I have A 2021 Challenger SXT 3.6 V-6. On start up if the parking brake is applied there is a “thunk” from the drive train. Without checking anything on the car the lame dealership gave it to Chrysler who is claiming that that’s normal. I beg to differ. So, I would like to hear from any members who own a 2021 only SXT Challenger and do they have this start up noise. Thanks. Bill Sebastian FL
