ENGINE
The contact owns a 2001 Isuzu Trooper. The contact stated while entering and starting the vehicle, he noticed an extreme heat in the interior of the vehicle coming from the engine. The contact proceeded to shift the gear into drive however, while his foot was still on the brake pedal the vehicle independently accelerated. The contact had to pulled up the parking brake to stop the vehicle. The contact stated that the failure recurred several times afterwards. The contact took the vehicle to an independent mechanic who diagnosed the failure as a bypass for the fuel line and brake line failure that needed to be replaced however, the mechanic was unable to determine the cause for the heat entering the vehicle from the engine. The mechanic was able repair the vehicle however, the contact was concerned that the heat coming from the engine would eventually destroy the engine and the vehicle would need to be replaced. The manufacturer was not made aware of the failure. The approximate failure mileage was 101,000.

ENGINE AND ENGINE COOLING
ACCELERATED FROM STOP AND THROTTLE STUCK. WAS ABLE TO SHUT DOWN ENGINE AND GET TO SIDE OF ROAD. INSPECTED CABLE AND FOUND THAT RUBBER BOOT ON ENGINE SIDE OF CABLE HOUSING HAD BECOME GUMMY/STICKY/SOFT AND HAD FOLDED IN ON ITSELF, STICKING TO THE INNER CABLE ITSELF. REMOVED BOOT TO GET HOME. LOOKED ONLINE FOR REPLACEMENT, AND FOUND THAT THERE HAD BEEN A RECALL FOR EXACT SAME PROBLEM ON EXACT SAME MODEL AND YEAR, BUT AFTER CALLING ISUZU, WAS TOLD THAT MY VIN WAS NOT PART OF THE RECALL, THOUGH IT'S THE SAME PART NUMBER. OBVIOUSLY THE RECALL WAS INCOMPLETE, AND THERE ARE STILL CARS OUT THERE WHICH, LIKE MINE, HAVE THE SAME FAULTY SPEED CONTROL COMPONENTS. HAD I NOT KNOWN TO TAKE THE CAR OUT OF GEAR AND SHUT DOWN THE ENGINE, THERE COULD HAVE EASILY BEEN A CRASH. MY WIFE DRIVES MY 2 YEAR OLD SON IN THIS CAR. I ASK YOU TO PLEASE LOOK INTO THIS ISSUE ON BEHALF OF PUBLIC SAFETY.

ENGINE AND ENGINE COOLING
MY SUV , ISUZU TROOPER OF 10YEARS, WAS PARKED IN A LIBRARY PARKING GARAGE AND AFTER IGNITION TURNED ON, I PUT IT IN REVERSE GEAR TO GET OUT OF THE PARKING LOT AND THE CAR RAPIDLY REVERSED AND BEFORE I COULD FIGURE OUT AND REACT, THE CAR SHOT LIKE A ROCKET TOWARDS THE FRONT , WHILE STILL IN REVERSE GEAR, AND I HAD NO CONTROL OF THE BRAKES OR STEERING WHEEL, IT RAMMED INTO A CONCRETE PILLAR AND GOT COMPLETELY TOTALED. AIRBAGS OPENED AND FRONT DOORS JAMMED AND I HAD SLIDE TO THE BACK TO ESCAPE. LUCKILY, CAR DID NOT CATCH ON FIRE OR EXPLODE. ( POLICE REPORT VERIFY THAT AFTER CRASH, CAR STILL FOUND TO BE IN REVERSE GEAR AND SUPRISED HOW CAR MOVED TOWARDS THE FRONT). A WEEK AGO, PRIOR TO THIS FREAKY CRASH, ( LUCKILY NO MINORS, SENIORS, HOMELESS WHO USUALLY WALK IN THE PARKING LOT WERE NOT PRESENT, OTHERWISE, THERE WOULD HAVE BEEN MULTIPLE DEATHS) MY CAR DEALERSHIP HAD DONE WORK ON MY CAR FOR NEARLY $1000.00. AND THEY REPLACED MODE SWITCH FOR MY AUTOMATIC TRANSMISSION ( THERMOSTAT CHANGED; PISTON COVER CHANGED) AND DON'T KNOW WHAT ROLE IT PLAYED IN MY CAR'S CRASH. I AM PRETTY SURE ITS A MALFUNCTION . IT NEEDS TO BE ASSESSED AND FIGURED WHAT ROLE THE ABOVE INSTALLATION PLAYED IN THE CRASH WHICH COULD HAVE HAD DISASTROUS CONSEQUENCES. WAS IT DUE TO DEFECTIVE PART? INSURANCE COMPANY BLAMES IT ON ME AND SAY MY PREMIUMS WILL BE HIGHER SINCE ITS AT FAULT ACCIDENT DESPITE HEARING MY EXPERIENCE AND WITH EVIDENCE OF POLICE REPORT WHICH STATES THAT MY GEAR WAS STILL IN REVERSE. ( AFTER CRASHING HEAD ON AGAINST A CONCRETE PILLAR) THANK YOU FOR KEEPING PUBLIC SAFETY FIRST!

ENGINE AND ENGINE COOLING
I CHECKED MY OIL LEVEL 3 WEEKS AGO AND IT WAS FINE. I CHANGE MY OIL EVERY 3000 MILES. I ADDED A QUART 3 DAYS AGO FOR A LONG TRIP I WAS TAKING. WHILE DRIVING DOWN TO BILLINGS, MT, MY CAR SUDDENLY STOPPED. IT HAD NOT OVERHEATED OR SHOWN A WARNING SIGN. MY CAR WAS BONE DRY OF OIL! THE ENGINE HAS SEIZED. I DID EVERYTHING RIGHT...THIS IS CLEARLY A DESIGN FLAW IN THE CAR.

ENGINE AND ENGINE COOLING
99 ISUZU TROOPER 3.5 ENGINE BURNS OIL EXCESSIVELY. I AM ORIGINAL OWNER AND REGULARLY SERVICED PER OWNERS MANUAL. AT 50K MILES, ENGINE OIL LIGHT TURNED ON 2,500 MILES AFTER OIL CHANGE AND WAS OVER 4 QTS LOW. ENGINE NOW AT 60K MI AND BURNING APPROX. 1 QT PER 600-700 MILES. SEEMS TO BE COMMON ENGINE DEFECT KNOWN BY MECHANICS AND OWNERS, BUT ISUZU UNWILLING TO ACKNOWLEDGE PROBLEM. THOUGH MONITORING CONSTANTLY, I AM JUST WAITING FOR SIGNIFICANT ENGINE FAILURE.

NHTSA complaint #10310412 — an unverified report by a vehicle owner.
ENGINE AND ENGINE COOLING
AFTER MAINTAINING OUR 2000 ISUZU TROOPER BY THE BOOK AND BEING FULLY AWARE OF THE OIL CONSUMPTION PROBLEM, IT BLEW THE ENGINE AT 103000. I KEPT VERY GOOD DOCUMENTATION OF ALL THE REPAIRS- AND THERE WERE A LOT OF THEM, ISUZU IS NOT BACKING THEIR POWERTRAIN WARRANTY (120,000 MILES)BECAUSE THEY FOUND A WAY TO GET AWAY WITH IT BY SAYING BECAUSE I DIDN'T HAVE ACTUAL RECEIPTS FOR EVERY OIL CHANGE EVEN THOUGH I DID MANY MYSELF AND DOCUMENTED DATES AND MILEAGE, THEY ARE NOT RESPONSIBLE. I'VE DONE SOME RESEARCH WHICH WAS EASY BECAUSE ITS SUCH A COMMON PROBLEM, BUT DIDN'T FIND MUCH ON ANY TROOPER OWNERS SATISFIED OR FAIRLY TREATED BY ISUZU. THE STICKER PRICE WAS $32,000 WHEN I PURCHASED IT IN 2000 I FULLY EXPECTED TO GET MORE THAN 103,000 OUT OF IT. IF ANYONE HAS ANY LUCK WITH THE SAME PROBLEM,PLEASE LET ME KNOW AND IN THE MEAN TIME IM GOING TO DO AS MUCH AS I CAN TO FIGHT THIS.

ENGINE AND ENGINE COOLING
I GET FREQUENT OIL CHANGES IN MY 99 ISUZU TROOPER AND HAD JUST GOTTEN ONE LAST MONTH. I HAD AT LEAST 2700 MILES BEFORE MY NEXT ONE. I WAS DRIVING DOWN THE FREEWAY AND I SAW SMOKE COMING FROM MY HOOD AND ALL MY DASH LIGHTS CAME ON LIKE A CHRISTMAS TREE. I PULLED OVER AND FOUND OUT THAT MY ENGINE WAS ON FIRE. I CALLED THE FIRE DEPT TO PUT IT OUT AND GOT IT TOWED TO MY HOUSE TO LATER FIND OUT THAT THE PISTON HAD GOT THROWN FROM THE ENGINE BECAUSE IT LOCKED UP DUE TO NO OIL GETTING TO THAT PISTON. SO NOW I HAVE TO GET A NEW ENGINE WHICH COST ABOUT THE SAME AS THE CAR.

ENGINE AND ENGINE COOLING:ENGINE:GASOLINE
I BOUGHT IT USED IN OCT 2007 WITH 60,000 MI ON IT. THE OIL GETS CHANGED EVERY 3,000 MI BUT I NEED TO ADD A QT OF OIL EVERY 700 MI. AS FAR AS GAS MILEAGE (IT'S THE PITS ) MAYBE 11 MPG AT BEST. I THOUGHT ISUZU WAS A GOOD BUY (GUESS NOT).
NHTSA complaint #10223846 — an unverified report by a vehicle owner.
ENGINE AND ENGINE COOLING:ENGINE
I TOOK MY '99 ISUZU TROOPER TO GET AN OIL CHANGE, AND 3 WEEKS LATER THE OIL LIGHT TURNED ON. I WENT TO THE ISUZU DEALERSHIP WHERE I BOUGHT THE CAR AND AFTER CHECKING THE OIL, THEY NOTICED THAT THERE ARE LESS THAN A LITER IN THE ENGINE. THEY FILLED IT AND ADDED A CONDITIONER TELLING ME THAT THAT SHOULD FIX THE PROBLEM. A FEW MONTHS LATER, DRIVING BACK FROM A TRIP, THE ENGINE BEGAN KNOCKING AND THE OIL LIGHT CAME ON AGAIN. MOMENTS LATER I LOST POWER (RPMS) AND PULLED THE CAR OVER. THE MECHANIC WHO LOOKED AT MY CAR TOLD ME (AND THIS WAS CONFIRMED BY A CONSUMER REPORT WEBSITE) THAT '99 TROOPERS OFTEN HAVE "UNEXPLAINED LOSS OF OIL PRESSURE RESULTING IN THE ENGINE SEIZING." THE CAR NOW NEEDS A NEW ENGINE (APPROX 4000-9000 DOLLARS) OR A NEW CAR. NOTHING HAS BEEN DONE TO CORRECT THE FAILURE OR DEFECT.
