* Initial Transmission Failure: -In February 2025 my vehicle began experiencing severe and rough shifting, which was quickly followed by a "Check Engine" light. I immediately took the vehicle to dealer for inspection. * Dealer Diagnosis and Repair: -The dealership diagnosed the issue as a worn-out transmission solenoid and valve body. They informed me that they had to install a newly redesigned valve body and replace the solenoid. The repair was completed at my expense, and I paid approximately [$3000]. The dealership had my car for over six weeks, during which I was not provided a courtesy vehicle. As a result, I incurred thousands of dollars in rental car fees. * Denied Reimbursement Claim: -The recall notice included information about reimbursement for out-of-pocket expenses. I was told by the dealership's service advisor that I would receive a reimbursement form, which I did. I meticulously filled out the form and submitted it with all the required documentation, including my repair invoice and proof of payment. The dealership rejected my claim, stating that my specific repair was not covered by the recall and that the recall was only for a software update. This is demonstrably false, as the recall notice itself links the software issue to premature component wear, exactly what I experienced. * Ongoing Safety Concerns: -To make matters worse, I am now experiencing new transmission issues, including slipping, just months after the "repair." I am terrified to take the vehicle back to the dealership, knowing I may have to pay thousands more for rental cars and another repair that may not even solve the problem. I am concerned for my safety and the safety of others on the road, as a failing transmission can pose a serious hazard. I am requesting that the NHTSA investigate this matter. It appears that GM and its dealerships are misleading consumers and failing to honor their responsibility to reimburse owners for expenses directly caused by a known defect.
