Yesterday night while coming back from picking my car up from the dealer for an oil change, my check engine light came on out of the blue while driving on the highway doing about 50mph. I took it back to the dealer to see whats the problem, and they said the O2 sensor went bad after only 9000 miles. Anyone else have this problem?

 

Yikes...no...I'm assuming it was covered by warranty though?

 

yes it would be under warranty.
But funny thing happened, i drove the car on the highway for about 50 miles today and the light just went away!

 

Anyone happen to know how many sensors we have in the G?
I had an SHO that had like 12 or 13 and finding the bad one was a real PIA!
