When I picked mine up in March, the CEL came on 7 miles from the dealer on my way home. Turned around an went back, they thought they had it fixed and sent me home. I made it about 17 miles and it came back on. Called them and set up an appointment for the morning. Turned out to be a faulty O2 sensor, they filled me up with fuel for the trip home, ( I am 70 miles for the dealership ) and sent me on my way. I am at 7,000 miles now with out any sign of a glitch since.
