Open the full vehicle complaint log (all categories)Went in for a typical servicing. They noted that the downstream O2 sensor was damaged by rodents. The vehicle, with around 14k has always been stored in a weather tight garage, never stored outside. There has been no rodents in the building since I owned it from 1999. This is a presumptuous statement I refuted, but they wouldn’t take off, and I felt this is a warranty or recall item. There are lots of speed bumps in the North Portland neighborhood, which may have caused the problem by cable scraping. I believe they documented it as rodents to escape their extended warranty contract requirements. I purchased an O2 sensor, which my independent said I don’t need to use it after taping the scrape as there’s no electronic issues being reported in the system. I would like this investigated and them pay for the sensor I apparently don’t need to install.
