2018 Chevrolet Traverse

The contact owns a 2018 Chevrolet Traverse. The contact stated that when the vehicle started, the engine made an extremely loud sound and smoke came from the exhaust. The contact stated that the vehicle sounded like a motorcycle. While the contact's wife was driving the vehicle, there were fumes from the exhaust entering the cabin of the vehicle. The contact stated that his wife had asthma, and the fumes affected her breathing while driving the vehicle. Additionally, the contact's wife was the main driver of the vehicle. The vehicle was taken to the mechanic where it was diagnosed with a fractured mid-pipe assembly bracket. The contact was informed that the mid-pipe assembly bracket needed to be replaced. The vehicle was not repaired. The contact was advised to take the vehicle to the dealer. The dealer was made aware of the failure. The vehicle was scheduled to be taken to the dealer for diagnostic testing. The manufacturer was made aware of the failure and a case was filed. The contact was informed that the repair was not covered under an undisclosed Technical Service Bulletin. The contact was informed that the vehicle was not associated with the Technical Service Bulletin. The contact was advised to contact the NHTSA Hotline to report the failure.

The gear shifter in my vehicle consistently fails to lock into “Park.” Whenever I place the car in “Park,” a message appears on the dashboard stating, “Shift to Park,” which prevents me from turning off the vehicle. It takes multiple attempts to get the shifter to lock into place and for the message to disappear. This issue is not only frustrating but also poses a potential safety hazard, as the vehicle does not reliably indicate that it is in “Park.”

The issue is with the Traverse Stabilitrak system. The Stabilitrak system controls, includes traction control, emergency brakes, tire monitoring, etc. as I understand it. The Stabilitrak lights has been intermittently coming on for several months. I took the truck to the manufacture and was charged over $1,700.00 to fix the problem. After the repairs, I picked up the vehicle and within three miles of the dealership the issue manifested itself again. The Stabiltrak system light usually indicates as the vehicle waits at a traffic light, and just as I accelerate for the signal change. The vehicle frequently stalls at that point, creating a rear end hazard, and a dangerous situation for me and other commuters. Upon returning the vehicle to the dealership, they claimed not to be able to identify the issue, that they initially charged me over $1,700.00 to fix. The said they could not recreate the problem, although it is a persistent problem that occurs within minutes of the vehicle operation.

After I purchased the vehicle in 2021 I noticed there was a shuddering feeling when accelerating at speeds below 40mph. I found the service bulletin and the dealership flushed the transmission fluid and reprogrammed the transmission. Issue seemed to be resolved, but on 11/4/24 I was pulling my car out of a parking lot after being parked 4 hours and when shifting from park to drive the car lurched forward and made a loud clunking sound. There were no lights on so I drove onto the highway and shortly after the check engine light came on and I could not accelerate above 50 mph. I limped the car to a nearby dealership and they indicated that the transmission was shot and needed to be rebuilt or replaced. It is currently in the shop waiting to be rebuilt. The total cost is around $5,500. Between both transmission incidents I also had an issue with the shift to park and service stabilitrak warning lights. That was fixed before warranty expired, but I am now out of warranty and need to pay out of pocket. Called Chevrolet corporate and was told they'd look into offering financial relief but still haven't heard back from them despite the case being escalated. This is a known issue and is a risk to driver safety. There should be a recall and all expenses should be reimbursed!

Had my traverse for two years, second owner. When I received the car, it had to immediately go into the shop as they couldn’t figure out why all sorts of dash lights where coming on. My car was at the dealership for three weeks and ultimately they replaced the chip, stating that was the issue. Two months down the road, I get the shift to park error message starting. Fast forward to 4 months ago when the stability error message starts to intermittently come on and off. 30 days ago I got the first of the service charging system message and the battery saver mode. My car shut itself down while I was doing 55 miles per hour on a back country road. Every lthing locked up and I had to force a turn to get out of traffic. It was determined my battery was good but alternator was bad. Checked fuses just to be safe all were good. Replaced the alternator with a new one. As of today, I am not able to drive my vehicle because of this same issue. This time I went ahead and replaced the battery and nothing has changed. They are saying it’s my alternator AGAIN. How is this possible that all of us 2018 traverse drivers are experiencing the exact same malfunctions in order and now we have to repeatedly replace the alternator? There is no way 1000s more of traverse owners are all buying “bad” alternators. Something is going on with this and these vehicles are not safe to drive. I can’t even trade mine in because my credit is shot. I pay way too much for this car to not be able to reliably and safely transport my kids to and from school.
