I would call lexus and see if they will goodwill it as it is a known problem and see if your dealer will go to bat for you.

Brake fluid is hydrophilic and absorbs water and for abs systems, many manufactureres recommend either time or mileage interval or both for replacing the fluid. The moisture in the fluid can damage the abs system over time. For example, I beleive my honda recommends changing brake fluid once very 3 years. Also with brake fluid, the fluid needs be removed via the bleeder on the caliper as the fluid does not really ciruclate so just replacing the fluid in the reservoir in not as effective as a full flush through the bleeders. Some cars may also require activation of the abs system to make sure the abs unit is flushed as well. Power steering is different in that some cars do not use hydraulic fluid and some do. If the car uses hydraulic fluid you may want to change it as it will absorb moisture and at some point corrode metal lines and what not. Many manufacturers do not mention power steering fluid as a maintenance item. Power steering fluid does circulate so using the turkey baster method works quite effectively.

I think i was misunderstood, when i said you do not have to change plugs or oil when you use it. Rather unlike some combustion and injector cleaners- like seafoam- you do not have to immediately change the oil or the plugs after using it. You have to change your oil regularly and use good quality stuff and change your plugs at the recommended intervals and do all the maintenance. I have tried all kinds of additives and i have fouond that techron is some of the bust stuff out there. I have used it as preventative maintenance, none of the cars i have owned ever had a fuel related or emissions related problem. I routinely drive my cars well over 190k before getting rid of them. I do most of the work on my cars myself. I even put a moly additive in my engine, but i am sure someone will question that as well. I also live in a state where they actually check emissions.

Chevron Techron is some of the best stuff out there. Did a lot of research and it is one of the best formulations without being the harshest. You do not have to change plugs or oil when you use it. I put it in every oil change.
