2017 Lexus RX350

VEHICLE EXPERIENCED ROUGH TRANSMISSION MOSTLY BETWEEN GEAR NUMBER 2 AND 3 AFTER TAKE OFF. VEHICLE STALLED AROUND RPM 1200 - 1500 DURING NORMAL DRIVE AT HIGHWAY, THEN SUDDENLY SHIFTED FORWARD WITH EXCESSIVE FORCE. ENCOUNTERED VERY DANGEROUS SITUATIONS ON HIGHWAY ON MY RECENT TRIP. I ALMOST HIT THE VEHICLE AT THE FRONT FOR A FEW TIMES DUE TO CONSISTENT ROUGH SHIFT PATTERN. I HAVE TAKEN THIS VEHICLE TO LEXUS DEALERSHIP SEVERAL TIMES TO ADDRESS ISSUE IN THE PAST. UPDATED ECU SOFTWARE DIDN'T RESOLVE THE PROBLEM, AND ALWAYS KEEP COMING BACK. I BELIEVE THIS ISSUE COULD HAVE BEEN RELATED TO RECENT FUEL PUMP RECALL, BUT THE RECALL DIDN'T INCLUDE THE 2017 RX 350 MODELS. PLEASE INVESTIGATE FOR SAFETY ISSUE. THANK YOU.

FROM THE FIRST WEEK I PURCHASED THIS NEW 2017 LEXUS RX350, I NOTICED THAT RAPID ACCELERATION IS NOT POSSIBLE. THERE IS A MOMENTARY HESITATION AFTER DEEPLY AND RAPIDLY DEPRESSING THE ACCELERATOR. THIS IS MOSTLY NOTICED WHEN AGGRESSIVELY PULLING INTO A TRAFFIC LANE SAY, FROM A SIDE STREET OR PARKING LOT, OR WHEN ATTEMPTING TO PASS ANOTHER VEHICLE. WHEN THE ACCELERATOR IS RAPIDLY PRESSED TO THE FLOOR, THE RPM'S NEARLY RED-LINES BUT THE VEHICLE DOESN'T ACCELERATE FOR NEARLY A SECOND, WHICH SEEMS A DANGEROUSLY LONG TIME WHEN YOU'RE IN TRAFFIC. THIS IS NOT ONLY AGGRAVATING, SEEING I PAID SO MUCH FOR WHAT IS ADVERTISED AS AND SUPPOSED TO BE A HIGHLY RATED CAR BUT IS DANGEROUS THIS CAR CAN NOT ACCELERATE AS RAPIDLY AS IT SHOULD. I MADE THE DEALER AWARE OF THE PROBLEM AND HE SAID IT IS A KNOWN ISSUE WITH SOME OF THE CARS AND IT IS FIXABLE BUT CAN'T UNTIL IT IS APPROVED BY SOME GOVERNMENT AGENCY. THE CAR IS LESS THAN 6 MONTHS OLD WITH LESS THAN 6,000 MILES AND I FEEL IT IS NOT SAFE AND DON'T WANT IT ANYMORE UNLESS IT CAN BE FIXED VERY SOON.

PURCHASED NEW CAR MARCH, 2017. FAULTY ACCELERATION OCCURS FROM START TO 40MPH. THIS HAPPENS ON SIDE STREETS AND INTERSTATES. DOES NOT MATTER WHERE YOU ARE DRIVING. RAIN OR SHINE, THIS IS A DAILY OCCURANCE. WENT TO LEXUS IN CHARLOTTE, N.C. FOR THE 5TH TIME REGARDING THIS PROBLEM. MY 10,000 MILE INSPECTION WAS DUE AND THEY SAID THAT IT IS A SOFTWARE PROBLEM AND NOT SURE WHEN IT WILL BE FIXED. DID NOT OFFER ANY OTHER SUGGESTIONS. I STARTED TO SEE LEXUS REGARDING THIS PROBLEM AFTER 1 MONTH OF OWNING CAR. WORRIED ABOUT MY SAFETY AND MY PASSENGERS REGARDING THIS ISSUE WITH THE ACCELERATION. LACK OF RESPONSE FROM LEXUS IS VERY DISAPPOINTING ESPECIALLY THE AMOUNT OF MONEY I SPENT ON MY CAR.

THE VEHICLE EXPERIENCES A DANGEROUS ACCELERATION DELAY AT CERTAIN SPEEDS. THIS IS NOT A MINOR DELAY, BUT ONE THAT IS LARGE ENOUGH TO CAUSE AN ACCIDENT. WHEN PULLING ONTO AN INTERSTATE RAMP OR PASSING ANOTHER VEHICLE, THIS PROBLEM BECOMES A HUGE SAFETY CONCERN. YOU NEVER REALLY KNOW WHEN IT WILL HAPPEN, SO THERE IS NO CONFIDENCE IN THE REACTION OF THE VEHICLE. I CURRENTLY HAVE 2000 MILES ON THIS AND IT HAS BEEN A PROBLEM SINCE DAY ONE. IT SEEMS TO BE GETTING WORSE.

FAULTY ACCELERATION OCCURS WHEN TAKING OFF FROM A STOP. AROUND 2.5 RPM, A LOUD GRINDING NOISE OCCURS AS WELL AS A STALL / LAG IN THE ACCELERATION OF VEHICLE. DANGEROUS WHEN ACCELERATING FROM A STOP LIGHT AND PULLING INTO INTERSECTION, VEHICLE STALLS AND THEN SOMETIMES SURGES FORWARD. COMPLAINED TO DEALER SINCE DAY 1 OF PURCHASE. IT SEEMS TO BE GETTING WORSE AND WORSE. I HAVE CONTINUALLY BEEN TOLD THAT LEXUS HAS NOT DEVELOPED A SOLUTION AS OF YET. SO NO SOLUTION....THIS IS A $60K VEHICLE AND IT IS VERY DANGEROUS WHEN TRAVELING BETWEEN 0 AND 35ISH.

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.
