I've had a check engine light come on for a second time while towing. Here is the scenario: Doesn't come on until second or third day. Running 65 mph plus or minus. Both times it came on after a very long gradual uphill pull of 50-75 miles at altitude.
First time I found a local NAPA store that was able to pull a code saying air fuel mixture bank 2. He didn't have the updated software to give me the number. Both times it has cleared after unhitching and driving for a while. Talked with selling dealer the first time and he said it was probably a software bug and not to worry. Anybody got a clue?
