Description of the problem | My 2013 toyota tacoma 4 cylinder truck, while in motion, intermittently accelerates, without warning, for a few brief seconds then correct it self. This acceleration happens without the driver initiating the acceleration by pressing on the accelerator. This has been happening for about 1-1/2 years. For approximately the past 4 months (july - nov 2016) the engine revs up to higher revolutions, immediately after engaging the ignition, while still in park. It's as if i was deliberately pressing on the accelerator immediately after starting the engine, while it was still in the park position. In fact i had not pressed on the accelerator. When i had it checked out, i was told that's the way toyotas start. It was after the truck began to bolt/accelerate at a high speed after going from a park position to either a reverse or drive position, immediately after releasing the brakes, and not pressing on the accelerator, the week of october 25, 2016 that i reported the issues to the toyota customer care experience center, in plano, texas (case numbers: 161 027 1958 and 161 110 2063) . Ballentine toyota, in greenwood, s. C. Inspected the vehicle and drove it about 300 miles and reported to me that no problems were found. After getting the vehicle back nov, 4, 2016, nothing happened for awhile, then on nov., 9, 2016 it would not allow me to accelerate for a few seconds after driving about 9 yards. The first time the truck did not allow me to accelerate was on oct. 25,2016, when i attempted to accelerate to 55 mph. After about 20 miles i was finally able to reach 55 mph. On nov., 10, 2016 the truck bolted/accelerated as i attempted to leave a parking lot while out shopping. I left it in the parking lot at the store where i was shopping. It remains there as of this writing november 14, 2016. Updated 06/26/2017*js |
