NHTSA Complaint #10578151 — 2007 HUMMER H3

I OWN A 2007 HUMMER H3 WITH 66000 MILES ON IT. IT HAS BEEN DIAGNOSED AS HAVING A BAD HEAD DUE TO THE USE OF SOFT METALS FOR THE CYLINDER SLEEVE. DUE TO THIS, THERE IS SUDDEN REDUCED POWER. THE COST OF THIS FIX IS ABOUT $4500.00. MY TRUCK BEGAN WITH A CHECK ENGINE LIGHT ON (AUTOZONE) SAID IT WAS A MISFIRE ON CYLINDER #5. I WENT TO THE LOCAL DEALER AND ASKED THEM TO LOOK AT THE TRUCK. THEY DIAGNOSED IT AS A #5 CYLINDER HAVING THE COMPRESSION LEAK OF 90%. IN LOOKING ON THE INTERNET (AT HUMMER FORUMS), I OBSERVED THAT QUITE A FEW HUMMER H3 OWNERS WERE WRITING IN ABOUT THEIR EXPERIENCE WITH MISFIRES AND BAD HEADS, AT ABOUT THE SAME MILEAGE. I THINK THIS NEEDS TO BE LOOKED INTO AND THAT GM SHOULD BE ORDERED TO DO A RECALL. THIS IS THE SAME PROBLEM THEY HAD WITH THE 3.5L ENGINES THEY USED IN THEIR PRE-2007 HUMMER H3 AND COLORADO. I AM GOING TO WRITE MY CONGRESS REP AND ASK THAT WITH THE PROBLEMS THAT GM IS HAVING RIGHT NOW, THAT THIS ALSO BE MOVED FORWARD AND THAT THEY ORDER AN INVESTIGATION. ANY OTHER HUMMER H3 OWNERS WITH THE SAME PROBLEMS SHOULD DO THE SAME THING. *TR
