2021 CHEVROLET TRAVERSE Complaints

The alternator is placed right under the fill cap for engine oil. So if and when an auto repair shop or owner spills oil out of a funnel or anything else this oil will leak and the first spot it drips onto is the alternator. With all the other plastic under the hood there should be some kind of shield bracket or sloped plastic to get in the way of all the other maintenance under the hood. So precede with caution and avoid the unnecessary cost of an alternator change.

I bought my Chevy traverse car in June 2021 with 0 miles. On 12/25/2023 the alternator went out. I know there any many people who are having this same problem when the car reaches 40k miles. This is not fare to us bc we now have to pay 1700 in repairs. If the alternator goes out when driving, your car will stall and stop and you can end up in a sudden crash. This should not be happening at 40,000 miles.

I was driving on I-20 with cruise control on @ 71 mph (night time) @ 7 min into using cruise control, the suv acted like it stopped for a quick second (scaring me) I remember rubbing my neck afterwards, thinking it was almost like whiplash. I pulled off the road into parking lot. I thought maybe I had a flat or tire issue, no tire issues. I then stopped @ a store, when getting back into the suv, I could smell something awful. Like something had burnt. Still don’t know. I have not used the cruise control since this incident. It was Xmas weekend, so I have to wait till dealer opens back up to have it checked out.

We have had issues with the Onstar system not working after using the key fob to remote start the vehicle. This has been going on for 1.5 years and again GM customer service told me that the engineers are working on it. Additionally the Onstar emergency SOS will not work during this time because it is disabled Red light instead of green. We live in northern Minnesota where the winters can be brutal-20 to -30 degrees and are afraid that the crash detection system will not work due to this issue. Every thing works fine if you start the car with the button on the dashboard. There are numerous complaints about this affecting numerous vehicles including trucks. A real safety hazard being we live and drive in frigid conditions a bunch in the winter. All GM tells me is they are working on it but the Safety bulletin is dated February 2021 and NOTHING HAS BEEN DONE TO CORRECT TIS SAFETY ISSUE!!!!

I was unable to stop my vehicle from accelerating. The brakes were engaging but my vehicle continued to build speed. Myself and my family, as well as others on the road, were all put at risk due to my vehicle not responding or failing to control speed; cruise control was not engaged. My insurance company, USAA, is currently investigating and determining total damage estimate. No warning lamps, indicators, or messages were presented prior to collision. The rotors and brakes were glowing red after collision from continuous attempts to stop the vehicle.

Since I bought this car new the brakes have been squeaking and when I took it to the dealer they said they need about this problem but there was nothing that they could do about it since the manufacture has not given them a bulletin on this model of vehicle yet.

the purge valve is ticking for the past two weeks dealership informed me yesterday that it is working as designed and no codes were noted by technician. ticking noises ( which are VERY annoying) were not present when vehicle was bought about 3 months ago . The service rep informed me that although purge valve issues have been noted and taken care of by other GM models., the traverse is not part of any recall at the moment

KNOWN ISSUE: Chevy Traverse owners may experience a condition wherein the front exhaust pipe on their crossover separates from the mounting bracket, resulting in damage to the pipe. Now, General Motors has issued new Special Coverage that addresses this issue. NEW ISSUE: Rear exhaust pipe is also affected. When separated/cracked this was leaking carbon monoxide fumes into the inside of the vehicle when driven. Our family's safety was put at risk breathing these fumes. The Chevrolet dealership says that only the front exhaust issue is being recalled/covered but rear is not even when it is attached to same mounting bracket with known issue. Appeared/noticed as loud muffler sound and strong smells of fumes.

The contact owns a 2021 Chevrolet Traverse. The contact stated that while operating the vehicle on several occasions, the vehicle shut off and the steering wheel became difficult to turn. Additionally, the interior and exterior lights became inoperable. The vehicle was taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The contact was concerned that the failure was caused by the vehicle being hacked by a local terrorist network. The failure mileage was unknown.

Display Instrument Center on the instrument cluster goes out for a couple of drive cycles and comes back on. I took it in to the dealer at the end of March and had the vehicle updated. There's a history with this issue with the Traverses and the Cadillac XT6. I don't know if it's a glitch when these parts were produced for GM or not but it needs to be investigated
