2014 Chevrolet Impala engine problems

Filed Nov 15, 2025 · Brakes, Electrical · WI

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.

Fourth time I had submitted this text so this one will be vague. I've had to Repair my stuts and shocks and brakes to my vehicle due to ongoing issues with tires while divingand hitting small speesbumps and potholes. I did replace low performance tires and still was an issue with my struts and shocks when I drive causing me to hit a bump or a small hole and diverts me to the next lane of ongoing traffic also I had to my battery replaced twice. To find out that it was only due to corrosion and the battery cables slipping was frustrating cause I did replace the battery and key fob battery already. Car wouldn't start and when it did it took forever hours to restart and engine still seems to get bogged down In ongoing traffic. Which was the prior issue no power no matter how hard i press the gas. I took to autozone and they did a reading which came back that everything was okay including the battery which was obviously not okay. It was leaking fluid and i have already replaced year and half ago due to same issue. They cables seem to slip over time on its own. What to do? Thank you for your time to look into this issue. Kindest Regards

The 2014 Chevy Impala is dangerous. When the rocker arm control valve and related parts fail or the camshaft solenoids and sensors fail 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. The economic loss is still devastating financially as all 2.5 and 3.6 engines arent covered by GM special warranty but they should be all covered. My VIN number was not included when it should be.

When pulling up to a stoplight the car would often downshift, surge with power, and nearly overpower the brakes. The car started losing oil from its rear main seal. When I finally had the seal replaced the repair shop found that pieces of the thrust bearing were laying in the oil pan. The engine and transmission had to be removed from the vehicle in order to replace the thrust bearing. They showed me a box full of parts, but I did not keep any.
