Hello,

I just joined this board and will appreciate your feedback on the following issue:

I am looking to buy a Lexus 2004 ES 330 with 4,000 miles from a dealership. This car was bought back from the owner that purchased it a few months ago. The owner was experiencing a hesitancy when accelerating and when coasting.

The dealership service department is telling me that is was computer system issue that has been fixed.

Their explanation is that these cars have now a computerized system that adjusts to the driving patterns/style/behavior of the driver. I believe it is called the Engine Control System.

After the owner experienced the acceleration hesitancy problem, he took it to the dealership to have it fixed. The dealership used the Lexus engineers latest software to upgrade the car's computerized system. However, the owner was still experiencing the same hesitancy issue and was not satisfied with the car. The dealership bought it back from the owner and the car is now for sale.

I spoke with the service department and they assured me that there is nothing to be concerned about. The car has no mechanical problems at all. The computerized system has been upgraded with the latest software provided by the Lexus engineers and that the car is fine now. Basically, he said it was an owner issue and not necesarily a car issue.

Any comments or advice on this type of issue that will help me make a decision whether to purchase this car or not will be very much appreciated. I don't want to make a risky purchase.

When you say "accelerate quickly", are you talking about wide open throttle, or just aggressive acceleration?

This could be an EGR valve problem, but it sounds more like an air/fuel mixture issue since it runs fine otherwise.

Have you checked the error codes to see if there are any stored?
