2004 LEXUS RX330 Electrical System Problems

CRUISE CONTROL WILL NOT TURN ON, CANNOT OPERATE WHILE CAR IS IN MOTION ON THE HIGHWAY. 12

MY ELECTRICAL WIRING HAS A HUGE ISSUE. I AM CONFIDENT THIS HAS TO BE A HAZARD OF SOME KIND! A FEW YEARS AGO I STARTED HAVING ISSUES LOCKING/UNLOCKING MY CAR DOORS WITH THE KEY FOB. ONLY ONE OR TWO DOORS WOULD LOCK/UNLOCK ON COMMAND. AFTER RESEARCH I FOUND THIS TO BE A POSSIBLE ACTUATOR PROBLEM. LEXUS ESTIMATED THE COST TO BE $700/ACTUATOR (PER DOOR). WITHOUT HAVING THE ACTUATORS FIXED JUST YET, A COUPLE OF DAYS PASSED AND I NOTICED MY TAIL LIGHT WENT OUT. THE NEXT DAY A HEADLIGHT WENT OUT. I VISITED OUR LOCAL ADVANCED AUTO WHERE THEY REPLACED MY HEADLIGHT AND ONLY 'WIGGLE' REAR TAILLIGHT RESULTING IN IT TO WORK AGAIN. UPON LEAVING, I NOTICED THAT ALL OF MY DOOR LOCKS WORKED AGAIN! THIS BULB ADJUSTMENT EFFECTED THE OTHER ELECTRICAL ITEMS. MANY MONTHS LATER, I HAVE REPLACED A HANDFUL OF BULBS AND HAD TO 'WIGGLE' TOO MANY BULBS...

MY KEY TO MY 2004 LEXUS 330SUV HAS BROKEN 3 TIMES. ONCE IT BROKE IN THE IGNITION. I HAVE USED MY KEY IN AN ORDINARY WAY. LEXUS HAS REPLACED THE KEYS BUT AT MY EXPENSE. I BELIEVE THERE IS SOMETHING FAULTY WITH THE IGNITION AND/OR THE KEY ITSELF. THOUGH I HAVE NOT BEEN INJURED, IT IS POSSIBLE THE KEY COULD BREAK WHILE DRIVING AND CAUSE INJURY. I REPLACED THE KEY IN 2006, 2008 AND MOST RECENTLY IN JUNE 2011. I HAVE PAID $220 EACH TIME IN 2006 AND 2008. IN 2011, I CONTACTED LEXUS INTERNATIONAL AND WAS REIMBURSED $95 FOR THE $110 PLASTIC CASING I GOT FOR THE NEW KEY AS THEY TRANSFERRED THE WIRELESS PORTION INSTEAD OF REPLACING THE ENTIRE KEY. I THINK THAT THEIR KEY AND LOCK MECHANISM SHOULD BE EXAMINED, THAT DEALERSHIPS SHOULD BE REQUIRED TO INDICATE HOW MANY OF THESE TYPES OF REPAIRS ON THIS VEHICLE...

TL*THE CONTACT OWNS A 2004 LEXUS RX330. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 30-40 MPH THE VEHICLE LUNGED FORWARD VIOLENTLY AND IT ALSO STALLED WHEN TRYING TO ACCELERATING FROM A STOP SIGN. THE VEHICLE WAS INSPECTED BY A DEALER WHO INFORMED THE CONTACT THAT SHE NEEDED TO RESET THE COMPUTER AND THAT IT WOULD TAKE TIME FOR THE VEHICLE TO LEARN HER DRIVING HABITS. THE COMPUTER WAS RESET; HOWEVER, AND THE PAUSING AND LUNGING FORWARD CONTINUED TO OCCUR. THE FAILURE MILEAGE WAS APPROXIMATELY 42,000.

WHEN I SLOW MY LEXUS LS-430 DOWN TO ABOUT 10 - 15 MPH THEN ATTEMPTED TO ACCELERATE LIGHTLY, THE CAR WILL OFTEN NOT RESPOND TO THE THROTTLE. I'LL DEPRESS THE ACCELERATOR FURTHER AND EVENTUALLY THE CAR WILL RESPOND BY DOWN SHIFTING INTO A LOWER GEAR AND ACCELERATING VERY RAPIDLY. I HAVE CONTACTED LEXUS AND THEY HAVE STATED THAT THIS IS A RESULT OF THE "FLY-BY-WIRE" DESIGN OF THE THROTTLE AND THAT I'LL EVENTUALLY LEARN TO COMPENSATE. THEY STATED THAT THEY CANNOT REPROGRAM THE COMPUTER TO ELIMINATE THIS CONDITION SINCE THIS WOULD REQUIRE RECERTIFICATION FROM THE EPA AND THEREFORE IS OUT OF THE QUESTION. THIS IS A DANGEROUS SITUATION.*AK
