Leak under car can not see were it is coming from as the placstic cover has 88 k on the clock and its book in for 90 k service any help would be good thinking oil leak rear main

changed the oil and then the loosing power started. I reset the car by unhooking the battery. The car ran fine for a day and it started loosing poer again

I purchased a certified used 08 ISF. It only had 26k miles. I have driven 10k miles in four months. Should I need to be replacing the rotors? Seems like very short mileage (35k) to have to be replacing rotors.

have read on a lexus forum where several people have had there water pumps replaced under warranty due to leaking. replacing with a redesigned pump. any documented info? thanks.
