When the rear detection system controller get controller it can take down the vehicle communication buss which takes out all functionality of the instrument cluster. All gauges quit working as well as turn signals. The vehicle was in motion when this issue occurred.

My whole electrical system failed! my side detectors stopped working the forward collision failed all at the same time. I had smoke coming from the rear bumper. Then I was getting all kinds of messages airbase, ABS, traction I lost all the gauges no speedometer nothing the heat would come on and stuff off all by it self. Before I could make it to my schedule appointment at the dealership to get checked out it died I could get it started anymore!! very unsafe when you are driving down the road! and very frustrated with gum because this is a very common issue of failing modules.

The blind spot monitoring system failed on my vehicle at only 62,000 miles. The modules and harness are mounted under the rear bumper cover behind the wheels where moisture dirt and road salt enter causing corrosion and possible fire. The passenger side notification light stayed on for two days straight even when the car was off. It is not fused in the back of the vehicle only under the hood. These safety components should be mounted in the trunk per industry standard or sealed with proper weather resistant gaskets at the very least. The harness was corroded so badly it was jumping the connection and blowing fuses. The modules were visibly swollen from having moisture inside and rust forming. I contacted GM and they would not cover the repair. There should be a full recall if not a special coverage on this safety issue, it is very serious and very costly. My garage/house could have burned down or I could have been involved in a vehicle fire or accident due to loss of safety feature.

The rear side detection modules corroded due to bad placement on the vehicle. The module is directly behind the rear wheel without any shielding, so when the snow and salt from the winter came off the tire, it would land directly on the read side detection module causing corrosion. There are a ton of forums online such as here https://www.cargurus.com/cars/discussion-T54868_ds885696. Chevy had this problem in 2014.5-2016 model but won't cover it even though they changed the modules in newer models to protect against the elements better. They know there is a problem but refuse to fix it for older models.

My car was experiencing intermittent issues with the side blind spot monitoring system when my car's dash stopped working while traveling on the highway at 55 mph.. I had several service system errors` `for `side blind spot, front camera, tire pressure monitor etc but most concerning is that the directional would not function, the gas, speedometer, and the tachometer did not function. It was dusk and it appeared the automatic lighting control stopped working as well. I stopped safely and turned off my car and tried to restart the car and the push button start would not work. I was able to restart the car by putting the key fob in the factory pocket designed to start the car with a key fob with a low battery. I was able to get my car into the Chevrolet dealership and they confirmed that the side blind spot modules were bad. They disconnected the modules and my car's dash function returned with just a warning to service the side blind spot system the dealership provided me a copy of a GM service bulletin #17-na-154 service side object detection message stating to replace both modules and the wiring harness need to be replaced for $1,638.91. I had already replaced one module 13 months earlier for $720. This failure mode is unacceptable leaving the car in a dangerous state without directionals, important gages like speedometer and fuel, and possibly no automatic lighting controls. The designed failure mode should be solely a service blind spot monitoring system leaving all other systems operational. Currently I am told that all parts required to fix my car are unavailable. An advanced safety system that is dangerous when it fails is neither advanced or safe.

Side detection module went out on both side after it was impacted by rain. I was told by the dealership that there is a new module however I would have to pay $1300 for it because it is sealed up better and less likely to receive water damage. I was also told that if not fixed that my car wont start and I would have other electrical issues. Other people have said they their module have caught on fire. Bad part Chevrolet this needs to be recalled asap.

Side blind zone alert stopped working due to the poor design of the modules. This caused my gas gauge and odometer to stop working. In addition, the following lights came on and said they needed to be serviced: Air bags, tires, theft system, check engine. After all of this, my car wouldn't start. I was left stranded. The faulty modules scrambled my computer in my car. The cost of this repair is around $1400 to fix, plus the modules will fail again and need to be replaced again. The modules are a poor design from GM. This seems to be an ongoing issue with these cars. Currently, GM hasn't been held responsible to fix the design of these modules. Not only do we have to pay for the repair of the faulty modules. We paid and still pay a hefty price for this vehicle. I wish I knew about this issue before I purchased this car. My car was parked and when I tried to start it, it wouldn't start. I finally was able to start it. As I drove it to the shop, I didn't have any speed odometer, turning signals or lights. This was very dangerous due to driving on a 4 lane highway in a busy city. To lose all gauges, lights, turn signals and to have other numerous "check" lights come on is very unsafe. I could have been rear ended.

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.

- Grand Rapids, MI, USA

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.
