My Impala 2014 was making a loud noise from, the rear of the vehicle as if it was the muffler. The noise could only be heard while I was inside the vehicle. I had my wife stand outside while I drove the vehicle down our street and the loud noise could not be heard outside of the vehicle. We could hear the noise once the vehicle reached 20 mph. After getting the muffler checked we found out the muffler was in good condition., but shortly after the Impala started making the loud noise we made a left turn at a signal light and the ABS, power steering, and stablitrak service lights came on the dashboard. The power steering has gotten increasingly worse since the service light came on.

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.

Takata recall" when the car starts up and is put into drive, there's a hard grinding noice around front wheels. Once we turn off the traction control it stops and drives fine. If traction control is on you can't turn the car left or right without grinding

Driving under normal highway conditions the power steering suddenly stopped functioning and the "service power steering" "service stabilititrack" message displayed on the dash, ABS, and stabilitrak lights all coming on. Car is starting to become hard to turn. I pulled the vehicle off at the next exit and I called GM roadside assistance and after waiting about 15 minutes I started the car back the power steering failed. This making the vehicle unsafe to drive.

My service side detection system light came on Monday. On Thursday bright sunny day one by one all systems failed. No air bags, no blinkers, no alarms sounding, nothing on dash working, everything is gone except eng is still running.I was driving in milwaukee hwy and city streets. I was 2 hours from home so I drove to the closest dealership. When they tried to access the computer they were locked out. A few hours later they were finally able to access the computer and it told them both side detector modules needed replacing. They were able to get service lights on. We drove home and our local dealer is going to replace the side detection modules. $600 for parts alone. Receipt is only the out of town dealer as parts are not in. Receipt for repair is not attached as it is to be repaired tommorrow. (date on scanning is one day off).... my VIN is not in the side detector recalls

Stabilitrak control system I am contacting you about the safety hazard of the stabilitrak control system malfunctioning on our 2014 Impala lt Chevrolet. On November 7, 2016 I was driving from my home in perfect weather conditions and the car suddenly would not accelerate properly. The vehicle information center read 'service stabilitrak' and 'engine power reduced'. then the check engine light went on. I called GM customer service and the local Chevrolet service center felix Chevrolet to schedule servicing on the vehicle. I assumed the repair had corrected the problem. Then on March 7, 2017 in perfect driving conditions the same thing happened when I was leaving for an appointment. The vehicle information center read 'service stabilitrak' and 'engine power reduced'. then the check engine light went on. I immediately returned home and called GM. The car was towed to felix Chevrolet. The mileage on the car was 13907, less than 159 miles later. The diagnosis this time was the need to replace the acc sensor and the repair was performed. I have asked both the dealership and GM to explain why stabilitrak engages so unexpectedly and my concerns about the safety of driving this vehicle, especially on the freeway with the sudden reduced engine power preventing you from being able to accelerate properly. No one can reassure me that this will not happen again.

When making right or left turns at times you will get a grinding in the front also some hesitation stability light ABS light also the brake assistant warning will flash this is a safety factor that has been bought to Chevy's attention with no results. Safety is priority at least it suppose to me, at the moment it is not chevorlet.

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.

On 12/21/16 while merging onto interstate 10 in tucson, AZ, the vehicle was going approximately 65 mph when a "engine power reduced" sign popped up, the vehicle slowed down to 30 mph without warning and shifting down through all gears nearly red lining the rpms and causing an rear-end collision. Was able to move the vehicle off the freeway and took it into local auto-zone for testing. The test came back as a "throttle sensor malfunction". the vehicle now doesn't feel safe to drive, and will not accelerate over 45 mph without shaking and feeling like the transmission is going to give out. Called the local Chevy dealership and was told the cost was going to vary between $400-1,000 with a $100 test fee up front. I've also read numerous similar issues online from people driving Chevrolet Impala from 2006-2016. The car feel very unsafe to drive and I feel it could be a death trap as there is no control over when the vehicle will choose to decelerate without warning. There has been no mechanical issues before this incident, and the vehicle has been through numerous mechanical maintenance up-keeps that were recommended by service managers.

While turning right and backing up or turning right into a parking space at low speed the stabilitrac/ traction control activates and stops the driver side front wheel for a moment, and then releases and a grinding/rubbing noise is heard coming from the drivers side front wheel when this problem happens and is a random problem that happens more frequently, when it is cold and damp.

- Gladwin, MI, USA

At about 85,000 miles I am getting a grinding noise from the left front side. Dealer said it was bearings, which I had replaced at a private garage. Now the sound is back after only a thousand miles or so. Typically, it happens at low speed, and mostly when turning left.

My Impala 2014 suddenly says 'service stabilitrak' in the display and the engine power drastically reduces. I have see this in forums that is a common issue with GM cars and it happened to me couple of times. This is a very dangerous issue when happens at freeways or any faster traffic routes.

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.
