2020 Chevrolet Colorado Complaints

Transmission shuttering mostly at interstate speeds but as slow as 35 mph. Under light to medium light pedal acceleration. Truck feels as if it's going over Road ripples. I'm disappointed to find out this is a common problem with Chevy 8-speed Transmissions. It happens every time I drive it. From time to time it'll shake the truck a little violently

The component that failed is the camshaft position actuator. My check engine light came on. Had my vvt solenoids replaced and the mechanic told me the actuator needs replacing. GM has issued a special bulletin to fix this part for the same year make and model as my truck but my vin doesn’t meet the criteria. I have only owned this vehicle for 8 months.

This vehicle suffers from a torque converter/transmission shudder after the transfer mission fluid heats up. My initial complaint to the selling dealer and they did not follow the GM posted procedure and initially charged me for the service. I’ve changed dealerships and I’ve been told it the temporary fix is to do a flush and there is no permanent fix by GM. I have had situations where and unexperienced driver would have definitely got into a car accident and I don’t let anybody drive my car because I believe it is unsafe. So far the dealer has been accommodating while under warranty but advised I reach out to GM who then advised to review my documents I file an NHTSA complaint. What occurs when the vehicle is not in warranty and the vehicle continues to shudder. I have included the service bulletin and repair invoices.

Unknown. When my truck reaches a certain speed it is jumping or missing, it feels like a brake is sticking but I’m told it is a problem with my transmission, torque converter, going bad. It is getting worse. It cuts the power down on the vehicle. If I can go faster than 60 it doesn’t do it.

Vehicle began exhibiting an intermittent shake between 45-60 MPH which felt like driving on a wash board road. In addition it would shift hard/bog down between 1st and 2nd gear. Took to a dealer for service and was told a TSB had been issued to flush the transmission, this was performed. Condition returned within months and after multiple additional visits where the dealer claimed they couldn't replicate the issue they finally determined the torque converter needed to be replaced at approximately 70,874 miles. By this time the warranty had expired (60,000 mile warranty) and I was told I would have to pay for it.
