Defect. General Motors, LLC (GM) is recalling certain 2019-2020 Chevrolet Silverado Medium Duty 4500HD, 5500HD, and 6500HD vehicles.

Owners may contact GM customer assistance number at 1-866-467-9700. GM's number for this recall is N252531990. Vehicles in this recall were previously repaired under 25V390 and will need to have the new remedy completed. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov beginning November 6, 2025.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
