Stalling on other Tucson years

Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2020, 2021, 2023, 2024, 2025, 2026.

What this problem usually is

Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.

Is this a known problem?

The manufacturer has sent NHTSA 2 service bulletins or notices for the 2018 Hyundai Tucson that deal with this problem. Newest first.

Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote

“The engine on this vehicle burns oil quickly which is a known defect. I took the vehicle to the dealership and both times I was told everything was working fine. On 12/5/2025 the vehicle just lost power while driving. After getting the vehicle towed to a mechanic they said I needed a new engine.”

Should you keep driving it?

This page can't tell you that. 2 of 80 reports involved a crash and 2 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
