Hyundai Tucson brake control unit can corrode and cause fire

NHTSA campaign 20V543000 · Reported 2020-09-04 · Hyundai Motor America

critical How serious is it? About this label

Very serious: an engine compartment fire can injure people or lead to a crash, so park outside and away from buildings until it is repaired, though the notice does not tell you to stop driving.

⚠ Park outside, away from buildings — fire risk. See all such recalls.

What's wrong, in plain English

The control box for the anti-lock brakes sits in the engine bay and can rust inside. That can cause an electrical short and start a fire under the hood. Dealers will replace a fuse in that control box at no charge, and on 2019-2021 models they will also update the stability control software. Hyundai first announced this recall in September 2020 and added more Tucsons, going back to 2016, that December.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to see if your Tucson is covered. 2. Park outside and away from structures as a precaution. 3. Call your Hyundai dealer or Hyundai at 1-855-371-9460 (recall 195) for the free fuse replacement and, if applicable, the software update.
