What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“The contact owns a 2014 Chevrolet Impala. While driving at an undisclosed speed, the Stabili-Trak warning light illuminated and the vehicle lost power steering functionality, causing the steering to become extremely firm. The contact stated that excessive force was needed to turn the steering wheel. The contact safely pulled over, and after the audible alarm ceased, the vehicle returned to normal operation. Additionally, the vehicle lost electrical power and stalled on several occasions. There was no warning light illuminated. While the vehicle was stationary, the vehicle frequently lost power. The contact stated that the battery terminals were disconnected and reconnected after the failure, and the vehicle operated for approximately 15 minutes before the vehicle stalled again. The manufacturer was notified of the failure. The local dealer had inspected the vehicle and confirmed the failure. The dealer had retrieved several unknown fault codes. The vehicle was not yet diagnosed.”

“I have a 2014 Impala limited I started having problems within 6 months after I bought the vehicle from Bergstrom Chevrolet in Wisconsin it was involving the ABS anti-lock stability track and traction control and the braking and steering we're all feeling and locking up while I was driving it presented and problems and endangering my life and the life of any passengers in the vehicle the brakes will lock up and there was no warning before I locked up no lights came on and it would pull to the left or pull to the right depending on which ABS was locking up and it was fixed one time at the dealership then it was fixed again at the dealership later maybe about another 3 to 6 months after and went up for the same thing again and the parts were replaced now I again have had nothing but problems with the braking system. Also the valve that controls the pressure in the fuel tank malfunctioned which caused the car to run irrraticaly it would start hard,stop running at all stops rough ideling and unable to pump gas into the car without the gas pump stopping continuously making the time that it would take to fill the gas tank 3 to 4 times longer than it did that was fixed…”

“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.”

“Very loud abnormal ticking sound coming from the vehicle, failed actuators. Resulting in hvac loss. Arecall issued in 2014 for stabilitrak /abs for bad grounds on 2014 Chevy Impalas. HOWEVER 2.5 and 3.6 L engines were not included, BUT NEED TO BE!!! the car will drive rough and eventually just cut off in the middle of traffic highway or residential. This is what it did on me, putting me in a very dangerous position with my 5 year old in the car. This issue is effecting thousands of the same vehicles and GM's failure to address this issue is leaving the owners of the affected vehicles driving unsafe vehicles. GM / Chevy needs to issue a recall on ALLL the 2014 Impalas. (which they will not confirm or deny). While I was driving 60mph on an interstate my car notification screen displayed "service stabilitrak"/ "engine power reduced"... then my car acceleration seemed to have died and car slowed all the way down to around 20 mph with the gas pedal diwn to the floor... a big semi truck was behind me and had to break and swerve around me while blowing his horn...I was nearly killed.”

“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.”

“The brakes continue to malfunction I am unsure if a previous recall was fixed properly or not the Chasis electrical system has been fixed with electrical tape only the transmission and stability track and anti lock brake system error light with go off from time to time when it does and the more it’s driven the worse the issues get these are all recalls and the problems still persist are we confident that the recalls have been corrected”
