What’s wrong with it?
An engine compartment fire can increase the risk of injury or crash.
Hyundai Motor America (Hyundai) recalled certain 2019-2021 Tucson vehicles on September 4, 2020.
On December 30, 2020, Hyundai expanded the recall population, and added certain 2016-2018 Tucson vehicles.
The Anti-lock Brake Hydraulic Electronic Control Unit (HECU) could corrode internally and cause an electrical short, possibly resulting in an engine compartment fire.
