Electrical wiring problems. Parking light wouldn't go off and clicking noise under dash in front seat.
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 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.
Side detection system sensors are located on the inside of the rear bumper panel on either side, they detect cars in the blind spot. The sensors are located in a poor location to begin with, they are in direct line of fire with road and tire debris, salt water, gravel, sand, snow, mud, etc. Over time, the natural elements seep into the cracks of these sensors and/or their wiring harnesses at the connections, and cause malfunctioning of this system. Minimally, the problem can be resolved by replacing the sensors and/or harnesses for brand new ones. At the worst, these malfunctioned sensors cause other electrical malfunctions and subsequently increased road hazards and driving conditions by the way that it can lead to the driver info center going black, the radio cutting out, all the interior and gauge cluster lights going out while on the road. If left unresolved because many customers and drivers would much rather wait for an official recall and continue driving, many will be at risk.
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.
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.
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 a faulty left side detection module. 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. 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.
Tl the contact owns a 2014 Chevrolet Impala. While driving, all the warning indicators illuminated, the speedometer failed, and all the functions of the air conditioning unit failed. The vehicle was taken to the dealer (sarchione Chevrolet, 1572 OH-44, randolph, OH 44265) where it was diagnosed that the obj sensors and wiring harness failed. The vehicle was repaired. The manufacturer was notified of the failure and a claim was filed. The failure mileage was 49,700.
When driving at low speeds or cornering at steep angles the traction control activates and will almost stop the vehicle. Previously had issue repaired under warranty and they replaced a wiring harness. Issue occurred again. A dealer service tech informed me that there is an issue with water getting in the harnesses but there is no recall only a technical service bulletin. Where it is a known issue that effects the traction control and abs I feel this being a know issue should be addressed though a recall as the repair is expensive and a safety concern.
