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.

I was driving to work and luckily had already gotten off the freeway, driving aprox. 35mph the vehicle started to loose speed, a couple of msgs were popping up "stabilitrac off" "service stability control" "reduced engine power". the speed dropped down to about 5 mph, I had to pull over in order for the vehicles behind me to pass me. I put the vehicle on park and while idling, it started vibrating. I turned it off and then turn it back on. After this it seemed to be doing good., enough for me to get to work

Driving on the highway in nh in traffic when stabilitrac/reduced power/traction control light came on and car slowed down to 15 mph on a busy highway. Barely made it off the next exit as car wouldn't go over 10 mph. Luckily the cars behind me did not slam into me as it was a dangerous situation. A recall is needed is it is a serious safety issue.

Traverse 6-cyl

I was traveling to work this morning (2/18/15) on a Missouri state highway and suddenly power was reduced dramatically on my 2011 Chevrolet Traverse. I immediately looked at my dic and noticed the following readings listed: "service stable track", "engine power reduced", "traction control off", "service traction control". also, my check engine light came on as well. I was able to pull over to the shoulder of the highway but my maximum speed was only 15 mph. I stopped on the shoulder of the highway and put the vehicle in park and then put back in drive. I went back in to traffic but my maximum speed was only 40 mph. After arriving at my office, I noticed the engine appeared to not being running properly, as if it wasn't getting the right fuel/oxygen mixture. I called the GM dealership to inform them of the problems and took the vehicle to them for testing. They diagnosed the problem as needing to replace the throttle body and the part would not be in until tomorrow. I will be picking the vehicle up tomorrow after the repair and I hope this doesn't happen again because if my wife or son had been driving the vehicle, it may have resulted in an accident on the highway. This is something that should never happen in a vehicle, the chance of an accident on a busy interstate or highway is very likely when your speed in reduced dramatically.

I was driving at approximately 65 mph on a highway when the tcs turned off by itself a message indicator came on stating reduced power tcs off service stabilitrak. I took it to a jack williams since they were the only ones open on at the time. They inspected the car and determined I had a bad battery and replaced it. The tcs started working again and worked until 2/16/15 when again traveling on a highway at 65mph the tcs turned off by itself. I got off the highway shut off the car. A few minutes later I restarted and drove home on a back road. 5 miles from my house the tcs again turned off again. A minute later the engine light came on. I took it to a Chevy dealership at motorworld. They determined that the throttle body was blocked. My choices were to flush the system which they would not guarantee the would fix the problem as they do not take the throttle body itself apart to see if it is serviceable or to replace the throttle body and flush the system. The dealership stated that flushing the system is part of the preventative maintenance and should be done every 40,000 miles. Upon looking in my owners manual I found no requirement that this is a preventative maintenance item. If it was the manufacturer should have listed it in the manual. I researched forums and found that I was not the only person with this issue. This was a severe safety issue as you lose power and drop speed quickly which could have caused an accident. Below is the link to the forum on If Chevy took safety seriously they should have a direct compliant section on their website to complain to so that all cars problems are tracked.

Traverse 6-cyl

  • 66,729 miles
Vehicle had error messages, service traction control, traction control is off, service stabilitrax, engine power is reduced. Vehicle was slow to accelerate and experienced decreased speed. Vehicle vibrating while idling. Was told by dealer not to continue to drive the vehicle because others with same error messages stalled out while driving the vehicle, could not get the car restarted and had to be towed. The sudden slow acceleration and decreased speed are safety issues which need to be addressed by GMC before someone gets killed or seriously injured. Dealership said codes were P2176, P0121 and P0221 all related to tps sensor. Replaced throttle body, total cost $607.42. Not covered under power train warranty or extended warranty. According to a blog, in approximately 2009 GMC stopped covering the throttle body under the power train warranty even though vehicles manufactured after 2009 continue to have the same issues. Additionally, blogs indicate that even when the problem gets fixed by the dealer (at the owner's expense), the same issue tends to arise again. This issue needs to be addressed with a recall by GMC as soon as possible with the owner's duly compensated for any costs they may have incurred.

I was driving and the traction indicator light appeared. A warning showing loss of engine power was displayed and the car slowed to about 15 mph. I had to pull over. I turned the Traverse off, and restarted it. I was able to drive home. The next day, the same thing happened. After restarting the car, I was able to get home. From what I've been reading, this is a very common occurrence for this vehicle. It should be recalled and fixed.

On 2/3/15 driving 60mph on the 1-87 my steering wheel began to vibrate on and off. Then drove about 5 miles further then my stabilitrack and traction control failed with its indication on the dash board then the vehicle skid symbol lit up and the dashboard stated engine loss of power and the vehicle slowing began to decelerate to about 40mph and I had to pull over on the shoulder and had my vehicle towed to Chevy dealer. I was told it was my throttle body. Which I see seems a big problem for a lot of 2011 Traverse owners. The repair will cost me nearly $700 after I replaced a burned out wireharness for $658 just 2 weeks ago!!!!

Stabilitrak and traction control issues. Car reduces acceleration during low and higher speeds of driving. Very dangerous to my family and other drivers on the road to have a reduction in acceleration while traveling during rush hour traffic on a busy highway. I have noticed this has become an issue with many owners of GM vehicles.

When I pulled out of a driveway and began to drive down the street, my Traverse message board read, traction control off, engine power reduced, service stablitrac. I was unable to accelerate past 40 mph. My car was unsteady and shaky. I called GM and they stated that I have recalls issued on the car but none of them have anything to do with my current issue. It seems this is a common problem that GM is not addressing concerning a faulty throttle body. I am very frighten to drive especially of highway and with my children in the car. I bought this vehicle because I believed it would be safe for my family.

Daughter was driving, with kids in car. 6:45 pm 1/25/2015. Traction control warning light came on and acceleration dropped instantly. She pulled over and turned off vehicle. Restarted and still could not get past 45 mph. Pulled over again and turned off for five minutes. When pulled back onto highway was able to proceed normally, edmunds forum and chevytraverse forums stated this has happened repeatedly.

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.

The contact owns a 2011 Chevrolet Traverse. The contact stated while driving 60 mph, the electronic stability control, traction control and the engine power reduced warning lights illuminated on the instrumental panel. The vehicle independently reduced power. The contact merged to the side of the road where the vehicle was turn off and restarted however, the warning indicator remained illuminated. The dealer was made contacted. The manufacturer was not made aware of the failure. The vehicle was not diagnosed. The failure mileage was 82,000.

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!

As I was driving, I received three messages on my vehicle: Service traction control, service stabilitrak and engine running at reduced power. Took the car to my local mechanic and they flushed out something (I don't remember what exactly). It ran fine for a few weeks then as I was on the freeway the same messages appeared and as I was trying to accelerate up a slight incline, the car's speed was decreasing even though I was pushing on the gas. Luckily I was in the right lane and there was light traffic or there could have been a major accident as I could not increase speed. Took the car to the dealership who says I need the throttle body replaced and it will cost $600. After looking at this site, I see there are many, many complaints for the same issue. This should definitely be a safety recall!

I was driving on the highway in the fast lane and all of a sudden an error message started flashing. It stated that I needed to have my stability track serviced. About 2 seconds later it say that power would be reduced to my engine and then my vehicle slowed down immediately from about 65 mph to about 15 mph. I had to cross 3 lanes of traffic to get to the shoulder. I was horrified and prayed and thanked god that we were not killed. I had my daughter in the vehicle with me. We had to wait on the highway for a tow truck to tow us through the fort mchenry tunnel to safety. This apparently is a problem with this vehicle. Why haven't a recall been issued. Someone is going to die if this problem isn't fixed.

I was driving along at 65 mph when the "stabiltrak off" light came on followed by the "traction control" light and the "engine power reduced" light. My Traverse slowed down to 15 mph on a busy interstate. I was very lucky to be able to get over to the side of the road. After reading the owners manual I shut the car off for about a minute, re-started it and everything seemed fine. The next day it started doing it again and now shutting it down and restarting it may or may not fix it. Taking it to the shop today but see alot of people having the same problem and it seems to re-occur frequently. Definitely seems like a recall item as it can create a very dangerous situation when the power is automatically reduced. Especially on a busy highway.

Driving on the road and all of a sudden the dashboard lights up. The car tells me that the "stabilitrack needs to be serviced" and "reducing speed". the car just slows down and I can't go above 15 mph in the middle of the road with cars all around me driving at the same speed. Thank god I was able to pull over to the right and get off the road. I shut car off and waited a few minutes. I turned car on and the system reset itself and car was fine. Now its doing it again as my wife drove it today. Researching online, I see many people are having this same problem. GM needs to recall these vehicles and fix this problem. Someone is going to get killed in an accident!
