2006 GMC CANYON Engine Problems

The Passlock System intermittently fails and prevents the fuel pump from pumping fuel to the engine. Even after paying GMC to repair the truck, the problem persists.

CRANKS BUT NO START INTERMITTENTLY. GMC DEALER STATES THAT THERE IS NOT PROBLEM. MUST WAIT 10 MINTURES, THEN TRY AND IT ALWAYS STARTS. NOT ISOLATED...GOOGLE, 2006 CANYON WON'T START AND THERE ARE MULTIPLE DESCRIPTIONS OF THE SAME PROBLEM. SOME HAVE SPECULATED THAT IT IS A 'RELAY', PROBLEM WITH THE IGNITION SYSTEM OR THE "PASSLOCK". I AM NOT AWARE OF ANY ACCIDENT BUT IF AVOIDING AN ACCIDENT AND IT WON'T START IT IS JUST A MATTER OF TIME. THIS HAS BEEN AN ONGOING PROBLEM FOR AT LEAST 3-4 YEARS, OCCURRING AT LEAST ONCE PER MONTH. OTHERS RECORDED THE SAME HISTORY.

I BOUGHT THIS 2006 GMC CANYON IN DECEMBER OF 2011. YET THEY MYSTERIOUSLY COULDN'T GIVE ME TAGS FOR IT UNTIL APRIL 2012. THEY KNEW THERE WAS AN ON GOING RECALL FOR BAD VALVE SEATS AND SEALS AND SOLD THE TRUCK TO ME ANYWAY. I IMMEDIATELY BEGAN HAVING ENGINE PROBLEMS AS SOON AS I GOT IT AND HAD THE TRUCK BACK TO MOTOR CITY GMC HERE IN BAKERSFIELD, CA. THREE TIMES UNDER THE LIMITED 10,000 MILE WARRANTY MISSING THREE DAY'S OF WORK EACH TIME. EVERY TIME THEY NEVER DIAGNOSED THE PROBLEM AND TOLD ME ALL THREE TIMES, 'WE HAD A SERVICE ADVISER DRIVE THE TRUCK AROUND AND COULDN'T FIND ANYTHING WRONG WITH IT.' AND YET!!! AS SOON AS THE 10,000 WARRANTY WAS UP THEY SUDDENLY WILL BE GLAD TO DIAGNOSE THE PROBLEM FOR OVER A HUNDRED DOLLARS. HOW CONVENIENT. NOW IT WILL COST OVER $3000.00 TO FIX THIS TRUCK THAT THEY...

THE 2.9 4 CYL. ENGINE IN MY 06 GMC CANYON DIES INTERMITTENTLY. WHEN IT DOES, "REDUCED POWER" DISPLAYS IN THE DRIVER INFO CENTER AND THE TRUCK WILL NOT RESTART. THE POWER IS CUT TO THE STARTER AND FUEL PUMP BUT ALL ACCESSORIES STILL FUNCTION PROPERLY. AFTER A FEW MINUTES THE SYSTEM SEEMS TO RESET AND THE TRUCK WILL START AND OPERATE NORMALLY. UNTIL THE NEXT TIME IT DECIDES TO GO OUT. I WOULD SAY THAT UNDER NO CIRCUMSTANCE SHOULD AN ENGINE DIE UNEXPECTEDLY ON THE HIGHWAY OR AT A RED LIGHT AND NOT ALLOW RESTART FOR SEVERAL MINUTES. THIS IS EXTREMELY DANGEROUS. *TR

CHECK ENGINE LIGHT CAME ON, I USED A CODE READER AND P0300 CAME UP. I REPLACED THE APPROPRIATE SENSORS AND RESET IT. TRUCK RAN FINE. ONE WEEK LATER THE CHECK ENGINE LIGHT COMES ON AGAIN AND THIS TIME I GET A P0017 CODE. I REPLACED TWO OF THE SENSORS AND REPLACED OIL FILTER WITH A OIL CHANGE. NOW THE TRUCK IS HARD TO START AND WHEN IT DOES START IT IDLES ROUGH. I HAVE IT IN THE GARAGE RIGHT NOW AND MECHANIC DOESN,T KNOW WHAT IS WRONG WITH IT. FROM WHAT I HAVE BEEN READING ON HERE THESE ENGINES IN THE CANYON AND COLORADO PICK-UPS ARE BAD ENGINES THAT WONT LAST. I HAVE THE 4 CYLINDER ENGINE WITH 53 THOUSAND MILES ON IT THAT I BOUGHT USED WITH 19 THOUSAND ON IT. I FEEL GMC SHOULD FIX THESE MOTORS FOR FREE EVEN THOUGH IM NOT THE ORIGINAL OWNER AND THAT...

ENGINE WILL CRANK BUT NOT TURN OVER. UPON MULTIPLE ATTEMPTS THE ENGINE WILL GET CLOSE TO TURNING OVER AND THEN CUT ITSELF OFF IN THE ANTI-THEFT SECURITY MANNER. WAITING 10-20 MINUTES WILL MOST TIMES ALLOW FOR THE ENGINE TO THEN TURN OVER SUCCESSFULLY. NUMEROUS WEBSITES AND VEHICLE OWNERS, HAVE POSTED COMPLAINTS AND HAD NO REAL SOLUTION, EVEN AFTER VISITING LOCAL DEALERSHIPS WHO TRY TO INVESTIGATE THE SOURCE OF THE PROBLEM, WITH NO ONE SOLUTION OR FIX. OWNERS TRY TROUBLE SHOOTING THE PROBLEM THROUGH SENSORS, KEY WEIGHTS, BATTERY CONNECTION, AND THE THROTTLE BODY, ALL WITH NO FIX AND CONTINUING RANDOM RECURRING INCIDENTS. THE SAFETY ISSUE OF THIS COMPLAINT IS THAT YOU ARE LEAVING DRIVERS IN A POTENTIAL STRANDED SITUATION. *TR
