GenVibe - Community for Pontiac Vibe Enthusiasts

Brought my 2003 Vibe into dealer with CEL. The code was P0420, and after a thorough check, they replaced the catalytic convertor. So far so good, and best of all - NO CHARGE !

Cat below threshold?either way cool you got it fixed for free.

Yep - but you can't tell very easily whether it is the cat or O2 sensor.

Were you under the GM warranty or was this done under the emissions warranty?Glad they took care of it!

his first post says he took delivery on April 27, 2002, so the factory 3 year warranty has been gone by a year and a half, I'd bet the emissions warranty.I had passed the mileage on the emissions warranty when I had to replace mine. Easy enough to replace, but the part is expensive, so getting it done at no cost is great.

Good detective work ! You're right, the car is 4 1/2 yrs old, and 66K miles, so the emissions warranty covered it. The odd thing is that the O2 sensor is NOT covered past 36K miles. Had it been that, then i would have had to pay $85 for diagnosis, plus the replacement for the sensor - so i lucked out big time !
