I own a 2003 HCH with CVT, (VOLTRON), with 74,197 miles; it went to the dealer with the check engine light on and turned out to be the Oxygen Sensor was bad. I had also been noticing the CVT was making an off idle vibration and was told the the off idle clutch in the transmission was going bad. Needless to say the dealer was very nice in ordering me a new transmission and O2 sensor while letting me drive my car; they even gave me a free oil change while checking the engine codes. I sure am glad I got the 5 year 100,000 extended warranty. By the way I've had the CVT fuild change at the dealer three times; every 15,000 miles. Will let you know how it all turns out next week. Mileage has suffered by about 5-8mpg with a bad O2 sensor.
