no warm air on passenger side all lower paddle motors working correctly then a 23h job to strip to the heater core only 4 reported cases worldwide that seems to be ok then it could only be the main motor thats never ever failed, lexus uk is sending technical guys to Edinburgh free of charge as this is a 50h job and unit has no part number as they never thought it would fail before end of cars life!!!

Potential repair cost of over £5000 or $7000+

Despite this fault the car is just awesome and so, so underated its scary averages 36mpg on cruise at 70mph.....42mpg at 60mph....imp gallons uk.

UPDATE; LEXUS UK now saying they wont look at it unless we authorise them to $9000 of work to nail down fault and even then they might still charge the entire amount looks like they are fully aware of this manufacturing design fault, despite having a full lexus service history! BUYER BEWARE our local dealer giving us full purchase refund other owners wont be so lucky!
