THE VEHICLE STALLS, INCOSISTENTLY, BUT, ON A FREQUENT BASIS, AT ANY GIVEN TIME, THEN WILL BE FINE FOR A LONG PERIOD OF TIME. IT EATS BATTERIES. I'VE HAD TO REPLACE THE BATTERY EVERY YEAR. A LOCAL AUTOMOTIVE ELECTRICAL SPECIALIST REPLACED THE B+ CABLE FROM THE BATTERY TO THE STARTER, AND THE PROBLEM WENT AWAY FOR A YEAR, BUT, HAS SINCE RETURNED. I RECENTLY UPGRADED TO A BATTERY WITH MORE CRANKING WATTS, AND HAVE EEN IMPROVEMENT. HOWEVER. THERE'S THE ISSUE OF THE HESITATION, JERKING, AND LOSS OF POWER, WHEN TAKING OFF AFTER 1ST START OF THE DAY, REPLACED PLUGS, AND BATTERY AND DID A TUNE - UP, BUT, IT MADE NO DIFFERENCE. VERY DANGEROUS AND HAVE ALMOST BEEN INVOLVED IN ACCIDENTS MULTIPLE TIMES, AS A RESULT, INCLUDING DYING WHILE TOWING A TRAILER, SMACK DAB IN THE MIDDLE OF A 4-WAY INTERSECTION OF A TRAFFIC - CHOKED COASTAL HIGHWAY IN THE MIDDLE OF A POPULAR BEACH RESORT, FEATURING OVER 200 OUTLET SHOPS AND MALLS, MID-DAY, ON THE 4TH OF JULY WEEKEND, AND A SATURDAY AT THAT,, AND HAVING TO CONTACT ROADSIDE ASSISTANCE 5 TIMES, TO GET IT GOING AGAIN, TO GET TO MY DESTINATION, LESS THAN 6 MILES AWAY, AND HAVING TO DRIVE ON THE ROAD'S SHOULDER THE WHOLE WAY, IN CASE OF ANOTHER BREAK-DOWN,

I HAVE 99 4 RUNNER AND AS I WAS DRIVING DOWN THE HIGHWAY MY VEHICLES ENGINE DIED, I HAD TO CUT ACROSS TRAFFIC WITHOUT POWER BRAKES OR STEERING. I SPOKE TO THE DEALER ABOUT MY PROBLEM AND THEY GAVE ME AN ESTIMATE OF AROUND $1000 DOLLARS, IF U LOOK ON THE INTERNET THERE SEEMS TO BE A LOT OF PEOPLE WITH THIS SAME ISSUE,I THINK THERE NEEDS TO BE A RECALL CONCERNING THIS ISSUE BECAUSE IT IS POSSIBLE TO CAUSE A COLLISION UNDER CERTAIN CIRCUMSTANCES.

DT: THE CONTACT STATED THE VEHICLE STALLS AND THE DEALER HAS BEEN UNABLE TO RESOLVE. THE CONTACT IS UNSURE IF THIS IS THE ENGINE AND THE TRANSMISSION. THE VEHICLE ALSO HAS A CONTINUOUS KNOCKING SOUND, AND A INTERMITTENT STALLING PROBLEM. ALSO THE VEHICLE HAS A VIBRATION WHEN IT IS ACCELERATING OVER 50 MILES PER HOUR.

(1) HIGH PITCHED ENGINE SQUEAK; ASSUMED WORN BELT. (2) MAIN PULLEY KEY LOCKING MAIN PULLEY TO CRANK SHAFT HAD SHEARED INTO TWO PIECES. ONE PIECE LOST. PULLEY MOVED OUT OF POSITION, STRESSING BELT AND CAUSING NOISE. REMAINING PIECE OF THE KEY WAS EMBEDDED AND FUSED INTO THE CRANK SHAFT. PULLEY KEY IS $ PART. OBVIOUSLY, NOT DURABLE ENOUGH FOR CRITICAL ENGINE PART, WHICH WHEN FAILS CAN RUIN THE ENTIRE ENGINE. EVEN 500 X THE $ COST WOULD BE WORTH HAVING TITANIUM OR TUNGSTEN STEEL PART THAT WOULD NEVER FAIL. TOYOTA IS CUTTING CORNERS, SACRIFICING QUALITY IN THE NAME OF PROFIT. I RISKED HAVING TO REPLACE THE ENGINE -- A $9,000 CONSIDERATION. (3) FORTUNATELY OLD MILL TOYOTA (OMAHA, NEBRASKA. WAS ABLE TO REMOVE THE FUSED PART AND SAVE THE ENGINE. A PROPERLY ENGINEERED PART, EVEN AT MUCH GREATER COST, WOULD HAVE PROTECTED ME FROM THIS RISK.*AK

VEHICLE STALLS/QUITS WHEN BRAKING, USUALLY BETWEEN 0 AND 10 MPH. STARTED AFTER HAVING VEHICLE FOR 2 WEEKS. DEALER FIRST VISIT, THEY COULD FIND NO PROBLEMS. SECOND VISIT, CHANGED THROTTLE BODY, DID NOT SOLVE PROBLEM. SAID IT WAS PART OF A GROUP THAT NEEDS NEW COMPUTER, THAT DID NOT HELP EITHER, SAID IT MAY BE THE TRANSMISSION. PROBLEM STILL NOT SOLVED. TOYOTA TECH LINE TOLD THE LOCAL DEALER IT MUST BE A FLUKE JUST GIVE IT BACK TO THE CUSTOMER (ME). I GIVE A LOT OF CREDIT TO THE LOCAL DEALER SERVICE PERSONNEL, THEY TOLD ME THIS AND TOLD ME IT WAS UNSAFE TO DRIVE. THEY ARE WORKING THE PROBLEM AND GAVE ME A LOANER CAR.
