I drive a 2009 GMC Canyon. When driving I've notice that when hitting a hard bump, sometimes turning or accelerating quickly whether on the highway or street, the truck shuts off causing the power steering and power brakes useless and very hard to apply. Sometimes this happens several times in the course of one trip and happens at a variety of different speeds. This is an ongoing problem. The icon for the theft deterrent appears. Then I have to quickly put the truck in neutral in order to restart the truck. The date below is the most recent day it has happened. This has become a very serious cause of concern for me and my family. I'm not sure if this is related to the ignition recall or any other recall. This problem happens mostly when I hit a hard bump in the road, again at various speeds. I've taken it to my mechanic, but he was unable to duplicate the problem. I've decided to ask the dealer if they know of any related problems and see what response I get, but I also wanted to file a complaint to find out if anyone else is having this issue. If you are aware of any other complaints related to this issue, can you please contact me so that I may resolve the problem. I don't want to take this issue lightly because the life of my family is involved. If you have any other questions please contact me, my name is [xxx] and my phone number is [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I sent in this complaint a year ago and never heard back from you. Throttle sticks on my Canyon and it appears to be computer related. It continues to accelerate even after taking my foot "off the gas." It will rev down after hitting the brake pedal. Have you heard of this before? truck is standard shift and usually happens when "going through the gears".

This incident has happened on several occasions. When taking off from a stopped position and going through the gears when accelerating quickly, the accelerator has stuck even when my foot is taken off of the pedal. This happens as I am shifting from first to second gear, when I take my foot off the gas then push in the clutch and shift gear and release the clutch, the computer does not respond to my foot coming off the throttle. The truck continues to accelerate even with my foot off of the throttle. The only way to stop the acceleration is to repeatedly tap the pedal until it releases. The first time this happened I thought that I might have inadvertently hit the cruise control but this is not the case. It seems that I need to allow approximately a one second delay from when I remove my foot from the throttle until I push in the clutch to avoid this situation. Is this typical of today's computer controlled vehicles?
