NHTSA Complaint #10204424 — 2002 TOYOTA CAMRY

AT ABOUT 105,000 MILES ON MY 2002 CAMRY V6, THE CAR EXPERIENCED HESITATING DRIVING WHILE DRIVEN AT SPEEDS ABOVE 40 MPH WHEN REMOVING SLIGHTLY THE FOOT FROM THE THROTTLE PEDAL. THE CAR IS BUCKING BACKWARD AND FORWARD FOR INDEFINITE TIME UNTIL THE THROTTLE PEDAL IS FULLY DEPRESSED OR FULLY PRESSED. THIS IS AN UNSAFE SITUATION SINCE ON THE HIGHWAY THE SPEED CANNOT BE DECREASED OR INCREASED ANY TIME. NOTIFIED DEALER AND TOLD THAT THIS CANNOT BE IDENTIFIED SINCE THERE IS NO ERROR CODE GENERATED (NO CHECK ENGINE LIGHT ON). REPLACED ALL SPARK PLUGS AT 108,000 MILES ON AUG 24, 2007. PROBLEM NOT SOLVED. SPOUSE NOTICED INCREASED BUCKING WHILE DRIVING DOWN HILL. WENT BACK TO THE DEALER. PERFORMED TEST DRIVE WITH TECHNICIAN IN THE CAR AND THE DIAGNOSE SYSTEM HOOKED TO THE CAR'S COMPUTER. DETECTED SOME MISFIRES ON CYLINDERS 5 AND 6. REPLACED SOLENOID IGNITION PACKS FOR CYLINDER 5 & 6 AND TEST DROVE AGAIN. PROBLEM NOT SOLVED. TECHNICIAN CONCLUDED THAT FUEL INJECTORS ARE CLOGGED. PERFORMED FUEL INJECTORS PURGE (CLEANING). PROBLEM NOT SOLVED. TECHNICIAN RECOMMENDED TO REPLACE ALL FUEL INJECTORS AND SOLENOID IGNITION PACKS. CAR WAS MAINTAINED PROPERLY DURING THE OWNERSHIP. OIL & FILTER CHANGED EVERY 3000 MILES, REPLACED AIR FILTER EVERY 30,000 MILES, REPLACED TIMING BELT AND BELT TENSIONERS AT 87,000 MILES, REPLACED WATER PUMP AT 87,000 MILES, FLUSHED TRANSMISSION FLUID AT 87,000 MILES. FROM READING VARIOUS CUSTOMERS COMPLAINTS, IT APPEARS TO BE A TRANSMISSION PROBLEM BUT DEALER DID NOT MENTION ANYTHING ABOUT IT. *JB
