NHTSA Questions GM’s Sierra Grille Fix After 21 Trucks Lose Deflectors Post-Repair

NHTSA’s Office of Defects Investigation opened recall query RQ26003 on October 9, 2026, covering an estimated 535,639 GMC Sierra 1500 pickups from the 2022 through 2024 model years. The subject is the upper grille deflector — the wide trim bar across the top of the grille — detaching while the truck is moving. ODI counts 118 owner complaints, and 21 of them say the deflector came off after the truck had already received the recall repair.

A recall query is NHTSA’s tool for asking whether a manufacturer’s recall actually worked: did the remedy fix the defect, and did the recall cover the right vehicles? This one challenges both. The original campaign, recall 25V-060 filed February 6, 2025, covered only 70,768 trucks — 2022 Sierra 1500s with a chrome deflector built after the mid-cycle refresh. The new query sweeps in non-chrome 2022 trucks and every 2023 and 2024 Sierra 1500: more than seven times the original population.

The agency’s summary describes the deflector detaching “without detectability,” and lists the people at risk as the truck itself, nearby vehicles, motorcyclists and pedestrians. No crashes, injuries or deaths have been reported so far. GM’s own paper trail shows a slow start: an employee flagged a detached deflector through the company’s internal Speak Up for Safety program on January 19, 2024, GM closed its investigation that May after finding no defect trend, then reopened it in December 2024 as warranty claims climbed.

What it means for owners: if you drive a 2022–2024 Sierra 1500, a flying trim bar at highway speed is a hazard to everyone around you, not just a cosmetic issue. Watch for an expanded recall — 21 post-repair failures is exactly the kind of data that forces one.
