Details
What's wrong: The engine control module (ECM) was calibrated incorrectly, allowing the vehicle to exceed the tires' maximum speed rating of 75 mph.
Why it matters: Tire failure can occur if the vehicle speed exceeds the maximum tire speed rating, increasing the risk of a crash.
The fix: Dealers will update the ECM software, free of charge. Owner notification letters were mailed June 7, 2021.
