Big Problems here, tonight the check engine light came one(less then 3800 mi.), all stock except for the lux nav (highly doubt the problem), just driving normal and it came on. This happen to anyone else????? Im gonna bring it to the dealer in the morning to see what codes popped up...:wtf1:

Mine did the same thing at 1500 miles. Neighbor suggested checking the fuel cap. Bingo, it wasn't quite tight enough as after a one forth turn more the check engine light went off and has not come back in 10,000 miles. I got lucky.

Well I went to the dealer yesterday, and they said the same thing, check your fuel cap. I said i filled up about a week ago, and that isn't it. So I finally convinced them to hook it up and pull some codes. One code was something to do with the "wait to start light", and the other code was something to do with the check engine light. They aren't able to work on it for 2 1/2 weeks, so we'll see what happens...

Well the code that came up was P0650, the dealers fix to the problem was to change the gauge cluster. Doing this they transferred the original mileage to the new cluster, but they didn't put in the hours. :mad:

So now there is no check engine light, but now every once and a while the display on the bottom doesn't light up.

Time to bring it back again...
