NHTSA Complaint #10560454 — 2006 HUMMER H3

OWNER THE CAR SINCE 2006 WITH NO PROBLEMS--REGULARLY MAINTAINED, 125,000 MILES. AFTER A RECENT LONG TRIP MY WIFE TOOK IT TO THE SHOP WHERE SHE WAS TOLD THE ENGINE HAD "LOW COMPRESSION." THE SHOP WAS TRUSTED 100% AND BEEN USED FOR DECADES. SERVICE MANAGER SAID THEY WOULD SEE WHAT THEY COULD DO ABOUT THE LOW COMPRESSION AND THAT THEY WOULD HAVE TO CHECK EACH OF THE PISTONS. AFTER THE REVIEW, THE MANAGER SAID HE HAD BAD NEWS, THAT THE CAR NEEDED TO BE TRADED IN/SOLD IMMEDIATELY AND NOT TO DRIVE IT UNTIL IT WAS. I VERIFIED THE RESULTS WITH 2 OTHER MECHANICS THAT THE 5 CYLINDER H3S LOSE COMPRESSION OUT THE BLUE--COMMON AMONG 5 CYLINDER H3S. THE SHOP MANAGER BASICALLY TOLD ME THAT I NEED TO SELL/TRADE IN THE VEHICLE, BUT NOT TO DRIVE IT UNTIL I HAD DONE SO, APPARENTLY THIS ISSUE HAS HAPPENED TO 06 H3S RELIGIOUSLY WHERE THE COMPRESSION DIMINISHES AND LEADS TO THE ENGINE DYING. . IT'S A POSSIBLE TO BUY A USED ENGINE WITH THE POSSIBILITY THAT THE COMPRESSION COULD DIE AGAIN. NEEDLESS TO SAY, WE FEEL LIKE WE'VE BEEN PUNCHED IN THE GUT BY HUMMER. HOW CAN A CAR PERFECTLY MAINTAINED ALL OF A SUDDEN HAVE "LOW COMPRESSION" AND LEAD 3 PROFESSIONALS TO ADVISE US TO SELL IT L IT AS SOON AS POSSIBLE? THIS HAD TO HAVE BEEN KNOWN BY HUMMER AND THEY DID NOTHING ABOUT IT. MEANTIME, WE ARE PROBABLY OVER/UNDER ON THE VEHICLE AND WILL HAVE TO GET RID OF IT. *TR
