Common questions

Is the GMC Sierra 2500 reliable?

We don't score reliability: NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. What's on file for model years 2010 on: 780 owner complaints, 17 warranty extensions and 92 service campaigns GMC filed, and 36 safety recalls. The model years with the most complaints are 2024 (106), 2015 (89), 2020 (77). Whether a known problem was fixed on one car is what its service records show.

What are the most common problems with the GMC Sierra 2500?

Across every model year since 2010, owners' complaints to NHTSA most often name electrical system (17%), transmission and drivetrain (17%), other or unspecified (14%). GMC has filed 17 warranty extensions covering the Sierra 2500, listed on this page.

Which Sierra 2500 model years have the most complaints?

2024 (106), 2015 (89), 2020 (77). Complaint counts rise with how many were sold and how long they've been on the road, so compare years of the Sierra 2500 with each other rather than with other models.

Has GMC extended the warranty on the Sierra 2500?

Yes: transmission and drivetrain (model years 2020–2022); transmission and drivetrain (model years 2020–2022); electrical system (model years 2017–2024), and 14 more. A dealer does a covered repair for free within the extended time or mileage.

How do I check recalls on a Sierra 2500?

Enter the car's 17-character VIN at nhtsa.gov/recalls. That answers for one vehicle; the 36 recalls listed here are for the model, and each covers only part of it.
