Selected complaints filed with NHTSA by 2012 Chevrolet Traverse owners, lightly cleaned up (personal details are redacted by NHTSA).
UNKNOWN, I first bought my Chevy Traverse Ltz in April of 2020, and about 2 weeks of driving it, I noticed that all(4)of my wheels/brakes instantly locked up while driving in traffic, almost causing a pile-up collision. The rotors and brakes releases alot of smoke as the wheels scrub and the suv doesn't move forward nor backward. I reported it to the car lot/dealership where i purchased it from and was told to take it to a certain auto shop. I arrived there, just to be told that he doesn't fix those type of problems. The dealership where i bought it from didn't look at it either. So, from that time til now in 2021, I have been dealing with the same exact problems being terrified with my children in the car, not knowing if/when the next time the wheels lock up for no reason, if it will be fatal for me and my children or other drivers. …
It sways left to right really bad.. but when it rains or even even the car detected that it's going to rain.. as soon as the car senses it is going to rain u can't even drive it.. it like hydro plains even before it starts to officially rain.. very dangerous plus I had to replace the two back tires because they seemed like they were being forced and drug that all u seen was wires coming out of the tread
Traveling at 70 MPH on a highway Traction control/stabilitrac and engine turn on and acceleration stopped, car wont accelerate causing to cars behind me to start swirling around due to my car lost of acceleration, then pulled over to the shoulder thankfully with no accidents, then turn off car and turn on again and car worked normally for about 100 miles and it did it again.
The head front left head light has had to be replaced 3 times in 3 months same for the left turn signal. Another issue I have is each time I put gas in, the car gets stuck trying to turn over Until I pump the gas.
First I already had to rebuild the transmission which is showing the beginning signs of failing again. Then around the same time I started having another issue that I find a lot scarier as the driver. It started giving me severely Reduced engine power, traction control off and stabilitrak messages with the ABS warning light lit up like a Christmas tree. This is by far the most dangerous of any issue I've ever experienced with all of my vehicles I've ever owned. It starts with a huge jump I cant stop or control to a car behind me it seems like I'm really getting on it and speeding up. But in a split second too quick for any human to process what is happening it just drops out big time. It then wont go above roughly 30 mph and the engine is revving very high to even get it to that. …
1)The air conditioning unit line has caused a leak. It was determined this line needs to be replaced by an independent service center. This a/c line is located from under the front of the hood all the way to the rear of vehicle. This line constantly rubs and there is friction with other lines/hoses (power steering), and other components under the hood. No rubbing should occur. The rubbing and friction cause holes to form causing not only for it to leak out but also potentially leak on other components under the hood which could cause other issues such as breakdown of the vehicle or fire. It has affected us not only by not providing a/c under extreme heat, but also has caused hissing sounds and for white smoke vapors that has omitted from the vents inside the vehicle. It has also caused us to breathe in the vapors which are toxic. …
When driving the vehicle it will lose power and flash service stabilitrack and low engine mode enabled without warning. This has happened many times since 2016. When the conditions cannot be replicated gm/chevrolet has not been concerned but to refer to dealership. The dealership replaced ECM due to warranty conditions. Issue with emissions and electrical modules continued to cause intermittent power loss. Corrosion was found in the internal fuse box due to poor sun roof drainage emptying into glovebox and onto internal fuse box. GM and Chevrolet describes this as a known issue but insists my VIN is not affected. The issues continued to persist leading to frequent battery replacement that was ultimately due to contamination of electrical components. …
White smoke was coming out the car and my car eventually sat on fire. I had to call the fire department.. fire department stated that it was a electrical issue
I have had many ongoing issues since car purchase. Electrical , air conditioning and injector issues. Car does not seem safe. Lights go out every few months whilde driving when it is dark. This is very dangerous. 1st replacement on light was done while under warrant, however, Chevy dealer failed to address the issues causing the light to burn out and simply changed light out. It has been continuous with us changing lights, brake lights and headlights. Car would lose power and jerk as well as had gears problems while traveling on a fwy with cars going an average og 60 MPH. Car would not auto shift above 20-30 MPH. Gas smell upon start of vehicle and the list goes on. Stuck open EVAP purge solenoid setting ses light cac case 8-2106770252 dalila lopez--- scanned ECM found code p0300 p0496.performed diagnosis. …
While driving the vehicle will shudder and lose power, occasionally the vehicle will stall almost like it is attempting to grab gears while down shifting and it will cause the whole vehicle to shake, it has happened so hard I have had to exit the interstate for worry of mine and my passengers safety. The vehicle upon entering will slam into gear and when driving in rural areas the transmission even feels like it is slipping and the car will jerk back and fourth until it grabs a higher gear. I purchased the vehicle in 2018 with just over 100,000 miles and even now the vehicle is only sitting at roughly 132,000 miles and has has regular services to maintain the vehicle. Upon further investigation, the Traverse has several complaints of this same issue including older and newer vehicles, and most have resulted in torque converter/transmission replacement. …
