2020 GMC Sierra: Recalls and Reported Problems
Every NHTSA safety recall recorded for this model year, what owners report most often, and how to check whether one specific vehicle still has open work.
Two identical Sierras can differ entirely: one may have had every recall repaired, the other none.
NHTSA lists 12 safety recalls for the 2020 GMC Sierra, alongside 460 owner complaints filed with the agency, most often about engine. Recall repairs are performed free of charge by a franchised dealer, with no expiry on safety recalls. A recall applies to a production range, so check the specific VIN — a previous owner may already have had the work done.

Recall campaigns for the 2020 GMC Sierra

NHTSA records 12 campaigns in total for this model year; the 8 most recent are listed above. Run the VIN through NHTSA’s free lookup for the complete, vehicle-specific list.
How to check one specific Sierra
- Copy the 17-character VIN from the windshield or driver-door label — not from the listing.
- Run it through NHTSA’s free recall lookup to see open campaigns for that exact vehicle.
- Ask the seller for repair documentation on any campaign that shows as completed.
- Check title, odometer, and total-loss history separately; recalls say nothing about a vehicle’s past.
- Book an independent pre-purchase inspection focused on the systems owners report most.
What this data cannot tell you
- Whether a specific vehicle is included in a campaign, or whether its recall work was completed — only a VIN lookup answers that.
- Whether a complaint is accurate. NHTSA publishes owner reports without verifying them.
- How reliable the model is overall: complaint volume tracks how many vehicles were sold as much as how they hold up.
- Anything about title brands, accident history, odometer records, or liens on an individual vehicle.
