While driving down the street pulling a trailer the engine stopped. I was able to get it to the side of the road. I called the GMC dealer and they dispatched a wrecker. No prior warnings, just a check engine light right before it failed and lost momentum. This is the second of three new trucks from GMC with engine failure, 1st was lifters, and the other two were bearing locked up. All maintenance was performed by the Dealership on all three trucks

Truck did not stop when applying brakes. Message displayed brake system failure and the breaks were spongy. The truck was towed to the dealer and required the master cylinder, gasket, and reservoir to be replaced with 23,403 miles. This appears to be an ongoing issue with GMC Sierra trucks and needs further investigation as this potential could be catastrophic. Also, as this appears to be an ongoing issue, owners should not be responsible for the cost associated with any repairs and should require an immediate recall.

I request that GM and NHTSA investigate whether recall N242490120 / NHTSA recall 25V060 was properly performed and effective, determine why the deflector detached, and assess whether improper installation, defective parts, inadequate fastening, impact, road debris, or another cause was responsible. Evidence and Records Requested Please review or provide: • Complete recall-repair records, including repair orders, technician notes, procedures, parts and fastening specifications, photographs, repair date and mileage, personnel identities, and attachment-point inspections. • An explanation for the discrepancy between the April 18, 2025 myGMC date and April 28, 2025 GM VIN-lookup date. • Dealership inspection findings, photographs, measurements, and conclusions. • GM repair instructions, technical guidance, recall-validation records, and engineering analyses. • A written determination of the probable cause and whether this was a remedy failure, improper installation, defective part, unrelated damage, or unresolved cause. • Criteria for determining whether the grille must be replaced or repaired. • Warranty, goodwill, claim, technical-assistance, and customer-service records. • Similar complaints, warranty claims, field reports, damage reports, and recurrence data. Corrective Actions Requested I request that GM identify the cause, determine whether the grille must be replaced, and assess whether the attachment can be repaired. If the incident resulted from the recall condition, repair, improper installation, defective parts, or failure of the remedy, I request no-cost repair or reimbursement, including grille replacement. If GM attributes the incident to unrelated damage or an external event, I request the supporting evidence and technical basis. I request that NHTSA determine whether additional oversight or corrective action is warranted to prevent recurrence and road-debris hazards.
