Finally got an appointment to have my Shelby looked at. Been having a clicking noise(very loud) on the rear passenger wheel well. And a tire the went flat out of no where in 2 hours ok the same wheel. Head mechanic rode with me and heard the noise. They took apart the wheel the entire brake assembly, the rotor, and moved the parking brake line( the said they didn’t like how it was laying and didn’t want it to kink). After all of that they said the don’t know what the issue was and the clicking has stopped. They also swapped the rims to opposite sides. So my point they took the tire off the rim, and it was full of fix-a-flat. Needs a new tire and a new sensor. I bought it used with 3k miles on it from a different dealership and was unaware that it had a hole in it and had fix a flat in the tire. I guess previous owner ran over a nail and didn’t want to pay for a new tire. New rear tire from dealership is $527, new sensor for tire is $164. Questioning if I am obligated to pay or the dealer I bought it from who sold it to me like that should. I’ve had the car for 3 weeks.
