NHTSA Complaint #10141859 — 2005 LEXUS ES

I PURCHASED MY 2005 LEXUS ES330 IN AUGUST OF 2004 AND HAVE HAD THE TRANSMISSION ACCELERATION / DECELERATION PROBLEMS CITED HERE IN SINCE THE PURCHASE DATE. I HAVE HAD MY CAR TO THE DEALER 4 TIMES FOR REPAIR, PLUS A FIFTH VISIT WITH THE LEXUS MANUFACTURERS REPRESENTATIVE. THEY HAVE UPGRADED THE SOFTWARE AND RESET THE ECM MEMORY EACH TIME, AND STATE THAT THERE IS NOTHING MECHANICAL WRONG WITH THE CAR. I CONCUR THAT THIS IS A DEFINITE SAFETY PROBLEM, ESPECIALLY IN HEAVY TRAFFIC, DUE TO THE DELAY AND LUNGING THAT CAN CAUSE YOU TO BE REAR ENDED OR TO REAR-END SOMEONE ELSE. LUCKILY, I HAVE NOT HAD AN ACCIDENT - HOWEVER GIVEN THAT THIS PROBLEM APPEARS TO HAVE BEEN REPORTED ON THE LEXUS ES SINCE THE 2002 MODEL, I WOULD EXPECT LEXUS OR THE NHTSA TO HAVE DONE SOMETHING BY NOW. NOTE THAT I HAVE ALSO DRIVEN THE 2006 ES AS A LOANER WHILE MY CAR WAS BEING REPAIRED, AND IT TOO HAS THE EXACT SAME PROBLEM. I ESTIMATE THE NUMBER OF FAILURES AT 300, AS THAT IS THE ESTIMATED NUMBER OF DAYS I HAVE DRIVEN MY CAR SINCE I PURCHASED IT. *NM *NM
