CHEVROLET Complaints

The vehicle has blown 3 motors in 3 years. I took felivery 3/17/23. The first engine blew at 8,000 miles on 10/27/24. The second one blew 8/29/25 The 3rd one blew 4/12/26 at 52,000 miles on the vehicle.

Was parking into a handicap space and all of a sudden the car accelerated by itself

The fuel pump quit while driving, fortunately we were not on as interstate highway. I was able to coast to the side of the road and call for tow. If this occurred on an interstate highway it could have been very dangerous. The dealer repaired the vehicle under a warranty. The fuel pump and control module were replaced.

Original 6.2L engine was replaced subsequent to NHTSA Report 11724274 from Catatrophic engine failure on January 31, 2026 at 25,274 miles. Original engine was manufactured on May 30, 2024, but Silverado HC was manufactured on June 9, 2024, so it was not captured in existing NHTSA Campaign 25V-274 and subsequent GM 6.2L Recall and is not currently included in expanded factory 10/150,000 powertrain warranty. Due to original catastrophic engine failure due to crank and connecting rod, covered transmission damage was discovered, truck is currently on third Torque Converter and Transmission has been out of truck for repairs to Valve Body and 4-10/reverse piston twice. Replacement 6.2L engine lasted 3,900 miles before exhibiting significant Lifter Tick Bank One/Driver Side, Tear down revealed failed lifter which wiped out a lobe on Cam. GM TAC refused engine replacement, instead replaced one Cam, 16 lifters and trays on Bank One. Drove truck for approximately 300 miles after repair and Engine began exhibiting significant knocking from bottom of engine, second replacement engine is now being installed. All routine maintenance and Warranty work has been performed and documented at GM certified Dealer Service Department.

from a stop during fast acceleration made a left turn and rear section or rear axle sounded like it went over a speed bump or wheels locked up, then transmission felt like it was in high gear, did not want to move , or very slowly , i accelerated rpm was 2k or 3k still moving very slowly, this was in heavy traffic. I notice that check engine light went on with TC, parking brake service , some pad lock ( dont know what the ped lock is). 2nd time this happen the parking light service light went on and the brakes locked up again in traffic. 0

Hard/Erratic shifting and feels like you’re driving over rumble strips. The day I purchased the car.

During an accident when impacted in the front of vehicle not a single airbag deployed

Car recently started to jolt when accelerating. Noticed it firsthand on the highway while on stop and go traffic. It's been doing it more often now when driving around the city. As soon as you accelerate past 15mph, it starts to jolt. The check engine light is not on. I do see that other 2018 Chevy Traverse have a recall, but my car (when checking by VIN) is not included.

the vehicle will not register that it is in park, when the engine is turned off a beeping noise reads shift to park - you have to start the engine and shut it off multiple times, or slam the shifter into place to get it register in park. this happens constantly and is starting to get old, and annoying. it is listed as a known problem on the forum group. when the notice to shift into Park is stuck on, the beeping will not stop... Also there is a shudder while driving no matter the speed. They did a transmission service and messed with torque converters but has not done anything. Also will be driving down the road with cruise control and the cruise control with randomly jerk and shut off for no reason. Has happened on the interstate.

My engine has been replaced twice already for total failure first time was in November 2023 and the second time was May 2026.
