NHTSA Complaint #11430507 — 2016 GMC SIERRA 1500

This complaint follows the same pattern for thousands of vehicles manufactured by General Motors. The specific component is the 8L90 (RPO-5MU) 8-speed transmission. The vehicle has experienced torque converter shudder since the purchase date of 06/28/2016. Numerous "attempts" via TSBs and cover-ups by General Motors has failed to alleviate the common shifting, shuddering, rough shifting, LURCHING out of control along with appurtenant damage to adjacent components and structures within the vehicle itself. The vehicle manufacturer has attempted to forestall remedy at the expense of consumers. It has knowingly violated specific requirements for merchantability of said vehicle. IF SUCH KNOWLEDGE had been in my possession prior to purchase, I would NEVER have purchased the subject vehicle. Damage to torque converter components via polluted fluid and destructive particles caused by torque converter malfunction are situated throughout the entire structure of the named Transmission itself. Valve bodies. Gears. Filters, Fluids and tolerances have all been affected by the KNOWN DEFICIENCY by the stated manufacturer: General Motors Corporation. General Motors has shown neither the desire; nor will, to effect a meaningful and reliable solution to this problem.
