Hi I've just bought an 06 reg IS220 with 30k on the clock about 2 and a half months ago and brought it in to lexus for a service and requested them to check out the engine down power recall, intermediate service, power steering recall and rear brake caliper recall. They've reflashed the ECU, apparently cleaned the EGR (initially told me they were changing it because the private dealer who sold the car agreed to pay for it, but when I got the car back lexus told me they've only cleaned it), changed the air filter, did the oil service and the steering / brakes recall job, but when I got back my car it is just sluggish - with very bad turbo lag. The engine just wouldn't respond for 1 second or so, especially if the accelerator is floored and seemed to have a 'pull back' effect when 2nd is engaged even at 15mph or less (also other gears). This is especially evident when the engine is cold. Before sending the car in, the car drives smoothly without any 'pull back' effect after gear changes / when accelerating. It was also much more powerful with a less noisy engine.
I've brought it back for about 3 times for them to check it - Add coolant (not done even I've requested that before the service), steering pulling & downpower issue and they said it was because of the different tyre thread, and the power is because of turbo lag (saying that it's the same as their 09 reg new model). I've changed the tyre and brought it back again and they finally sorted the alignment and the car goes straight now (they just blamed the pot holes, whereas I think they've not done the tracking after changing the steering rack!)
I have booked in to ask them to check the power loss again end of this month - this time stating that it happens when it's cold. He said he will charge 1 hour labour & any addition if it's not a recurring problem, or they don't find any problem, so I am not sure whether to live with it or to bring it in to them again. Please advice.
Many thanks
