

  • I am experiencing the same thing with my 2005 SRX. My car looses acceleration when I am driving. It has shut down twice while driving which is scary in Dallas traffic. Engine light comes on and I have gotten a "theft error code" twice. A couple of times it has "jumped" when I hit the brakes to stop like it might be a problem with antilock brakes or transmission. I have had it to my mechanic twice and to the Cadillac Dealership three times but they have not been able to find the problem . It does not show any error codes. They told me they need to see what it does before they can fix it but it doesn't happen consistently so I am in a Catch 22 situation. My car has problems that need to be fixed but nobody can seem to find the answer. I am afraid to drive it and don't want to sell it to someone else with that kind of problem. It is dangerous.
  • My story sounds so familiar after reading all these posts. I have to say I am very dissapointed in Cadillac/GM. After researching for the last couple of days on a solution, it is sad to say the only solution is to get rid of it.
    I just posted this on yesterday :

    I purchased my used SRX in May with 39,000 miles, no problems. I drive it 4 days a week about 60 miles to and from work. It now has about 56,000 miles (warranty is over). Early November I was driving home from work with cruise control on 70 mph, when I ran over a small branch. Immediately lights started flashing and the car started slowing down. I remember some of the messages/lights were "service stabilitrak", "check engine", "traction loss", "engine power cooling", "fuel saving mode". I pulled over on the side of the road and my car began shaking at this point so I turned off, stepped out and checked for smoke, flat tires. There was nothing. I turned the car back on and the check engine light was on but I drove it home anyways since I was close. The next day I drove it to my local mechanic, but before I made it there, the light turned off so I went home.

    In the next 3 weeks, I had the exact same incident happen at least twice/week to/from work. Finally 2 weeks ago on my way to do some shopping, it happened twice and that was enough. I took it to the nearest Cadillac dealer and they said they would check it and give me a call. I got a rental and went home. This is what they found:

    DTC - P2138 "Found accelerator position pad intermittently inop"

    "Replace accelerator position pad"

    Nothing else! Total was $365 labor/part

    I picked it up this last Wednesday since they had to order the part. Drove it to work, home, everything was fine. Problem solved (i thought).

    On Saturday I was on my way to pick up my family from the airport 2 hours away. I didn't even make it half way before the same problems came up. So again, I pulled over, turned off the car, turned it back on, kept going. After the third time it did not want to move anymore. As soon as I turned it on, it immediately began shaking, engine power loss. HORRIBLE!!!

    I had to call a tow truck and just my luck the nearest cadillac dealer was a different one from the previous. They said they would check it Monday and call me back. (I'm waiting)

    I called the original dealer from last week and they said "they fixed the problem they found". So i'm assuming they do not plan on giving me a refund for not fixing the actual problem.

    Update: I spoke to the new dealer yesterday and he said they needed to replace the "throttle body". Luckily he said this will be covered under powertrain warranty.

    However, I have decided to just trade it in for something else. I know i will lose money since I just got it in May but I can't imagine going through all this again.

  • I have a similar situation. My 2010 Cadillac SRX (about 90,000 miles on it) recently died 4 times in a row on my way to work. The check engine light came on, "service stablitrak" appeared, and then "Engine power is reduced". I completely lost power on the interstate and had to coast over to the side of the road. I shut it down, and was able to restart it after a couple tries. I brought it into the dealership, and the mechanic said error codes appeared for the timing chain and throttle body. The quote for repairs is $1,900. After reading these posts, I'm concerned that these repairs aren't going to fix the loss of power issue. I'm pregnant and driving a 2 year old in this vehicle, and I want assurance that it is going to be safe to drive!!!
  • I have a 2009 srx4 and in the middle of me driving .it just lost power the dash says engine power reduced can somebody help me

  • Don't waste your time on this forum. No one is giving answers. Don't email any of the emails on this forum either; they are only there to push you to go to the dealership to drop thousands that doesn't fix the issue. The real issue is more related to the TPS, P2135, P0638,l which freaks out the ECM and causes a whole lot of other codes, like Cadillac only C0242. The TPS connector sucks and gets baked with heat, which fatigues the pins and plastic. Get a standard motor products S1057, NOT from the dealership, acdelco or any of the other places that charge 4x for the same part. What happens is that the ECM loses track of where the TPS is and instead of like Toyota, they default to limp home mode, where there should have been a redundant system to prevent such a dangerous scenario.
  • I just paid a ton of money to replace the alternator on my 2007 srx. That waswas over a month ago. Now, I'm getting battery charging system errors, stabilitrack messages, engine light on, tire pressure errors etc. Parts of my body control module is burned out and a majority of my inside electrical is non functioning. I regret the day I purchased this vehicle because it's just been one headache after another
  • I have also had the this problem the traction light comes on then the stability light then car turns off while driving or upon acceleration the engine reduced light comes on and  I'm stuck in the middle of traffic with my children in the car very scary ...I have called and tried to take it in to Cadillac dealership and they said they would not be able to look  at my car because its to old I have tooken it to several mechanics spent a lot of money and they can not find the issue it is very frustrating because I'm a single mom and this is my only vehicle and Cadillac or Gm are not willing to look at it ...
  • I am having the same exact problems with my 2004 SRX and very frusterated. TC light and power reduced and stability control, all that. Almost got rear ended 3 times now. The vehicle is a perfect fit for my family but I'm sure there is a better fit that isn't a Cadillac with so many issues. I'm trading it in and will not be Recomending Cadilac to Anyone!
  • You'll get a kick out of the reply on this one..... I have an 05 SRX. about a month ago my car just lost power driving home from work. the check engine light came on and service engine soon message appeared on screen. I took the car to my mechanic and the code was for a Throttle sensor. He changed that $400. I got the car back and a week later had the same issue. He checked it out and thought that because of the misleading codes it was the Batterie. Got it back and it broke down the next day. This time after having my car for 2 days he found out that If I drive my car for about 25 to 30 minutes it will break down. If I turn it off for a couple minutes than I could drive for a few more minutes before it happened again. the car accelerates very very very slowly but will eventually get up in speed. He could not figure out what the issue was and told me to take it to Cadillac.

    I dropped my car off at The Cadillac Dealership and got a call back a few hours later. With the engine light on, loss of power, and service engine soon. They told me that my rug on the drivers side had bunched up under the gas petal and that's what the issue was.

    Do not buy a Cadillac, Do not let your friends buy one. They build engines out of tin foil and rubber bands and don't know how to repair a rubberband
  • My husband financed me a 2004 Cadillac SRX because the Chrysler he traded it for was having issues as well.and wouldnt pass emissions. The Cadillacs check engine light came on about 3 months after purchase and of course after it passed emissions and we purchased plates. There are about 25 different codes for the check engine light but along with those problems, the traction control light comes on perdy often and the power to the engine stops almost completely after jerking a awhile.I have to pull off to the side of the road and upon restarting the Cadillac it usualy fixes itself after a few tries or letting it sit 10 or 15 minutes. I have almost been rear ended several times now because of this problem, its very scarey in heavy traffic of Ft. Collins and I Pray everytime I get into the car with my grandchildren because it is my only transportation, that something doesnt happen.This problem is very dangerous and it just seems like it should be a Cadilac recall but from what Im reading and researching, Cadillac doesnt seem to be taking responsability for the problem. We have fixed several different things on it including throttle body position sensor other sensors, have had to replace the alternator and battery because there is a loss of power and other things. I will continue to read up on this problem on every web site possible in Hopes to find a fix for this obviously common but frusterating problem that GMC has left for thier customers. Please leave any helpful information and Safe driving everyone!!!
