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

critical Park outside 652,024 vehicles affected 96% reported repaired

What was reported

Source: manufacturer filing, 49 CFR Part 573
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. Fix 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.

Reported to NHTSA Sep 4, 2020 by Hyundai Motor America, owners notified Nov 2, 2020.

Read from NHTSA’s copy of the manufacturer’s dealer documents (manufacturer campaign 195). The procedure itself is in the bulletin; a franchised dealer has the current copy on the manufacturer’s portal, and that copy governs. Working a lot or a fleet? Recall Watch carries this line on every VIN it checks: remedy status, hours, stop-sale.

How much of it has been fixed

of the campaign

The final figure: the six quarters of reporting that 49 cfr 573.7 requires have closed.

This is the manufacturer's own cumulative count of vehicles it has inspected and repaired, divided by the vehicles the campaign covers. It files that count with NHTSA every quarter for six consecutive quarters, starting from the quarter in which owners were told a remedy was ready, and then the obligation ends — so a figure on an older campaign is where the count stopped, not where it stands today.

It rarely reaches 100%, and not because the work was not done. The same report asks manufacturers to count vehicles they could not reach at all — exported, stolen, scrapped, or simply never located — and those stay in the denominator. A low number means a lot of these vehicles are still out there unrepaired; it does not tell you which ones.

Common questions

Source: NHTSA, 49 CFR Part 573

What does this advisory mean?

Park outside means the vehicle can catch fire while parked and switched off, so it should be kept away from buildings and other vehicles until the repair is done. These are the two most serious things NHTSA can attach to a campaign, and both mean the risk exists while the vehicle is switched off.

Is 195 the same recall as 20V543000?

Yes. 195 is the number Hyundai Motor America uses for this campaign in its own paperwork and in the letter it sends owners. 20V543000 is the number NHTSA files it under. One recall, two references — dealers and service departments generally quote the manufacturer's.

Does this recall repair cost anything?

No. Federal law requires the manufacturer to remedy a safety defect or a compliance failure at no charge, for vehicles up to 15 years old measured from the date of first sale. A dealer that asks you to pay for a recall repair is in the wrong.

How do I know whether my vehicle is included?

By VIN, not by model year. The manufacturer files a build range with NHTSA and only vehicles inside it are covered, so two identical-looking cars from the same year can differ. NHTSA's own lookup checks a VIN against the manufacturer's list.

What if the repair is not available yet?

It happens, and often. Manufacturers must notify owners when a defect is found even if the parts or the software are not ready, then notify them a second time once the remedy exists. The remedy filed for this campaign is described above.

What did the manufacturer say was wrong?

The problem, risk and fix quoted on this page are the manufacturer's own words as filed with NHTSA under 49 CFR Part 573. WhichTrim does not paraphrase them.

Who started this recall?

NHTSA's record credits NHTSA's Office of Defects Investigation. NHTSA’s investigation file links this recall to preliminary evaluation PE19003. A recall can begin with the manufacturer's own testing, with a defect investigation, or with a compliance test against a Federal Motor Vehicle Safety Standard.
