2014 Chevrolet Malibu

I have been an issue with my auto stop system past 6 months. While driving and coming to a complete stop the auto stop kicks into gear as it should but when I release the gas pedal to drive off it stalls for a about 20 seconds unlocking/locking doors and proceeds to kick into drive gear. I have had auxiliary battery checked and it’s good. Checked main battery components those are good too! No check engine light came on only when I removed auxiliary battery removed to have it diagnosed it did give me a code of UO101 but quickly went away when replaced. Still trying to figure what the issue may be but it’s becoming more and more constant and worse. Dangerous when it happens on uphill and cars behind because car rolls backwards almost hitting them.

Was in a bad wreck, other drivers car deployed airbags, mine did not but engine shut off and hazards stayed on. Crash was about 30 miles an hour or so at impact.

Incident Aug 22, 2025

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.

Incident Apr 3, 2025

This is now the THIRD time this has happened, and GM doesn't seem to care, because when my mechanic "fixed" my auto stop problem, it was because GM themselves got the code to "fix" my car. My auto stop worked one time, before today, after my repair last week. I was at a stop light where my auto stop turned on. My brakes WERE STUCK AND COULDN'T BRAKE so I put it in park! THE SAME ISSUE WITH THE WHEEL AND BRAKE LOCKING OCCURRED. GM FIX THIS!

Incident Feb 14, 2025

When the auto stop feature turns on, the car totally stops, and doesn't turn the engine back on for 20 minutes. I had complained about this before, and the mechanic did NOT fix it, so I am complaining AGAIN! I was in the middle of the street when it stalled! The steering wheel and brake locks up, and it's impossible for the engine to turn on. It revs, but doesn't work. THIS NEEDS TO BE ADDRESSED.

Incident Feb 18, 2025

Auto start stop malfunctioning, my safety as well as my children have been in the car when the car has stopped while in the middle of driving. It has stopped in the middle of the road and on the freeway in moving traffic and for 1-3 minutes the car won’t start back up leaving me and my family stranded in the middle of the road where anyone can and have almost hit us. When I’ve sent the car to my dealer mechanic he told me the car cuts off like that because it runs hot when that is not the reason after he told me that he fixed I drove off and it stopped on me as the light was turning green for traffic to go. The car had the issue about 3 days after i purchased it I’ve which was last year 2024 in June and as of now the issue still hasn’t been fixed by the dealer

Incident Feb 13, 2025

When I was on auto stop, my car never started back up. The steering wheel and brakes were frozen, and I could barely pull off the road I was on. Turning the key did not help, as the engine wouldn't turn back on.

Incident Feb 13, 2025

I am uncertain of what’s causing this major issue to happen. I see a lot of forums of other customers having the same exact issue and it is a HUGE SAFETY RISK in my personal opinion from experience. For the last maybe 9 months I’ve been dealing with the auto stop feature coming on, then once you let off the break the car doesn’t crank back up. This is very scary in traffic and stoplights much less everywhere!!! I have to turn the key to off and place it back in park, then proceed to crank back up. Only nearly EVERY SINGLE TIME it also will not crank up manually. Also, this issue is not showing ANY check engine codes, so diagnosing this issue has not been resolved. I’ve been stuck waiting 20 minutes or so. Please PLEASE recall whatever is causing this issue for so many of us customers!!!

Incident Jan 3, 2024

I am filing a complaint regarding a 2014 Chevrolet Malibu that I purchased from a dealership on November 22, 2024. The vehicle was advertised as being in “excellent condition” at the dealership’s site. During the test drive, I raised concerns about potential transmission issues, but the dealership assured me that the vehicle was “clean” and safe to drive. Unfortunately, this assurance turned out to be false, as the vehicle has since displayed significant mechanical failures, including overheating issues, that pose serious safety risks. Within a week of purchase, the vehicle broke down twice: first on November 29, while driving to work, and again on November 30, while on I-10 Katy freeway. The second breakdown created a life-threatening situation as the vehicle suddenly lost power in traffic. I incurred towing costs of $125 to return the vehicle to the dealership. After an attempted repair, the vehicle was returned to me on December 5, 2024. However, it broke down again on December 8, 2024, requiring another tow. Since that time, the vehicle has remained at the dealership, yet no adequate resolution has been provided. Additionally, I have since discovered that the vehicle has persistent overheating issues that were not disclosed at the time of sale. These overheating problems pose a serious safety risk as they could result in a fire or explosion, endangering my life and the lives of others on the road. The dealership’s negligence in addressing these critical safety concerns demonstrates a disregard for consumer safety. I believe the dealership knowingly sold me a defective vehicle with significant mechanical issues that were either hidden or misrepresented. The sudden and repeated breakdowns, particularly in hazardous driving conditions, and the risk of fire or explosion due to overheating, warrant immediate attention from the NHTSA.

Incident Dec 2, 2024

Hello. I have a 2014 Malibu. Recently it has been stalling when coming to a stop and yet there are no engine/warning lights on. Took it to numerous mechanics, spoke with people at the dealership service area and yet nothing! Nobody can figure it out at all. I’ve had the throttle body replaced, module piece, and a few other parts by someone who previously worked at the Chevrolet dealership and even they can’t figure it out. This is not only a safety hazard but a very uncomfortable feeling riding a car and having to put it into Neutral when approaching a light or stop sign ! My car will tell me if my turn signal is on for longer than 2-3 minutes so I’m not understanding why it won’t tell me why my car is shutting off. I’m frustrated because I’m paying different mechanics to figure it out and it’s still an unsolved problem! It would be nice if Chevrolet can look at everyone’s vehicle and not charge this time!! I have children so having them ride in a car that stalls is UNACCEPTABLE!

Incident Sep 4, 2024

The cars automatic start/stop will activate and not restart the car. This has happened at stop signs, stop lights, intersections, hard breaks, etc. There are no warning lights or system failed/malfunction warnings. This has been inspected multiple times with software updates, changing batteries, changing fuses, etc.

Incident May 15, 2024

When coming to a complete stop, the auto stop feature kicks on and then stalls the car and won’t restart. Have seen in many online forms that this is a very common problem with these cars

Incident Jun 9, 2024

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.

Incident Jun 8, 2024

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

Incident May 4, 2024

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 $1,000.00 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.

Incident Mar 11, 2024

The Auto Stop/Start feature is experiencing issues where the vehicle fails to restart, resulting in significant disruptions during driving scenarios such as heavy city traffic, stop-and-go traffic, and maneuvering through busy intersections. These incidents not only cause traffic jams and congestion but also force detours for other drivers. Particularly, when encountering highway traffic from exit offramps, sudden stops due to overcrowding and tailgaters trigger the Malibu to auto stop without restarting, creating considerable challenges, especially during rush hours in cities like Atlanta. In each of these circumstances, attempts to restart the vehicle prove futile as the engine endlessly turns over without success. While resolving these situations required considerable effort and time, further elaboration is beyond the scope of this discussion, given the valuable time already expended on addressing these issues.

Incident Mar 8, 2024

my vehicle had just fixed by chevy dealership they changed both battery. i drove and pick it up,but its having the same problem it stalled or stops in red lights when i push brake it engaged the autop stop and have to restart the car again. almost got into an accident because i was stucked in the traffic with green lights and im in the middle of the road and my gas pedal wont work/accelerate. i paid 700$ for both battery i need my refund too.

Incident Feb 27, 2024

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

Incident Sep 13, 2022

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.

Incident Aug 16, 2023

The car tries to start in its own. Even if the key is on the off-position. The car struts and shocks aren’t the best it won’t take a bump without moving the car

Incident Feb 14, 2024

The defrost control does not engage properly causing very poor visual conditions. Has been this way for a long time now and have not been able to get it fixed. If this problem does not get fixed soon I feel it will cause an accident. Thank you for your time.

Incident Jul 15, 2021

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.
