The car electrical goes haywire. All these alerts and pop up come on ABS lights. Stabillatrac. No power steering. Looked up issue it has something with a bad sensor in bumper. Very dangerous

The issue started out as a warning from the side detection system. In the past week, the issue escalated to all the warning lights on the dash coming on, and then all electronics going dead/dark. The turn signal indicators have no lights and no sound, the radio system is dead, the speedometer and gas gauge are dead. After sitting a few hours, it seemed that things "reset" to just the side detection warning. Most recently, all the electronics are acting strange. Pushing the button on the door handle to unlock it, does nothing to the door lock, however, the display screen shows "tire learning active". when attempting the start the car by pushing the start button, nothing happens. If I put the fob in the slot inside the armrest, it will eventually start, but again all display functions are dead as is the environmental controls (no blower - no defrost- no good on a cold rainy day). Again the signal indicators are dark and silent. The indicator light for the airbags is now illuminated as well. GM had a short lived (and seemingly secret) extended warranty for the side detection system have this exact issue when water got into the sensors, but that expired nearly a year ago. As this issue makes the car unsafe to drive, it seems that it should be a full recall to address this safety concern.

The ABS light comes on. Everything on dashboard like the arrows go to zero and doesn't move. The oxygen sensor is not working. And some transmission problems. Also the car has proble!S moving at first. This happens when I am driving.

I had noticed the epb light coming on intermittently, far more often than every 50 key cycles, and began experiencing a significant decrease in acceleration, poor braking, brake dust buildup, uneven tire wear, bogging down when the vehicle would shift and when accelerating out of a slowdown and/or turn. I would also constantly smell brake dust and tire rubber and felt my brakes would become extremely hot to the touch after short trips. I observed the outer rear brake pads through the caliper and there seemed to be decent pad left. However I took my vehicle to the dealership many times and was told every time that there was no need to replace the pads. I was never notified of any software flashes to correct any known or unknown issues, and was once told that my brakes needed to be bled and after having the dealership service them was told the issue should be corrected. I had friends and family with automotive backgrounds look at my brakes and tell me there seemed to be no visible issues. I finally decided to have a look myself one day. After hoisting the vehicle up, removing the rear tire and inspecting the caliper and pads, I realized that the epb had actually heat/rust-welded itself to the inner brake pad which was completely worn with no pad whatsoever. The epb was actually unable to retract, even though the light was off, because the metal plate on the back of the pad had been fused to the epb. I had taken it back to the dealer who refused to look at it again, and was inevitably tasked with correcting the issue myself. I have spent hundreds of dollars on new pads, rotors, caliper pins, grease, tires, etc. Because of the persisting issue. When I searched my vehicle by VIN it told me there were no recalls, but after searching by year/make/model I finally found the recall involving the epb causing drag after failing to retract. This issue continues today.

The blind spot detection isn't working on the passenger side. Usually it doesn't come on at all, and every once in a while it'll come on randomly and stay on and not shut off even when the car has been turned off.

The computer with the radio component goes out causing all alarms, turn signals, and notifications to be silent. Also onstar and all radio components are inop. Temporarily you can fix the issue by disconnecting and reconnecting the battery but it will inevitably have to be reprogrammed. This is a known issue and is located in many forums.

For the second time since purchasing this vehicle new, the blind spot detection system is failing. When this system fails it slowly takes out the rest of the vehicles electrical systems, even those not related to any collision avoidance system. The first time I had it repaired it was out of the original warranty meaning I had to pay the approx. $1000 bill. A year or so later received a letter from GM saying that that repair would now be covered up to 6 years/80,000 mile and if I had already paid for such repair that I could file a claim and they would reimburse me for the previous work. Well amazingly they reimbursed me for the first repair, which was great! except now, the same exact thing has happened again and I am now past the 6 year 80,000 mile mark. GM needs to redesign this system to not be placed in high moisture areas or at the very least have a module/connector that is not susceptible to water intrusion.

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

Been having battery corrosion problems. All at once ABS and traction lights came on, steering got hard. I was driving when all this occurred.

- Bolivar, PA, USA

I was driving and the side detection system warning came up and my car started to malfunction right in the middle of an intersection. It would shut off, come back on, lights were flickering, and I lost braking control. Had to limp my car into a nearby parking lot. I know Chevrolet offered a special warranty for this issue, but it was like 6 years later, and half the people you find with this issue are outside the mileage they require. This is a huge safety concern, and Chevrolet should be the one to fix it.

I just got my car back from the dealer and not even a day later after they had it for 3 days they told me that they could find nothing wrong with my car. But as I am riding down the highway I was going about 65 and my car shut and came back on. I lost control of my steering wheel, then the car started driving normal. Once I arrived to my job and turned the car off. My vehicle shut off and the ignition lights along with the side panel lights was blanking but nothing else was on. I couldn't put my windows up and the car wouldn't cut on so I left it for a few minutes and walked back outside after 5 minutes because I noticed all of my outside lights where on, and at this time. I was able to cut my car on and off but I don't know what to expect when I get ready to leave. I need someone to contact me so I can get this fix because its becoming annoying and I am a disabled veteran and its working my mental.

I was driving with my infant daughter in the car when everything electrical in my car started going haywire. My blinkers did not work, my radio was on the fritz, breaking was cutting in and out, and my steering kept locking up. We were going through a very busy intersection in town too, and my car doing something like this could have gotten us both seriously injured or even worse. It did it once again a few weeks later while I was in the highway, but lucky I knew how to react once the problem started. I come to find out it's a 'safety feature' causing the issue. It's shorting out and causing the entire car to essentially shutdown. While. I'm. driving. If this isn't a safety issue in need of a recall, I do not know what is.

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.

I own a 2014 Chevy Impala ltz. During the winter of 2018 - 2019 I started seeing the side detection light come on randomly and staying on even when the car was not running. The problem progressed and one day as I was driving down the highway at 60 mph, at night, all powered systems flashed on and off including my headlights. I brought the car into the dealer and was told it was not covered. I reluctantly paid the $1,456 bill. A few months later I received the notice that there was a recall and I submitted a request for reimbursement, which I did receive from the dealer. Now a little over a year later I am having the same issues. I knew I needed to get the car back to the dealer. When I called to get an appointment they were three weeks out. Now just days before my appointment with the dealer, my car won't even start. All electrical systems flash on and off. My car has just under 80,000 miles. This is a major safety issue as it effects all electrical systems in the car. Most of the safety functions of this car rely on the electrical system.

The contact owns a 2014 Chevrolet Impala. The contact stated while driving at an undisclosed speed, the service blind spot detection system message displayed on the instrument panel. The contact stated that the failure caused blind spots to the driver's and passenger's side of the vehicle. The vehicle was taken to dunn Chevrolet (3000 dustin road, Oregon, oh 43616) to be diagnosed. The contact was informed that the side detection module and wiring harness needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 127,500.

My side detection module has gone out and is now causing other electrical failures. My understanding from online research is that this is a common problem attributed to design flaws.

Service side detection system. While driving this message comes on and when the car is stopped as well. [xxx] diagnosed the problem side object detection modules cost $841.21 plus tax. I contacted [xxx] from GM at [xxx]. I was told their is nothing GM could do as my car is at 11900 miles. This is a safety issue. This will cause car to possibly catch on fire, not to start and several other issues if not repaired. The blind spot detection system has been an issue in several 2014 Chevrolet Impala. I can't use the vehicle fearful of me and my children may be in danger. I've had 3 or more conversations with GM representative [xxx] but no help. The safety issues with the defective parts used during manufacturing is unacceptable as this is not a wear and tear item. My name is [xxx] my original case #[xxx] was filed with GM.this is a safety and should be considered as a recall. GM only offers repair if your vehicle is 80000 miles or less which is unfair to the owners of the vehicle who have experienced this problem. My number is [xxx] if there are any further questions that need answering. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
