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.

What owners say
I have push to start car. On my lunch i starting my car and I immediately notice the rpm went to 2500, which is high and it went up to 3000 and then the warning light flashed stability track error and check engine and swerving light I took a pic. I turn car off and wait a few min turned car back on and it was fine. No errors drove to get lunch and back no issues. Then on leaving work s ame thing happened but the error didn't go away. I was able to shift out of gear. Hard knocking, gear shifter light all white no clue what gear it was in I moved to another parking spot but was slow moving very delayed. Parked and now waiting for tow truck
I have a 2009 with 77000 miles 0n it I have fix the knocking noise under dash 3 times now it is a actuator there are 2 of them. I have also found by spraying Carburetor cleaner in the throttle body just remove the the big air hose and spray all around in side this stops the the speed reduction control lite from coming on saying you have no power. The problem I'm having now is while I'm driving the dash lights go out and radio light goes dim. after a while the lights come back on bright and working great they go on and off when they want to The lights showing me the mileage works great all the time its just the dash lights going on and off and my car just pass smog in California in June. I now live in Texas ,I have to have my car inspection here and it failed do to a EVAP and a 02 sensor not responding. They tell cause I replace the battery this cause the computer to reset and these 2 sensors have not reset yet and I have to drive the car 100 miles to make sure they reset to the computer So these are the problems I have been having with my car. You can find your car problem on you tube by putting in the year and make of your car saying what light came up and usually its a easy fix
The contact owns a 2014 Chevrolet Impala. The contact stated while driving at an undisclosed speed, the contact became aware of an abnormal ticking sound coming from the vehicle. The vehicle was taken to the dealer where it was diagnosed with a failed actuator. The contact was informed that the actuator needed to be replaced. The vehicle was being repaired. The contact stated that a total of eleven actuators had been replaced in the vehicle since 2018. The manufacturer was not made aware of the failure. The failure mileage was approximately 122,000.
My car's engine always feels like it's dragging in the front and sounds really really bad like it's about to explode or something it makes a lot of noise and ticking sound as well when I'm driving
Back driver passenger door is stuck. Will not open at all, locks don't unlock most of the time and don't lock at all. Always have to lock manually. New starter replaced but still seems to not want to start. Knocking noise in dash. Front passenger heated seat doesn't work, when the heat button is pushed the light blinks and turns back off. Vents don't work well. And vehicle is stationary, in motion... Also when vehicle speeds up the music gets louder ..
Able to shift gear positions but the indicated shift position does not represent the gear position the vehicle is in. When I stop and park the vehicle, I am able to shift the lever to the "park" position, but the vehicle is not actually in park position. I currently have the emergency break on. Vehicle will not stay in park when gear is in park position. The lightest touch will knock gear shift into reverse and car rolls away.
Transmission slips front end hits hard when bumps occur service air bag is on the dashboard actuator knocks
Purchased vehicle and the following day the right front headlight went out and had to be taken in for electrical problem. Later about 4 months after purchase the air bag in the front passenger seat started to make a knocking sound and then stopped. Just recently it began making the knocking sound again when I open my car door, as well as close it. It lasts about 3 minutes and then stops.
The door blend actuators go out constantly. The car has three of them. When they go bad, there is a loud clicking or knocking sound behind the dashboard and the air conditioner and heater stop working. If it's cold, it blows cold air and if it's hot it blows hot air. I have replaced at least 20 actuators. Once they go bad, a new one last only a few months, which means there is a deeper issue. The dealer says chevy is aware of the problem and it is a well known issue; however, they have not issued a recall, dealer could not quote a price because they won't know what is wrong until they get in there. Dealer suspects chevy won't issue recall because the whole system is faulty and will cost thousands per car to fix.
