One problem related to engine stall has been reported for the 2006 Lexus ES330. The most recently reported issues are listed below.
I have noticed a problem with my Lexus car since I purchased about 5 years ago. I could never reproduce the problem hence did not report to the dealer. Last weekend I came to know via newspapers and tv that some of the Lexus cars are having a problem related to engine stalling. My problem was exactly the same with the Lexus and I have notice more than 35/40 times but could not reproduce when I wanted. I felt at times that the engine stalling may be due to impurities in the gas but was not quite sure about it. I strongly feel that eventhough Lexus has not recalled my model, I have noticed engine stalling (while in motion) numerous times. At times, I have felt the condition to be unsafe. I have noticed engine stalling at lower speeds. If I remember correctly, I have not noticed such an occurrence while driving continuously at high speeds on highways.
