I purchased a 2019 Chevy Traverse brand new off the lot as single owner and kept up with maintenance. The transmission just went out while I was on the highway and abruptly begin reducing speed and I was unable to accelerate. This was dangerous as no warning lights came on prior to this happening to warn that there were any engine issues. This could have caused an accident on the highway due to me not having control to accelerate and vehicle de-accelerated without warning. Also the passenger seat belt stop working and would not click. There was a Shift to Park warning that kept coming up on the car about 1.5 years ago that should be a recall as the car would not go off when turned off. The radio and lights in the vehicle would continue to run while the engine was off. I am concerned about all of the issue with this car that makes me question the quality and build of this vehicle. The first 4 years this vehicle was great and then all of a sudden it begin to breakdown in parts. The dealership confirmed all of these things and I asked if warranties were on these items and it was not.

The transmission system on my 2025 Chevrolet Traverse began showing signs of failure approximately 2–3 months after purchase. Symptoms include erratic shifting, gear hesitation, and sporadic power loss while driving. Although the issue was promptly reported to Chevrolet headquarters, I was unable to bring the vehicle to the dealer earlier due to the lack of available loaner vehicles. The car is now at the dealership and has been there for nearly three weeks without any updates or contact from the service team. The transmission is available for inspection, and documentation of the issue exists. The malfunction has created safety risks during normal driving, including delayed acceleration when merging into traffic and unexpected gear disengagement at speed. These conditions compromise vehicle control and increase the likelihood of a collision. Additionally, the vehicle produces a persistent squeaky noise from the accelerator pedal during operation, which could indicate underlying mechanical stress or a deeper linkage issue. The sound is both distracting and concerning, especially during highway driving or sudden acceleration attempts.

Upon slowly pulling into a parking spot my foot was on the brake bringing the vehicle to a stop when the rpms suddenly went up and the vehicle lunged forward striking the stone wall in front of me. The impact caused both my knees to make contact with the steering column. There were no warning lights. The airbag did not deploy and the onstar did not activate although the impact was substantial. I explained this both to the dealer and the insurance company. I was told a gm engineer would need to investigate this issue. I have found numerous accounts of this online.

2018 chevy traverse when decelerating around speeds under 35mph city driving the vehicle will randomly rev up and the RPM will go up to 4000 or 5000 RPM, this also happens while braking. Sometimes the car will jerk forward as if it was going to accelerate and other times it just stays at a high RPM for 5 seconds or less until I either come to a complete stop or try to accelerate and it does not respond. The engine sounds like it is in neutral and the accelerator is being held down. It also does not respond to the gas pedal when it is reving like this, and if I try to accelerate the car will eventually kick into gear and lunge forward. Took it to the dealer withing the first few months of owning it and they could not replicate the issue and said the computer did not return any issue. This problem comes and goes since I bought the car brand new in 2018 and concerns me, because it feels as if the car is accelerating on its own and may cause me to crash.
