2020 Chevrolet Colorado Complaints

Vehicle has 54,250 miles. Vehicle has a rear differential bearing going out by hearing and feeling the grinding at all speeds and the transmission jerks shafting gears. Both could cause an accident if totally fail. Chevrolet has a service bulletin out from what my local garage says. Mechanic also says Chevrolet will not warranty the product. Vehicle is now being looked at by a Chevrolet dealer. The vehicle is OUT OF WARRANTY. My son, who is [XXX] and not familiar with vehicles thought it was the tires causing the whining and vibration. Took the vehicle in several times to Chevy and they ignored the issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle experienced a sudden and progressive transmission failure during normal driving conditions. Symptoms included harsh shifting, delayed engagement, loss of power transfer, and eventual inability to reliably propel the vehicle. The failure created a safety risk due to unexpected loss of acceleration and unpredictable drivetrain behavior while in traffic. The transmission issue was not the result of improper maintenance. The vehicle was maintained according to manufacturer recommendations. The condition worsened over time and ultimately required dealer inspection. A dealership inspected the vehicle and attributed the failure to a transmission defect, characterizing it as a maintenance issue despite no evidence of neglect. The transmission and related components remain available for inspection upon request. No warning lights provided adequate advance notice prior to the functional failure. The issue occurred without driver misuse and under ordinary driving conditions.

The contact owns a 2020 Chevrolet Colorado. The contact stated that while accelerating, the vehicle vibrated and shook abnormally, as if driven over ripples on the roadway. No warning lights were illuminated. The vehicle was taken to the dealer, and the tires were balanced. The contact picked up the vehicle and stated that the failure persisted. The vehicle was taken back to the dealer, where it was diagnosed that the transmission oil failed to heat up as intended, and condensation had built up in the transmission. The dealer added Mobil 1 transmission oil to heat up the oil and remove the condensation. The contact was informed by the dealer that the vehicle needed to be driven between 200 and 400 miles to remove the condensation. The manufacturer was made aware of the failure and filed a claim and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 80,000.
