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.

I started noticing a very bad odor of mold and mildew coming from the A/C vents. I took the car into the dealer I purchased in early 2014. The dealer said they looked at it and could not find anything wrong. After I took it in again for a bad odor, they said there was a recall on the rear tail lights letting water in the trunk. A couple months later I checked the trunk and the carpet was all wet, when I checked the spare tire compartment it was 2 inches of water. I started checking everywhere and found the carpet in the front driver seat very wet. I took the car in again this time I knew it was going to be a big problem to fix, the car was now smelling so bad with mildew and mold even the service technician could hardly stand to sit in it at all. They have tried to change the underlay, and it still smells bad. The dealer says they had a GM service specialist come to the dealer to look at it. They have no solution to fix the water leaking or to get the mold out of the car. It has now been 6 weeks and I do not have my car!! I asked the dealer to please let me out of my lease so I can go get a car that actually I can use. The dealer is refusing to offer any assistance, and either is GM when I call customer support. I am now hiring an attorney and planning on taking this to the dealer and GM, as this is an major health concern at the very least to my family.

This was a rental car that I picked up on Sunday, June 22nd from national car rental at the reagan national airport. I was driving around 35 mph on a two lane road near stafford, va. At 4:20 pm on the 25th when the entire car shut off. I shifted into neutral to try and start it, but no luck. I applied heavy pressure on the now non powered brakes and came to a complete stop. I shifted into park and started the car. No further incident and turned the car in on the 26th and informed them of the incident. They marked the car so it would not be put back into the fleet until repaired.

As a rental vehicle to use while warranty repairs where being performed on my traverse; I had been rented a 2014 Impala. To my surprise the following morning I came to a stop and the engine quite, there was a clear lane within site that I figured I could push the dead vehicle to. I opened the door, while keeping my foot on the brake and positioned myself in the door frame to push. Then I removed my foot off the brake to reach in and place it into neutral and start pushing. To my surprise the vehicle started by its self and accelerated away from me, the door frame almost knocking me down, yet luckily I was able to catch the car and get back to the brake before the car crashed. I came to find out that this was an economic feature on that vehicle. I feel great concern that this car started when my seat belt had been removed and door opened, would they have at least considered some sort of precaution from this occurring. Please take this serious, I know that I was not advised of this feature, and had I not caught the car or gotten knocked down and run over, the outcome would have been much more serious.

Experience on multiple occasions the forward collision avoidance activation of a flashing a red light from dash into the front windshield and sounding an alarm with three or four beeps. Referring to this as phantom braking activated by the forward collision avoidance system causing autonomous brake activation and the cruise control disengagement. It is unknown if the activation of brake lamps occur I hope they work when this happen. My service manager suggestion is to deactivate feature. Chevrolet customer assistance center 71-1299424541 me back to the dealer with no solution/explanation.

On multiple occasions my 2014 Impala indicated imminent crash by flashing a red light from dash into the front windshield and sounding an alarm with 3 or 4 beeps. The first couple of times I thought maybe the sensor was picking up a shadow or parked car but as it happened a few more times I came to the realization that it was not operating correctly. On clear sunny days with no cars in front of me it began to occur. I've owned the car for 2 months and it has probably happened 15 to 20 times. After doing a little research it sounds like I'm not the only one in the country to have this problem and in fact if my car was equipped with automatic braking function I'm confident that it would have applied the brakes and caused an accident.

I find my link very difficult to use as compare to my 2011 Buick regal control knob vs touch screen. The ipod I use in the Buick or the usb drive was easier to use and navigate. I spoken to apple and microsoft techs about creating playlists but the function does not work in my Impala. This is a problem in 2014 Chevrolet Impala and the my link system that need correction. The I tune and media player is incompatible with mylink and GM should provide software/app that will work. To change a selection in mylink can cause distracted driving.

Battery leaked down the frame and was eating the 2 trany cooler aluminum lines. Autonation Chevrolet superstition springs in mesa, AZ put a new battery and 2 new trany cooler lines on, but after the 4th attempt can not get all of the acid cleaned up. Engine cradle still has no paint in spots and acid still showing on spots. After a day of rain. Went out to the car the next day and when I opened up the drivers door there was a very bad odor. Almost wanted to throw up. After looking all over the car found 2" of water were the spare tire is and all of the carpet wet in the trunk. Took it to autonation Chevrolet superstition springs in mesa, AZ. They had it for 2 weeks and they determined I did not have the trunk closed all the way. This trunk will not stay down. What I mean is the spring is so good it's ether closed all the way or open all the way. After that and some research I found GM has put out a #PI1133 trunk water leak. The seal around the rear tail light leaks water into the trunk. So I took it back to the dealer and had to tell them it was not me leaving the trunk opened.
