Gateway system module failed during the L87 recall service.The major L87 recall (ECM update) is a major, high-load software update that frequently causes the Gateway Module to "brick" or stop communicating during the update process resulting in failed module immediately following the service. (TSB) speak to this, The L87 recall is a safety-critical repair, a failure of a module directly caused by this repair should be covered under a recall warranty or GM warranty. Safety can be affected as warning lights will not work due to this failure. Timeline of events. As soon as warranty service was completed before leaving bay lights were not working like Onstar etc, app wouldnt connect to car, 1-2 hours after leaving service engine light came on in car. Never had an engine light on before. Took back to dealer who said it was a computer issue they corrected it. 2 hours later engine light was back on. My car has been at the dealer since Monday when they called to say the GSM had internal failure and wanted to charge me to replace it despite this internal failure being in response to the warranty service that was provided, There are Technical service bulletins about this issue, this has been a known issue with GM vehicles, My timeline shows strong evidence that the failure is a direct result of the recall repair. There is GM TechLink documentation that these modules can be ruined if the update process creates a high load. GM needs to extend the GSM repair/recall or extend coverage for this repair when this happens. This is just another thing GM is not taking responsibility for.

On January 24, 2026, my wife was driving the vehicle we purchased in May 2025 from Ziegler GMC in Lincolnwood, Illinois. While traveling on the highway in WI the vehicle suddenly lost power without warning. She was traveling with our [XXX] son at the time and was able to safely maneuver the vehicle off the highway onto an exit ramp. Despite multiple attempts, the vehicle would not restart. She contacted me and arranged for a tow. We waited approximately four hours for roadside assistance before the vehicle was towed to the nearest GMC dealership, located roughly one mile from where the breakdown occurred. Several days later, the dealership completed diagnostics and informed us that the engine required full replacement. At that time, no replacement vehicle was provided. Approximately one week later, we were finally issued a loaner vehicle. As of today, the vehicle has remained in the shop continuously since January 24. On February 23, we were informed that the necessary parts had only just arrived. There is still no estimated completion date for the repair. The vehicle is covered under both the manufacturer’s warranty and an extended warranty. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle: GMC Yukon Denali Model Year: (insert) Engine: 6.2L L87 Mileage at Failure: 44,000 Failure Date: February 18, 2026 Recall: GM 6.2L Engine Failure Recall (crankshaft/bearing defect leading to propulsion loss) Complaint Summary: Complete engine failure and total loss of propulsion on a high-speed highway on-ramp with my family inside, causing extreme danger and emotional trauma. Full Description: On February 18, 2026, my GMC Yukon Denali experienced a sudden and complete loss of propulsion while we were on the on-ramp to a high-speed, heavy-traffic expressway. The engine failed without warning as traffic was accelerating rapidly around us. My husband, my [XXX] son, and I were all in the vehicle on our way to celebrate my son’s birthday. Instead, the vehicle died in one of the most dangerous locations possible — the merge zone of a busy highway — leaving us stranded with cars coming at full speed. Traffic immediately began backing up for a long stretch behind us. Drivers were honking, yelling, and aggressively swerving because the lane was blocked by our stalled vehicle. The situation felt chaotic and frightening. I genuinely believed we were at risk of being rear-ended at highway speed. We felt helpless waiting for police to arrive to protect us. The emotional distress, panic, and fear for my family’s safety were overwhelming. My son was shaking and visibly upset on what was supposed to be his birthday celebration. None of us felt safe until law enforcement was able to block traffic. After the incident, the dealership confirmed that the failure was caused by the GM L87 engine defect currently under recall and stated that the engine needed to be completely replaced. This sudden stall created a severe safety hazard that could have easily resulted in a catastrophic crash, injury, or worse. It has had a lasting emotional impact on me and my family.

Engine failure occurred while transferring passengers in a busy road. The vehicle started making noises at first I thought it was a belt that might have been going bad. I looked at all the gages which did not indicate any issues with the battery or oil pressure or any vital issues that might show and merged to the right lane. Less than 2 miles down the road engine shut off and I was able to coast into a parking lot. I took this vehicle as requested for the recall and the only recommendation was to start using OS 0W40 and a new oil cap indicating the required oil type. These vehicles should be pulled off the roads, they create a huge safety hazard on our roads and sooner or later someone is going to get killed.
