yeah, Travis, I've never had anything going wrong with a gas cap either...and I was raised on Honda and Toyotas. But I hadn't thought of the price of gas, you're right, that MUST be it!

Rick you're right, and I've got to take it in for a few squeaks/rattles making me crazy and I'll have them look into it then. I can't imagine what could possibly caused things to start rattling......
It was a CPO Lexus, and I have a warranty left for about 10 more months....time to use it!
Weird that first cap lasted 5 years, 2nd one lasted 2 weeks.....
