Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“It began w/a harsh shift from 2nd to 3rd. It started happening more often, my engine light came on& it began shifting so harsh it would jerk you. Went to my GM dealer & the code was for a throttle body sensor. They replaced the sensors & also found a cracked motor mount. They advised the crack was probably due to the transmission shifting so harsh, also the shifting problem was probably due to the sensor malfunction and the lack of communication from the throttle to the transmission. They replaced the mount & sensors. Charged me $700. …”
