NHTSA complaint #11340587, filed 2020-07, 62,125 miles“I owned a new 2014 Chevrolet Impala. The 2014 Impala had a backup camera system which was outstanding. I never had a problem with what I saw on the rear view monitor screen which was on the dash of the Impala. I traded in the 2014 Chevrolet Impala for a 2018 and now there are two major problems with the 2018 Impala back up camera system. First, if there is a light rain to a heavy rain you lose 80% to 90% of the clear vision on the monitor screen. Not once did I ever have a problem with my 2014 Impala. …”
NHTSA complaint #11131040, filed 2018-09, 100 miles“From december 22 thru 27, 2018 I rented this 2018 Chevrolet Impala (california plate 8dve598) from hertz at the hotel del coronado, coronado, ca. For the first 4 or 5 backups the reverse camera display worked properly. That is it came on when I shifted into reverse and went off when I shifted forward. Then suddenly it stayed on for the rest of the week. We could neither get it to go to the normal icon display nor turn it off. It would not reboot when the ignition was turned off. Safety consequence--at night the display is so bright that it completely blocks right front quarter vision. …”
NHTSA complaint #11176113, filed 2019-02, 10,843 miles“Adaptive cruise control (acc) issues scenario 1 first day I was traveling at approximately 70 MPH. As I would in any of my other 100 + cars I've owned, I held the cruise control 'set' button expecting the speed to gradually decrease. The Impala much to my surprise, with traffic behind me, went from 70 MPH to approximately 20 MPH within 7 secs. The traffic behind me was swerving to avoid crashing into me. It clearly states on page 182 of the owner's manual 'reducing speed while acc is at a set speed. 'press and hold setuntil the desired lower speed is reached, then release it. …”
