I have a 2014 Enclave. No problem for the first year, then suddenly I can not put gas in the tank as the nozzle keeps cutting off. Took it in and they found a problem with the vapor recovery system. Replaced it all. worked fine for 2 months now doing it again. Took the car back in and they replaced the entire fuel tank. Did not fix the problem - still keeps shutting off the fuel nozzle. The only thing they have not replaced is the filler line from the gas cap to the tank. When the dealer contacted the "engineers" at corporate they basically said in essence "not our problem, must be the gas stations". Still in the shop and I cant get any more info from them. VERY frustrating, am ready to go to a lawyer and invoke the California Lemon Law. Anyone else have a similar problem??
