General Motors has issued a recall for certain examples of the 2019 and 2020 model year Chevy Silverado 6500HD chassis cab truck due to an issue related to the vehicles’ top speed limiter device.
The problem: affected vehicles may have been equipped with a top speed limiter that exceeds the max speed rating of the factory tires. The speed limiter does not allow the truck to exceed 79 mph, however the factory tires only carry a maximum speed rating of 75 mph.
The hazards: if the vehicle speed exceeds the maximum speed rating of the tires, the tire structure will be compromised. This can increase the risk of a tire failure and crash.
The fix: dealers are instructed to update the software calibration for the engine control module to set the speed limiting software so that the vehicle speed will not exceed 75 mph and therefore meet the maximum speed rating of the tires.
Affected components: factory vehicle speed limiter.
