NHTSA's VIN data lists these trims for the 2025 Sierra. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 128 complaints with NHTSA about the 2025 Sierra. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2025 Sierra over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Rollx Vans (Rollx) is recalling certain GMC Yukon, Sierra, Chevrolet Express 2500, Ford Transit, E-250, Toyota Sienna, Sienna Hybrid, Honda Odyssey, Chrysler Town and Country, Voyager, Pacifica, Dodge Grand Caravan, and Ram Promaster vehicles equipped with QRT-Deluxe and QRT-Max wheelchair restraints. Please refer to Rollx's recall report for specific model year information. The retractors may not lock, preventing the wheelchair from being properly secured.
Risk: An unsecured wheelchair can move during transit, increasing the risk of injury.
Remedy: Rollx will work with Q'Straint to inspect and replace the retractors as necessary, free of charge. Owner notification letters were mailed February 5, 2026. Owners may contact Rollx's customer service at 1-800-956-6668.
General Motors, LLC (GM) is recalling certain 2024 Chevrolet Silverado EV and 2024-2025 GMC Sierra EV pickup trucks. The bolt that secures the rear center seat belt assembly to the seat structure may not have been properly tightened.
Risk: An improperly secured seat belt assembly may not restrain an occupant as intended, increasing the risk of injury in a crash.
Remedy: GM will tighten the bolt that attaches the center seat belt assembly to the rear seat structure, free of charge. All affected vehicles are still in dealer inventory and, therefore, no owner letters will be mailed. Owners may contact GM customer service at 1-888-988-7267, or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N242489901.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
