NHTSA Complaint #10542341 — 2007 LEXUS ES350

I PURCHASED THE CAR WITH A CERTIFIED PRE-OWNED WARRANTY AS I DID WITH TWO OTHER LEXUS THAT I HAVE OWNED. SHORTLY AFTERWARD I NOTICED THAT WHEN I SLOWED DOWN TO STOP AT THE TOP A STEEP HILL THE CAR WOULD SUDDENLY LURCH FORWARD AND I HAD TO APPLY THE BRAKE TO STOP THE CAR. I WENT TO THE DEALER AND TOOK A RIDE WITH THE SERVICE MANAGER WITH A LAPTOP ATTACHED TO THE CAR. I DUPLICATED THE PROBLEM. THE DEALER SAID THE PROBLEM WAS THAT THE TRANSMISSION HAS A PROBLEM SHIFTING FROM 4TH TO FIRST GEAR .THE DEALER APPLIED SOME COMPUTER UPDATES. AFTERWARD, THE PROBLEM LURCHING WAS STILL THE SAME. I TOOK THE CAR BACK TO LEXUS AND DUPLICATED THE PROBLEM WITH THEM AGAIN. THEY DID ANOTHER UPDATE BUT THE PROBLEM WAS STILL THE SAME. THE DEALER BROUGHT IN A TECH REP FROM LEXUS. THEY DECIDED THAT THE PROBLEM WAS NOT SIGNIFICANT ENOUGH FOR THEM TO REPLACE THE TRANSMISSION OR THE COMPUTER THAT CONTROLS THE TRANSMISSION. I STILL HAVE THE SAME IRRITATING PROBLEM. ALTHOUGH THE CAR IS STILL UNDER THE CERTIFICATION WARRANTY, IT WILL RUN OUT SOON.
