On several occasions spanning multiple years the truck loses power while braking and turning at slow speeds. On more rare occasions, but still numerous, the same problem occurs when braking at higher speeds without turning. The truck dash lights, media screen and headlights all dim or flicker as a ticking or popping noise is heard behind the dash much like an arching electrical wire. Most of the time when these scenarios happen the display on the drivers display screen reads stabiltrak warning. Also when the problem occurs while turning and braking at low speeds the truck will completely lose power and power steering as well as assisted braking. Once the truck comes to a stop the ignition, and all electrical systems are completely unresponsive like the battery is dead. In order to start the truck again, I have to get out of the truck, open the engine hood and oscillate both the negative and positive battery cables. Most of the time the truck will start up after doing this. Sometimes I have to use booster cables to get it to start. Neither the cables or the terminal connectors are loose as they have been inspected by a dealer service tech and a local mechanic.

- Halstead, KS, USA

Was in driveway, started the car and then put foot on the brake to shift into drive. As soon as I was in drive I began to roll forward even though my foot was still on the brake. I then had to really step on the brake (it was very hard to apply pressure) to get it to stop rolling. I then immediately placed it in park. This happened several more times throughout the day, only at low speeds, or when switching from the parked position to drive or reverse. This is extremely dangerous when trying to park (child could be injured in driveway) or slowing down in a parking lot or could cause a collision in traffic!

While exiting highway I attempted to come to stop and my brake pedal was extremely stiff and I had to put hard pressure into brake to come to a complete stop before rear ending the vehicle in front of me. Luckily, I was able to stop before a collision occurred. I was able to get to my destination on city streets, but my brake pedal remained extremely stiff. I was very close to causing multiple accidents due to this brake issue.

Some time traveling between 60-70 mph the truck has a vibration or something, but if I tap the break pedal it stops. I've had this four times on the interstate. Took truck to the dealer, they found no code listed. Just this weekend as I was exiting the interstate ramp to I-71 South the truck was slowing down and I had pull off the interstate. It was as if the braking system was being applied, truck would not move. Break pedal was very hard to press. I turned the truck off for a couple of minutes and restarted, pedal was still very firm but after pumping pedal, I heard this sound like you were passing gss yourself and then the petal was back to normal. I was lucky that this did not cause a wreck as my speed was being reduced to a slow speed having to pull on interstate.
