- The defect
- General Motors, LLC (GM) is recalling certain 2019-2020 Chevrolet 6500HD vehicles. The engine control module (ECM) was calibrated incorrectly, allowing the vehicle to exceed the tires' maximum speed rating of 75 mph.
- What it can cause
- Tire failure can occur if the vehicle speed exceeds the maximum tire speed rating, increasing the risk of a crash.
- What the dealer does
- Dealers will update the ECM software, free of charge. Owner notification letters were mailed June 7, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N202325530.
- NHTSA's note
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

How this campaign compares
At 196 vehicles this is a small campaign: 61% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published are as large or larger. The middle campaign on file covers 472. It covers model years 2019 to 2020, so the oldest vehicles on it were 2 model years old when the defect was reported to NHTSA.
Chevrolet vehicles have been recalled over the engine and engine cooling 13 times before this, most recently in December 2016 as 16V868000. That is not evidence the earlier repair failed.
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by General Motors, LLC with NHTSA on May 13, 2021 as campaign 21V346000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
