TCM, ECM Problems

2005 Lexus ES 330 4dr Sedan (3.3L 6cyl 5A)


My wife is principal driver but in January 2006 I drove the ES330 4,000 miles from northern IN to Key West and return. The engine and transmission fails to respond to throttle commands and the vehcle does not downshift to third gear when needed. With the pedal to the metal at 60 mph it takes forever to get back up to 70/75 mph. Same problem on entrance ramps. Trying to merge in 4th or 5th gear at 2,000 rpm will not get you out of the way of 18 wheelers. Car is at the dealer now. Have reported this to NHTSA as a safety issue. 25 mph not too impressive. GM can do 30 mpg with 3.8 L.

Best Features

Quietest vehicle I have ever driven

Worst Features

Change HVAC and audio displays from LCD to LED. Iluminate tach needle during cranking to be able to see that engine has started.
