So the part that is a malfunction is the rear doors weren’t made with any child lock and of course one of my kids opened the door while i was driving on the highway.I have a 3 and 5 year old and it scared me so bad I had to hurry and pull the hummer over and park and just held my son. I couldn’t even drive after that because of how bad it traumatized me. My mom had to come get and take me and my kids home and drive my hummer back home. Even though we didn’t crash or one of my kids didn’t fall out.it’s still a very serious safety hazard. I reached out to gm to see what my options were and there response was how gm made child locks in 2007 and up and that’s not the truth because mine is a 2007 and it clearly doesn’t have child locks. Then they later proceeded to tell me I should just sell my vehicle. I was so upset because if one of my kids would have fallen out and something happened I would do everything in my power to make sure they were held accountable and file a lawsuit against them. Yes The vehicle is available to inspect. My kids safety was at risk and then me braking and pulling off the highway in panic mode could have caused an accident.it’s been reported to gm and also local dealers. There was no warning just when it happened scared me so bad because my kids are in my back seat. The photos I uploaded are of the transcribed voicemails and I’m willing to also submit the voicemails from gm as well.
Sunroof leaks & drain's don't work , my heart wiring plug has melted , do to water my car worning lights all were flashing then dash lights & speedometer all crashed and soon as I parked would not start. I took a dehumidifier put it in the shop and dried it out then everything worked again.

ON 3/13/2020 MY WIFE WAS DRIVING OUR 2007 HUMMER H3 WHEN THE ENGINE COMPARTMENT AND DASH AREA CAUGHT ON FIRE. THE BLOWER MOTOR CONNECTOR MODULE HAD BEEN REPLACED RECENTLY AS PART OF A SAFETY RECALL. THE VEHICLE WAS IN MOTION AND SHE HAD JUST MADE A LEFT TURN. ALTHOUGH THE PART HAD BEEN REPLACED, I STILL BELIEVE THAT THIS RECALL ISSUE WAS THE CAUSE OF SAID FIRE. THE FIRE DEPARTMENT CALLED IT AN ELECTRICAL ISSUE. THERE WAS NO WARNING AT ALL. THIS WAS TRAUMATIC FOR MY WIFE SHE HAD TO JUMP OUT OF THE VEHICLE AND HAD A MISCARRIAGE.
WITH NO WARNING LIGHTS OR SIGNS, H3 WOULDN'T ACCELERATE WHILE PRESSING THE GAS.
OIL LIGHT COMES ON WHEN IDLE. TRUCK LOSES PRESSURE. NO DEALERSHIP SOLUTION.
PASSLOCK ISSUES NOT ALLOWING THE VEHICLE TO START. WAIT 10MIN WITH MULTIPLE ATTEMPTS.

I STOPPED AT GAS STATION FOR FUEL. VEHICLE WOULD NOT START FOR APPROXIMATELY 10 MINUTES AFTER FUELING UP. THEN IT STARTED. APPARENTLY THIS IS A WIDE SPREAD PROBLEM WITH THE HUMMER, AS I HAVE READ A NUMBER OF INCIDENTS REPORTED ON LINE WITH SAME ISSUE.

YESTERDAY, JANUARY 9, 2018, THE LOUVRE ON THE FRONT OF MY VEHICLE BLEW OFF WHILE I WAS DRIVING. IT WAS SUBSEQUENTLY RUN OVER BY THE VEHICLE BEHIND ME AND BROKEN. LUCKY NO ONE WAS HURT. IN RESEARCHING THE REPLACEMENT PART, I CAME TO LEARN THAT THERE WAS A RECALL ISSUED TO REMEDY THE PROBLEM. I CONTACTED CADILLAC OF DUBLIN TO REPLACE/REPAIR THE LOUVRE. THEY THEN INFORMED ME THAT THE RECALL HAD BEEN DONE AT JEFF WYLER IN KY. THIS IS CATEGORICALLY UNTRUE. CLEARLY, THE RECALL WAS NOT DONE. THERE IS ABSOLUTELY NO GLUE RESIDUE ANYWHERE ON MY VEHICLE OR THE LOUVRE. MOREOVER, HAD JEFF WYLER ACTUALLY PERFORMED THE RECALL, IT FAILED. MISERABLY. I SHOULD NOT BE RESPONSIBLE TO PAY FOR THE PART NOR THE REPLACEMENT THEREOF. THE INFORMATION IN THE RECALL SYSTEM NEEDS TO BE CORRECTED/UPDATED/REVISED TO ACCURATELY REFLECT THAT THE RECALL WAS NOT DONE, SO THAT I CAN ACTUALLY HAVE THE SITUATION CORRECTED/REQUIRED WORK PERFORMED.
