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.

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? According to the "Special Coverage" document, there was an 80000 mile timeline? This appears to be an ongoing issue with this year, make, and model and my feeling is that a "special coverage" is denying the safety problem and putting it on the consumer?

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

Rear blind spot system failed, causing most electrical systems to also fail. Headlights, wipers, rear cross traffic, speedometer, instrument cluster, inconsistent gas pedal operation.

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. I got to work safely and realized I left something in my car and that is when my car show signs that it was dead, but after manually getting into my car the power came back on. I also have issues with water getting into my trunk which is what the dealership told me was possibly causing the issues. As a disabled veteran this messes with my ptsd and financially I cant afford to keep paying for an issue that I see my 2014 impala drivers have. I love the car but hate these issues. I need help with this car and the issues.

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. The rear backup sensor does not warm me, last week I did not see a garbage can behind me because it was lower than my trunk and I hit the can and broke my tail light. The front sensor that tells me I am going to fast for the car in front of me goes on randomly when the car in front of me is more than 100 feet or no car at all. I have taking my car to 3 dealerships 4 times. All the deanship's say they can't fix it because they don't get a code. There is no code for this, not to mention when my lane departure modules failed there was no code for it, they just stopped working. They say it is undiagnoseable. Gm saw the pictures and videos and are now saying there is nothing wrong with the system without looking at the car just the pictures and videos. How can they say nothing is wrong when you see in the videos the light is on and no car is next to me? How do I let my 15-year-old daughter drive this car with a light on when no one is there? Please help me! The safety and security system is not safe at all.

The headlights on my impala have some sort of discoloration inside the headlight assembly it's beginning to block the amount of lumens coming through for my lights to see. I'm certain this is a safety concern because they were designed to put out a certain number of lumens for night driving and now they aren't
