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.
