2007 Lexus RX Electrical System Problems

Put key into ignition port and heard and felt a klunk. Key was then freely moving and connecting to nothing inside the ignition chamber. So vehicle would not turn over at all. Had towed to town closer to home. And Currently having towed to mechanic shop for further evaluation. The only symptom the car was having previously was a mysterious scratching sound coming from what sounded like the right side of the hood near the firewall. Took to mechanic and he drove the car and heard the sound but could not pin point it, said nothing was scrubbing the fan or anything else he could see. And to bring it back if it got worse. Never did we think it was the starter nor the ignition chamber. The only way to know now....is to replace it and see if that noise is still there. There were no other warnings. The danger in this is being stranded. Still needs to be evaluated by mechanic.

Dear all I bought this car in 2016. It was imported from USA to UAE now registered in Abu Dhabi. The car completely stalled while stopping at inclined position for about 10 minutes in front of a security barrier. READY lasts for less than 5 seconds and disappear. The car could not be started again for three month. Local dealer [XXX] Indicated they are not handling imported vehicles except from GCC region. A local repair company identified the problem by error code P0A78 but told the repair cost will be heavy. What could I do with my car which still under recall in USA for repair of the same INVERTER problem? Appreciating your help. Best regards [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Water gets into the body of the vehicle over time. Came outside one day after rain and my passenger carpet was SOAKED all my windows were up and my complex don’t get flooded. Car smells like mildew in cabin! Middle of July I came outside and all the lights were on the dash, no rain the previous day or during, and car wouldn’t start. Took it to the dealership and they can’t explain how water got into my car but magically the sunroof drain was clogged with water.

THE PASSENGER SIDE OUTSIDE MIRROR EXPLODED SENDING GLASS SHARDS AND CAUSTIC LIQUID ON THE SIDE WINDOW AND PAINTED SURFACE OF THE DOOR AND FENDER AREAS. EXPLOSION WAS SPONTANEOUS WITH NO APPARENT CAUSE, AMBIENT TEMP 50'S, NO BIRD STRIKE, THROWN ROCK OR PROJECTILE. EXPLOSION WAS GUN-SHOT LOUD. VEHICLE WAS BEING DRIVEN AT 10MPH ON NEIGHBORHOOD STREET. NO OTHER MOVING CARS AT THE TIME AND THE MIRROR DID NOT COME IN CONTACT WITH ANYTHING. INTERNET SEARCH OF EXPLODING MIRRORS REVEALED SIMILAR COMPLAINTS FROM OWNERS OF MANY BRANDS OF VEHICLES. CAUSE OF THE EXPLOSION HAS TO DO WITH THE DIMMING FUNCTION IN THE MIRRORS OF LATE MODEL VEHICLES. THE EXACT MECHANISM CAN ONLY BE GUESSED. THE CAUSTIC LIQUID MIGHT, UNDER PRESSURE AND ELECTRICAL CHARGE TEND TO BEND THE MIRROR IN SOME WAY, AND AFTER SOME TIME, FAIL CATASTROPHICALLY. THIS THEORY WAS CONFIRMED BY A STATE INSPECTION OFFICER WHO HAS HEARD OF SIMILAR PROBLEMS WITH LATE MODEL YEAR SIDE MIRRORS WITH DIMMER FUNCTION. COST OF REPAIR FROM ONE ESTIMATE WAS $1300 FOR A NEW MIRROR AND REPAINTING OF THE MARRED SURFACES. LEXUS HAS REFUSED OUR REQUEST TO REIMBURSEMENT OR EVEN TO CONSIDER THAT THE MIRROR COULD HAVE EXPLODED. I WOULD ALSO ADD THAT HAD THERE BEEN A PASSENGER SEATED AND THE WINDOW DOWN, GLASS SHARDS AND CAUSTIC LIQUID WOULD SURELY HAVE STRUCK THE PASSENGER IN THE FACE. THERE IS A PROBLEM WITH THESE MIRRORS AND A RECALL IS CLEARLY IN ORDER.

I HAVE NOTICED FOR SOMETIME WHILE DRIVING WITH MY WIFE.THE AIRBAG LIGHT ON THE PANEL FOR THE PASSENGER SIDE DOES NOT COME ON. SOMETIMES IT COMES ON AFTER WE HAVE BEEN DRIVING FOR A WHILE.I FIGURE THE AIRBAG WILL NOT WORK IF WE WERE IN AN ACCIDENT.I HAVE NO IDEA HOW MANY CARS COULD BE EFFECTED WITH THIS ISSUE.

LOST POWER ON HIGHWAY MY RX350 (2007) LOST POWER GOING 65 MPH ON A HIGHWAY, AND BEGAN TO SLOW DOWN QUICKLY. WITH A TRUCK ON ONE SIDE AND ANOTHER BARRELING DOWN MY BEHIND, I TRIED TO ACCELERATE BUT THE VEHICLE BEGAN TO SHUDDER AND SHAKE VIOLENTLY! BY SOME MIRACLE, I MANAGED TO SWERVE TO THE SHOULDER ACROSS 2 LANES, AND AVOIDED GETTING HIT BY INCHES! GOT THE VEHICLE TO THE LEXUS DEALER AND THEY FOUND OUT THAT IT WAS A PREMATURE IGNITION COIL FAILURE - THE VEHICLE HAS ONLY ABOUT 42000 MI ON IT. ASKED LEXUS CORPORATE TO: 1) DO A FULL INVESTIGATION SO AS TO PREVENT SIMILAR LIFE THREATENING SAFETY FAILURES, AND 2) REIMBURSE THE COST OF REPAIR AT A MINIMUM LEXUS CUSTOMER SERVICE RESPONDED WITH A VERBAL OFFER TO BEAR 10% OF THE COST OF REPAIR - AND NO PROMISE OF ANY INVESTIGATION! TALK ABOUT ADDING INSULT TO INJURY. WE'D UNDERGONE A TRAUMATIC EVENT, ALMOST LOSING OUR LIVES - MY WIFE HAD STARTED SCREAMING ON THE SIDE OF THE HIGHWAY AND WOULD NOT GET BACK INTO THE VEHICLE! I REFUSED, OF COURSE, AND PAID THE ENTIRE (AND SUBSTANTIAL) BILL MYSELF. I'D LIKE ALL READERS TO BE AWARE OF THE POWER FAILURE AND BE ESPECIALLY CAREFUL OUT ON THE HIGHWAY. ALSO BE AWARE THAT THE LEXUS PROMISE OF PERFECTION SEEMS TO BE MAINLY LIP SERVICE NOWADAYS - SAFETY APPARENTLY IS NOT IN THEIR DEFINITION OF 'PERFECTION'. TO SEE SUCH A SERIOUS INCIDENT BEING TREATED SO TRIVIALLY WAS TOTALLY AT ODDS WITH THE LEXUS MISSION AND THE LEXUS PROMISE TO ITS DRIVERS. *TR

THE EXTERIOR LIFT GATE BUTTON HAS BECOME A BLACK STICKY GOOEY MESS. IT IS CONCERNING THAT AN ELECTRICAL ISSUE COULD BE MELTING THE BLACK RUBBER BUTTON. FOUND MANY OTHER CASES OF THIS WITH LEXUS AND TOYOTA SIENNA'S ONLINE. HAS SOMETHING BEEN DONE ABOUT THIS OCCURRENCE? *JS

CHECK ENGINE LIGHT CAME ON AND VSC OFF CAME ON WHILE DRIVING. VEHICLES VIBRATE VIOLENT SHORTLY AFTER. WAS DIAGNOSED BY LEXUS TECHNICIAN THAT IGNITION COIL #6 HAS FAILED. *TR

HEADLAMP CONDENSATION MAKE LIGHT ON OFF. IT IS SAFETY CONCERN. *TR

MOISTURE IN HEADLIGHTS CAUSING SPREAD OUT LIGHT BEAM AND POSSIBLE RUST/SHORT CIRCUIT IN ELECTRICAL SYSTEM. *TR

THE REAR LIFT GATE HANDLE IS MELTED AND GOOEY. WHEN I TOUCH IT TO OPEN THE REAR DOOR, I GET THIS GOOEY TAR-LIKE SUBSTANCE ON MY FINGERS. MY DEALER TOLD ME IT REQUIRES A COMPLETE REPLACEMENT OF THE DOOR'S ELECTRICAL COMPONENTS TO FIX. SEEMS UNUSUAL THAT THIS IS ELECTRICAL, BUT IF IT IS, THEN SOMETHING IS GENERATING AN UNUSUAL AMOUNT OF HEAT TO MELT THE RUBBER COVER. MY CAR IS BLACK, BUT IT IS STORED IN A GARAGE...AND THE HANDLE IS COVERED AND OUT OF THE SUN. *TR

I HAVE NOW HAD TO REPLACE 3 IGNITION COILS. I ONLY HAVE THE PAPERWORK FOR 2 TIMES, BUT EACH TIME THE CAR BEGAN TO RUN ROUGH AND THE ENGINE WENT OFF AT STOPS, AND THE ELECTRICAL SYSTEM LIGHT WENT ON. THE FIRST TIME THIS HAPPENED, WHICH I THINK WAS IN 2010, THE LEXUS TECHNICIAN SAID IT WAS A FLUKE. THE SECOND TIME (ABOVE DATE), THE LEXUS TECHNICIAN SAID HE WAS BEGINNING TO SEE A LOT OF IGNITION COIL FAILURES. THIS LAST TIME (TODAY), THE TECHNICIAN SAID REPLACING FAULTY IGNITION COILS IS NOW COMMON, AND JUST A PART OF MAINTENANCE. HE ALSO SAID SOME PEOPLE WERE CHOOSING TO REPLACE ALL 6 OF THEM AT ONCE SO THAT THEY WOULDN'T BE STRANDED AT NIGHT OR ON THE ROAD, AND TO SAVE MONEY. OBVIOUSLY, THERE'S A MAJOR PROBLEM WITH LEXUS RX350 IGNITION COILS. *TT

IDIOT/TROUBLE LIGHTS ALL COME ON INTERMITTENTLY WHILE DRIVING; NO APPARENT AFFECT OR IMPACT ON OPERATION OF VEHICLE; OTHER THAN THE ANXIETY CREATED BY THE SUDDEN APPEARANCE OF ALL THE DASH TROUBLE LIGHTS COMING ON ALL AT ONCE, FOR NO APPARENT REASON. THIS CONTINUES TO OCCUR INTERMITTENTLY WHILE THE VEHICLE IS MOVING. AFTER SHUT DOWN AND RESTARTING, THE TROUBLE LIGHTS RETURN TO NORMAL "ALL-OFF" STATUS. THIS HAS BEEN OCCURRING FOR THE LAST TWO (2) YEARS. I HAVE DISCUSSED THE CONDITION WITH TWO DIFFERENT DEALERS (COCONUT CREEK, FL AND GREENVILLE, SC), BUT THEY CANNOT DUPLICATE THE CONDITION. *TR

OUR TWO 2007 LEXUS RX-350 (AND ALL MODELS 2004-2009) HAVE ELECTROMAGNETIC FIELD NEAR THE DASHBOARD OF APPROXIMATELY 100 MILLIGUASS. THIS IS CAUSING OUR KNEES AND HAND CELLS TO DEGENERATE AS LEXUS HAS NOT DONE ADEQUATE JOB OF PROVIDING FARADAY CAGE OR SHIELDING FROM EMF. THIS READING OF 100 MILLIGUASS IS WHAT YOU FIND UNDER HIGH VOLTAGE TRANSMISSION LINES AND STUDIES HAVE LINKED 2 TO 3 MILLIGUASS TO CHILDHOOD LEUKEMIA, CANCER, HEADACHES OR CELL DENERATION. I CONTACTED LEXUS CUSTOMER SERVICE BUT THEY BRUSHED OFF OUR SAFETY CONCERN, SAYING MOST HOUSEHOLD APPLIANCES PRODUCE EMF. FOR REFERENCE, 2010 LEXUS RX-350 OR CURRENT MODEL ES-350S HAVE 15 TO 20 MILLIGUASS. THEREFORE LEXUS HAS TECHNOLOGY TO SHIELD BUT HAS DONE INADEQUATE JOB OF SHIELDING 2004-2009 LEXUS RX-350 BU ISSUING A RECALL. WE ARE VERY CONCERNED ABOUT THIS HEALTH AND SAFETY ISSUE AND NEED HELP FROM NHTSA AS YOU ARE THE ONLY ENTITY THAT CARES. *TR

ALL THE DASHBOARD INSTRUMENT WARNING LIGHTS COME ON AND STAY ON UNTIL THE ENGINE/IGNITION KEY IS TURNED-OFF. NO APPARENT MECHANICAL OR ELECTRICAL FAILURE AS INDICATED BY ALL THE DASH WARNING LIGHTS. THE SUDDEN APPEARANCE OF THE ENTIRE DASH WARNING LIGHT SYSTEM ENERGIZING IS UNNERVING TO SAY THE LEAST. THIS HAS BEEN AN ONGOING MALFUNCTION THAT THE DEALER CANNOT LOCATE OR REPRODUCE. THE MOST RECENT OCCURRENCE WAS ON APRIL 7TH AND AGAIN ON APRIL 11TH, BOTH WHILE THE CAR WAS IN MOTION AND STAYED ON UNTIL THE ENGINE WAS SHUTDOWN. THE LIGHTS DID NOT COME ON AFTER A RESTART. THE REPEATING OCCURRENCE RENDERS THE WARNING SYSTEM TOTALLY INEFFECTIVE, IN THE EVENT OF A REAL MECHANICAL OR ELECTRICAL FAILURE.
