2014 Chevrolet Impala Owner Comments

problem #18

  • 93,600 miles


While driving on city streets and the highway, the stablitrax lights come on then service indicators displays: Service stablitrax, front camera, and power steering. The car slows down significantly and the power steering then locks up until you dismiss all of the codes. Then you can hear a clicking that sounds like the car is trying to restart. It happens sporadically. I took it to a shop and he stated to check for recalls because there have been quite a few Impala being brought in for the same reason. I contacted Chevy and they stated that there are no known recalls for my make and model.

Stabilitrack has been messing up since I purchased this vehicle in October 2018. My car is scary to drive. Sometimes its not clear what gear I'm in. The car will not go over 5 miles per hour when the stabilitrack is messing up. The backup camera does not work when the stabilitrack light is on and sometimes it will not go in reverse. I have to wait and keep turning the car off then wait then try to start it. Stabilitrack needs a recall. I could not back out of my parking spot this morning because of the stabilitrack. It feels like the whole motor moved when I tried to reverse. There were no lights on the panel to know what gear I was in but it wad clear it skipped the reverse. When it finaly let me back up after turning the car on and off several times I could only eccelerate 3 miles per hour.

The cruise control button sticks, when being pushed it clicks hard to get to work. The most important started a couple of weeks ago with the steering wheel on moving and pushing the gas makes a clunky and grinding sound and feel, the vehicle does not go anywhere then, the stability light comes on. The car starts moving, and the wheel frees up and the light goes out. This is every time IżM turning left after from a stopped position.

While driving at any speed the instrument cluster will completely die out. Blinkers not functioning. Seems like some sort of short. Also blind spot alert not working, forward facing camera, park assist.

Blind spot detection system began to fail, indicated by the side mirror indicators remaining on even after the car was shut off. Dealer service center diagnostic test showed the battery was old. The problem progressed to the point where the instrument cluster would also fail - all instruments (speedometer, tachometer, etc.) would go dead, virtually all warning lights (traction control, ABS, air bag, etc.) would go on, heating system (including blower) would go dead and turn signals and hazard light would be inoperative. All of this would happen while driving, whether in city traffic or at highway speeds. Although the main operation of the vehicle has not yet been affected, there is no way to signal other drivers of a problem (no hazard light or turn signals) in the event of a larger failure. Research of online customer forums shows that this problem is common with the latest generation (2014 and newer) Impala. The blind spot detection system is connected to the instrument cluster and this occurs randomly while driving.

While driving on a rural road approaching a sharp curve my vehicle's control panel began to display service power steering drive with care and service stabilitrack messages respectively; immediately thereafter I began to experience difficulty with steering.

  • 62,200 miles
Today is the second time in 6 months that my car has done this. 2014 Chevy Impala 62,000 miles, 4 cylinder. I was driving on the highway at 65 miles an hour and first the "service stabilitrak" warning comes up. Then the "engine power reduced" warning appears. The engine will not go above 20 mph at this point. This is very dangerous especially if you are on the highway at speeds of 65 and suddenly you have no power! I took it to my mechanic who could find nothing wrong with the car. He told me to pull over and shut the car off and restart it. I did that and the check engine light is on but I did get my engine power back. I'm terrified driving this car. Someone is going to get killed in this situation. I read all over the internet about this same problem and nothing is being done about it. This should be a recall!

  • 65,000 miles
Driving to work and all the emergency lights on my dashboard came on for no reason. The speedometer, tachometer, gas gauge, temperature gauge, radio and heater/ac controls and turn signals quit working. Additional warning lights on dashboard we're stabiltrac, ABS, air bag, tire monitor and brake light. Previous to this we had problems with the blind spot monitor system not functioning. The car has been at the dealership now for about 5 weeks with no answer. They currently have 3 other Impala with the same problem. We live in a town of under 10,000 people so what are the odds that we are the only ones. Sorry I do not have access to my VIN number at this time.

Impala 4-cyl

  • 50,000 miles


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.

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.

  • 10,000 miles
When decelerating at a red light which turned green, attempted to accelerate with no throttle response, even when pushed to the floor for approximately 2 seconds or more (several similar incidents). Second incident, car stalled at a slow speed. Third incident, after accelerating the engine rpms stay reving high after taking foot off the gas for several seconds, and this has happened on several occasions and as recently as 9-16-15. These incidents all occured before and after a complete GM dealer reprogrammed the computer.

  • miles
On a couple of different occasions I have been stopped at a stoplight or stop sign. When the gas pedal is pressed to accelerate, there is hesitation by the vehicle to accelerate causing the vehicle's act of acceleration to occur separately from the act of pressing the gas pedal.

  • 300 miles
Forward collision avoidance system inappropriate activation on several occasions at different locations. There were no other vehicle in front. There were three beeps/red light flash on windshield. The cruise control would deactivate and car would decelerate by three to five mile. The tail lamps are not activated to warn drivers following. This is my second complaint the dealer solution is to turn off the feature. It work when it should the inappropriate activation is a nuisance.

Impala 6-cyl

  • 11,250 miles
While driving on Texas highway 287, southbound, my anti-collision alert system activated. It sounded a loud beeping, followed by a full application of all brakes. Startled, I was able to apply the accelerator pedal to resume my speed. Approximately 5 miles further, the incident repeated it self. During the first incident, there were no vehicles in front of me, none. The road was dry, straight and free of any obstacles. There was no traffic behind me. The second time the car automatically locked up my brakes, there was a car behind me, but he was able to swerve and avoid rear-ending me. Again, there was no traffic of any type ahead of me and the road was flat, dry and straight. Again I was able to apply the accelerator pedal to regain control of the car and pull over to the side where I.shut off the engine. I restarted the engine and proceeded to my destination in springtown, Texas without further incident. I took the car to the dealership the next week for a diagnostic search and repair of the incident. They had the car for three days and told me nothing was wrong with the car. I'm filing this complaint, because I believe that this is a potential deadly threat to me, my passengers, or other drivers.
