Purchased a year ago in FL. My windshield came loose twice already where you can see the padding in the dashboard area again. The tire on driver side has to have air in it several times after driving about 20 mins. Pressure keeps reading at 26 and alarm going off with the problem. Husband refills and three days later I move the vehicle and it happens again. Windshield you can hear air leaking from it. Several times when I started my car it had a weird engine noise loud acceleration even when sitting in my driveway. I read no recalls but possible class action pending if you refuse to fix the vehicles. I will be over 36 months before my car reaches 30k miles. I drive to and from doctors, grocery shopping. Casual driving.
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.
