Tl* the contact owns a 2018 chevrolet impala. While driving approximately 50 MPH, the contact's vehicle was involved in a front end collision with a deer. The air bags did not deploy. A police report was filed. The vehicle was damaged and towed to an independent body shop. The manufacturer and dealer were not notified. The driver sustained injuries that required medical attention. The failure mileage was approximately 2,000.
October 10th, I was in an accident where I was literally an entire car length back driving with the flow of traffic at 50-55 MPH, when the vehicle in front of me came to an abrupt stop on the freeway. I slammed on my brakes but my car slid straight into the back of the vehicle in front of me. It felt as if my brakes were not stopping my car. I noticed this happening before on a main street and I was travelling at 45 MPH but I did not think anything of it at the time.
In february 2019 I purchased a 2018 chevy impala premier, upon driving the car I noticed that the brakes were not working like my 2018 chevy camaro but I chucked it up to the car being heavier and paid it no attention. For months I have been thinking that maybe I just need to get used to the brakes on my new car and that it was nothing. While I drive at normal speeds (40 - 45 MPH) my car slid an extra 5- 10 ft more then it is supposed to every time.
Stabilitrack and engine light came on at the same time with a message that said, 'engine power is reduced'. This occurred as I was driving on the highway. The vehicle gradually slowed, but I was able to maintain a speed of 55 MPH. I was unable to accelerate quickly.
Gears skipping and shruddering between 2nd and 4th gear. Chevrolet dealership recommended engine mounts replaces which was a false diagnose. After further inspection and diagnosing, they revealed that my transmission needs to be replaced for 6200$. I paid the 6200$ and now transmission shifting hard into 2nd gear.
