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.

problem #2

Aug 072009


  • 90,000 miles


The vehicle rpms would go up but the car would barley move, or while driving going to accelerate the vehicle would not go faster to engage in traffic, corrosion of pins in the transmission wiring harness that connects to the engine wiring harness. This harness is also tied to the ABS, traction control. It causes the vehicle to become unsafe when driving as if it acts up you cannot accelerate and sort of chugs along. Dangerous in on ramp and traffic situations. This also caused the solenoid in the transmission to short out as it was hanging up on the shift which caused a clunking sound. The transmission wire harness was replaced which showed 3 corroded pins. The solenoid in the transmission was also replaced.
