The manufacturer was made aware of the failure. The failure mileage was approximately 47,000.
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. …
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. …
I have a 2014 Malibu with 80,000 miles. 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. Engine light comes on, but no code stored. 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. 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 headlights burn out frequently the air conditioner does not work the ignition had to be replaced there's always a code of p0171 the start/stop feature does not work the brakes make the car shake. When does stuff takes place I have to pull the vehicle over cousin me to put others in danger by being on the shoulder of the road broke down. Yes the car is available for inspection. The radio randomly turns on and off therefore the backup camera does not work as it should why this vehicle has not been recalled is beyond me.
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.
On 7/5/20 the vehicle was in motion going down the highway and the high pressure fuel pump mounted on the engine broke lose, dropped into the engine and tore apart the engine. Was towed and fixed by closest GM dealership (deery brothers, west burlington, ia). There is a recall for a bad weld on the high pressure fuel pump for 2016-2018 Malibu's resulting in the exact issue I had on my 2014. The dealership said GM, Chevrolet and the dealership (which is a GM certified dealership where I bought the car certified pre-owned in 2018) said they all bared no responsibility for the issue. I paid $3,128 for the repair on 7/17/20. Two days after bringing my car home, there is an oil leak that was never there before. The dealership says this is a hole in the oil pan, and again is my responsibility to pay for in full to be fixed. …
When start stop was engaged at light the car shut off everything on the dash and radio went blank. It auto started and ac was no longer working. Afterwards I smelled a slight burning scent (in louisiana traffic, I was unsure it was me) but car ran fine. When start stop engaged there was a longer than normal pause before would auto start would engage. It would intermittently fail to crank on occasion for a few key turns. Engine light came on. Trunk would mysteriously pop open. Started displaying two key fobs programmed, ABS stable track, reduced engine power, low battery and another thing I can't remember at start up. I changed the battery and alternator with new ones and the next day the instrument panel flickered as well as head lights. And when I was to take it in to dealership it had complete electrical failure. The dealership said it was the engine fuse block and replaced it. …
The engine light came on with ap2646 code. After attempting to repair, and the code remaining I attempted to find part 12633613. Unable to locate the part I brought it in to a garage. They replaced the same part I had already replaced, and still the engine light remained. They were also unable to locate the referenced part online or through a dealership (mangino Chevrolet). I contacted several dealerships and GM, the party is discontinued and back ordered at parts stores and dealerships. Without this part, the car can not be inspected and becomes a safety issue, and s legal issue of continued to operate on the road (in ny and elsewhere I imagine). The part is faulty on many cars if the back order is an accurate indication. Although it does not prevent safe operation of the car, the car can not be inspected overall for safety until the engine light is fixed.
