Owner reports
Selected complaints filed with NHTSA by 2014 Chevrolet Impala owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2014 Chevrolet Impala. The contact stated that water was entering the rear tail lamps, causing the amplifier and radio to fail to operate. The contact was concerned that the failure could cause an electrical fire. The vehicle was taken to an independent mechanic, who determined that the tail lamp gasket needed to be sealed. The vehicle was not repaired. The contact related the failure to Technical Service Bulletin: 14047 (Tail Lamp Gasket Seal); however, the vehicle was not covered under the TSB. The manufacturer was not made aware of the failure. The failure mileage was approximately 48,000.
Multiple electric concerns...airbag light, park assist, inop camera, and losing communication with BCM(?) Found multiple communication codes for a variety of different modules. Found main source to be from the "side detection modules". Found fuse 62 blown underhood. Inspected side detection modules and found "a lot of corrosion" on both modules and connectors. Needs side detection kit. I purchased the used impala on 12/19/2020 with 63,897 miles. The first time this issue was a concern was on 07/02/2022 at Merit chevrolet (MN). Mileage was at 83144 at that time. Diagnosis ... recommend both rear side detection modules and harness? According to Special coverage adjustment #N172097060 it is known to be subject to "water intrusion"? This problem affects the whole electrical system which includes airbag function. Why does this safety concern have a limited coverage time? …
Driving at night my car headlights/instrument panel shut off on their own. I couldn't see had to slam my brakes and pull over. Nothing I tried would turn them on. After almost a minute each time they just came back on theirselves. After googling this seems to be a known problem with Chevy impalas but no solution. This is highly dangerous. There were no warning lights that came on or anything. I was able to still drive the car, turn it on and off, etc but they wouldn't come on until they did on their own. Thank goodness no one was behind me or something in front of me cause I was on a none lighted 55 mph road

Yes, morries forest lake chevrolet and cadilac.forest lake. mn... no it has not been inspected by anyone but the dealer...There were no warning lights untill 51,000 miles or 8 months ago
The lighting is unsafe at night, the light does not light up the road so you can safely see what is is front of you, ITs a major design flaw in the light housing, upgraded to a brighter bulb does not help.
Tl* the contact owns a 2014 Chevrolet Impala. While driving 30 MPH, the headlights turned off and on.

Around 3 years ago. 3 parts the lane departure modules control are the blind spot sensors, rear backup sensors and a front camera. My lane departure modules got wet and messed up my car where there were many things going wrong. While I was driving my car said the air bag went off, theft was detected, blower fan & temp controls where going on and off while I was driving. 2 years ago GM agreed to replace the modules. The dealership said they were having problems with the programming of the modules. They finally got them to program. The day I picked up my car I noticed issues with the sensor system. They said to drive it. I took it and the problem got worse. With the blind spot sensor, on the passenger side goes on and off all the time, I have pictures and videos showing where I am driving with no vehicle next to me at all with the light for the sensor shining bright. …
I pulled into my garage and cut of my car. After opening the door my seat wouldn't move forward like it always does. That's when my dash board gave me an error message stating that I need to roll my driver side window down. So, I did that but the next day my navigation system was off along with my radio and on-star system. So I drove to the gas station before heading to work, and when I tried to get in my car the power was off. I went under-hood to see if the battery was loose but it wasn't. So I shut the hood got back in the car and everything including my radio, GPS, and on-star came back on. I headed out to work and that is when my car shut off while I was driving on the freeway at 70 MPH and the error message said warning no power steering. …
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. …
I have a serious problem with the 2014 -15 Chevy Impala lighting, the headlights at night do not shine or fan out to see when turning right or left on a darkened road the lights seem to be adjusted to a pin point setting straight ahead. I was tuning left from a road to a unlit road that was totally black when looking out the left side window to turn when I turned I was headed for the woods luckily I wasn't going fast so I could back up to turn to the road there should be a recall to fix this problem before there are some accident's because of these headlights there could be a person crossing a street that you won' see on a dark street turn. Very dangerous situation. I have seen the same complaint odi # 10651739 & others please fix the problem before its to late thank you.
