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

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Lexus RX 350h verdict →
