2018 Lexus RX350

I TRIED ACCELERATING ON THE HIGHWAY (PCH IN SANTA MONICA, CA) WHILE TRAVELING FORWARD AT ABOUT 45-50 MPH, BUT THE VEHICLE HESITATED. THIS IS THE FORTH TIME THERE HAS BEEN A HESITATION IN ACCELERATION SINCE OWNING THE CAR, BUT THIS TIME THERE WAS A MESSAGE ON MY DASH. THE MESSAGE STATED THAT THERE WAS "AN OBSTRUCTION WITH THE PEDAL AND ACCELERATION WAS RETARDED." I LATER LOOKED DOWN AT THE PEDALS FELT AROUND THE THEM, BUT FOUND NOTHING OBSTRUCTING. AT THE TIME, THE VEHICLE HAD LESS THAN A QUARTER TANK OF GAS BUT NOT LOW ENOUGH FOR THE LOW FUEL WARNING TO COME ON. AFTER DRIVING ABOUT 15 MORE MILES - THE LOW FUEL WARNING CAME ON. I HAVE ALWAYS PUT PREMIUM FUEL IN THE VEHICLE AND MY WIFE DOESN'T PUT GAS IN THE VEHICLE. A RECALL WAS RECENTLY PERFORMED PERTAINING TO THE FUEL PUMP AT THE DEALER - PERTAINING TO LOW
