I have had the same issued since the date of purchase. From a stop when you accelerate the vehicle has a stall or hesitation for 2 or 3 seconds. This does not occur every time thus creates a problem for Lexus. I have complained to Lexus and gone through the hearing process which is a waste of time. The representatives from Lexus and the hearing panel drove the vehicle across the street from the hotel and around the Costco parking lot and said the vehicle did not demonstrate a problem. The vehicle has a problem!
Operating the vehicle above 25 miles per hour.
Lexus needs to own up to the fact that the vehicle has a problem and correct it!
