GM already fixed this grille once. Twenty-one owners say it came off anyway.
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 Sierra’s grille, coming off while the truck is moving. ODI says it has 118 owner complaints. Twenty-one of them say the deflector came off after the truck had already received the recall repair.
A recall query, not a routine probe
A recall query is NHTSA’s tool for asking whether a manufacturer’s recall worked: whether the remedy fixed the defect and whether the recall covered 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 includes non-chrome 2022 trucks and every 2023 and 2024 Sierra 1500. That’s more than seven times the original population.
ODI’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.
How we got here
GM’s filing for 25V-060 lays out a slow start. A GM employee flagged a deflector that came off a driven 2022 Sierra through the company’s internal Speak Up for Safety program on January 19, 2024. GM opened an investigation on February 27, 2024, then closed it on May 23, 2024, after finding no defect trend. It reopened the issue on December 11, 2024, when warranty claims started climbing.

The mechanism is basic. The deflector is held on by eight attachment points. Those points can crack over time. Once all eight let go, the bar is free to leave at highway speed. GM estimated just 3 percent of the recalled trucks actually had the defect, and its filing notes that drivers may hear a rattle as the deflector starts to come loose.
The fix was modest too. According to the owner letter, dealers would “reinforce or repair” all attachment points on the chrome deflector, in about an hour. GM’s repair instructions have technicians check every retainer and specifically tell them not to replace the front grille unless it’s necessary. So the remedy reinforced the old clips instead of replacing them. Twenty-one post-repair complaints suggest that may not have been enough.
Why a trim piece is a safety issue
On paper, a grille deflector is cosmetic. In practice, it’s a long, rigid piece mounted at bumper-to-windshield height on one of the best-selling full-size trucks in the country. If it lets go at 70 mph, it becomes debris for whoever is following, and the driver most at risk is a motorcyclist.

There’s a liability angle too. Damage to another car from something that falls off your truck generally lands on your own liability coverage first, with any recovery from GM pursued afterward. That’s a strong reason to take a rattling grille seriously now.
What the 2025 recall already set in motion
When GM filed 25V-060, it issued a stop-delivery order covering affected trucks in both new and used dealer inventory, and warned that GM Certified Pre-Owned trucks would lose their certification until repaired. If this query leads to an expanded recall, expect similar sales holds across far more 2022–2024 Sierra inventory.
What owners should do
- Do a walk-around. Push gently on the top grille bar. If it shifts, buzzes or rattles over bumps, get it looked at. Don’t wait for a letter.
- If your truck already had the recall repair, you’re exactly who ODI is asking about. If the deflector loosens or comes off again, file a complaint through NHTSA’s reporting portal. Owner complaints are what opened this query.
- If you own a 2023–2024 or non-chrome 2022 Sierra, you aren’t under any recall yet. A loose deflector is still worth reporting, and keep the receipts if you pay for repairs.
- Used-truck shoppers: run the VIN through NHTSA’s recall lookup, and check the top grille bar for movement before you buy.
A recall query can end in an expanded recall, a revised remedy, or no action at all. GM’s own timeline, with a closed investigation, a reopened one and a fix that some trucks have already outlived, doesn’t buy it much benefit of the doubt.
Sierra owners: has your top grille bar rattled, shifted or come off, and was it before or after the recall repair? That’s exactly what NHTSA is asking.
