GMC is recalling 354 units of the 2026 Hummer EV Pickup and SUV after discovering that the front passenger airbag may fail to deploy due to an improperly crimped wire connection inside the instrument-panel harness.
According to a detailed NHTSA filing (Recall No. 25V769), the defect stems from a three-day period in July 2025 when the supplier’s automated crimping equipment was offline for maintenance and the backup manual process produced inconsistent terminal connections. The issue affects vehicles built between July 31 and October 24, 2025, and creates a risk of increased injury in certain frontal crashes.

What the Recall Covers
GMC’s investigation shows that the defective wire harness, built by Yazaki North America, may interfere with the airbag’s ability to receive deployment signals. Although some vehicles produced during the period were corrected before leaving the plant, 245 SUVs and 109 pickups remain at risk. GMC says owners may notice an airbag warning light, but not all vehicles will display one. Dealers will install a jumper harness with properly crimped connectors at no cost, with owner notifications scheduled to begin December 22, 2025.
The recall surfaces at a time when EV truck buyers are already comparing models closely. Even small safety defects can influence purchase decisions in a segment where automakers rely heavily on technology leadership and perceived robustness.

Why GMC Is Taking Action Now
The issue was first flagged on August 21, 2025, when a loose wire was noticed during assembly of a Hummer EV SUV. GM opened a formal investigation days later and traced the problem to a manual crimping procedure used during supplier machine downtime. No field incidents or injuries have been reported, but GM opted to issue a safety recall after confirming inconsistent harness integrity.
The airbag defect also adds to a broader pattern of scrutiny surrounding GM’s safety campaigns. The automaker is already responding to legal pressure over past recalls, including a class-action claim that a previous fix didn’t resolve underlying faults, and a separate lawsuit regarding brake issues in 2025 SUVs and trucks. This latest recall will likely intensify conversations about quality control as GM scales its EV lineup.
What Owners Need to Do
Owners should check their VIN on the NHTSA website or contact GMC support directly to schedule the necessary service appointment.
Until the updated jumper harness is installed, the front passenger airbag may still fail to deploy properly in a crash, creating a clear safety concern. The repair is free of charge, and all affected vehicles remain fully covered under warranty.
