“I was driving on dec. 24th, 2018, turned on my rear defroster on, and within minutes my rear window exploded. The company, safelite, told me that the defroster looked like it shorted out and caused the damage. Attached is a picture of the defroster wires.”

“The rear hatch door handle turned into a melted rubber/plastic mess. Our hands are covered with black melted rubber type material whenever we try to open the rear hatch. After online research, I see there are allot of other Toyota 4 runners with the same problem. The part is called, switch assembly, back part #84840-35010. No doubt that the part is faulty.”

“The rear hatch door handle is deformed and turned into a tar-like mess that covers our fingers whenever we try to open the rear hatch. I have noted numerous other 4-runner owners having the same exact malfunction. Problem is the melted rubber cover which is part of the switch assembly, part #84840-35010. Totally unsat!”

“My rear window shattered after using the defroster. Once I got out of my car after parking it in my job's garage it busted on it's own. I found out that this has happened to many 4th generation 4RUNNER owners but Toyota won't recall or extend the warranty for this issue any longer. Now I have to either never use my rear defroster again while living in colorado or risk it shattering again and hurting passengers in my car. I would have never bought the vehicle if I had knowledge of such a dangerous issue.”

“My vehicle, 2007 Toyota 4runner, has been experiencing some issues when the temperature drops below freezing. Living in maine, this happens more often than any human would like. In any event, my HVAC blower motor continues to literally freeze up and will not work. Toyota has issued a TSB (ac002-07) on this exact issue. Since my vehicle is out of warranty I'm told by the local dealer and by Toyota directly that I need to assume all costs for repair, yet if the vehicle was in warranty these repairs would be covered. …”
