Open the full vehicle complaint log (all categories)03 ISUZU RODEO 3.2L BURNING EXCESSIVE AMOUNT OF OIL. TAKES A QUART EVERY 250 MILES. DONE EVERYTHING RECOMMENDED AT THE RECOMMENDED INTERVALS, OIL CHANGES, EGR VALVE, PCV VALVE, ECT. I AM VERY GOOD ABOUT CHANGING RECOMMENDED PARTS WHEN NEEDED. THIS ENGINE SHOULD NOT BE TAKING OIL. I DO NOT TOW OR REV OVER 5,000 RPM, EVER! OTHER ISUZU OWNERS HAVE ALSO EXPRESSED CONCERNS ABOUT THIS TO ME, THIS SEEMS TO BE A FAIRLY COMMON PROBLEM WITH THE ISUZU ENGINE. I NOW NEED TO REPLACE THE ENGINE AT A COST OF 3,000 PLUS INSTALLATION LABOR CHARGES. THIS IS THE THIRD RODEO I HAVE HAD, GOOD LUCK WITH THE OTHER TWO, BUT NOT THIS ONE. IF THIS CANNOT BE RESOLVED, I WILL PURCHASE ANOTHER MODEL IN THE FUTURE. *TR
2003 RODEO ENGINE FAILUE AT 48K. ISUZU REFUSES TO REPAIR UNDER WARRANTY AND BLAMING ME FOR DAMAGE BECAUSE I CANNOT PRODUCE ALL OF MY OIL CHANGE RECIEPTS. MY 2000 RODEO ENGINE FAILED AT 35K AND ISUZU REPLACED UNDER WARRANTY. I AM AMAZED AT HOW MANY COMPLAINTS AND "OIL USAGE" POST I AM FINDING ON THE WEB FROM OTHER ISUZU OWNERS.
WHILE DRIVING AT ANY SPEED A KNOCKING NOISE WAS PRODUCED FROM THE ENGINE. *AK
