There are 50 owner-reported electrical system complaints for the 2014 Chevrolet Impalain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I received an alert to service the sideview sensors. Also, the sideview alert keeps flashing in the side mirrors even when there's no vehicle present.
Service side detection system came up on the display while driving on the freeway at 65MPH.
Side detection system failure. I have had 3 harness replacements on driver side. 2 harness replacements on passenger side, and a module replacement just 2 years ago. This failure causes my instrumentation to shut off, turn signals not work, and shuts off cruise control when in use. I have read outher more extreme cases like engine compartment fires or car shutting off while driving. I believe all these should be considered safety issues. I have owned this vehicle since new.
I previously owned a 2011 Buick Regal and now have a 2014 Chevy Impala. Both vehicles have had a Stabilitrack warning come up. Both vehicles experienced the same issue. The car seemed to jerk, lag in speed, cannot accelerate over 40mph. The Regal was diagnosed with an electrical/wiring issue. The Impala was diagnosed with a failed Transmission Control Module. We now have a 2016 Impala and the same issue and warning lights have appeared. That’s 3 vehicles we’ve owned from GMC with the exact same issue. This can’t be a coincidence and should be looked into. There are hundreds, if not thousands, of more consumers on forums experiencing the exact same issue. This should be recalled! Imagine the possibilities of danger this can cause when on the interstate and can’t accelerate over 40mph.
My back window exploded. The defrost system blew up while driving it's Brown burned marks in my window where the defrost runs
The side detection module has just failed out for the second time in under 2 years, 20k miles on my 2014 Impala LTZ. The first time it failed (less than two years ago), the side detection indicator on the mirrors started to go off randomly, and then eventually, I was unable to reliably lock/unlock my car. Eventually, it wouldn't even start/shut off (Push to start), and the entire dash was off even when running. It messed with seemingly the entire car's electrical system, and made it unsafe to drive (imagine if I would've been on the highway and the car shut down, plus I didn't have any gauges at all). As stated, this system (and side detection module specifically), has corroded and gone out again, despite this module supposedly being better sealed. I had a GM dealership replace the entire system with their kit, which was out of their specialty 80k mile warranty for this system, as they realize it is flawed but refuses to recall it. This kit was approximately $1000 installed, and I am again looking at the same price for a flawed system that GM is totally aware of and one that has safety implications and makes the vehicle undrivable.
My blind spot detectors went out, now as a result most of the electrical stuff no longer works. The car powers on and drains the battery randomly and the speedometer doesn’t work. Every light comes on from front camera, abs, and even power steering. I didn’t feel safe taking my kids to school and now I don’t feel I should pay $1,300 out of pocket.
Every year the side sensor goes bad.. This causes vehicle to loose important factors while driving. Headlight go off and on. Speed goes to 0, all codes flashing, gas and ram gone. Car also locks and unlocks randomly along with no heat or air.. This has happened twice even after fuse is pulled while waiting on yet another $1000 repair. This is so very unsafe. Car needs to be removed from roads or side sensor part coverd.
Back windshield exploded/shattered d/t short in defroster. This is the THIRD time this has happened in 5 years, first 2 times were in 2019.
Module kit needs replaced due to water getting in it... had been replaced less than 5 years ago.
My vehicle is exhibiting the exact systems outlined in NHTSA bulletin PI0924B: Some customers may comment on unwanted opening of the trunk without pressing any of the release buttons while the vehicle is parked. Although the trunk is unlatched while parked, the owner may not observe the trunk open until they begin to drive the vehicle. This may also be accompanied with a “Trunk Open” message in the DIC. This condition may be caused by the trunk release button on the remote transmitter being pressed inadvertently while the transmitter is in their pocket or purse.
Messages for “service side detection system” and “service rear vision system” appear web vehicle is turned on. Side detection system as well as backup camera are both non functional. GM knows about this issue and had a recall/ warranty repair program. however I was never notified to bring my vehicle in to have this repair done, and now I believe it is past the date that was set to have repairs covered. Will be contacting GM to have these things potentially fixed.
On July 11th 2023 I finalized the purchase of a black 2014 Chevy Impala LT at Premiere Auto Solutions LLC. The beginning of the week of July 22nd I started hearing loud noises coming from back tire area. On approximately July 24th, the engine light came on for small Evaporation leak code. Returned back to Premiere Auto and spoke with worker\dealer about situation with the car. Was told by this person after a test drive with him that the back tire noises are normal due to the braking system, and he cleared the engine code from dash panel. Within the next week, back tire noise got worse and engine light came back on along with message to service front camera\side detection system. Car diagnosed by two mechanics for replacement of back rotors\brakes and Evaporation purge valve. Attempted to contact Premiere Auto to no avail. On August 4th the vehicle suffered an electrical failure with total loss of power while driving. On August 7th the car was towed to Bob Johnson Chevrolet at 1271 W. Ridge Rd. Rochester, NY, 14615. The car is still there diagnosed with a shorted wire to the front camera module which renders the car inoperable, and is not covered by the extended warranty.
My car has had a the side detection modules fail every 1 to 2 years since I've owned the car new in 2014. The dealership has repaired it for free every time now for at least 5 times. Now that the car is not under warranty they refuse to fix it for free. This is a problem with the design and engineering of the car and it is very costly to fix. The problem will continue to occur since the manufacturer refuses to find a permanent solution to the issue. It is related to the placement of the unit and it is affected by the environment and corrodes.
The right turn signal bulb keeps blowing. Break lights were stuck on. I got pulled over because the blinker wasn't working and parking light wouldn't go off. The officer was nice because I had just got the car and didn't give me a ticket, just a warning. Blinker on passenger side won't work with lights on and fuses for that side keeps blowing
Electrical wiring problems. Parking light wouldn't go off and clicking noise under dash in front seat
Gages are going up and down. All lights keep coming on and appears to dying while driving. Turns dignals do not work when this is happening. My car has been with dealer (2298 Crain Hwy. Waldorf, MD 20601) for two weeks. As of Jan 3, 2023. They are offering to replace the chassis however not following the notified recall. Insisting that I pay...
