I'll add my story here as well. State: PA
Bought a P3D in August '18. Had repeated issues with the safety restraint system (4+ visits) amongst other things (6 other visits). I finally asked for a buy back in July 19' (23k miles, first restraint issue at 11k) took two weeks to process. They offered full purchase price + tax (No FUSC rebate deduction, No Tax credit deduction, No mileage offset). I turned the car in on August 1 and got the check 8 days later.
Currently have another P3D ordered waiting on a VIN.
As a side note If they didn't give me a reasonable offer I was going to file an arbitration claim and had a solid case because in PA it fulfilled all of the lemon law qualifications.
