LEXUS Complaints

OWNER OF A NEWLY ACQUIRED '00 LX470 FROM TOYOTA/LEXUS. WHEN I PURCHASED THE CAR, IT PASSED SAFETY AND MECHANIC INSPECTION. AFTER OWNING FOR LESS THAN 4 MONTHS, I WAS DRIVING HOME ON STREET ROADS. THE ABS LIGHT COMES ON SUDDENLY, AND I HEAR A HIGH-PITCHED BEEPING NOISE FROM THE DASH. WITHIN 5 MINUTES OF DRIVING, I AM MOVING ABOUT 30 MPH WHEN THE BRAKES GO OUT-COMPLETELY. AS IN, PEDAL TO THE FLOOR WITH NO SLOWING. WAS FORCED TO BRING THE VEHICLE TO A STOP WITH THE EMERGENCY BRAKE, THANKFULLY WITH NO INJURIES OR CRASH. WENT TO GET A PROFESSIONAL INSPECTION AND WAS INFORMED THAT MY BRAKE MASTER CYLINDER/ACTUATOR HAD FAILED. THIS REPAIR IS VERY COSTLY, AND HAS SO FAR AMOUNTED TO NEARLY 5K TO FIX. UNSURE AS TO HOW TOYOTA HAS NOT RECEIVED CRITICISM FOR THIS POTENTIAL DANGER YET. *TR

HI THERE. HAVE BEEN A LATER OWNER OF A '00 LX470 WITH ROUGHLY 250K MILES. EARLY ON IN MY OWNERSHIP--WITH THE VEHICLE IN MOTION AND NO PRIOR WARNING-- THE ABS LIGHT COMES ON AND A LOUD BEEPING NOISE STARTS. WITHIN 5 MINUTES OF DRIVING, THE BRAKE PEDAL SUDDENLY GOES DEAD (PUSHES ALL THE WAY TO THE FLOOR), AND I WAS FORCED TO BRING THE CAR TO A SAFE STOP WITH THE EMERGENCY BRAKE. THE CURRENT REPAIR FOR THIS HAS BEEN COSTLY AND DIFFICULT--WITH A PROFESSIONAL SHOP INSPECTION INFORMING ME THAT MY MASTER CYLINDER/ACTUATOR HAS FAILED. THANKFUL NO DAMAGE WAS CAUSED TO OTHER VEHICLES. *TR

ON 9/13/2019 I EXPERIENCED A LOSS OF BRAKING POWER WHILE APPLYING BRAKES ON AN UNEVEN/POTHOLED CITY ROAD SURFACE WHILE APPROACHING A STOP WITH VEHICLES IN FRONT OF ME. THIS LOSS OF BRAKING POWER NEARLY RESULTED IN COLLISION. THE LOSS OF BRAKING POWER HAS HAPPENED NUMEROUS TIMES, BUT UNTIL NOW HAS NOT RESULTED IN A POTENTIALLY HAZARDOUS SITUATION. I DISCOVERED THAT DRIVERS OF BOTH THE CT200H AND PRIUS INDICATE LOSS OF BRAKING POWER WHEN APPLYING BRAKES ON UNEVEN SURFACES SUCH AS POTHOLES, SPEED BUMPS, OR MANHOLES THAT ARE NOT LEVEL WITH THE SURROUNDING ROAD SURFACE. THIS LOSS OF POWER IS OFTEN REPORTED AS ACCELERATION, THOUGH THE MORE LIKELY EXPLANATION (SEE ATTACHMENT) IS THAT DECELERATION IS INTERRUPTED DUE TO SLOW HANDOFF OF REGENERATIVE BRAKING TO FRICTION BRAKING. PREVIOUS REPORTS OF BRAKING ANOMALIES HAVE BEEN FILED WITH NTSB FOR THE LEXUS CT200H, WHICH USES THE SAME REGENERATIVE BRAKING SYSTEM AS THE TOYOTA PRIUS. A DRIVER WHO COLLECTED DATA REGARDING THIS ISSUE STATES: "THE SPEED SENSOR DATA FROM EACH WHEEL ALSO COMES AT ABOUT 60 HZ. ONE WOULD THINK WITH THIS KIND OF DATA RATE THE SYSTEM SHOULD BE ABLE TO ADD IN FRICTION BRAKING FAST ENOUGH (AFTER GOING OVER A BUMP WHILE BRAKING AND REDUCING REGEN BRAKING), SAY IN A SMALL FRACTION OF A SECOND, SO THAT THE DRIVER WON'T HAVE TO EXPERIENCE THE MANY SECONDS OF SENSATION OF LOSS OF BRAKING, IF TOYOTA BOTHERED TO REFINE THE ALGORITHM." A REVIEW OF BRAKING RELATED INCIDENT REPORTS FOR BOTH THE TOYOTA PRIUS AND LEXUS CT200H MAY PROVIDE ADDITIONAL INSIGHT INTO THE FREQUENCY AND SEVERITY OF THE LOSS OF ASSISTED/FRICTION BRAKING ON UNEVEN ROAD SURFACES. SEE ATTACHED ACCELEROMETER DATA.

THE TRUNK LATCH RUBBER BOOT MELTED. POSSIBLE ELECTRICAL ISSUE. THE RUBBER FEELS LIKE SOFT TAR & LEAVES MARKS THAT ARE QUITE DIFFICULT TO WASH OFF. CAR LOCATION IS NOT ONE OF THE HOTTER STATES. LOOKS LIKE A MALFUNCTION OF ELECTRICAL WIRES...BEHICLE WAS STATIONARY WHEN DISCOVERED, NOT POSITIVE IF OCCURRED WHILE IN MOTION OR NOT.

ON SEPTEMBER 11,2019, AT ABOUT 4:15 P.M I WAS DRIVING ON THE SOUTHBOUND ON RAMP ONTO I-25 AT THE WINDSOR, COLORADO ON RAMP (EXIT 262). I WAS TRAVELING APPROXIMATELY 50 TO 55 MPH WITH THE SUNROOF OPEN/RETRACTED. I WAS TRAVELING STRAIGHT, NOT TURNING, WHEN IT OCCURRED. . I HEARD A LARGE BOOM COME FROM THE ROOF AND THEN THE SOUND OF SAFETY GLASS CRACKING. I PULLED OVER AND FOUND THE SUNROOF GLASS HAD SHATTERED. I COULD NOT FIND ANY ROCKS OR OTHER DEBRIS NOR COULD I SEE ANY SCRATCHES OR MARKS FROM ANY FOREIGN OBJECT HIRING IT IF THAT COULD HAVE CAUSED IT. THE GLASS ROOF WAS RETRACTED INTO THE OTHER PART OF THE ROOF AT THE TIME HOWEVER SO I DO NOT SEE HOW SOMETHING COULD HAVE HIT IT WITH THE ROOF METAL ROOF PROTECTING IT FROM ANY OUTSIDE OBJECTS AT THE TIME OF BREAKAGE. THERE WERE NO INJURIES AS THANKFULLY IT WAS RETRACTED. IT DID OCCUR WHILE TRAVELING ON AN INTERSTATE WITH INTERSTATE SPEEDS AND COULD HAVE CAUSED INJURY FROM FALLING GLASS AND/OR CAUSE AN ACCIDENT. I HAVE ATTACHED A PHOTO OF THE BROKEN GLASS.

NOTICED HUGE PUDDLE OF OIL UNDER CAR AFTER PARKING IN DRIVEWAY. HAD CAR TOWED TO LEXUS DEALER. FOUND OIL COOLER RUBBER HOSE RUPTURED. REPLACEMENT LINE IS NOW CONSTRUCTED OF METAL. THIS APPEARS TO BE A COMMON ISSUE ON THESE VEHICLES AS EVIDENCED IN VARIOUS LEXUS FORUMS.

AT RANDOM TIMES WHEN DRIVING OUR CAR, THE ABS, VSC AND BRAKE WARNING LIGHTS COME ON ON THE DASHBOARD. WHEN THIS HAPPENS THE ABS SYSTEM BECOMES INOPERATIVE, AND THE FRONT BRAKES CAN EASILY LOCK UP DURING MODERATELY HEAVY BRAKING. WE BELIEVE TOYOTA HAS PURPOSELY DESIGNED THE SYSTEM TO DISABLE THE ABS FUNCTIONALITY WHEN THERE IS A POSSIBLE PROBLEM DETECTED IN THE ABS ACCUMULATOR. THAT DOES NOT SEEM LIKE A GOOD IDEA. THE WARNING LIGHTS SOMETIMES GO OFF FOR A WHILE (A FEW DAYS SOMETIMES) AND THEN RETURN AT RANDOM TIMES AND DURING VARIOUS DRIVING CONDITIONS. THE WARNING LIGHTS USUALLY COME ON WHEN DRIVING AT MODERATE SPEED, AND WHEN NOT TOUCHING THE BRAKE PEDAL. FROM OUR RESEARCH IT SEEMS LIKE THIS ISSUE IS WELL KNOWN AND DOCUMENTED, AND TOYOTA SOMETIMES REPAIRS THE BRAKE SYSTEM AT NO COST, HOWEVER IT SEEMS LIKE THIS SHOULD BE A REQUIRED RECALL. OUR CAR HAS LOW MILES FOR THE YEAR, ONLY 86K. WE HAVE ASKED FOR HELP FROM LEXUS HOWEVER HAVE NOT GOTTEN ANY RESPONSE SO FAR.

TL* THE CONTACT OWNS A 2017 LEXUS GS 350. WHILE DRIVING 15 TO 20 MPH, ANOTHER VEHICLE FAILED TO STOP AND CRASHED INTO THE CONTACT'S VEHICLE. THE DRIVER'S AIR BAG AND FRONT PASSENGER AIR BAG FAILED TO DEPLOY. THERE WERE NO INJURIES. THE FIRE AND POLICE DEPARTMENTS WERE PRESENT, AND POLICE REPORT NUMBER: 180107 WAS FILED. THE VEHICLE WAS TOWED TO A COLLISION CENTER. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOTIFIED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 24,700. THE VIN WAS UNKNOWN.

MY PASSENGER AIRBAG COMPARTMENT ON FRONT DASH HAS BEEN SLOWLY BEEN LIFTING AND SEPARATING THOUGH THE CAR HAS NEVER BEEN IN AN ACCIDENT. IS THE AIRBAG GOING TO IMPLODE ONE DAY ON A PASSENGER WITHOUT US KNOWING? IT IS LOOKING SCARY BUT I SEE THERE IS NO RECALL.

TL* THE CONTACT OWNS A 2012 LEXUS RX450 HYBRID. WHILE DRIVING VARIOUS SPEEDS, THE CONTACT HEARD A STRANGE AND CONSTANT BUZZING NOISE THROUGHOUT THE VEHICLE. THE CONTACT STATED THAT SHE BELIEVED HER EX-BOYFRIEND HACKED INTO HER VEHICLE. THE VEHICLE WAS TAKEN TO LEXUS OF WESTMINSTER (13590 BEACH BLVD, WESTMINSTER, CA 92683, 714-702-1849) WHERE SHE WAS INFORMED THAT THEY WOULD HAVE TO TAKE APART THE VEHICLE FOR DIAGNOSTIC TESTING. THE TESTING WOULD BE AT THE CONTACT'S EXPENSE. THE MANUFACTURER WAS CONTACTED AND DID NOT ASSIST. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 70,000.
