Oxygen sensor failure, 33k miles
 

2005 HCH, a little over 33,000 miles. Just tossing out an FYI. Thursday night driving home the "malfunction indicator light" came on. I was due for an oil change on Saturday anyways, so they looked at it and said the oxygen sensor had failed. I'm out of the standard warranty (I've had it 3.5 years), but all the work & parts were covered under Honda Care extended warranty.

I haven't had any other maintenance issues, this was the first time I've had to have it in.
