Notes: Although it has a stellar record in terms of vehicle problems, initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

Highway merge ramp at almost full throttle twice, once passing another vehicle on highway at also high throttle usage, accelerator pedal was stuck open vehicle continued to accelerate felt like cruise control was engaged but wasn't. I stepped on brakes but that didn't help, I then hit the accelerator pedal with my right foot and the pedal went back to normal.
