I purchased an Mazda MPV in 2007 from a Chevy dealership who said it was in good working condition. It was a 2000 model. As soon as winter came the O2 sensor on the rear bank went out. Paid $400 to the dealership to replace. It lasted only a short time. The dealership told me it should last 100.000 miles, so they replaced it and only charged me another $400. To date I have had the O2 sensor replaced a total of four times. The last two times it was at a Mazda dealership. They also told me it should last 100,000 miles. But every time it gets below 40 deg F, it fails, or at least the warning light comes on. I have spent a total of $1,200 in replacing the sensor. I keep doing it because my wife uses it to drive our granddaughter to dance class and I don't want them to get stranded on the road way. I have already lost my aunt's daughter to a road side killer and don't want it to happen once more.

An open seam in the consumer's 2000 Mazda MPV's front exhaust manifold allowed exhaust fumes to enter the vehicle. The consumer's child had a severe asthma attack as a result of this failure.
