My wife drove the vehicle to work one day and when she was pulling out of the parking lot onto a busy street, the yellow triangle with exclamation point started to flash and engaged the brakes. My wife quickly pull over to the side of the street and made her way back into the parking lot while the brakes where engaging. My wife was unable to drive the vehicle home from work. We let the vehicle sit for several minutes and I was able to get the vehicle moving but the brakes were engaging again. I was able to get the vehicle back home. I have taking the vehicle to several shops and all the shops are saying that there is an issue with the traction control system. When driving the vehicle from one of the shops, as soon as I pulled out of the shop's parking lot the brakes engaged and the yellow triangle with exclamation was flashing. It did this for about 15 seconds caused the approaching vehicle from the rear to slam on their brakes to avoid rear ending me. The vehicle has become unsafe to drive because we just don't know if when it does this. It happens randomly usually after the vehicle as been sitting off for a several hours.

While driving, went over bump in road, and truck immediately lost speed. Pressure on gas pedal weakend. There was absolutely no acceleration. I pulled over after almost being hit, and turned vehicle off. Restarted and pull over into autozone to have them hook it up to diagnostic reader. It came back with several codes, that all stated "throttle pedal positioner malfunction" I have bought and replaced this item 4 times since this incident, and the problem still exists. I am forced to drive the vehicle because I have to get back and forth to work, but I'm always very afraid that this part is going to malfunction while in a busy intersection or street, and I along with my kids are going to be killed. It happens at least two to three time a week, sometimes more.
