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.

2009 Toyota 4Runner Owner Comments

problem #1

Sep 152010

4Runner 6-cyl

  • 79,800 miles


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. Now, 17 months later and many trips and E-mails to my dealership, who can't get a response from Toyota that makes sense, and my 4runner still exhibits the same problem. My husband had a kidney transplant in August 2009, which requires travel to a big city about 90 miles from home several times a month, that has heavy traffic flow. Last week, I had to make a quick acceleration to merge into oncoming traffic, and for the first time, the 4runner actually did the same thing it does on turns. When I stepped on the gas to merge into oncoming traffic, the 4runner just revved for a few seconds and then lurched forward into traffic. Luckily, no accident resulted, but we were very scared. I participate in forums on different car sites and there are many of us having the exact problems and yet Toyota has no answer or puts us off with some lame explanations or worse, tells us that is just the was the 4runner is because of the computer. My dealership has reset the computer and did not remedy the problem. I am reporting this newest incident for documentation in case this problem actually causes an accident, my complaint will be on file. Thank you updated 09/28/10 updated IVOQ 09/29/10
