Check engine light comes on and want go off, disconnected battery went away, until filled the car with gas again. Came back on.
After filling up with gas...about an hour later service engine light came on
2005 SRX V8 AWD engine light came on after a fill up and noticed the gas cap felt loose (not ratcheting to a tight fit) After looking at various website threads I made mistake of buying a generic Stent brand cap. Not only didn't the rubber tether fit this cap but engine light still on. Ordered the correct cap from gmpartsdirect.com, installed and engine light went out within 10 miles of driving.

Engine light comes on/off for the last two years that I owned it.
