During inspection, technician noted coolant reservoir very low. Technician traced coolant leak to valley seal. Recommend to replace noticed before performing coolant replacement found the reservoir was near empty indicating a leak in the system. Inspected radiator assembly and found no obvious leaks. Inspected coolant valley from under the car and found large amounts of dry coolant around the transmission bell housing. This confirms the coolant valley is indeed leaking and will need to be resealed. Reseal coolant valley and replace seals/gaskets necessary. Driver comment: this is a known issue with toyota/lexus v8 engines. Toyota/lexus needs to take ownership (recall) and fix the worn out seals without charge.

What 2012 Lexus GX owners say
Most recent owner complaints, unedited.
Takata recall. Unacceptable wait time for remedy (replacement.) in our present home state of florida, another(!!) floridian has died -- this time, a 34yr old woman, 07.28.2017. During the mandatory hurricane evacuation, our family was forced to use our front passenger seat. Thank g-d nothing happened, but this corrective period is gone on too long. We have been waiting months for resolution -- and all we are told is that the necessary part is unavailable and to wait longer -- and in the interim place our family in a potentially deadly situation. What is it going to take to get the replacement air bag?! Does someone's teenage child have to die during a mandatory evacuation in order for resolution to happen?! I am tired of being patient. Please, someone explain the lack of apparent urgency. How many more people need to die? The death toll estimate is now 19. How many more people need to die before the rest of us get answers?!?!
A buzzy/ squeeze noise heard when apply brake pedal elec. Stability control is hard to use propulsion makes up a large noise when start engine.
