2007 GMC Canyon Powertrain & Transmission Problems

VEHICLE CRANKS BUT DOES NOT START. SECURITY LIGHT FLASHING. AFTER 10 MINUTES WITH KEY ON AND SECURITY LIGHT OFF AFTER TURNING OFF THEN CRANK ENGINE STARTS. HAPPENED AT LEAST 15 TIMES. NOW, ENGINE SOMETIMES WILL CRANK ITSELF IN THE "ON" POSITION AND WILL NOT START AND SECURITY LIGHT FLASHING. HAPPENED THREE TIMES AND FINALLY AFTER THREE 10 MINUTE KEY ON WAIT CYCLES IN A DARK PARKING LOT SECURITY LIGHT STOPPED FLASHING AND STARTED AND MADE IT HOME. VEHICLE VERY UNRELIABLE NOW. I AM TIRED OF HAVING A VEHICLE THAT THINKS THE OWNER IS TRYING TO STEAL OWNED VEHICLE. AND AUTO CRANK IN THE ON - NOT START- POSITION WITHOUT RUNNING. HOW DO I BYPASS THIS AWFUL SYSTEM WITHOUT ANOTHER CAR PAYMENT TO ANOTHER AUTOMAKER? THIS DEFECT IS DANGEROUS AND HAZARDOUS WHEN STOPPING FOR FUEL AND HAVE TO LEAVE ENGINE ON OR HOLDING UP CUSTOMERS UNTIL ENGINE STARTS. ALSO HOLDING UP VEHICLES ON A FERRY BOAT. VERY EMBARRASSING WHEN FRIENDS AND CO WORKERS HAVE TO WAIT TILL VEHICLE DECIDES TO START AND RUN. AND BEING LATE TO WORK. I DO NOT WANT NEW PARTS THAT WILL FAIL AGAIN, I WANT IT BYPASSED. SEND ME A KIT WITH DIRECTIONS ASAP! *TR
