2020 Chrysler 300

I purchased this Chrysler 300 new Nov. 2020 with 6 miles on it, This has been one of the best new cars I've purchased. March 1 2022 At 23,800 miles. I was traveling on KY70 around a sharp curve within advised speed, The car made a loud grinding noise at the gear shift knob under my right arm, The car seemed to be trying to shift gears My hands were on steering wheel and both myself and passenger had our seat belts on with doors closed properly. I drove the car home 8 miles with it grinding at every curve. I called my local dealer and made appointment for repair, Due to car shortage Don Franklin motors 1147 S HWY 27 Somerset, KY service told me that due to work load I would need to bring car in April 27, 2022 at 1030 hrs. I parked car and on 04 27 2022 Turned car over to Franklins service for repair. Mileage on car was 23844. Franklins called me later in day and said they ordered a alternator for it due the noise was from bad bearing. I Stopped by April 28th at 1500hrs and car was ready. I asked about gear knob grinding and was told it was Ok, noise was alternator. I drove away and noticed noise turning out of parking lot. I checked mileage and car still had same miles as it did when I dropped it off. I took back to service advisor and drove out of lot to hear noise he did! Advisor told me that a 10-20 mph the car would be able to control if it went to lock up. I did not agree and needed it repaired, Advisor told me a mechanic would have drive and hear noise and was busy today I was given a appointment of June 16, 2022 at 1030 hours OVER SIX WEEKS more without car! I called 1-800 Chrysler number in owners manual to get option. I got no where with them don't care keep driving until appointment. My Local dealer and service folks don't care to met this car in a curve for next six weeks and they have more car dealerships in all adjoining towns spreading this great service.PLEASE INVESTIGATE problem!
