NHTSA Complaint #10311660 — 2003 BUICK RENDEZVOUS

1ST TIME: DRIVING INTO PORTLAND, OR. WHEN ENGINE STARTED TO MAKE A AWFUL NOISE BY THE TIME I FOUND A DEALER THE SOUND WAS AWFUL. THE DEALER SAID THAT I HAD 1 PUSH ROD JAMMED AND LOCKED UP. IT WAS REPLACED. 2ND.TIME 1 YEAR TO THE MONTH IT HAPPENED AGAIN. TOOK TO DEALER AND #4 LOCKED UP AND BENT. THE DEALER SAID THIS IS BECOMING A COMMON ITEM WITH THIS CAR. IT SEEMS THAT BECAUSE OF THE ALUMINUM BLOCK EXPANDS AND RETRACKS WHEN IT IS HOT THAT THE BOLT USED TO PUSH THE ROD COMES LOOSE AND CAUSES THE ROD THE FINELLY BEND. I CHECK WITH ANOTHER REPAIR SHOP AND THEY HAD, HAD 2 IN THE LAST YEAR. I WAS TOLD THIS WILL CONTINUE TO HAPPEN UNTIL I REPLACE ALL RODS. AT WHICH TIME THEY WILL PUT IN NEW BOLTS WITH LOCK TIGHT SO THEY WILL NOT COME LOOSE.SO FAR I HAVE BEEN LUCKY THAT ONLY ONE AT A TIME HAS GOOD. IF TWO HAD GONE OUT THEY SAID I PROBABLY WOULD HAVE LOST CONTROL OF THE CAR. AS IT WOULD LOCK UP. *TR
