When driving at low speeds or cornering at steep angles the traction control activates and will almost stop the vehicle. Previously had issue repaired under warranty and they replaced a wiring harness. Issue occurred again. A dealer service tech informed me that there is an issue with water getting in the harnesses but there is no recall only a technical service bulletin. Where it is a known issue that effects the traction control and ABS I feel this being a know issue should be addressed though a recall as the repair is expensive and a safety concern.

- Belle Glade, FL, USA

Blind side motion detector monitoring system malfunctioned. This was after headlight malfunction so we thought it was related to headlight repair. Dealer said no. Car was in motion when warning light came on. Classic Chevrolet/GM refused to cover under manufacturer's warranty even though it's under 36,000 miles. They said it was because we were 2 months after warranty. Contacted Chevrolet/GM hoping for partial coverage to no avail. System should not have failed that soon. Neighbor said his system failed also. It was still under warranty so that means his didn't even make it past 36 months.

It's shutting off while driving.

- Norman, OK, USA

I leased the car brand new in October 2014 and my passenger headlight burned out. I took it to the dealership to have it replaced and found out that it will cost $350 to replace the bulb (the warranty was for 3 years or 36K miles, I have 41K miles on it). However, the light bulbs should last longer than 2 years on a brand new car. I called GM and they said they could do nothing.

While traveling 70mph, all electrical controls inside the vehicle turned off, including the headlights. They immediately came back on, but did not register that the vehicle was in gear (the speedometer was registering 0 but the car was still traveling). The next morning the car would not turn on immediately (it took several tries) and then when we reached the mechanic, it would not turn off. We have been having issues with the electrical components for some time. The mirror sensor (with blind spot indicator) went out soon after purchase. The front camera will sporadically stop working with an error light. Traction control will turn off, with an error message. This car has some serious electrical issues.

While driving and accelerating to get on the highway the electronic stability control "stabilitract" light popped up on the dash screen and reduced the engine's power, reducing my speed to a maximum of 30 mph when trying to accelerate to the posted 55 mph speed limit. I was traveling in a straight line when the "stabilitract" & "engine power being reduced" information popped up. The car would not go over 30 mph. This caused me to have to pull over and nearly caused an accident due to the slow nature of the vehicle, even with the emergency flashers on. This is several incidents with this particular car, having electronic failure. The worst of it was when the collision sensor was affected by a leak in the car after having to have the windshield replaced due to the rear view mirror falling off. That incident caused the car to slam on it's breaks due an electrical error. This car has been in the shop for numerous electrical issues. Chevrolet has refused to do anything but the bare minimum to get the car back on the road obviously not fixing the root of the problem, as this is once again an electrical issue. Not safe to drive if the electronics are going to continue to fail.

Water was leaking down from over head dome light and from door jam, all the main electrical safety controls are housed where the light is in the roof. Called dealership was told first available date to get the car in for repairs is February 22nd. On my drive home from work the collision control came on started flashing the red lights on the dash and slammed on the brakes, like the was a vehicle in front of me has come to a dead stop, except there was no vehicle in front of me, the road was open. I was getting off the highway when this occurred, while driving in a straight line. When home and the car was turned off I'm getting errors saying key fob isn't in the car, and the electronic parking brake needs to be serviced. The car is inoperable at this point. Even if it does start again is a safety hazard at best and has to be towed to the dealership for repairs. It cannot be driven in the electrical state it's in.

2014 Chevrolet Impala requesting reimbursement or replacement vehicle. The consumer stated the nearest dealer was 40 miles away. The consumer stated it was the 4th recall notice, he received.

- Foristell, MO, USA

The vehicle is equipped with a vehicle collision warning device that is intended to warn the driver of a vehicle in front that you are to close to and closing range without braking. On about 1/2 dozen occasions the vehicle's early detection system has engaged without any vehicles in front. These occurrences seem to be on days when it is raining and their are reflections off the road, or very sunny days (again causing reflections). The flashing light, loud alarm, and interruption with regular audio is very jarring (scary). On one occasion I applied my brakes very hard because of the alarm (but there was no car in front) - this almost caused the car behind to hit me. The system should be disengaged to prevent a false/positive alarm. I have taken it for service and contacted General Motors without results.
