The side detection modules behind the rear tires are failing and causing all electronics to fail. This module goes bad and the traction control, ABS, blindspot monitors, HVAC, airbags, headlights and gauges all go out. This happens when when driving and is erratic in its behavior. It also makes the gas pedal hesitate and the car becomes a huge safety concern. It seems like it is a common problem due to poor placement.
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.
While driving at any speed the instrument cluster will completely die out. Blinkers not functioning. Seems like some sort of short. Also blind spot alert not working, forward facing camera, park assist.
Left rear side detection module and related wiring harness failed due to corrosion from exposure to water and weather elements during normal operation. Placement of module inside the rear bumper caused moisture to accumulate within module and its related electrical connectors. During failure, while operating the vehicle, module sent erratic signals to obc causing partial shutdown of key electrical components including turn signals and instrument cluster. This module has a high, pre-mature failure rate, due to exposure to weather elements and road salt in northern states. Chevrolet has difficulty keeping sufficient modules in stock at local dealers. Order out time for subject components is 3-5 buisness days.
The contact owns a 2014 Chevrolet Impala. While driving 55 mph, the door locks kept locking and unlocking, the headlights went out, while driving, but the motor kept running. My wife made it home. The (for about 13 to 15 seconds) next morning she took it to work, on the way it stalled and would not start. Consumer replaced the battery and still it would not start. But the vehicle would not start, an independent mechanic diagnosed that the blind side sensor was corroded and informed the contact to unplug the wiring harness from the blind side sensor. After unplugging the wiring harness, the vehicle was operable. The vehicle was not taken to a dealer for diagnostic testing or repairs. The manufacturer was made aware of the failure. The failure mileage was 55,000. Consumer stated GM has a bulletin out about corrosion in blind side sensor connection.

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.

Dealer service center diagnostic test showed a faulty left side detection module.

Research of online customer forums shows that this problem is common with the latest generation (2014 and newer) Impala. Replacing the modules (and in some cases, also the wiring harness, which becomes corroded from the weather) seems to be a short term fix at best, as the design of the blind spot detection system exposes the sensors and wiring harness to road spray and rapid corrosion damage. Furthermore, the blind spot detection system is connected to the instrument cluster in a manner that eventually renders them inoperative as well. This occurs randomly while driving.
I have filed a complaint last month about my 2014 Chevy Impala's side detection system, back up camera warnings, and forward collision systems all not working. Today I am adding that while driving on the freeway in moderate rain doing 55mph, my stabilitrak light came on, ABS light came on and I lost power steering. I did not lose control of my car, but it could have been bad. I called Chevy as soon as I got home to file a complaint. I will be bringing it to the dealership tomorrow as I have read other complaints of this happening as well with the next thing to go is the car won't start. This situation is uncalled for in a vehicle with 45,000 miles at a price tag of $35,000, especially when the other issues started happening around D 38,000 miles. Before today, when I started my car the service lights for front camera, park assist, and side detection all lit up. I did not take it to the dealership at that point because I heard it was expensive to fix now I have to as the safety of driving it is severely unstable.
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.
While driving 70 mph, my side detection light remained on and stayed that way for a few days then completely stopped working. I was still under 36,000 but over 36 months. I made an appointment with the dealership but cancelled after talking with my friend who said the same thing happened to her denali and it cost her $3000 to fix it. A few months ago, I was driving around 50 mph, all the sensors started flashing on my dash-parking assist, brakes, side detection, front camera, etc. The gauges stopped working, the heater turned off as did the radio and felt like the power was way down. My blinkers weren't working either. I pulled over and turned the car off to try to reset it and it did not work. I finished my drive to work. When returning to my car, it did not replicate the same behavior as in the morning. Now, my lane departure and front crash detection is not working. I have read many complaints about this issue in the 2014 Chevy Impala. I have always been, along with my husband, a GM product owner, GM has a plant 1 mile from us and they are talking about shutting it down. If this is not something GM looks into recalling, I may make the switch to a different car company. I have not yet taken it to the dealer but since more and more things keep breaking, I will be scheduling an appointment soon and letting GM know exactly how I feel about this. After spending $35,000 on a vehicle, it should not act like this.
Takata recall upon making a left turn, the ABS light flashes on and off, the engine grinds, and the car hesitates in the middle of the turn. On occasion the dashboard will indicate a stabilitrak warning. The pavement is dry and there no sand present. It happens most frequently when making a left turn after a complete stop. There are multiple forums by other Impala owners with the exact issue.
It would cut off and will not start with everything going blank thought it was the battery got a new one to replace the old one but still doing the same thing then the power steering light will come on sometimes when driving and we put in a new alternator thinking that it would solve the problem that didn't work still cuts off and won't start until 15-20 minutes had it checked by a mechanic and they couldn't find the problem scared to drive it do to having my kids in the car with me or going to work and it happens often then it should and only had the car for a year and a half and it have done it at least 5 times already
Having problems with my car when I do a turn in sterring wheel it makes a craking sound I hve changed brakes and other part in order to fix but did not solve the problem, also I braked hard once and the brakes locked and stayed that way I had to get vehicle towed because of this issue and this happen before new brakes, also when I turn all the light turn os as for brakes turning and other things.
While driving my car on a main street moving along at approximately 50 mph the car completely shut down, electrical system and motor. The car would not recognize the fob. Therefore, it would not restart. I put the car in park to restart. Therefore, it was stuck in park and I could not move the car out of the lane of traffic. We tried to re-set the system by disconnecting the battery and tapping the brakes. This did not work. After my husband had brought me the second fob from home the car still would not recognize the fob. I walked away from the car to re-set the fob. The car still would not start. After being struck in Friday afternoon traffic for an hour I called a tow truck. My husband tried the car again and it started. I drove the car home. The very next day I took it to the dealership and they could not find any problems. Two weeks later the car began not recognizing the fob again. The dealership cannot find the problem. I do not want to see any others get hurt from this problem.
The contact owns a 2014 Chevrolet Impala. While driving 65 mph, the vehicle lost power and the stabilitrac and check engine warning indicators illuminated. The vehicle was taken to johnny londoff Chevrolet (1375 dunn rd, florissant, mo 63031) where it was diagnosed that the side vehicle detection module failed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 99,000. The VIN was not available. *
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.
Power steering was lost, stability light came on - was told this was due to erosion - had repaired at my cost - extended warranty would not cover as techician stated my fault although apparently this area is not visible during normal service. Now the car twice has not started at all - all electronic sensors go dead. Have taken to Chevrolet dealer and they are unable to determined what is wrong. At least every other time I turn on car, the stability light or steering light come on, as well as the park assist light. I wait for about 10 minutes or so, try again, and they may or may not go off. 2 - the rear view mirror fell off during the first month I purchased, so it was under warranty and they "re-glued) it several times - finally it was recalled, and replaced about 15 months ago, now the mirror is doing the same thing again. 3- last is the pillar trim - it peeled and I had to have replaced at my cost - this should not have occurred. I fear I have a lemon, but more importantly I am not receiving the service necessary from Chevrolet dealer - I have maintained the service on my car through the dealer, but so many unanswered concerns leaves me at risk for accident should car just stop!
