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

Side detection module malfunction. Causing electrical issues and error codes. When happening Headlights Turn on and off without control. Huge safety problem when driving at night!

- Stanton , MI, USA

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

Side section doesn't work light on mirror is constantly on today every light on the dash was on the headlights were flashing on and off while driving down the road none of the gauges worked no heater controls or heat was not working the air bag light is on all service reminders came up on the display the radio also doesn't work traction control and stabilitrac doesn't work!! air bags and headlights not working properly is my biggest safety concern!! the car did this stationary and also driving down the road!

- Somerset, WI, USA

The brake light in the window flashes on and off all the time and even when car is parked and shut off it flashes and when it is in motion. The cruise control will not work and device stability traction control warning is on and says it needs to be serviced. Vehicle only has 28000 miles on it.

- Rudyard, MI, USA

The headlights are so dim that I can drive with the high beams on and on coming vehicles ever flash their headlights high beam are as bright as the low beams should be. This is extremely dangerous with this poor lighting. There needs to be a recall, checking the internet there have been other complaints file with NHTSA

Gasket seals on the rear lights are leaking and the trunk is filling with water where the spare tire is stored. Causing faulty brake lights and water damage to the body of the car and black mold.

- Port Crane, NY, USA

The contact owns a 2014 Chevrolet Impala. The contact stated that the driver's side brake light malfunctioned due to a faulty gasket that allowed water to leak into the trunk of the vehicle. In addition, the battery power would drain although the vehicle was turned off and the odor of mold and mildew were present inside the vehicle. Gray-danial Chevrolet (6060 I-55, jackson, ms) was notified of the failures. The manufacturer was not contacted. The vehicle was not diagnosed or repaired. The failure mileage was 800.

While driving, several functions in the car will turn off. Functions include heating/ cooling system, lights (dashboard lights), doors lock/ unlock and collision systems turns off. I've researched online and found several other customers have had the same issues ranging back to 2018. I've taking my car to a GM dealership and found that the sensor malfunctioned and needed to be replaced. I also found the sensor is on back order, which makes me believe this is a larger issue than I thought and some one needs to investigate further. Driving along the highway and several security features start to turn off is dangerous.

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. Research of online customer forums shows that this problem is common with the latest generation (2014 and newer) Impala. The blind spot detection system is connected to the instrument cluster and this occurs randomly while driving.

When my side detection monitoring system failed a few months ago I took it to a local dealer. They responded telling me that, unfortunately, the design for this sensor module/harness is completely flawed. The sensors are located in the rear bumper, with plastic housing. There is no weather protection, even though these are directly behind the tires and are exposed to all weather - plus I live in il so we're talking rain, snow, salt, etc. It's two sensors and the harness. I couldn't afford the $1200 repair, so I figured I would just have to deal with the loss of the safety feature and ignore the warning light. Last week, all of my warning lights came on - theft detection, front camera, airbag, stabilitrack, etc. My windshield wipers, turn signals, locks and headlights were all going haywire, and at one point while driving all of my gauges went to zero (no speed limit, RPM, gas gauge, anything) and my heat went out, turn signals stopped working and my headlights went out. Immediately took it to another dealership hoping that maybe my battery (factory original)/wiring might be the cause. No such luck. As it turns out the side detection modules are now corrupting all sensors and electrical systems including my air bags! the dealership confirmed that the side detection modules had failed and were causing the chaos that is occurring with all of my other warning systems, and that my air bags no longer worked. My air bags don't work because of this, nevermind the extreme danger in having a system go haywire while I'm driving! I'm at nearly 100,000 miles so I'm well past any warranty that would cover this, but I have been reading forums and carcomplaints and it turns out that this is a really common issue. The cost of the diagnostics, cost of the repair, and anticipated costs of subsequent repairs is ridiculous considering it is a known design flaw.

Right front head light low beam wire harness burns completely up. I also found the same situation on 3 other 2014 Impala limited while looking for a replacement harness in two different salvage yards. I think this is significant.

- Summerville, SC, USA

The contact owns a 2014 Chevrolet Impala. While driving 30 mph, the headlights turned off and on. The contact made an appointment with mike smith Buick GMC (6014 S transit rd, lockport, NY 14094, (716) 625-8235) for diagnostic testing. The contact stated that the failure first occurred last year. The dealer diagnosed that there was an electrical failure, and the wires were burnt and corroded. The contact stated that the electrical wiring harness was replaced. The manufacturer was notified by a letter that was mailed by the contact, but no response was received. The failure mileage was approximately 39,000.

Hid headlights are very poor, returned to dealer numerous times, was told they are working as intended. While driving at night changing from low to high beam can't tell any difference!

- Cannelton, IN, USA

Poor headlighting. Foggy lense due to defective lense material fogging from the heat on the inside of the lense, poor light color, too small head lights. Very hard to see properly, especially if there is a slight mist or rain. There is not enough lighting, the color makes every thing shiny. Hard to see the lines in the road and road edges. Poorest car lighting I have ever owned. The dealer says there is nothing they can do to improve the head lights.
