Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
