2022 GMC Canyon Engine problems

address a known thermostat issue affecting certain vehicles. The program provides extended coverage for the engine coolant thermostat and its housing for up to 15 years or 150,000 miles from the vehicle's original in-service date, subject to the program's eligibility requirements. The issue I experienced is consistent with the condition addressed by this program. The P0128 diagnostic trouble code indicates that the engine coolant temperature is not reaching the expected operating temperature within the specified time, which can be caused by a malfunctioning thermostat. This is the type of failure that the special coverage program was established to address. Unfortunately, I incurred the expense of repairing this condition out of pocket. Had I been aware of the applicable special coverage at the time of the repair, I would have sought assistance through an authorized Chevrolet/GMC dealership before paying for the repair myself. I respectfully request that General Motors review my repair documentation and consider reimbursing me for the costs incurred. The existence of Special Coverage Program Bulletin #N242484760 demonstrates that GM has recognized this thermostat issue and established extended coverage for eligible vehicles experiencing the condition. I believe it is reasonable and fair for GM to review my claim in light of the nature of the defect, the diagnostic code involved, and the purpose of the special coverage program.
