NHTSA Complaint #11066648 — 2017 LEXUS RX350

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.
