ELECTRICAL SYSTEM
TL* THE CONTACT OWNS A 2000 ISUZU TROOPER. WHILE DRIVING AT 35 MPH, THE VEHICLE STALLED AND THE CHECK ENGINE WARNING LIGHTS ILLUMINATED. THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS DIAGNOSED BY THE OWNER AS A CERTIFIED MECHANIC. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 152,000.

ELECTRICAL SYSTEM
LOW BEAM HEADLIGHT SWITCH STOPPED WORKING. ONLY HIGH BEAMS WORKED. HAD TO HAVE THE HEADLIGHT SWITCH REPLACED AT A COST OF $500. I SEE THAT THE SAME PROBLEM IS CURRENTLY BEING ADDRESSED AND RECALLED ON LATER MODEL ISUZU ASCENDERS AND GM VEHICLES. I BELIEVE ISUZU USED MANY GM PARTS IN THIS TROOPER AND IT SHOULD BE INCLUDED IN THE CURRENT RECALL SO THAT I CAN GET REIMBURSED FOR THE REPAIRS.

ELECTRICAL SYSTEM
I WAS DRIVING ABOUT 35 MPH ON A RURAL ROAD AND I NOTICED THAT UPON GIVING SOME GAS THE VEHICLE DID NOT RESPOND AT ALL. THEN I NOTICED THAT ALL MY INSTRUMENT PANEL LIGHTS WERE OUT....EVERYTHING GONE. I APPLIED THE BRAKES AND WITH DIFFICULTY IN STEERING (THERE WAS NO POWER), I PULLED TO STOP AT THE SIDE OF THE ROAD. I THEN PUT THE VEHICLE INTO PARK AND TURNED THE IGNITION KEY OFF, THEN RESTARTED THE VEHICLE AND DROVE AWAY. THIS IS THE ONLY TIME THIS HAPPENED (LAST WEEK).....A COMPLETE LOSS OF POWER. I KNOW ISUZU SHARES PARTS WITH GM (E.G. MY TRANSMISSION IS GM). I HOPE THIS IS NOT AN EXAMPLE OF THAT GM IGNITION SWITCH PROBLEM.....BUT CERTAINLY HAS THE EXACT SAME SYMPTOMS OF IT. BUT IT IS VERY SCARY LOOSING COMPLETE POWER LIKE THAT.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL
POWER STEERING HOSE STARTED HAVE MASSIVE LEAK ALL OF A SUDDEN, AND IT WAS REPLACED THE FOLLOWING MORNING. THE POWER STEERING FLUID HAD SPRAYED ALL OVER EVERYTHING UNDER THE HOOD, WHICH INCLUDED SOAKING THE ALTERNATOR, WHICH IN TURN MADE THE ALTERNATOR START TO SURGE AT TIME, CAUSING THE TRANSMISSION TO GO IN TO BACK UP MODE, AND WOULD NOT DOWNSHIFT ON ITS OWN AFTER COMING TO STOP. ALSO EVERY WARNING LIGHT ON THE DASH BOARD WAS LIGHT UP, CHECK ENGINE, BATTERY, O2, AUTO CRUISE, LOW FUEL, AND CHECK TRANS. WHICH WAS ODD CAUSE I HAD FULL TANK OF GAS, THE BATTERY WAS SHOWING TO BE WITH IN RANGE ON THE VOLTAGE GAUGE, THE CRUISE CONTROL WAS OFF......AND THE TRUCK WAS NOT DOING ANYTHING STRANGE, DROVE FINE.

AN INTEGRATED CIRCUIT WITHIN THE VOLTAGE REGULATOR CAN CONTAIN MANUFACTURING ERRORS. THIS CAN CAUSE EXCESSIVE ELECTRICAL CHARGING OF THE VEHICLE'S ALTERNATOR, RESULTING IN ENGINE CONTROL MALFUNCTION OR EVENTUAL ENGINE STALL.

ELECTRICAL SYSTEM
ISUZU TROOPER 1999 PROBLEM AFTER PROBLEM, ENGINE BURNING OIL. *BF AFTER THE ENGINE WAS REPLACED, THE ENGINE LIGHT ILLUMINATED AT LEAST 30 TIMES. THE DEALER GAVE THE CONSUMER ALL TYPES OF EXCUSES UNTIL FINALLY THEY SAID THEY DIDN'T KNOW WHAT WAS CAUSING THE LIGHT TO ILLUMINATE. THERE WERE OTHER PROBLEMS SUCH AS A HARD SHIFT WITH THE TRANSMISSION, WATER LEAKING THROUGH THE SUN ROOF, DIFFICULTY STARTING THE VEHICLE, UNEVEN TIRE WEAR, IN JUST 65,000 THE CONSUMER HAS GONE THROUGH 3 COMPLETE SETS OF TIRES. THE CONSUMER WAS TOLD THERE WAS A PROBLEM WITH THE FRAME OF THE VEHICLE AND IT COULD NOT BE ALIGNED. THE TIE RODS WERE REPLACED BECAUSE THEY WERE DEFECTIVE. IN THE PAST THE VEHICLE LUNGED FORWARD WHILE THE CONSUMER HAD HER FOOT FIRMLY PRESSED ON THE BRAKE. THE VEHICLE INTERMITTENTLY IDLED HIGH WHILE STOPPED. THE VEHICLE HAS ROLLED BACKWARDS WHILE IT WAS IN PARK. ANOTHER MECHANIC INFORMED THE CONSUMER THE PREVIOUS DEALER INSTALLED SEVERAL ELECTRICAL COMPONETS INCORRECTLY AND THERE WERE ALSO SOME DEFECTIVE PARTS THAT NEEDED TO BE REPLACED WHICH CAUSED THE ENGINE LIGHT TO COME ON. THE CONSUMER WAS GETTING POOR GAS MILEAGE.

ELECTRICAL SYSTEM
IN OCTOBER 2004, WHILE DRIVING 65 MPH ON THE FREEWAY, CAR AUTOMATICALLY REDUCED POWER TO 5 MPH. DECELERATION OF AUTOMOBLIE WAS PRETTY RAPID. THE VECHILE WAS BROUGHT TO THE ISUZU DEALERSHIP. A NUMBER OF TESTS WERE RUN, BUT NOTHING WAS FOUND. SERVICE DEPARTMENT COULD NOT FIND ANY THING WRONG WITH THE VECHILE. ON JANUARY 25, THIS HAPPENED AGAIN WHILE DRIVING ON THE FREEWAY AT 65 MPH. THE VEHICLE WAS TOWED TO A ISUZU SERVICE DEPARTMENT. THEY REPLACED THE ACCELERATION SENSOR AND SAID THE VECHILE WAS FIXED AND PICKED UP ON JANUARY 27. ON JANUARY 28, THE VECHILE AGAIN LOST POWER WHILE DRIVING ON THE FREEWAY AT 65 MPH. THE VECHILE WAS TOWED AND BROUGHT INTO AN ISUZU DEALERSHIP (SAME DEALERSHIP AS IN OCTOBER). THEY COULDN'T FIND ANY CODES PRESENT AND SAID THE VECHILE WAS FINE- COULDN'T FIND A PROBLEM. ON JANUARY 31, THE SAME OCCURED. THE VECHILE LOST POWER WHILE DRIVING ON THE FREEWAY. AGAIN IT WAS TOWED TO THE ISUZU SERVICE (SAME SERVICE DEPARTMENT AS JANUARY 25-27). THEY CAN NOT FIND OUT WHAT THE PROBLEM IS. THEY CALLED ISUZU MAIN HELP LINE AND STILL HAVE NO ANSWERS. THE ISUZU CORP. SUGGESTED REPLACING THE THROTTLE BODY AND IF THAT DOESN'T FIX THE PROBLEM, THEN THE ELECTRICAL HARNESS. STILL NO GUARANTEE THAT THE MENTIONED SERVICES WILL FIX THE PROBLEM. LUCKILY, NO ACCIDENTS YET. VECHILE NOT SAFE TO DRIVE AND ISUZU WILL NOT COVER ANY REPAIRS EVEN THOUGH LOSS OF POWER IS A SAFETY ISSUE.

I BOUGHT A 1999 ISUZU TROOPER LIMITED EDITION 1 YEAR AGO THIS MONTH. SINCE BUYING IT I HAVE HAD THE STARTER REPLACED, THE ALTERNATOR REPLACED TWICE, THE SMALL BLOCK WAS BAD BECAUSE OF A FAILURE WITH THE DIPSTICK TO READ THE CORRECT AMOUNT OF OIL. MY SON WAS INVOLVED IN A MVA DUE TO THE FACT THAT THE VEHICLE WOULD NOT STOP AS THE ENGINE DECIDED TO RACE WHILE HE WAS COMING TO A SLOW STOP. THANK GOD NO ONE WAS INJURED IN THE ACCIDENT. THE CAR REVS UP AT AN IDLE AT A STOP OR SLOWING DOWN POSITION, AND NOW THE VEHICLE IS IN THE GARAGE BECAUSE THE TRANSMISSION IS BAD AND THE ALTERNATOR WENT AGAIN. THE FRONT WINDSHIELD IS NOT PROPERLY SEALED AND THE WINDOW FOGS UP IF YOU DON'T RUN THE DEFROSTER. THE DRAFT THAT COMES FROM THE FLOOR ON THE DRIVERS SIDE IS UNACCEPTABLE. I BOUGHT THIS CAR WITH LESS THAN 30,000 MILES ON IT AND IT NOW HAS LESS THAN 50,000. I REALLY DON'T UNDERSTAND WHY A VEHICLE WITH THIS LOW MILEAGE HAS SO MANY PROBLEMS AND IT IS IN THE SHOP MORE THAN IT IS OUT. I EXPECTED TO HAVE SOME PROBLEMS WITH A USED VEHICLE BUT NOT THIS MANY AND NOT THIS COSTLY! I HAVE BEEN READING ABOUT MANY SIMILAR PROBLEMS WITH THIS YEAR OF TROOPER AND I'M WONDERING WHAT IT'S GOING TO TAKE TO HAVE THE COMPANY STAND UP AND TAKE RESPONSIBILITY.

WHILE DRIVING ALL ELECTRICAL LIGHT APPEARED ON THE DASHBOARD AND REMAINED ON. VEHICLE STALLED. CONSUMER DROVE THE VEHICLE TO THE DEALER FOR INSPECTION, AND MECHANIC STATED THAT THE VEHICLE HAD TO BE PLACED ON A DIAGNOSTIC MACHINE FOR RESULTS. CONSUMER INFORMED THE MECHANIC THAT THIS PROBLEM OCCURRED MORE THAN ONCE. MECHANIC ADVISED CONSUMER THAT THE PROBLEM COULD NOT BE DETERMINED AT THIS TIME.

ELECTRICAL SYSTEM:STARTER ASSEMBLY
I BROUGHT MY VEHICLE INTO THE DEALERSHIP FOR A TUNE UP AND 120000 MAINTAINANCE. EVERYTHING ON THE VEHICLE WAS WORKING PERFECTLY. I HAD MADE THE APPOINTMENT 2 WEEKS IN ADVANCE AND KEPT TO THE SCHEDULE. THE DEALERSHIP CALLED ME TO SAY THAT IT WAS DONE FOUR DAYS LATER AND THAT THE STARTER WAS NOT WORKING. THEY ADMITTED THAT IT HAD BEEN WORKING PERFECTLY AND HAD JUST "STOPPED" WORKING WHILE THEY WERE MOVING IT AROUND AND RUNNING IT THROUGH THE WASH. I EXPLAINED THAT EVERYTHING HAD BEEN WORKING PERFECTLY WHEN I BROUGHT IT IN AND THEY AGREED TO REPLACE THE STARTER WITH A REBUILT FOR NO CHARGE. THEY DID SO AND I PICKED UP THE CAR. IMMEDIATELY UPON LEAVING THE DEALERSHIP I CALLED THEM AND TOLD THEM THAT THE MOTOR WAS NOT RUNNING RIGHT. THEY ASKED THAT I CONTINUE TO DRIVE IT FOR A COUPLE OF DAYS BECAUSE THE "COMPUTER WOULD FIX THE PROBLEM". I CONTINUED TO DO SO AND THE NEXT DAY IT WAS HOT SO I TRIED THE AIR CONDIIONER AND IT MADE GRINDING NOISES. I CALLED THEM AGAIN AND BROUGHT IT IN AGAIN AND THEY SAID THAT IT MUST HAVE JUST GONE OUT, AT THE SAME TIME AS THE STARTER WHILE IT WAS IN THEIR POSSESSION. THEY SAID THAT IT WOULD COST ME $1100.00 TO REPLACE THE COMPRESSOR, WHICH I STATE ONCE AGAIN WAS WORKING PERFECTLY WHEN I BROUGHT IT IN. THEY DID SOMETHING TO RUIN MY AIR CONDITIONER AND NOW EXPECT ME TO PAY FOR IT!!! PLEASE HELP SHARRON .

MY 1990 ISUZU TROOPER IS EXHIBITING DANGEROUS REVVING AND DROPPING OF THE IDLE. THE TRUCK ACCELERATES WITHOUT WARNING AND IS IMPOSSIBLE NOW TO DRIVE SAFELY. IT IS MY UNDERSTANDING THAT THE ECU IN THESE TRUCKS IS FAULTY DUE TO MANUFACTURING DEFECTS. I FURTHER UNDERSTAND THAT THOUSANDS OF OTHERS HAVE THESE PROBLEMS. PLEASE INITIATE A RECALL OF THESE VEHICLES AND FORCE ISUZU TO REPAIR THESE DANGEROUS DEFECTS AT THEIR EXPENSE, NOT THE CONSUMERS'. PLEASE TAKE ACTION ON THIS EXTREMELY DANGEROUS SITUATION. I WOULD APPRECIATE YOUR INSTRUCTING ISUZU TO CONTACT ME WITH INFORMATION ON WHERE I CAN HAVE MY TRUCK TOWED TO BE REPAIRED. IT IS NOT SAFE TO DRIVE IT. SEVERAL GARAGES SAID THEY CANNOT DIAGNOSE AND FIX THE PROBLEM, AND THAT ISUZU MUST RESOLVE THE PROBLEM. MANY THANKS FOR YOUR CONSIDERATION. *NLM

VEHICLE HAS HAD LARGE NUMBER OF PROBLEMS WHICH LOCAL DEALER AND FACTORY REP. CANNOT IDENTIFY/FIX. AT HIGHWAY SPEEDS (AND SLOWER) CAR WILL SUDDENLY AND VIOLENTLY "SHUDDER" AS IF DYING, ONLY TO THEN RESUME SPEED AS IF NOTHING HAD HAPPENED. ALSO DIES OFTEN AT LIGHTS AND SLOW SPEEDS. DEALER/ISUZU NO HELP. LOOKS LIKE A VERY COMMON PROBLEM WITH THE '99 TROOPER, BASED ON OTHER COMPLAINTS...IF YOU'VE HAD SOME OF THESE 'SYMPTONS,' PLEASE EMAIL ME...PERHAPS WE CAN ASSIST EACH OTHER!

NO WARNING LIGHTS.OIL WAS GONE FROM CAR AND NO IDICATOR LIGHTS WARNED OF LOW OIL. NOW ENGINE BURNT UP AND THE ISUZU DEALER WANTS TO CHARGE ME $9,200 TO FIX. OIL HAD BEEN CHANGED 2400 MILES BEFORE INCIDENT. NO OIL LEAKS FOUND.
