I've just joined the "AHC leakage club". Yesterday i drove out of my +25c heated parking to a -25c day and instantly fluid leaked out from the passenger rear (where the fill tank is) and all of the fluid seems to be gone, vehicle stuck in low mode. When I phoned Lexus, not only can they not even look at it til dec 17, byt they said it will be a minimum 12 hoursof labour not including parts if ther is an AHC leakage. From people's experience on here, if it leaks under the fill tank, is it the lines or something else? I pulled the cover off and the lines that I could actually see looked dry. Thoughts? i am in Calgary so the Toronto mechanic can't help me
