Bad wiring harnesses causing brakes and antilock brakes to throw codes and fail. Abs and stable track fail and also cause car to suddenly go to low engine power mode while driving down highway. Replaced nearly every brake component plus vehicle computers and abs modules. Vehicle now throwing new codes serious at random. Main pcm computer replaced twice. Abs, brake booster, abs modular, master cylinder, 4 calipers, hoses, abs module and abs valve assembly all these components replaced twice at least. Vehicle was not a flood car.
The contact owns a 2014 Chevrolet Impala. The contact stated that the side detection sensors that illuminate on the rear-view mirror failed to function as intended. The contact stated there was a special customer program released however they had missed the expiration date by one month. The contact took the vehicle to the dealer who confirmed that the side detection sensor, modules and wire harnesses needed to be replaced. The contact later found that the wiring harness associated with this system was prone to corrosion and needed to be replaced. The vehicle was repaired however the failure continued to occur intermittently. The manufacturer was made aware of the failure. The approximate failure mileage was 44, 786.
51,000 miles. System has failed three times. first two covered by Warranty. Not under warranty now. There are numerous complaints about this problem. It will now cost me up to two thousand to repair. car is at risk of fire, failure to start and other major electrical problems. Dealer wants $140 to diagnose, I am afraid to drive this car.

The electronic parking brake fails to disengage entirely from the rear brake pads causing them to become welded together. This results in extreme heat, excess brake dust, poor acceleration, and caliper / brake line (air) issues.
Water enter in through trunk ledge seals to the degree of shortening out the harness, radio dash lighting camera back window. The floor of the trunk was soaked as though water wad poured. The water was standing a lot in the spare tire well. There was another customer with the same year make and model vehicle that had the exact same issue days prior to visit to dealership.
The linx radio stopped working. The onstar system stopped working awhile after the linx radio stopped working when the car started to operate off of battery reserve (or what I think is battery reserve --- the light on the dashboard changed to blue). I've had to change the batter twice in 2.5 years. I'm told the battery Duralast is a good battery and that its an electrical fuse problem and it would be difficult to find which wire is the problem. The vehicle has been inspected by three different dealers in three different states. I was also told to uninstall onstar for resolution of the electrical problem of the battery draining and needing to draw energy from another source taking up more energy than it's suppose to in the vehicle. Yes, in 2017-18, the problem was confirmed by the dealership where I purchased the car brand new in 2014, Criswell Chevrolet in Gaithersburg, MD.
We have had several problems with the blind spot sensor on our 2014 Impala LTZ. Problems would always occur when driving in rain or snow. Dealer would just say that the sensor gets wet and that we should try to dry it off. Once the sensor was dry it would work ok. Now the sensor does not work at all. Took it off and it was full of corrosion. Reading online regarding reviews I find out that this is a very common problem with GM vehicles but GM refuses to do a recall. However they did do a special offer to replace the sensor if you have less than 80,000 miles. My car has 85,000 but I have dealt with this problem for several years. I replaced the sensor myself (at a cost of $400) and now they tell me it has to be reprogrammed. That really sucks. It is too bad that GM just can't accept the fact that they have a faulty product. I am currently waiting for a call back from the dealer to see what it cost to get sensors and wiring harness replaced (GM admits that there definitely was a problem and says you have to replace both sensors and the wiring harness). How in the world can this not be a recall!!!!!!!!!!!
Have had car at dealership 3 times total for the side detection system message/blind spot indicator lights. First two times the issue was fixed because I have the mpp coverage plan. This time mpp would have covered it but mechanic shows water intrusion. Their was a recall at one time for vehicles up to 80,000 miles. Mine has 124,000 so not covered but when I took it in for the same thing prior did not have 80,000 miles. So either pay the $900 or pay the diagnostic charge of $155 and walk away with issue not fixed. So many complaints on this and GM has done nothing. If I have fixed the module is over $200 for the one side. It keeps going out. GM should fix this and create another recall for this all so common issue!!

The vehicle was taken to Chevrolet of homewood (18033 S halsted St, homewood, il 60430) to be diagnosed. The contact was informed by the mechanic that nothing needed to be replaced. The contact had the rotors replaced on the vehicle however, the failure persisted. The vehicle was taken to mike anderson Chevrolet of merrillville (1550 E 61st ave, merrillville, in 46410) for a second diagnostic test. The mechanic was unable to provide a cause for the failure. The manufacturer had not been informed of the failure. The failure mileage was approximately 74,000.

Received letter from GMC in March 2020 regarding electrical wire leading to passenger seat not deploying and may become disconnected and fail to deploy when commanded. Also an indication will be displayed on the dashboard. My car is experiencing this issue and GMC fails cover the cost because its not identified as recall. The states they will cover for no charge if within 8 years of originally placed in service or 80,000 miles (whichever comes first). GMC should already that 2014 cars will be well 80,000 miles in 2020! since this is a safety issue and lives are at stake, GMC should not make this financial burden for consumers. Additionally the electrical wiring for the entire system is an issue. My screen continues to blink in and out and show a system refresh and the radio, bluetooth capability, and locking mechanisms are inoperable as well. All of these issues started at the same time! GMC needs to take the same steps regarding airbag safety as Ford has done for their consumers with out of warranty vehicles! Ford is providing a free service to their customers because they value the lives more profits. I've taken vehicle for service today (4/9/21) and I'm looking a a healthy bill. Hopefully electrical/safety issues can be addressed with GMC as this issue has been identified in multiple forums including this website. The number associated with the electrical airbag issue is N192216430. The electrical issues with screen and airbag was identified when starting the car and no connection and airbag indicator on dashboard. This happened around June 2020. I spoke with Chevrolet customer assistance center today (4/9/21) and no help was offered for this issue.
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.
