Deaths

A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA has not crash tested the 2026 GMC Sierra 3500. Its New Car Assessment Program tests a selection of each year's vehicles and does not reach motorcycles, heavy trucks, motorhomes or most low-volume models, so an absence here says nothing about how the vehicle would perform. It is not a low score.

What owners have reported about this vehicle is below, and it is a different question: a crash test measures what happens to the people inside in a controlled impact, while a complaint records what broke during ordinary use.

Owners may contact GMC customer service at 1-800-462-8782 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N262544420.

Complaints on file, same model year.

Every GMC on this site — 150 vehicles.

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
