Stalling on other Elantra 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: 2021, 2022.

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.

What got replaced

Recalls and investigations

One recall on the engine covers the 2020 model year. A recall on the same system isn't always the same failure, so read the defect text.

The piston oil rings may not have been properly heat-treated, which could result in engine damage.

Is this a known problem?

The manufacturer has sent NHTSA 1 service bulletin or notice for the 2020 Hyundai Elantra 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

“At 105,000 MI. My car stalled out and the engine stopped. It needs a new cam shaft, timing chain set, cam phaser and timing cover. We also had to replace the Variable valve timing solenoids as the metal melted.”

“Engine is stalling and consuming oil at a higher then normal rate. Knock sensor is having issues at 24k miles both part of recall campaign 974 and recall 203. Took the auto to dealer for service and was told Hyundai would not honor the recall due to a branded title which now puts me in a scenario of possibly engine stall in the middle of highway traffic.”

Should you keep driving it?

This page can't tell you that. 0 of 37 reports involved a crash. 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.
