20070824ENGINE AND ENGINE COOLING:ENGINE
ON 21 AUGUST 2007 MY 2003 BUCK RENDEZVOUS CXL AWD WITH APP 60,050 MILES SUFFERED A COMPLETE ENGINE FAILURE DUE TO WHAT MY MECHANIC BELIEVES IS A FAILURE OF THE WRIST PIN IN THE LEFT MOST FRONT CYLINDER. THE CAR WAS WELL MAINTAINED FOR RECEIVING REGULARLY SPACED OIL CHANGES. PER MY MECHANIC'S OPINION FAILURE OF THIS PART IS NOT AN INDICATION OF EXCESSIVE WEAR OR TEAR OR LACK OF VEHICLE CARE. THE CONSEQUENCE OF THE FAILURE OF THIS WRIST PIN IS THE DESTRUCTION OF THE ENTIRE ENGINE. PER MY MECHANIC'S OPINION THERE IS NO WAY TO SALVAGE AN ENGINE THAT HAS SUFFERED THIS TYPE OF INCIDENT. THE CORRECTION OF THIS INCIDENT WILL INVOLVE THE REPLACEMENT OF THE ENTIRE ENGINE. *TR

LAST YEAR AFTER REFUELING THE 03 BUICK RENDEZVOUS IT WOULD NOT CRANK. SINCE THEN, OCCASIONALLY IT HAS DONE THE SAME. RECENTLY, IT WON'T START AT ALL WITHOUT TAKING 30 + MINUTES OF RETRYING AND RETRYING. THE DEALER REPLACED THE FUEL LINES ,AND SAID THAT IT WAS PROBABLY THE PROBLEM. AFTER SPENDING $400 FOR THAT THE CAR IS STILL NOT CRANKING.*AK

WAS TOLD BY DEALER THAT THE NORMAL OIL CONSUMPTION OF 1 QUART IN 2000 MILES WAS NORMAL ACCORDING TO THE MANUFACTURER FOR A BUICK LESABRE '03 V6 ENGINE. I THOUGHT IT WAS RIDICULOUS FOR A BRAND NEW CAR! I'D APPRECIATE ANY INFO ON THIS. *NM
