In owners' own words
Toyota knowingly uses a soy based wire coating that attracts rodents. Something chewed through the wiring harness making my vehicle shake uncontrollably and act very strange. This is a huge safety concern because what if the damage was only partial and then through normal use like highway driving the wire fully comes apart disrupting any and all safety features Electrical system · reported at 12,000 miles
Door lock/unlock actuators are going out. Driver's side and now front passenger's side. This appears to be a prevalent issue on line, and nothing has been done. Replacing one costs $550. Electrical system
Wiring harness to rear window defogger melted causing the rear window to crack and shatter. Safe lite replaced the window and recommended the harness not be reconnected. Told me it was not uncommon. Vehicle was not being used at the time. It was in my driveway when the window blew outward. Inspected by Safe lite, Reported to Liberty Mutual. No warning light, rear defogger was not in use, car was off. Visibility/wiper
