2009 Toyota Tacoma Engine cooling Problems

“I have 2009 Toyota Tacoma double cab 4x4 v6. I also had 2008 model of the same vehicle. Both these vehicles shared a common negative characteristic. The engines have sudden RPM increases that are significant enough to propel the vehicles forward. This usually occurs while the vehicle is stopped and the transmission is in the drive position , at a red light for instance. Additional pressure must be applied to the brakes to maintain control of the vehicle. This problem was identical on both tacomas.”

“While stopped at a red light and crosswalk waiting for two pedestrians to cross my 2009 Toyota Tacoma sport began to attempt to accelerate on its own. The only way I was able to stop it was to put the automatic transmission in neutral - with the engine racing out of control until I managed to turn the ignition key off. My vehicle has about 10k miles on it. Luckily I was able to keep the brake on hard enough to prevent hitting the pedestrians while my tires were smoking because of the engine revving.”

“My 2009 Toyota Tacoma has a demented mind of its own when it comes to unexpected acceleration. I will describe what it has done at least 10 times in the year and a half since I (unfortunately) purchased it. As I take my foot off the accelerator and apply it to the brake, the engine speeds up to more than 7,000 RPM. I continue pressing on the brake which starts to slip. To avoid a crash I must quickly shift the transmission into neutral. As the engine reaches maximum RPM's, it then dies back to an idle. It is not the floor mat or the acceleration pedal causing this. …”

“While driving my 2009 Toyota Tacoma sport pick-up truck in a lowes home improvement center parking lot today (11/27/10 at 2:25 pm), my Tacoma began a very rapid acceleration as I put my foot on the brake to slow down rounding an isle turn in the lot and preparing to park the vehicle. I applied immediate heavy pressure on the brake since a Toyota prius was right in front of me and I did not want to hit it. During my braking the rear tire(s) was spinning and screeching on the pavement. The truck moved forward about 5 feet and then the motor shut off as I was reaching to turn off the ignition. …”
