When Stopping/Coming To A Stop. The Auto Start Feature Kicks In And Causes My Locks To Unlock And Lock Back And The Car To Stall For A Second Or

- Chicago Heights, IL, USA

When the Auto Start/Stop engages at a stop sign or light it causes the car to turn off. I have trouble turning it back over. Sometimes it starts. Other times it does not. I have changed the mass airflow sensor, mass air pressure sensor, vvt solenoid. It has been in and out of a couple shops without an answer of why it is doing this. It is readily available for an inspection. There were not any warning lights or messages produced on the dash. This started happening about 3 months ago. My child and myself is in danger every time it dies at a stop light.

Reduced power and coolant system My safety was put a risk when my car stop on me in the middle of traffic

- Elgin, IL, USA

While driving 60 MPH on the highway my car started stuttering then lost all power. It threw 3 codes P0131, P2097 and P0171. I have spent over $1,000 and a month later they tell me it was my intake bolts that were loose. They replaced every part PCV valve, MAF sensor, O2 sensor and car still wouldn't run right. PLEASE address this issue as that is UNSAFE for a car to just stop on the highway.

I bought the car back in 2022 and since then the stop/start started malfunctioning. At first it would stop then be hesitant to start back up then 6 months later it completely would stall at lights and stop signs. Now the aux battery is draining my main battery and I-??ve had to tow my car 3 times because I-??ve been left stranded. I-??m now in that same predicament and it-??s 2/26/24

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.

When I stop my auto stop kicks in and when I take my foot off the brake my car rolls up a little and ends up dying. I have to turn it off and start it up giving it gas to get it going. There have been a couple instances when making a left turn I have almost gotten hit. I am no longer comfortable driving my car. There are several people posting about it online but no reason or fix for it as far as I know of. I have called the dealer and if course they want me to bring it in but I have no money for someone to go on a wild goose chase with my car. I think this should be something Chevrolet needs to figure out.

The automatic start and stop function does not work properly. When the car comes to a stop and auto stops, the vehicle shuts off and does not power up when you hit the gas. My safety is put at risk due to the car shutting off and the possibility of someone hitting me. The vehicle has been inspected countless times. I was told it was an electrical issue. Then told it was the battery. Brand new battery and issue isn-??t fixed. The car cut off once and all the lights came on. Now no lights comes on it just cuts off.

I have researched this problem with compliance with this make and model this seem like an issue that GM should investigate. But I would like to keep driving my vehicle. Who can help me with this problem this is our transportation for now until we can afford another. Thanking you in advance.

The AutoStop/Start feature malfunctioned while at a busy intersection. The AutoStop engaged but failed to start the engine, once pressure was released from the brake pedal. This has been an issue for about a year now. I have replaced both batteries, both VVT sensors, and the oil pressure sensor in the last year, thinking this would solve the issue. This vehicle has not been inspected by a mechanic, just scanned with a handheld scanner at a parts store, every time there is a check engine indicator light on. There are no dash indicators when this malfunctions, I just have to turn the vehicle completely off, or pump the accelerator in order for it to start.

Stop/Start doesn-??t work at least 20% of the time, leaving me stalled in the middle of the road, until *hopefully* it starts again, usually after a few tries.

- Ozark, MO, USA

The vehicles "Auto Off" feature, which shuts the engine off when stopped at red-lights, fails to restart the engine when removing your foot from the brake pedal. The engine stalls out, and much be parked, shut off and then restarted. Sometimes it takes multiple times to restart the vehicle. This is very unsafe considering the car could stall out in an intersection or cause another vehicle to collide with mine if they were behind my vehicle, expecting it to begin moving. I have take my car in for multiple repairs and nobody can figure out the issue.
