2014 Toyota Tundra Vehicle speed control Problems

“I was on the highway (not using cruise control) when my check engine light came on and the throttle control changed. The truck would randomly throttle without pushing on the pedal. Additionally, if I put the pedal down the truck couldn't get beyond 60mph going up a hill.

“Vehicle accelerated when taking foot off gas (engine revved) and accelerated on its own causing vehicle to spin out during winter driving conditions and sent vehicle smashing into cement barrier. Vehicle has accelerated on its own since driving off lot in november, 2016. At first I thought this was an issue with the four wheel drive, but it's clearly an acceleration issue. I've also tested this and was able to make it nearly 1.5 miles from my home, mostly up hill without even stepping on the gas.

“The contact owns a 2014 Toyota Tundra. While the vehicle was idling at an intersection with the brake pedal depressed, it accelerated without warning. The contact placed the vehicle in neutral and then in park. When the vehicle was turned off and restarted, the failure recurred. The contact installed a new battery, but the failure recurred. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and informed the contact to bring the vehicle in for diagnostic testing. The failure mileage was 28,000.”
