What component or system failed or malfunctioned, and is it available for inspection upon request" Car will periodically and unpredictably not crank, fire or start. After attempting approximately 10 minutes later it will. How was your safety or the safety of others put at risk? One never knows circumstances in which they need reliable transportation. In my case I have elderly parents that can need me at any given time. In most cases it is an annoyance but due to the unpredictable factor anything could happen. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes but no codes were trapped in ECM Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear"

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).

For several months now, vehicle will not start. Turn key, no click, no crank, nothing. All standard dash light come on, headlights are bright, all accessory items work fine, just no start. Have taken truck in to dealership twice now for problem, and no resolution. Starts every time for them. Last time took key and paperwork, went out to lot, got in, and no start, went back in to dealership, finally grabbed mechanic, went to truck, but it started ok. May not fail again for a day or more, then fail several times in same day. Failed to start today after pulling into gas station and getting fuel, would not start. Long line of cars behind me and situation got very ugly fast. Station owner/worker helped diffuse situation. If you let vehicle sit for 10-15 minutes between retries, it may start.

We were at family gathering when a neighbor called and said the black truck is on fire. I rushed out the door to investigate and there was a fire inside the cab on drivers side in rear section. I started spraying it with a water hose and called 911. The fire department came extinguished the fire and filled fuel tank with water just in case they said it looked like something electrical started the fire in that section of the truck. Fire marshall going complete investigation and insurance was called.

Anti-theft system would not allow the truck to start, then once started the entire dashboard components failed no speedometer, fuel, temp or air conditioner would work, also the traction control went into alarm... GMC people said they could not see any alarm codes and failed to repair the anti-theft system... recommended I get on-star to help identify the problem.. I did, it failed again and on-star saw the codes however GMC says they cannot trust on-star findings, even though they recommended them which is costing me $30 a month to monitor their vehicles warranty.. still driving a truck that sometimes does not start and the entire dashboard shuts down while driving... very dangerous.
