What owners say
The contact's wife owns a 2020 GMC Yukon. The contact stated the vehicle was taken to an independent mechanic for a tune up. The contact stated that upon picking up the vehicle and driving, the transmission was slipping in and out of gear. Additionally, the contact stated while at a complete stop and depressing the accelerator pedal, the engine revved; however, the vehicle hesitated to respond, and the vehicle jerked while responding. The contact stated that the vehicle slowly picked up speed, and the transmission was slipping in and out of gear. There was no warning light illuminated. The contact stated that his wife had noticed that the vehicle made an abnormal sound while driving. The vehicle was taken to the dealer, where it was diagnosed that the torque converter had failed. The dealer determined that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 107,267.
Vehicle started jumping and switched into 4WD while reversing. There was no inclement weather or slipping to prompt this. Service 4WD warning had been showing intermittently for a week or two and service appointment had been scheduled. At service appointment, confirmed that 4WD switch was faulty and needed to be replaced.
Transmission slipping and damage
The transmission is out. Prior to it going out, I experienced loss of power, gear slipping, shuttering and not being able to go among other things. This is very dangerous and can cause serious accidents to occur. This should not be happening on such an expensive and newer vehicle.
