Less than 2000 miles on it. Parked for 1 month then the check engine light came on immediately after startup. Drove fine. Tried 2 OBDll devices and one wouldn’t link up while the other would start then error out. Before I take it back to the dealer, cleaned the gas cap seal and put some wd40 on it. Will drive it a bit and hopefully the check engine light will clear. Any suggestions?
