CHEVROLET Complaints

The contact's son owns a 2020 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle made an abnormal rattling sound, and the check engine warning light was illuminated. The vehicle was initially taken to an independent mechanic who could not perform the repair. The contact was referred to another independent mechanic, where it was diagnosed that a crack in the catalytic converter had caused a defect within the exhaust manifold. The contact was then informed that the failure was related to Technical Service Bulletin Number: PIP5681C and was referred to the dealer for assistance. The contact had taken the vehicle to the dealer, where the contact was informed that the vehicle no longer qualified for the TSB repair due to the mileage. The manufacturer was notified of the failure and made the same assessment. The contact was then referred to the NHTSA Hotline for assistance. The vehicle had yet to be repaired. The failure mileage was approximately 90,100.

I was in an accident that resulted in being hit on the passenger side and then colliding with a traffic light pole. My concern is I hit the pole head on and my airbags never deployed

Car is cutting off while driving , I’m driving on a busy road , engine jerks and stall out leaving me with no power to accelerate. Brakes work but gas pedal not so much . I have to cut off the car hoping it turns on , cause it don’t want to turn over once I decide to turn it off

Had to have all lifters replaced even after its a known issue with the manufacturer i had to pay out of pocket with no recall

Shift to park message when car is in park - cannot turn off vehicle until message goes away. Car can roll if message is not off. Brakes: intense squeaking

The radio system working with the phone produces a high pitch static noise when trying to make a phone call or when receiving a phone call. This has been reported to the dealership.Mechanics say that chevrolet does not android phones, only iphones and this is causing the problem with the radio system, the Lights will go on and off at a moment's notice whether you're driving when you're driving radio plays when it wants to play like I said you can't receive Or make phone calls in this car, you have to be outside of the car with the car switched off in order to make a phone call, driving down the road in the middle of the night the lights could just go out sometimes for a whole 10 minutes before they come on again, radio does the same thing in and out in and out at anytime, it does not care Is there a fix for these problems. Dealership did not note this problem said it was not a fix and phone needed to be changed, so there is no documentation of the incidence as they happen. Dealership refused to do the paperwork refused to check, it said it was normal because of that Android phone. Chevy does not support an Android phone on their vehicles.

While driving on the interstate vehicle begin to surge and lag with a check engine light appearing. Vehicle never became disabled but after reading it sounds like this a very known issue with Trax’s. Chevy app stated it was the emissions control system which is most common for purge valve failure. GM needs to issue a recall as the purges valve in every Trax is defective just like the did with earlier models.

Around April of 2025, I noticed loud engine noises and cold start loud noises coming from the engine. My car has been in the shop multiple times since then and I opened a case with GM about multiple repair issues with my 2014 Chevy Sonic LT even though I take excellent care of the vehicle and perform all maintenance on the vehicle, and now this loud engine noise issue and leaking oil. I was driving home from a relative's home Saturday night Dec 27th late evening on the expressway when I noticed my car driving very sluggish and jerking and make extremely loud engine noises and continued burning oil smell in the cabin of the vehicle. No check engine light or oil light, now I had stopped by the service department earlier in the week when and oil pressure light came on, and they stated no issues. I made it home without incident, but the car was not running right. The car was brought to the dealership service department Monday Dec 29th, and they informed me they found broken plastic pieces of guard rails that secure the timing chains in the engine which may have caused serious damage to the engine. The dealership wanted 4k dollars to repair it after they could not properly diagnose a known online issue that I found out a lot of these Chevy drivers have found out about and having me repair other items on the car instead of fixing the leaking oil problem and whatever was going on in the engine. The manufacturer has not inspected this issue now only the service department at the local Chevy dealership has, however I had a case open with GM before this final incident occurred on Nov 1st after my last repair and complaint to the dealership about loud engine noises. GM would not take my concerns seriously and stated we are sorry, but your car is out of warranty even though this is a known issue of this plastic guard rail failing and other serious engine issues with Chevy. I would like the NHTSA to be involved in this matter and investigate this matter if possible.

Vacuum pump busted as shown in photos. Once that busted it sent metal shrapnel into the engine which broke a piece of the cam shaft into bits. There were metal fragments that had to be meticulously cleaned out of my engine block. The loss of vacuum seal caused me to lose brakes while driving in stop and go traffic on the highway.

BCM failure causing the oil pressure to fall to zero and making the car unusable. It also stated the mileage on the odometer does not match the mileage on the BCM.
