2014 Chevrolet Impala: engine knocking or ticking

Filed May 29, 2025 · Brakes, Electrical · CO

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 was driving on a residential street, going no more than 25 MPH with my two two year olds in their car seats behind me. Suddenly and simultaneously, all four of the side airbags deployed (front and back), knocking my girls seats together, the front right side of the car dropped down and started grinding on the wheel. I was able to pull off to the side of the road thankfully. I turned the car off, and when I got out to look at the front, the car door shut, and for the first time, automatically locked me out, my kids inside, with its own key and my purse as well.

June 2016 at 20k miles the car was erratically shifting at 30-35 MPH and had a bad smell from the vents. I brought it to bonner chevrolet who stated they were unable to replicate the issue and it may be due to running too high of an octane of fuel. The issue was not resolved. October 2016 I brought it back to the dealership for the same issue but I also noticed a slight ticking noise. A motor mount was changed but nothing was done about the shifting issue or bad smell. They stated because the car was not giving any codes, there was nothing else they could do about it. August 13 2017 at 25 or 30 MPH while accelerating the car violently jerked my son and I forward. It also did this while downshifting. It continued to do this for 5 minutes until it began to no longer shift gears. The check engine light came on. It got to 4500rpm when I pulled over and shut the car off. I turned it back on after a few minutes but the issue continued. After another 5 minutes I got home. Monday 8/14 after arguing with chevy about towing my car since they didnt want to pick it up until 8/17, they agreed to pick it up that day 8/14. They also stated I would get a rental as long as it was determined the issue was a failure on behalf of chevy and not myself. Tuesday 8/15 came with no update from the dealsership. Wednesday morning 8/16 I called for an update and was informed the car had "internal engine failure". The service rep paul at valley chevrolet refused to give me the code the car was giving for the internal engine failure. He refused to give me a rental because the car has over 36k miles. I informed him this is conflicting from what I was told on 8/14 by customer service. He said that if I did not want the car fixed, that he could leave my car outside. No call back yet from customer service as the rental and transmission replacement should be covered under the powertrain warantee.

As a rental vehicle to use while warranty repairs where being performed on my traverse; I had been rented a 2014 impala. To my surprise the following morning I came to a stop and the engine quite, there was a clear lane within site that I figured I could push the dead vehicle to. I opened the door, while keeping my foot on the brake and positioned myself in the door frame to push. Then I removed my foot off the brake to reach in and place it into neutral and start pushing. To my surprise the vehicle started by its self and accelerated away from me, the door frame almost knocking me down, yet luckily I was able to catch the car and get back to the brake before the car crashed. I came to find out that this was an economic feature on that vehicle. I feel great concern that this car started when my seat belt had been removed and door opened, would they have at least considered some sort of precaution from this occurring. Please take this serious, I know that I was not advised of this feature, and had I not caught the car or gotten knocked down and run over, the outcome would have been much more serious.
