FUEL/PROPULSION SYSTEM
The fuel level sensor stopped working now it say I’m on E These go out on these cars And are on the recall list, but not on my vehicle yet
NHTSA complaint #11714487 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
I was driving the vehicle at a normal rate of speed and stopped at a traffic light getting ready to change. I applied the brakes and when doing so, I heard some horrible noises and felt certain that parts had fallen out of the car. I knew something was immediately seriously wrong. I put the car in park (but it was effort and a grinding noise to put it in park) and stepped out to look under the car. No parts were on the ground, but something was leaking out of the bottom of the car. I got back in and put the car in drive to move it from the roadway knowing I was going to need assistance to tow it somewhere. It grinded trying to put it in any gear and only "revved" the engine when I tried to apply gas to drive it. There was absolutely no warning. The tow driver immediately noticed the drive shaft was disconnected and that was the leaking and thus going nowhere. My mechanic said that both leaf springs snapped off and that caused the drive shaft to sever, hitting the gas tank (or strap) and some other things. My concern is that there is a recall on leaf springs for every year Hummer H3 except mine as well as 1995-2015 Chevrolet, GMC, and Hummer leaf springs. I'm having a very difficult time with how both of mine snapped with no warning tearing all of these components out and it is not involved in the recall. It is the same parts on all of these. Also, my vehicle has spent the majority of its life garaged, never driven in the snow or rain, as I have babied this car. I have a car wash membership too and constantly keep this car meticulous. Hummer said that enough people need to complain, but I would not even have thought to complain had BOTH not snapped off simultaneously finding the recall for all other years while researching the cost. Had only 1 broke, I wouldn't have given it any thought. And Hummer said that they wouldn't even talk to me unless my car was at a GM dealership. This should be included in the recall. This is not pure coincidence. They need to fix it.

I have the well known issue with the passkey security system. Nothing is wrong mechanically with the car but the security system will not allow the truck to start, therefore leaving me randomly leaving me stranded. Much has been documented on this issue, yet gm has never done a recall.

FUEL/PROPULSION SYSTEM
I bought my 2007 hummerh3 used w/124,000 miles. I've had it a month and already had it in mechanic shop due to not starting. The mechanic thought it was a fuel relay and charged me 258.00 parts/labor/tow. Today 11-16-21, only a day after I got it back, it stopped on me again!! Just had it towed again. Just learning that this is a common problem! Is anything being done to rectify this problem?

FUEL/PROPULSION SYSTEM
THE ANTILOCK SAFETY IS PREVENTING ME FROM STARTING MY VEHICLE. WHEN IT DOES START, AND I GO TO AN INTERSECTION TO TURN THE TRUCK WILL THEN STALL OUT. IT CAN CAUSE A WRECK. IT IS A HUGE SAFETY ISSUE, TIME CONSUMING, AND MONEY CONSUMING WHEN I HAVE TO WAIT 10 MINUTES TO TRY TO START MY TRUCK, OR IT DOESN'T START, I HAVE TO REPLACE IT FOR $450+ WHICH I DON'T HAVE TO REPLACE THE IGNITION SWITCH AND IT'S DANGEROUS BECAUSE IF IT DOES LET IT START I HAVE TO BE CAREFUL BECAUSE IT WILL STALL OUT ON ANY GIVEN SECOND CAUSING A CATASTROPHE!!! THERE ARE MULTIPLE PEOPLE WITH THE SAME ISSUES ON THEIR VEHICLES. GM SHOULD BE RESPONSIBLE TO DO A RECALL AND FIX THIS PROBLEM.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
WENT OUT TO START H3, TURNED KEY, CHECK ENGINE LIGHT CAME ON, THE BATTERY LIGHT CAME ON AND THE ANTI-THEFT SYSTEM LIGHT CAME ON. PASSLOCK/SECURITY SYSTEM INSIDE THE STEERING COLUMN IS BAD. CAR WON'T START. IS UNSAFE AND WILL STRAND OWNER WITHOUT WARNING BY NOT STARTING. GOES INTO SECURITY MODE. WAS TOLD TO WAIT 10 MIN AND TRY AGAIN. CAN'T TURN IT OFF AT GAS PUMP FOR FEAR OF IT LOCKING ME OUT AND NOT STARTING. I HAD THIS HAPPEN TO ME 4 TIMES IN ONE DAY. SO MANY COMPLAINTS ALL OVER THE INTERNET AND PEOPLE TRYING TO FIX THIS ISSUE. THERE IS EVEN A COMPANY SELLING A PART TO BYPASS THIS AND THE SECURITY SYSTEM WHICH AGAIN IS ANOTHER ISSUE. GM IS CLEARLY AWARE OF THIS ISSUE. THIS NEEDS TO BE RECALLED. STRANDING PEOPLE CAN BE VERY DANGEROUS. IF THERE IS AN EMERGENCY AND THE CAR WON'T START. ALL AROUND BAD BUSINESS BY GM FOR NOT ISSUING THIS RECALL. THIS HAS NOTHING TO DO WITH MILEAGE WHICH GM MANAGER SAID ON THE PHONE. THESE H3'S ARE KNOW FROM THIS FRESH OFF THE DEALERSHIP FLOOR. PEOPLE ARE BEING FORCED TO TAKE IT TO A DEALERSHIP FOR REPAIR AND REPLACING THE PART WHEN THE LABOR COSTS MORE THAN THE PART. SEEM LIKE A MONOPOLY FOR GM AND ITS DEALERSHIPS. I HAVE SEEN ANYWHERE FROM 1500-2000.00 TO INSTALL AND RECTIFY THIS BAD PART AT THE GM DEALERSHIPS.

WE JUST PAID 1300.00 TO HAVE THE FUEL PUMP REPLACED LAST WEEK. NOW IT WON'T START AGAIN. I HAVE SEEN MANY COMPLAINTS ON THIS AND THERE SHOULD BE A RECALL ON THIS PROBLEM.

NHTSA complaint #11171159 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
SIR/MA'AM, I AM WRITING TO COMPLAIN ABOUT THE 2007 HUMMER H3 SECURITY SYSTEM NOT ALLOWING THE VEHICLE TO START UNDER CERTAIN CONDITIONS. I MAINTAIN MY VEHICLE TO HIGH STANDARDS AND OVER THE LAST 8 MONTHS HAVE HAD ISSUES STARTING MY HUMMER. WHEN THE HUMMER DOES NOT START, YOU MUST WAIT 10-15 MINUTES TO EVEN ATTEMPT TO RESTART. THE VEHICLE WILL TURN OVER, BUT NO FUEL IS SENT TO THE ENGINE TO START. IF IT DOESN'T START AGAIN, YOU MUST WAIT ANOTHER 10-15 MINUTES. THE LATTER HAS HAPPENED TO ME 5 OR 6 TIMES IN JUST THE LAST 2 MONTHS. THERE HAVE BEEN NUMEROUS COMPLAINTS TO GM ABOUT THIS EXACT ISSUE, AND HAS FALLEN ON DEAF EARS. MANY VEHICLE FORUM USERS COMPLAIN OF THE EXACT ISSUE AS WELL, WITH ZERO ASSISTANCE FROM GM AS SEEN HERE: HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-C8039_DS531571 I AM CONCERNED THAT IF THE SPORADIC SECURITY LOCKDOWN (PASSLOCK) OCCURS WHILE DRIVING, FUEL IS CUT OFF FROM THE RUNNING ENGINE, SPEED/STEERING/BRAKING WILL BE MINIMIZED, AND THE POSSIBILITY OF A CRASH IS INCREASED EXPONENTIALLY. PLEASE ADVISE GM THERE NEEDS TO BE A FIX FOR THIS AND ENSURE THEY COMPLY! THANK YOU FOR YOUR TIME. I BELIEVE MY PHOTOS OF THE BLOWER MOTOR FAN RESISTOR BEING BURNT HELPED GET GM ISSUE A RECALL, AND I HOPE THIS WILL URGE THEM TO FIX AS WELL

I HAVE BEEN HAVING SECURITY ISSUES WITH THIS VEHICLE FOR THE LAST 2 YEARS. KEEPS ME STRANDED AT TIMES UNTIL THE SYSTEM RESETS ITSELF. MY HOOD IS RATTLING AND AM AFRAID ONE DAY IT WILL COME OFF. DON'T WANT TO TRADE IT IN BUT MAY NOT HAVE A CHOICE. IF COMPANIES ARE AWARE OF THESE PROBLEMS THEY NEED TO FIX THEM BEFORE SOMEONE GETS KILLED OR SERIOUSLY INJURED. IT IS A TOTAL SHAME THAT CONSUMERS HAVE TO DEAL WITH ALL THESE PROBLEMS AND BY THE WAY PAYING HIGH CAR OR TRUCK NOTES A MONTH AND HAVING TO DEAL WITH EXTRA PROBLEMS WE DON'T NEED OR WANT. FIX EVERYTHING RIGHT THE FIRST TIME AND THERE WON'T BE SO MANY COMPLAINTS COMING YOUR WAY. I HAVE TAKEN MY VEHICLE IN MORE THAN ONCE FOR RECALLS ON THIS VEHICLE. PLEASE DO SOMETHING ABOUT THESE PROBLEMS BEFORE SOMEONE GETS SUED. THANK YOU FOR YOUR TIME.

OUR 2007 H3 HAD CRACKED RADIATOR WITH HOSE LEAKING COOLANT CAUSING THE OVERHEATING. WE HAVE NEVER DRIVEN THE VEHICLE OFF-ROADING AND NO WARNING LIGHT WAS DISPLAYED FOR THIS ISSUE. INSTEAD, WE BROUGHT IT IN FOR A DIFFERENT ISSUE WITH THE FUEL LINE AND DISCOVERED THE CRACKED RADIATOR, WHICH COULD HAVE CAUSED A BIGGER PROBLEM IF IT HAD GONE UNDISCOVERED FOR LONGER PERIOD OF TIME.
