Park outside — fire risk

Problem: 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.

Risk: An engine compartment fire can increase the risk of injury or crash.

Remedy: Hyundai will notify owners, and dealers will replace the HECU fuse. For 2019-2021 model years, the Electronic Stability Control (ESC) software will also be updated. Recall repairs will be performed free of charge. Owners are advised to park outside and away from structures as a precaution until the recall repair is complete. The recall began November 2, 2020. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 195.

Service brakes · Nov 2025 · NHTSA complaint record

We were driving and the engine light started flashing and buckling. The vehicle had been properly maintained with oil changes. We have oil changes receipts from our mechanic.

Engine started making a knocking sound, then the oil light came on followed by the check engine light. Accelerates and decelerates on its own.
