2017 Lexus RX350

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.

AT 1800 MILES, VEHICLE STARTED TO HESITATE WHEN PRESSING ON GAS PEDAL. WHEN ACCELERATING FROM STOP, VEHICLE IS HESITATING AND STUDDERING VERY BADLY. THIS IS AFFECTING ACCELERATING AND CAUSING A SEVERE SAFETY ISSUE WHILE DRIVING. WHILE AT HIGHWAY SPEEDS, VEHICLE CONSTANTLY IS LUNGING HESITATING WHEN TRYING TO MERGE INTO TRAFFIC. THIS HAS ALMOST CAUSED 3 ACCIDENTS AS IN STOP AND GO TRAFFIC, WHEN PRESSING ON GAS TO ACCELERATE, CAR IS SHUDDERING AND NOT FINDING RIGHT GEAR. DO NOT FEEL SAFE IN CAR. FEELS LIKE CAR IS GOING TO STALL OUT !!

TL* THE CONTACT OWNS A 2017 LEXUS RX350. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE BEGAN TO HESITATE WHILE THE ACCELERATOR PEDAL WAS DEPRESSED. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO AN UNKNOWN LOCAL DEALER, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE VEHICLE WAS TAKEN TO ANOTHER DEALER (BELL LEXUS NORTH SCOTTSDALE, 18555 N. SCOTTSDALE, SCOTTSDALE, AZ 85255) WHERE IT WAS DIAGNOSED THAT THE COMPUTER SOFTWARE NEEDED TO BE UPDATED. THE CONTACT TOOK THE VEHICLE BACK TO THE UNKNOWN LOCAL DEALER AND WAS INFORMED THAT THE FAILURE COULD NOT BE REPAIRED. THE VEHICLE WAS BEING SERVICED AS A LEMON LAW VEHICLE. THE MANUFACTURER WAS NOTIFIED AND CONFIRMED THE INFORMATION PROVIDED BY THE DEALER. THE FAILURE COULD NOT BE REMEDIED. THE FAILURE MILEAGE WAS APPROXIMATELY 4,500.

IN ORDER TO START THE CAR, THE BRAKE MUST BE PRESSED. HOWEVER, IF THE CAR SITS WITHOUT USE FOR SEVERAL DAYS, THE BRAKE PEDAL CANNOT BE PRESSED DOWN AND THE CAR WILL NOT START. A WARNING LIGHT INDICATES THAT "BRAKE POWER IS LOW, STOP IN A SAFE PLACE". ATTACHED IS A PICTURE OF THE WARNING LIGHT. THE CAR CAN GENERALLY BE SUBSEQUENTLY STARTED BY EITHER WAITING SEVERAL MINUTES OR EXERTING A LOT OF PRESSURE ON THE BRAKE PEDAL, AND THE WARNING LIGHT DISAPPEARS. I'VE HAD MANY CONVERSATIONS WITH LEXUS SERVICE AND LEXUS CORPORATE OFFICE. THEY'VE SAID THAT THIS CONDITION EXISTS WITH "EVERY 2016-2018 RX 350" AND IS NOT UNIQUE TO MY CAR. THEY'VE ALSO SAID THIS CONDITION CANNOT BE REPAIRED, DESPITE THE FACT THAT THE WARNING LIGHT INDICATES IT IS DANGEROUS TO DRIVE THE CAR. LEXUS CONFIRMED THAT DESPITE THE FACT THE CONDITION OCCURS AFTER THE CAR HAS SAT FOR A PERIOD OF TIME, IT IS NOT A BATTERY ISSUE AND LIKELY OCCURS BECAUSE OF PRESSURE LOST IN THE BRAKE SYSTEM. ALTHOUGH I QUESTION LEXUS' STATEMENTS THAT THIS CONDITION EXISTS WITH EVERY CAR, IT IS DISCONCERTING THAT THEY CANNOT OR WILL NOT FIX A CONDITION THAT MAY BE DANGEROUS TO CONTINUE DRIVING, AS INDICATED BY THE CAR'S WARNING LIGHT. THIS CONDITION OCCURS REGULARLY.

WHEN ACCELERATING HEAR A LOUD GROANING NOISE AND FEEL A HESITATION IN THE GAS ACCELERATOR PEDAL. HAVE BROUGHT TO THE DEALER 3 TIMES, AS IT SEEMS TO BE GETTING WORSE. DEALER ACKNOWLEDGES THEIR IS AN ISSUE, BUT SAYS WILL NOT FIX BECAUSE THEIR IS NO RECALL. THEY SAID WILL NOTIFY US IF/WHEN LEXUS HAS A REMEDY. APPARENTLY THIS IS HAPPENING ON 2016 & 2017 MODELS. I AM WORRIED THAT MY CAR IS JUST GOING TO LOSE POWER WHEN ACCELERATING AS IT SEEMS TO BE GETTING WORSE AND LOUDER GROANING NOISE. THIS HAPPENS FIRST THING IN THE MORNING WHEN THE CAR IS COLD AND ACCELERATING BETWEEN 0 TO 20 MPH.
