You have a lemon, sell back to toyota. My advice is based

on statitics from multiple sources, reviews, forums. Please visit edmunds.com, Tundrasolution, consumer report, C&D, etc. Read and research, before and after you buy a car.

Personal experience is biased, the worst car may have extremely happy owners.

For my experience, the only thing i did to my 02 sequoia is change an O2 sensor by myself, which I later found was covered by a TSB.
