Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: There are a fair-number of power steering related complaints which is a continuation of problems from the previous model year. Considering the problem tends to happen beyond the standard warranty (73k+) it's best to avoid this vehicle or at least be prepared for the $1,300+ repair.

Traverse 6-cyl

  • 85,000 miles


While driving, the vehicle suddenly showed alerts reading traction control off, service traction control, service stabilitrak, and engine power reduced. At this time the vehicle immediately slowed down to 20mph. Thankfully my toddlers were not in the car and I did not have traffic behind me so that I could safely pull over to the shoulder. I turned off the vehicle for a few minutes and restarted again, at which time the same errors returned with the exception of engine power reduced, so that I could at least make it home. I immediately called my Chevy dealer who completes all service on my vehicle, and I was told that this is a common problem, especially in the cold temperatures as oil tends to accumulate in the throttle body and freeze up, making the sensor go haywire, leaving the throttle unable to compensate for the changes, and the warnings to occur. I was told it would not be covered under the powertrain warranty and that there was no recall. I was also told that it wasn't a big deal and it should be fine when it warms up. I guess we differ in our opinion of whether a car shutting down in the middle of the highway or with my children in the car is a big deal. I guess we also differ in our opinions about whether a $40K vehicle should function in freezing temperatures that occur for four months of the year in the northeast. Chevrolet has issued recalls for this very issue with many other vehicles and some years of Traverses but not all. Chevrolet, you need to stand behind your vehicles...take responsibility for the $100 part that can very easily be fixed in 15 minutes time instead of forcing customers to drive an unsafe vehicle or shell out upwards of $600 to make the repair. I love this car, probably my favorite vehicle I have ever owned, but this is a major problem.

Traverse 6-cyl

  • 87,000 miles
On six separate occasions in 7 days, my vehicle has displayed the following messages, traction control off, check stabilitrak, and reduced engine power then suddenly reduces speed significantly unwilling to accelerate. I have to pull over, turn off the car and wait several minutes before I can turn the car back on for it to drive correctly. This is extremely dangerous and I know it is a recurring issue for many GM 2010-2012 vehicles and no recall or solution has been made yet.

Traverse 6-cyl

  • 86,000 miles


While traveling on the hwy at 65 mph I got a message on the dash that read "service traction control" then "service stabilitrack" then "engine power reduced" all simultaneously. Then I lost power and went drastically from 65 mph down to about 40 mph. I almost got ran over by a semi truck!! I pulled vehicle to the side and slowly made my way to the nearest exit. Once I got off the hwy I tried to make my way back home, but the power was reduced to a crawl, so I pulled into a parking lot and ended up having to get it towed to the shop. They diagnosed the car and found no mechanical issues, only what seemed to be a "glitch" in the computer system. Suggested that I may need to replace the throttle body. I picked up my car and it drove fine for 5 days then it did the same thing again, luckily I was in my neighborhood. Drove it home and parked it. The next morning it drove just fine, no issues, and today it happened again. I have spent the last few hours reading hundreds of other complaints describing the exact same scenario, and found that they are taking their vehicle into the dealer and getting parts replaced only to have it happen again and then more parts replaced and it continues in this cycle... this from only one forum and there are a number of others a like!

I was driving at about 50 mph when the "stabilitrack system" "reduced engine power" "service stabiltrack" errors went off which reduced my speed suddenly to 20 mph and I had to pull off to the side. This could have caused a major accident had I been on a highway, thankfully I was not. After doing some research this is a common problem with Chevy Traverse's and GM should issue a recall for this part. I had to pay out of pocket to replace the throttle sensor and body and GM will not reimburse me. It's also not covered by their powertrain warranty.

It has to do with power to the engine being reduced. It has happened to me three times. Each time, I received three error messages ("traction control off", "service traction control", "service stabilitrak"), each time power reduced to my engine, and each time I paid substantial sums to the dealer to have it fixed, but each time it happened again. The first time I paid dealer #1 about $150 (if I recall correctly) to have them clean carbon from a sensor on the throttle body (which, coincidentally, I've had several problems caused by "carbon", according to the dealer #1). The second time, same thing, but paid only about $45 (to dealer #2 because I was out of town). The third time, I paid $600 for a completely new throttle body, including all of such sensors, from dealer #1. I am not confident that it is any safer now than it was before, since the track record is so poor (neither of the prior fixes solved the problem). Two of the three times (time #1 in January 2014, and just now for #3 in January 2015), I was on the highway at a high rate of speed, and fortunately the cars behind me were able to swerve and avoid rear-ending me at the last minute.

I was driving along at 60 mph when my traction control light turned off, followed by "service stabilitrack", followed by "reduced engine power" and my vehicle went from 60 mph immediately down to 15 mph. If I were in heavy traffic or had any vehicles following me, this would have caused a major accident and potentially serious injuries, to me, my 1 year old son and whoever was behind me!!!

Traverse 6-cyl

  • 52,000 miles
While traveling on local road in my town, I was traveling about 30mph when all of a sudden the service traction control light came on and I lost power with speed being reduced. Thankfully, no one was behind me so I was able to control where I would stop the vehicle. I returned to my house and went on line to see what this problem was and saw numerous complaints from other Traverse owners with regards to the same incident occurring. From what I have been reading, Chevrolet is aware of this problem but doesn't seem to correct the problem. There have been numerous reports of this happening on major highways where the speed was much greater than mine and thankfully no one was killed. Car will be going in next Tuesday to dealer for hopefully correction of this problem.

Use remote starter. After a few minutes of warming up unlocked and entered vehicle. Once key turned to on doors started to lock and unlock. Put car in reverse barely moved. Tried drive and would not move? check engine light, stability track lights are on. Not good when you need to get to work.

2011 Chevy Traverse is having fuel gauge issues. GM has a recall out on 2014 models, however my 2011 is experiencing the exact same problem but no recall for that year. Per GM this can result in the vehicle unexpectedly running out of fuel and stalling, increasing the risk of a crash.

Traverse 6-cyl

  • 74,300 miles
Traction control turned off, stabilitrak trak turned off and then it said they needed service, immediately after it then started down shifting and quickly slowing itself down. It is a real hazard on icy roads and on the interstate in traffic when the vehicle quickly slows itself down. Many posts on the internet with this problem repeatedly occurring with multiple repair attempts at dealerships. I'm starting on my 2nd trip to the dealership. This is a definite safety issue when the car takes control and slows itself down. By shutting off the car it will reset the system and then it will work properly for a while. But this problem keeps recurring after it has been driven for a while.

I bought a 2011 Traverse last winter. I was so excited about my new family car. Wednesday, the service stabilitrak, service traction control and reduced engine speed came on with no notice. Luckily, I was on a neighborhood side street taking my kids to school. I called to setup an appt to have a Chevy dealer look at it but after turning it off while filling the tires up the lights all went off. Called back to see if they still wanted to see it and they said no because it must have just been a sensor... appt canceled. Thursday drove with no problems. Now today, Friday, I hop on the expressway in Chicago traffic and bam right as I am merging, ding ding and my car just revs and won't get up past 40 mph, all the same service lights came on. So scary! I have my little kids in the backseat and terrified to pull over on the side of the eisenhower, slowly get to the next exit as I pray we won't get rear ended. Call as soon as I make it home for another appt and the first time any Chevy dealer near me has open is 4 days from now. Looks like we will be parked at home for the next 4 days. It really frustrates me that we bought this "reliable family vehicle" that I am now scared to drive my family in. It's even worse now googling this issue and seeing many other having the exact same issues and nothing is being done for us.

Traverse 6-cyl

  • 67,000 miles
Stabilitrak control, anti lock brakes and engine speed reduced. Wife's car while on her way to work. There are hundreds if not thousands of consumers with this exact same issue with various makes/models of GM vehicles. Once the throttle body / throttle positions sensor becomes dirty, it sets off a series of failures causing the vehicle to reduce power to the point where it can only travel at about 35 mph. This is a very dangerous situation to place drivers in. I called my local Chevrolet dealer to inquire about whether or not this was covered under the 5 year 100,000 mile power train warranty and was told that it was. When the dealer verified that it was the throttle body, they told me that it would cost me about 500 dollars and that it was not covered under the powertrain warranty. This is a vital engine component. How can it not be considered to be part of the power train?

Four times today as I was driving my Chevy Traverse the traction control went off, the stability control went off, and a message flashed that I could experience a reduction in power, which happened immediately after the notification. The car barely had enough power to make it safely out of traffic. This happened one other time last year but when we brought it to the dealer they could not replicate the problem.

I was driving the truck on the main street when the truck just turned off, everything shut down even the radio...checked the ignition and the key was still on, luckily when the car stopped the cars behind me stopped.I was then able to turn the key again, and the truck turned on...this has happened one other time but don't remember the date exactly... I also had the water pump replaced after being told by the dealer that it was ok...I am looking to get refunded for that repair...bulletin no. 13079.

Have had two incidents where the stability track has come on and had to pull over and turn vehicle off wait 10 minutes and restart and finally it goes off. The last incident was I was driving the light comes on saying engine power reducing and it drops speed down to where I have to pull over not to get hit. I pull over turn the truck off and it starts but reduces power again and turns itself off this happens about three times before I give up. I then have to call a tow truck when they arrive and tries to start it does start now. I have been having this vehicle for 6 months.
