“I am filing 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 #10356677, filed 2010-09, 79,800 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.
