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.

What got replaced

Owners who name the part that was replaced mention the battery (16 reports) and the throttle body (4 reports).

Is this a known problem?

The manufacturer has sent NHTSA 7 service bulletins or notices for the 2018 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

“Cam-driven Brake Booster Vacuum failure without warning. My engine died, my brake pedal and steering wheel stiffened, while in moderate traffic. I had use excessive brake force to slow my vehicle to a stop. Currently have 78,012 miles as it is sitting in the repairs shop. This is the first time it has happened, but I worry it may happen again because upon further research, it is a very common part failure.”

“Getting an error "shift to park" message when parking and trying to shut the vehicle off. Have to now apply the parking brake, shift into gear, and shift back to park to get the vehicle to register in that it is in park to shut off. This error does not allow vehicles to be shut off or even doors locked which could pose a risk of a small child getting into the vehicle in these hot temperatures.”

“Warning: Reduced speed, car stalled in the middle of traffic. Took to dealer ship and they charged me $279 and said it was the battery, from the looks of everyone else’s complaint, which we have the same complaint, I got ripped off. I deserve a refund and we all deserve our cars serviced.”

Should you keep driving it?

This page can't tell you that. 3 of 122 reports involved a crash and 3 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.
