The 2025 Gmc Sierra 2500 carries 1 open NHTSA recall — most recently covering pressure monitoring and regulating systems. Owners report 4 recurring issue clusters, led by “Transmission fluid, shifting, and lockup faults.” GMC trucks and SUVs use the GM Oil Life System (OLS) — the same algorithm as Chevrolet. Because GMC's lineup is exclusively trucks and SUVs, severe-service intervals apply to most owners (towing, hauling, off-roading). The schedule below surfaces the items most relevant to GMC's truck-focused buyer.

TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS

Campaign #26V530000 · Aug 13, 2026

Issue: General Motors, LLC (GM) is recalling certain 2024-2025 Chevrolet Silverado 2500 and GMC Sierra 2500 vehicles equipped with the enhanced towing option and 20-inch accessory tire/wheel package. The tire information label may state the incorrect rear tire pressure, resulting in underinflated tires and preventing the tire pressure monitoring system (TPMS) from displaying a low tire pressure warning.

Risk: Driving with underinflated tires can increase the risk of a crash.

Fix: Dealers will inspect, update the engine control module (ECM) software, apply a tire label overlay, inflate tires to the correct pressure, and perform a tire pressure monitor system (TPMS) re-learn process as necessary, free of charge. Owner notification letters are expected to be mailed September 28, 2026. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N262561970. Vehicle Identification Numbers (VIN) involved in this recall became searchable on NHTSA.gov on August 13, 2026.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)

No occupant deaths in FARS 2010–2024 crashes are on record for this year and model. That is the census answer for the window, and it says nothing more than that.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
