2014 Chevrolet Malibu LS ECO , has a start/stop system that will shut off the engine at a traffic light or stop sign upon reaching a full stop and when the brake pedal is firmly pressed. Upon releasing the brake pedal the engine should immediately restart and driver can proceed. Randomly and intermittently the engine will fail to restart, recently it occurred while in heavy traffic with many traffic lights. Problem not noticeable in rural driving. Have not contacted a dealer, no recall found for my VIN. No Check engine light or MIL is illuminated. Can be unnerving when it happens, people are beeping their horns behind me while I have to shift into park, turn off ignition and restart. Engine restarts normally. 2014 model appears to not have a method of disabling this feature. Car has approximately 111,000 miles on it. Problem first occurred last year 1 or 2 times.

Automatic Start/Stop feature is faulty! When it activates, it prevents the engine from restarting for several minutes. This puts myself and others in my car at a major risk of getting in an accident. I have so far been lucky and avoided any accidents. Several thousand has ben spent to try and fix the issue, with no luck.

I have a 2014 Malibu with 87,450 miles. It has worked perfectly up until 6 months ago. It started stalling in traffic intersections and at stop signs, which is a dangerous safety issue. The Auto Stop would engage and then when I put my foot on the accelerator, it stalled out. I would turn the vehicle off and restart it. I took it to countless mechanics who could not figure out what was causing the problem because the Check Engine light did not come on and no codes were triggered. The problem became worse over time and once the vehicle stalled, it would not immediately restart. I took it to my Chevy Dealer and they were baffled as well. They uploaded new software which included the Auto Stop feature, but it continued to stall. They replaced the front battery and checked the one in the trunk. It still stalled. The Dealer said that since the Check Engine light did not come on, they were shooting in the dark. I asked them to disconnect the Auto Stop function, but they said that they couldn't. Unlike other models, there was no disconnection method. I have looked at many on-line chats on the 2014 Chevy Malibu and this defect in the Auto Stop function seems pretty prevalent. No one has come up with a workable solution. I filed a Notice of Claim with Chevrolet corporate and asked them to provide a fix. Does anyone have any ideas of either how to fix the Auto Stop or to disable it? Right now I am shifting into neutral at all traffic signals and stop signs, so that the Auto Stop function does not engage, but that seems like a poor fix to the problem.

6 months ago our car’s auto stop/start feature started to malfunction. The car will stall and sputter on the start after coming to a stop. This is very dangerous! On multiple occasions, the car would not accelerate through a turn on a light stalling out in the intersection. we have also been nearly rear-ended at red lights because the vehicle will not accelerate on a green light. This issue is well discussed on the Internet with many owners reporting the same issue. Chevrolet should be held accountable for this repair. This is not an isolated event with my vehicle.

The problem became worse over time and once the vehicle stalled, it would not immediately restart. No one has come up with a workable solution.
