NHTSA's VIN data lists these trims for the 2024 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 374 complaints with NHTSA about the 2024 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 4 recall campaigns for the 2024 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.
General Motors LLC (GM) is recalling certain 2021-2024 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with a 6.2L V8 gas engine. The connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure.
Risk: Engine failure increases the risk of a crash.
Remedy: Dealers will inspect the engine, and as necessary, repair or replace the engine. For vehicles that pass inspection, dealers will add higher viscosity oil, install 6 oil fill cap, replace the oil filter, and update the owner's manual. Repairs will be performed free of charge. Owner notification letters were mailed June 18, 2025. Owners may contact Cadillac customer service at 1-800-333-4223, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is N252494000.
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.
General Motors, LLC (GM) is recalling certain 2024 GMC Sierra EV vehicles. The front turn signal lights and parking lights may be too similar in brightness, making it difficult to see the front turn signals when they are activated. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: Front turn signals that are difficult to see may not clearly indicate the driver's intentions to other road users, increasing the risk of a crash.
Remedy: Dealers will replace the headlamp multipurpose LED driver (MLD) module, free of charge. Owner notification letters were mailed November 4, 2024. Owners may contact GMC customer service at 888-988-7267. GM's number for this recall is N242474560.
General Motors, LLC (GM) is recalling certain 2024 Cadillac Lyriq, Chevrolet Blazer EV, Chevrolet Silverado EV, GMC Hummer EV SUV, and GMC Sierra EV vehicles. The electric motors in the rear drive units may have insufficiently insulated wires that can contact each other, resulting in a loss of drive power.
Risk: A loss of drive power increases the risk of a crash.
Remedy: Dealers will replace the rear drive unit, free of charge. Owner notification letters were mailed May 16, 2024. Owners may contact Chevrolet customer service at 1-800-222-1020; Cadillac customer service at 1-800-458-8006; Hummer customer service at 1-800-732-5493; or GMC customer service at 1-800-462-8782.

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.
The owner's manual gives the oil and how often to change it. We show oil facts only once we've checked them against the manual, and we haven't yet for the 2024 Sierra.
These are searches on those sites; we don't copy or check their listings. Your ZIP is used for these links and never kept.
