TL* THE CONTACT OWNS A 1998 ISUZU TROOPER. THE CONTACT STATED THAT THE VEHICLE INDEPENDENTLY ACCELERATED WHEN SHIFTING FROM PARK INTO ANY OTHER GEAR WITHOUT WARNING. ALSO, THE RPMS INCREASED AND THE CONTACT HAD TO APPLY FORCE TO THE BRAKE PEDAL TO STOP THE VEHICLE. AN UNKNOWN DEALER THAT WAS NO LONGER IN BUSINESS WAS CONTACTED. THE DEALER RETAINED THE VEHICLE FOR MORE THAN TWO WEEKS, BUT THEY WERE UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE WAS ALSO TAKEN TO AN INDEPENDENT MECHANIC. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 30,000.

WHEN IDLING THE VEHICLE IS IDLING VERY HIGH. ALSO THE CHECK ENGINE LIGHT IS COMING ON, AND WHILE DRIVING THE VEHICLE AS YOU START TO LET OFF THE ACCELERATOR, THE VEHICLE JERKS YOU, ALMOST TO THE POINT OF GETTING WHIPLASH. WE HAVE HAD IN THE SHOP AT LEAST 3-4 TIMES AND LOTS OF TIMES FOR A WEEK AT A TIME. WE WERE TOLD THAT THE CHECK ENGINE LIGHT WAS DUE TO THE GAS CAP, THEY REPLACED THAT, 2 DAYS LATER IT WAS BACK ON. THEY ALSO SAID IT WAS THE FUEL SENSOR, REPLACED THAT AND ITS STILL ACTING AS THOUGH ITS NOT GETTING ENOUGH GAS. AS FAR AS THE JERKING OF THE VEHICLE THEY WONT TELL US WHAT COULD BE CAUSING THAT. ALSO THE MECHANIC STATED THAT THERE WAS NOTHING THAT THEY COULD DO TO RESOLVE THESE PROBLEMS. THIS VEHICLE IS AN ACCIDENT WAITING TO TAKE OTHERS LIVES. *TR

JUST BOUGHT A 98' TROOPER WITH THE 3.5L. DROVE IT FOR 1 WEEK AND GOT THE OIL CHANGED. DROVE IT FOR ANOTHER WEEK AND THE CHECK ENGINE LIGHT CAME ON. TOOK IT TO AN AUTO PARTS STORE AND HAD IT CHECKED WITH A HANDHELD SCANNER. IT SAID LOW FLOW THROUGH EGR VALVE. TECH SAID TAKE IT OFF AND CLEAN IT, SHOULD BE OK. NEXT DAY ON THE WAY HOME MOTOR STARTS KNOCKING. BABIED IT HOME, NOW KNOCKING VERY BAD. CHECKED OIL, IT WAS DRY. NO WARNING! NOTHING! I ONLY WENT 500 MILES AFTER THE OIL CHANGE. THE TRUCK IS GOING IN FOR A REBUILD. THIS IS GOING TO COST $4000. I HAVE NOT EVEN MADE A PAYMENT ON IT YET! THIS IS ABSURD. NOW, AFTER THE FACT, I HAVE READ ALL THE FORUMS ON THIS SITUATION. TOO LATE FOR ME. AFTER ALL THIS TIME HOW IS ISUZU NOT BEING MADE TO BE HELD RESPONSIBLE FOR THIS? WHAT ABOUT CLASS ACTION? SEEMS LIKE A GREAT TRUCK OTHERWISE.

I HAVE A 1998 ISUZU TROOPER WITH A 3.5L MOTOR AND IT EATS MOTORS OIL LIKE NO OTHER. IT DOES IT EVERYTIME I HAVE CHANGED THE OIL SINCE AFTER ABOUT 50K MILES. THE MOTOR CONSUMES ROUGHLY 1QT OF OIL EVERY 1000 MILES, EVEN AFTER A RECENT OIL CHANGE. I HAVE LOOKED ON COUNTLESS WEB SITES AND FORUMS ALL OVER AND THIS IS A VERY COMMON PROBLEM. PEOPLE JUST DO NOT KNOW ABOUT THIS WEB SITE AND WHAT YOU DO. THIS PROBLEM WILL PERSIST AND EVENTUALLY END UP IN ENGINE FAILURE AND CAN BE A VERY COSTLY PROBLEM. THOUSANDS OF DOLLARS LATER AND A NEW MOTOR, ONE WILL STILL HAVE THIS PROBLEM FOR THERE IS NO WAY TO FIX IT. THE DRAIN BACK HOLES IN THE OILS RINGS IS WHAT I HAVE BEEN TOLD THE PROBLEM IS. PLEASE CONTACT ISUZU ABOUT THIS PROBLEM AND HAVE THEN DO A RECALL PLEASE! IT WOULD SAVE A LOT OF MONEY FOR EVERYONE WHO DRIVES A 3.5L ISUZU/ACURA MOTOR. *JB
