Complaint Summary
POWER TRAIN
Owner Narrative
2021 Chevy Suburban started to have harsh shifting particularly on acceleration and shuddering at higher rates of speed (feeling like you are driving over a rumble strip). I took it to the dealer, and they confirmed the torque converter was in the process of failing. It's currently in the shop getting a new torque converter. No warning messages/lights had yet appeared. Technician at dealer stated that this was a common failure with this model.
