2009 GMC Canyon Powertrain & Transmission Problems

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].

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". *TR

WAS DRIVING SLOWLY IN A PARKING LOT AND WAS STARTING THE TURN INTO A PARKING STALL WHEN THE STEERING BECAME VERY DIFFICULT AND THE VEHICLE HAD DIFFICULTY MOVING FORWARD. TRANSMISSION HAD GONE INTO 4X4 LOW WITHOUT ANYONE PUSHING THE BUTTON ON THE DASH. I HAD A 2007 CANYON AND IT DID THE SAME THING ABOUT 3 TIMES WHILE DRIVING IN A PARKADE. WHEN I CONTACTED THE DEALER THERE COMMENT WAS TO BRING IT IN WHILE THE INCIDENT IS OCCURRING. WHEN I DID TAKE THE 2007 IN FOR SERVICE THEY COULD NOT FIND ANYTHING. I WILL MENTION THE INCIDENT ON 2009 WHEN IT GOES IN FOR ITS NEXT SERVICE. *TR

TL* THE CONTACT OWNS A 2009 GMC CANYON. WHEN SHE SLIGHTLY STRUCK THE GEAR SHIFTER AT 20 MPH THE GEAR SHIFTED FROM "DRIVE" INTO THE "REVERSE" GEAR. SHE WAS ABLE TO REGAIN VEHICLE CONTROL. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR INSPECTION. THE TECHNICIAN COULD NOT IDENTIFY THE CAUSE OF THE FAILURE. THE FAILURE MILEAGE WAS 3,400. THE CURRENT MILEAGE WAS 3,700.
