ON MY WAY HOME, CHECK ENGINE LIGHT COMES ON, THEN STARTS BLINKING. GOT HOME AND FIND OUT THE OILS ALL GONE AND DEAD CAR. MY MECHANIC SAYS THE OIL LINE HAS A RECALL AND THAT IT BROKE LETTING ALL OIL OUT.
WE ARE THE ORIGINAL OWNERS OF THIS CAR. WE HAVE CHANGED THE OIL AND OIL FILTER AS REQUIRED BY TOYOTA. NEVER HAD A PROBLEM UNTIL THE LAST FEW MONTHS. ALL OF A SUDDEN WE ARE GOING THROUGH MULTIPLE QUARTS OF OIL BETWEEN OIL CHANGES. WE NEVER HAD TO ADD OIL PREVIOUSLY. SEARCHING ONLINE I SEE THIS IS A KNOWN PROBLEM. I ALSO READ THAT TOYOTA WON'T FIX IT. WANTED TO ADD MY NAME TO THE LIST OF COMPLAINTS IN THE HOPE THAT TOYOTA WILL BE FORCED TO FIX THIS ISSUE.

TL* THE CONTACT OWNS A 2007 TOYOTA HIGHLANDER HYBRID. WHEN APPLYING PRESSURE TO THE BRAKE PEDAL, THE ENGINE WOULD OCCASIONALLY REV MAKING BRAKING MORE FORCEFUL. HE SPECULATED THAT THE ENGINE CONTROL SYSTEM FAILED. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR INSPECTION. THE TECHNICIAN STATED THERE WAS NO DIAGNOSTIC TESTING EQUIPMENT AVAILABLE TO DETECT THE MALFUNCTION. THE FAILURE MILEAGE WAS 40,000. THE CURRENT MILEAGE IS 42,000.

UPDATED 03/22/10.*JB THE CONSUMER STATED THE PROBLEM HE EXPERIENCED WAS NOT DUE TO A STUCK ACCELERATOR, BECAUSE THE ACCELERATOR PEDAL ALSO RUNS THE HYBRID MOTOR. THE HYBRID MOTOR IS NOT ACCELERATING THE VEHICLE LIKE THE GAS ENGINE. IF THE GAS PEDAL WAS THE PROBLEM, THE VEHICLE WOULD STILL RUN AWAY IN ELECTRIC MOTOR. THEREFORE, IT IS DEFINITELY AN ENGINE PROBLEM, NOT AN ELECTRIC MOTOR OR ELECTRIC GENERATOR. AND IT IS SOMETHING THAT CONTROLS THE ENGINE AND THE HYBRID ELECTRIC MOTOR.
