What to do
- Park outside, away from houses, garages and other cars — there is a fire risk even when the vehicle is off.
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2023 SILVERADO 4500.
- Book a repair at any authorized Chevrolet dealer. Quote NHTSA campaign 25V390000 (manufacturer code N242482680).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-866-467-9700.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
