What 630 owners told NHTSA about the 2014 Chevrolet Impala

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 and it is malfunctioning again. I'm on my fourth time of having my car anti-lock brake system failing on my car multiple systems including the electrical system failing. The dash lights would go off on. The exterior lights going off and on. The car has been off of the streets and unable to be driven many times. I have taken my car in to the Dealership from where I purchased it from. By the third time my car warranty had expired. Then everything was still not repaired all the systems were not ever working correctly. And now the repairs were needed to be paid in full by myself. The cost to me had just begun when it should have been resolved. In excess of $6,000 was what it would cost me the third time I had the Impala in for everything and now it's gone out again and I'm having to get this repaired.

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.

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.

NHTSA ODI 11653691

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.

My back window exploded. The defrost system blew up while driving it's Brown burned marks in my window where the defrost runs

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

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.

NHTSA ODI 11584780

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.

NHTSA ODI 11570405

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.

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.

While driving the car electrical system will lose all power and reset. This happens often.

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.

I have a 2014 Chevy Impala LTZ, owned it for 9 years. Just started with issues within the last 6months and it just seems to be getting worst everyday. While making a left turn, not even driving 5mph my power steering fails and the drivers side tires seem to lock up as if the car would be hydro planing. Once it happens the dashboard Alerts come on such as Stabilitrac, Traction Control, ABS, Service Break Assistance, Power Steering, and I lost control of the car in the middle of the road!! Brought the car to the shop they change the wheel bearings. We also changed the brakes in March of this year, we had a front and back realignment plus new tires within the last 6 months. The dealer we got it from is no longer in business, as I did buy it used. I called the Chevrolet 800 number for recalls but no luck finding anything. After searching year/make/model I found similar issues to other "2014 Chevy" within the last couple of years. This is a serious issue and it can become dangerous while driving with my family in the car. I can't afford another vehicle as this car is my reliable vehicle.

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

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.

NHTSA ODI 11515681

Electrical wiring problems. Parking light wouldn't go off and clicking noise under dash in front seat

The contact owns a 2014 Chevrolet Impala. The contact stated that while operating the vehicle, the side mirror blind spot detection system malfunctioned, and the warning light blinked constantly and blinked while no oncoming vehicle was present. The contact stated that the failure occurred on both the driver’s side and passenger’s side mirrors. The contact stated that while the failure occurred the electronic cluster also malfunctioned, and the doors and trunk lid would not always open, and the vehicle would not always start immediately. The vehicle was taken to the local dealer who replaced an unknown module kit. The contact stated that the vehicle had been repaired for the same failure on three previous occasions. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 40,000.
