“I am filing this, my second, complaint about my 2009 Toyota 4runner. My first complaint was filed in february 2010. I complained to my dealership about the problem since right after purchasing the 4runner which we bought brand new in may 2009. The problem occurred when slowing down to turn corners to about 15 MPH, and then stepping on the accelerator to speed up, the car revs, sometimes 2500-3000 rpms before the transmission engages and we lurch forward. …”
NHTSA complaint #10356674, filed 2010-09, 3,500 miles“I purchased my 2009 4runner new last year. From the minute I drove it off the lot I noticed a problem with the transmission. Any time the vehicle slows below 15mph and then the accelerator is depressed, the engine revs to a high RPM as if searching for a gear and does not accelerate as commanded. This is very prevalent in slow traffic, slowing for a yield sign or turning corners. The biggest safety concern is in slippery road conditions. When the vehicle finally does find a gear to shift into, it lurches forward. …”
NHTSA complaint #10373627, filed 2010-12, 1 miles“My granddaughter was driving a 2009 that I bought her for graduation in may 2010. In june 2010 she and some friends were driving and a fire started in the console area. There were flames and smoke. They stopped the car, went up to someone's house and got water to pour into the car and put out the fire out. If they hadn't been quick thinking, the car would be toast. Also, if they had wrecked and could not get out of the car, they would have had severe burns or death. We want the car fixed under warranty rather than our insurance. …”
NHTSA complaint #10348546, filed 2010-08, 23,000 miles“When my wife stepped on the gas to pull into a parking spot,the 4RUNNER just lurched forward into a fence. Luckily no one was in front of the 4RUNNER. The bumper and fence was damaged. She is now very scared to drive the 4RUNNER.”
