Chevrolet and GMC trucks recalled for transmission control valve failure

General Motors is recalling certain 2020-2022 trucks and SUVs with diesel engines because the transmission control valve may fail, causing rear wheels to lock up and increasing crash risk.

What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: Rear wheel lock-up from transmission control valve failure is a structural vehicle defect that directly increases crash risk. Per the severity rubric, structural vehicle defects warrant a Severe rating.

Plain-English summary

General Motors is recalling 463,295 vehicles across multiple model lines from 2020-2022, including Chevrolet Silverado (1500, 2500, 3500), GMC Sierra (1500, 2500, 3500), Cadillac Escalade and Escalade ESV, Chevrolet Tahoe and Suburban, and GMC Yukon and Yukon XL.

The transmission control valve in these vehicles may fail, causing the rear wheels to lock up. This significantly increases the risk of a crash.
