2020 Chevrolet Impala UNKNOWN OR OTHER

As I was driving my car in the interstate the car started making noises and began to shake and then it stop driving normally. I did my best to move to the curve and then called a towing truck to get the car. The car transmission stopped working properly. I conducted an analysis on this car in the internet and it has been written that the transmission has a manufacturer's defect. Also, the car dealer did a diagnostics test on the vehicle and proved that the transmission is not responding. The car dealer said the repair is not covered. This car is less than 5 years old. I was driving with an unsafe car. Data indicates that the transmission defects with a transmission fluid leak. I was in a dangerous situation while driving the car in the interstate. There were no warning signs and I believe this can be a dangerous situation for other consumers who may have the same car. The dealer and manufacturer does not want to cover the repair of the transmission since they said there has not been any recalls with the car. I want to put this complaint because I was at risk for something I had no control of. I contacted the corporate office and they told me to take it back to get a second diagnostic. In my opinion I have already done the diagnostic and they will not accept it unless is recent. The diagnostic was done in March 2024. Dealer wants me to pay for the repair. The transmission fluid leak is a problem that appears to be from the manufacturer because a transmission's life should last longer. The car has been undriveable.

While driving the RPMs decrease while the speeding is increasing. At time you can feel the car slow down when pushing the accelerator and then it slightly jumps forward. The car can be going 75mphs and the RPMs will be between 0 and 1. This also causes it to lag.
