Three problems related to warning light on have been reported for the 2014 Chevrolet Impala. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2014 Chevrolet Impala based on all problems reported for the 2014 Impala.
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.
Right hand passanger roofrail airbag needs to be replaced according to peterson Chevrolet, the dealer where I purchased the car. Airbag warning light is on. Car has 62,904 miles on it. Seems to me this ought to be gm's responsibility to make sure the damned thing works. No event happened. The airbag warning light just came on while we were driving. How do I know who the airbag manufacturer was?.
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.
