DRIVING OFF A STOP LIGHT AND THE CAR JUST DIED. CHECK AWD - CVT - HYBRID SYSTEM WARNING LIGHTS WENT ON . TOWED TO DEALER NEXT MORNING AND THEY CALLED TO SAY LUCKY IT IS UNDER WARRANTY ( I HAVE 64000 MILES , WARRANTY IS 70 K ) AND IT NEEDS A NEW INVERTER. I HAVE NOT SEEN BILL BUT HERE IT IS $ 7 TO $ 9000 YIKES ! THIS IS A PROBLEM AS IT SHAKES MY FAITH IN LEXUS BOUGHT FROM USA TO BRING TO CANADA AND RELIED ON TOYOTA - LEXUS BRAND --- THIS SHOULD NOT BE HAPPENING AND FROM WHAT I CAN SEE THE TOYOTA LEXUS HYBRID SYSTEM NEEDS A LONGER WARRANTY !!!! I BELIEVE IT IS A FAULTY CURRENT INVERTER MADE OF PLASTIC, THEY REPLACE WITH NEWER METAL ONE. *TR

PURCHASED A CERTIFIED USED RX330 AND ONE WEEK LATER NOTICED CONDENSATION INSIDE HEADLIGHT LENSES AFTER DRIVING IN RAIN OR WASHING THE VEHICLE THAT TAKES SEVERAL DAYS TO CLEAR OUT CAUSING SEVERE REDUCED VISIBILITY WHEN DRIVING AT NIGHT. THE CONDENSATION IS AN OBVIOUS SAFETY PROBLEM BUT THE LEXUS DEALER SAID IT IS NOT COVERED UNDER WARRANTY OR ANY RECALL. I THINK LEXUS SHOULD TAKE CARE OF SUCH AN IMPORTANT SAFETY CONCERN AS LIGHTING THE HIGHWAY AHEAD.

COMPONENT: ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR SUMMARY: AT A STEADY RATE OF SPEED ON THE HWY, THE CAR SURGES AND PULLS AND IS IMPOSSIBLE TO MAINTAIN A SMOOTH RIDE. WHEN BRAKING EXPERIENCE SHORT BURSTS OF ACCELERATION. I AM CONCERNED AS THIS SEEMS TO BE LEADING TO AN INVERTER FAILURE. *TR

NO FAILURE, YET. BUT VEHICLE (LEXUS RX400H - 2006) IS A HYBRID. THERE IS A SEPARATE COOLING SYSTEM FOR THE HYBRID COMPONENTS (INVERTER, AND ELECTRIC MOTORS IN TRANSAXLE). COOLANT IS LEAKING FROM THE TRANSAXLE. IF ALL COOLANT LEAKS OUT, THE INVERTER WILL FAIL. WITHOUT THE INVERTER, THERE IS NO POWER - NO ELECTRIC STEERING, NO ELECTRIC BRAKES, AND NO MOTIVE POWER TO THE WHEELS. ADDITIONALLY, THE COOLANT MAY LEAK SOMEWHERE OR ONTO SOMETHING THAT MAY SHORT OUT OR CAUSE A FIRE. THIS IS NOT A LEAK FROM A WORN OUT COOLANT HOSE, BUT DIRECTLY FROM THE TRANSAXLE. BEING A HYBRID, THE AVAILABILITY OF ELECTRIC POWER IS ABSOLUTELY ESSENTIAL. THERE HAVE BEEN REPORTS OF INVERTERS FAILING (JUST CHECK THE LEXUS. TOYOTA AND OTHER HYBRID FORUMS) ON THE HIGHWAY AT SPEED, LEADING TO A COMPLETE LOSS OF POWER. TO THE BEST OF MY KNOWLEDGE, THERE HAVE BEEN NO INJURIES OR ACCIDENTS, BUT THE POTENTIAL IS FRIGHTENING. *TR

TL*THE CONTACT OWNS A 2006 LEXUS RX400 HYBRID (NA). WHILE DRIVING APPROXIMATELY 70 MPH, THE POWER SYSTEM SHUT DOWN SUDDENLY WITH NO POWER BRAKES OR POWER STEERING. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER WHO STATED THAT A NEW HYBRID SYSTEM NEEDED TO BE INSTALLED. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 70,000.

2006 LEXUS RX400H (AND OTHER TOYOTA/LEXUS MODELS). ANTI BACTERIAL / MOLD COATING ON A/C EVAPORATOR BEGINS SHEDDING WITH AGE/TIME AND BLOWS WHITE POWDER/DUST THROUGH VEHICLE. LEXUS SAYS IT'S ALUMINUM HYDROXIDE, AND IT'S PERFECTLY SAFE. HOW CAN IT BE SAFE TO INHALE / INGEST A FOREIGN SUBSTANCE? HAS LEXUS / TOYOTA DONE ANY STUDIES REGARDING ALUMINUM HYDROXIDE. IF IT'S SAFE, WHY DOES LEXUS / TOYOTA NOW OFFER (AND INSTALL IN NEW VEHICLES) AN A/C EVAPORATOR WITHOUT THE COATING? *TR

WHILE DRIVING AT HIGHWAY SPEED THE LEFT REAR QUARTER WINDOW MOLDING CAME FLYING OFF MY LEXUS 2006 RX-330. MADE A FLAPPING NOISE PREVIOUS TO COMING OFF. CHECKED ON THE WEB @ CLUBLEXUS .COM AND FOUND THIS TO BE A PROBLEM WITH A LOT OF OTHER RX OWNERS. IF YOU ARE IN WARRANTY, NO PROBLEM, BUT OUT OF WARRANTY LIKE I AM. PROBLEM IS THAT LEXUS DOES NOT SELL JUST THE MOLDING, YOU HAVE TO BUY THE ENTIRE WINDOW. THE MOLDING IS ON DOUBLE STICK TAPE ONTO THE WINDOW RUBBER SEAL. LEXUS P/N 62730-48230. *TR
