Heres one for ya !!!!
 

I have an XG350L 7 months old just turned 4,000 miles, pulled in driveway
this AM and CHECK ENGINE light comes on !!!!! I checked gas cap ( always
turn it 9 or 10 clicks when I put it back on ) and it was fine... Any other
ideas on such a NEW VEHICLE ??

P.S. Already called dealer and have appointment for Friday morning.
