I WHEN TO A CAR WASH FACILITY AND THE ICS SENSOR WHEN CRAZY!!! (FLASHING THE WARNING LIGHT). NOW MY CAR GIVING ME A ICS MALFUNCTION. THE AUTOMATIC BRAKING DON'T WORK AND THE PARKING ASSISTANCE NEITHER. I BELIEVE THIS IS A MANUFACTURING PROBLEM DUE SAME CAR MODEL AND YEAR EXPERIENCE THE SAME BUT IT HAS DIFFERENT VIN SO THERE IS NOT A RECALL FOR MY VIN.
MY CAR (INSURED) REAR ENDED ANOTHER PARTY AT LESS THAN 10 MILES PER HOUR. THE PRE-COLLISION SYSTEM THAT IS PART OF MY CAR NEVER BECAME ACTIVE IN MY CAR AND SO I REAR ENDED THE CAR. LEXUS INSPECTED MY RX-350 AND HAVE AN UNACCEPTABLE REASON THAT IT WILL NOT WORK, UNLESS THERE IS A NOTICEABLE SPEED DIFFERENCE BETWEEN MY CAR AND THE CAR AHEAD OF ME. THE CAR WAS THE PROBLEM AND IT DID NOT WORK AND SO I REAR ENDED THE PREVIOUS CAR. MY LIGHTS WERE ALSO BROKEN AND HAD TO BE REPLACED. SOME ELECTRICAL WIRING REWORK WAS ALSO DONE.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
TL* THE CONTACT OWNS A 2017 LEXUS RX350. WHILE THE VEHICLE WAS PARKED, THE START BUTTON WAS DEPRESSED, BUT THE VEHICLE DID NOT START UNTIL AFTER THE FOURTH ATTEMPT. THE CONTACT STATED THAT THE FAILURE OCCURRED APPROXIMATELY THREE OTHER TIMES. THE CONTACT ALSO MENTIONED THAT THE FAILURE OCCURRED ONLY AFTER THE VEHICLE HAD NOT BEEN DRIVEN FOR TWO OR MORE DAYS. IN ADDITION, THE 'CONTACT YOUR DEALER SOON' MESSAGE APPEARED ON THE MESSAGE CENTER. THE VEHICLE WAS TAKEN TO THE DEALER (LEXUS OF BIRMINGHAM, 1001 TOM WILLIAMS WAY, IRONDALE, ALABAMA 35210), BUT THE FAILURES COULD NOT BE DUPLICATED. THE DEALER INQUIRED IF THE BRAKE PEDAL WAS DEPRESSED SIMULTANEOUSLY WHEN THE START BUTTON WAS DEPRESSED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 9,000.
CAR IS UNSAFE AS YOU NEVER KNOW HOW IT WILL REACT WHEN YOU PRESS THE GAS PEDAL. OFTEN TIMES YOU PRESS IT TO ACCELERATE A LITTLE AND IT'S LIKE YOU LET OFF THE GAS ENTIRELY. YOU THEN HAVE TO AGGRESSIVELY PRESS THE PEDAL DOWN TO WHICH IT REACTS WILDLY. SOMETIMES YOU BARELY TOUCH THE PEDAL AND IT TAKES OFF BUT MOST TIMES YOU GET LITTLE TO NO RESPONSE. ACCELERATION DOES NOT REACT LINEAR IN CONJUNCTION WITH THE GAS PEDAL. THIS ISSUE ONLY EXISTS AS THE CAR LEARNS YOUR DRIVING. CAR DRIVES FINE WHEN THIS LEARNING IS CLEARED FROM COMPUTER MEMORY. LEXUS SAYS THIS IS NORMAL BUT HOW CAN ROLLING OUT INTO TRAFFIC AND WAITING TO GET HIT BE NORMAL? THEY WON'T RELEASE OR UPDATE THE PROGRAMMING BECAUSE THIS WOULD THEN AFFECT THE MPG NUMBER THEY ARE CLAIMING. TO BE CLEAR, GENTLY START TO PULL OUT TO MERGE INTO TRAFFIC, PRESS GAS PEDAL TO GET OUT OF THE WAY OF CARS COMING AT YOU AND NO REACTION FROM CAR. BIG DEAD SPOT IN THE PEDAL RANGE . NOW CARS ARE CLOSING IN SO YOU HAVE TO STOMP THE GAS TO SAVE YOURSELF. HAPPENS CONTINUOUS ONCE CAR LEARNS YOUR DRIVING. THIS IS ALL IN THE NORMAL MODE DEFAULT SETTINGS FOR POWERTRAIN.

From owner reports, verbatim
VEHICLE ROLL OVER DRIVER AFTER BEING PLACED IN PARK AT THE RESIDENCE CAUSING FATAL INJURIES. DRIVER REVERSED OUT OF GARAGE AND EXITED VEHICLE. INSPECTION AT THE SCENE BY THE SHERIFF'S OFFICE REVEALED THE VEHICLE WAS IN PARK BACKED AGAINST SOME TREES. THIS VEHICLE IS EQUIPPED WITH A AUTOMATIC TRANSMISSION AND A AUTOMATIC EMERGENCY BRAKE. THE GEAR SHIFT LEVER CAN BE PLACED BETWEEN PARK AND REVERSE AND NOT MOVE. IF THE GEAR SHIFT LEVER IS MOVED SLOWLY FROM DRIVE TO PARK OR REVERSE TO PARK THE AUTOMATIC EMERGENCY BRAKE DOES NOT ENGAGE THIS CONDITION IS VERY DANGEROUS.
THE TRANSMISSION ON THIS VEHICLE IS BAD! THE DEALER KEEPS SAYING IT'S NORMAL IN THE LEARNING PHASE, BUT THERE IS NO WAY ALL OF THIS SPUTTERING AND HESITATION IS NORMAL FOR ANY VEHICLE, LET ALONE A LUXURY ONE. THE TACHOMETER JUMPS, JERKS AND SPUTTERS AS WELL IF YOU WATCH IT. THE PRE-COLLISION BREAK SYSTEM IS ALSO SEVERELY FLAWED. IT HAS BRAKED SO HARD THAT IT SCREETCHED AND NO ONE WAS EVEN AROUND ME!!!!! THIS CLEARLY ALMOST GAVE ME A HEART ATTACK THREE TIMES NOW. IT HAS HAPPENED TWICE WHEN SLOWLY BACKING OUT OF A PARKING SPOT, AND ONE TIME WHILE DRIVING DOWN THE STREET AT A NORMAL RATE OF SPEED AND NO ONE WAS AROUND ME AT ALL.
