Stalling on other Malibu years

Report counts are for each model year on its own, so a newer car has had less time to collect them.

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 15 service bulletins or notices for the 2020 Chevrolet Malibu 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

“My vehicle displays a "shift to park" message on the dashboard, even when the gear selector is in the park position. This prevents the car from being shut off, and in sometimes, the doors may not be able to be locked. Not understanding the issue initially has thus caused me to have to replace my car battery numerous times for battery drainage.”

“The steering assist is reduced will come on. The car randomly turns itself off and back on when at a stoplight; this has happened four times now. I worry that it will shut off and not restart creating a hazard on the road.”

Filed Nov 10, 2023

“The power train may be defective. The auto shut off on the vehicle completely shuts off when you stopped at a red light. The entire vehicle restarts, and then 12 lights appear on the dashboard. The car starts shaking sometimes when it's being driven. The vehicle is currently being looked at, at the dealership. I was told that the diagnostics is reading 19 codes and misfires.”

Filed Oct 13, 2023

“While driving on expressway, vehicle slows down suddenly. Service ESC, power steering, and engine light comes on and car tuns off. This has happened 8 times in two years with no fix from GM. This happens with no warning the car just stops driving and loss of power steering occurs. The dealership has tried to fix 8 times now with no real fix to the issue.”

Should you keep driving it?

This page can't tell you that. 0 of 38 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.
