Owner report 11163190 · 2018-12-23 (December 23, 2018)
THE BRAKE PEDAL IS TOO CLOSE TO THE DRIVER IN RELATION TO THE GAS PEDAL. THE DISTANCE OF EACH PEDAL CANNOT BE ADJUSTED INDEPENDENTLY. A DRIVER'S FOOT CAN BE TRAPPED IN BETWEEN THE TWO PEDALS BECAUSE OF THE GAP. IN A FATAL SITUATION, IT TAKES LONGER FOR THE RIGHT FOOT TO MOVE FROM THE GAS PEDAL TO THE BRAKE PEDAL SINCE THE RIGHT FOOT CANNOT JUST MOVE LATERALLY TO THE LEFT, BUT IT NEEDS TO GO AROUND.

Transmission issues on 2018 Chevy Tahoe. The vehicle stopped on the Hwy. Dealership says the transmission needs to be replaced. Is uncertain why the transmission has gone out on the vehicle since it’s only 4 years old. Error message came on my vehicle and I called the dealership. From my research it appears Chevrolet is continuing to have problems with the transmission on its Tahoes. This is unexceptionable. The consumer has to pay the price not the manufacturer. Please assist.

Owner report 11489374 · 2022-10-15 (October 15, 2022)
A lifter collapsed, which in turn damaged the lobes of a piston, which then damaged the camshaft...generating a repair bill of $7,100 per the dealer. The vehicle only has 69,200 miles on it. When the lifter failed, the car shuddered at stops, lost some power and made a noticeable clanking noise. When pulling out from stops, or into traffic, the car hesitated somewhat before accelerating. This creates a very dangerous situation. Also, if more lifters or the camshaft seized up at higher speeds, a driver could experience a potentially fatal s…
