2006 Hummer H3 electrical system problems

“Theses templates dosent recognize the key and kicks on the security system which stops the motor from turning on. So you are stuck for 10 minutes then you can try again all so sometimes the motor tries to turn on by just sticking the key in the ignition before you even turn it. By looking at youtube alot of the H3s and the Colorados do this”

“On the electrical, I refer to my air conditioning and heater. When I have my air selection to coldest and I drop 1 click for it to be less cool, my heater turns on and at times it smells like something burning. I have to turn it off . On the engine, after I hit 90,000 miles, I have to fill up my engine oil every 2-3 weeks because my vehicle is burning it quick or something. It doesn't leak oil at all. The oil just seems like it's burning somewhere and I ha e to be waisting money to buy oil $30 to $60 a month. Please help. Thank you!”

“THE H3 WILL NOT START. DASH SCREEN KEEPS SHOWING THE PASSLOCK ACTIVATED AND WON'T TURN OFF. COMPUTER THINKS THE H3 IS BEING STOLEN. I HAVE TRIED TO RESET AND NO LUCK. I HAD THIS PROBLEM ABOUT 4 WEEKS AGO AND CHANGED THE FUEL PUMP. THEN IT HAPPENED AGAIN LAST WEEK AND NOW ON 28 MARCH 2020. ENGINE IS TURNING OVER AND ELECTRICAL SYSTEMS LIGHT UP, BUT SOUNDS LIKE FUEL IS NOT GETTING INTO THE FUEL PUMP AGAIN. AFTER DOING SOME RESEARCH, FINDING OTHERS HAVING THE SAME PROBLEM. RECOMMENDED PROCEDURE IS TO WAIT 10 MIN, STILL NO LUCK. WAITING 15 MIN SEEMED TO WORK BEFORE, BUT NOW IT DOESN'T. HOW AM I SUPPOSED TO BE SAFELY IN THE VEHICLE, DRIVE SOMEWHERE AND THEN IT STALLS AGAIN? I AM THE ORIGINAL OWNER AND HAVEN'T HAD THIS ISSUE UNTIL IT STARTED 4 WEEKS AGO. WHAT IF THIS HAPPENS WHILE I AM DRIVING ON THE HIGHWAY AND FUEL STOPS GOING TO THE PUMP? THIS COULD CAUSE A MULTI-VEHICLE ACCIDENT.”

“I GO TO STOP TRACTION CONTROL STABILIZER GOES OUT, I ALSO HAVE BEEN HAVING TO BUY NEW BATTERIES AND CARRY A JUMP BOX THE CAR IGNITION DOESN'T GO OFF ALL THE WAY. YOU WILL COME BACK TO THE CAR WITH THE RADIO PLAYING, DRIVERS WINDOW STOPPED WORKING, ETC”

“THE PADLOCK SYSTEM THAT THE CAR HAS IT PREVENTS THE CAR TO START AND LEAVES YOU STOPPED FOR 10 MINUTES. IT'S BEEN DOING IT LATELY MORE IN THE MORNING OR WHEN THE CAR HASN'T BEEN MOVED IN AWHILE. THE SECURITY ICON IN THE DASHBOARD BLINKS WHEN THE PASSLOCK SECURITY ENABLES AND THAT LEAVES THE CAR WITHOUT STARTING.”

“MY H3 HAS BEEN HAVING ISSUES WITH RANDOM WARNING LIGHTS APPEARING. OFTEN MULTIPLE LIGHTS LIKE ENGINE, CHECK TRANSMISSION AND TRACTION. EACH TIME I WOULD TAKE IT TO MECHANIC AND WOULD NOT FIND A PROBLEM ANYTHING IN ENGINE. THEN THE 4 WHEEL LIGHT DRIVE WOULD NOT ILLUMINATE. THE MOST RECENT PROBLEM IS MUCH WORST... WHILE THE CAR WAS NOT RUNNING THE RIGHT TURN SIGNAL CAME ON BY ITSELF. I GOT IN IT TO DRIVE IT TO LOCAL MECHANIC AND WHILE DRIVING IT ACTIVATED THE BRAKE AND MANY WARNING LIGHTS WERE FLASHING AS WELL. VERY DISTURBING. I HAVE OWNED THIS VEHICLE SINCE 2006 NOW IT HAS 125000 MILES. I HAVE KEPT A COMPLETE HISTORY OF MAINTENANCE THAT INCLUDES OIL CHANGED EVERY TIME BETWEEN 3500-5000 MILES”
