2014 Chevrolet Impala: wrong fuel gauge reading

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.

I have a message saying service side detection. It has been on for months and didn't seem to be a big deal. It now has caused a bunch of other messages to come up to service. Everything on my dashboard stop working (speedometer, gas gauge, etc.) my heat is effected and at one point, my car wouldn't start for several days.

Tl* the contact owns a 2014 chevrolet impala lt. The contact stated that the side detection was malfunctioning. In addition, the fuel gauge, the speedometer, and the entire dash board failed to function. A dealer was not contacted. The manufacturer was made aware of the failure and informed that there were no recalls on the vehicle. The failure mileage was 64,000.

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 lane departure modules get wet and are located behind the rear tire. As a result the electrical system is now failing I get messages that my airbag has deployed. The gas gauge drops to empty. The heat in the drivers seat does not work. Now I have unexplained water in the bottom of my trunk with no sings how it got there. I honesty do not feel safe driving in it not know what will happen next and it my gauges tell me wrong information. Ie no gas

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.

Driving to work and all the emergency lights on my dashboard came on for no reason. The speedometer, tachometer, gas gauge, temperature gauge, radio and heater/AC controls and turn signals quit working. Additional warning lights on dashboard we're stabiltrac, ABS, air bag, tire monitor and brake light. Previous to this we had problems with the blind spot monitor system not functioning. The car has been at the dealership now for about 5 weeks with no answer. They currently have 3 other impalas with the same problem. We live in a town of under 10,000 people so what are the odds that we are the only ones. Sorry I do not have access to my VIN number at this time.
