Well, got a CEL and went to autozone, P0420.
Did some searching and came up with the answer (I think) which seems to be either ECU reflash or new catalytic converter. I am well within the 8/80K federal emission warranty.
I call the local dealership and explain, and they schedule me to come in for a $90 diagnostic, explaining that if indeed it is a repair covered under warranty that there will be no charge.
Can anyone give me some input as to what to expect, is there any bogus repairs the stealership could create to hit me with a big bill on this?
Thanks.
