NHTSA Complaint #11668734 — 2023 GMC SIERRA 1500

The original engine in my 2023 GMC Sierra 1500 (6.2L L87) failed in November 2023 at only 2,872 miles. The dealership diagnosed engine knocking and discovered a damaged thrust bearing and crankshaft with metal debris throughout. The engine was replaced under warranty. In April 2025, GM issued Safety Recall N252494001 for the same engine model due to connecting rod and/or crankshaft manufacturing defects. According to GM’s bulletin, engine failure can result in sudden loss of propulsion and increase the risk of a crash. Despite already experiencing this failure and being within the affected model year and engine range, I have been told the recall remedy is not available to me because the campaign applies only to dealer inventory vehicles, and my recall status remains "Recall Incomplete: Remedy Not Yet Available." I requested a safety inspection of the replacement engine, but GM has refused, citing the incomplete status. When I escalated to GMC Customer Care, I was told they could not confirm whether my truck is safe or unsafe to drive. This is after already being stranded once with a family vehicle that cost nearly $80,000. I frequently drive with my family and feel I am being left at risk. GM appears to be prioritizing unsold vehicles while leaving current owners without support or assurance. The current engine has not yet failed, but I have no confidence it is safe, especially as it may include the same defective components described in the recall.
