On the 2010-2019 Lexus RX, the water pump on the RX fails prematurely due to internal seal and bearing wear. Coolant weeps from the pump weep hole and the bearing develops play, causing a whining or grinding noise from the front of the engine. Failure rates are highest between 60,000-100,000 miles.
Replace the water pump and thermostat assembly. Use OEM Aisin or Denso parts for reliability. Replace the drive belt and tensioner at the same time. Flush the cooling system with new Toyota Super Long Life Coolant during the repair.

On the 2010-2017 Lexus RX, the AC evaporator core in the RX develops pinhole leaks from internal corrosion, causing slow refrigerant loss. The system gradually loses cooling capacity over weeks or months as the charge leaks through the evaporator. This is an expensive repair because the entire dashboard must be removed to access the evaporator.
Replace the AC evaporator core and receiver/drier. This requires full dashboard removal, which is 8-12 hours of labor. Recharge the system with the correct amount of R-134a refrigerant. Replacing the expansion valve at the same time is recommended while the dash is apart.

On the 2007-2017 Lexus RX, the 3.5L 2GR-FE V6 in the RX350 consumes excessive oil, often requiring a quart every 1,500-3,000 miles. The piston ring design allows oil to bypass into the combustion chamber, and the PCV system contributes to the problem. Toyota acknowledged the issue with a TSB covering piston ring replacement.
Dealer oil consumption test to document the rate. If excessive, piston ring replacement is the definitive fix under Toyota TSB. Check and clean the PCV valve as a first step. Monitor oil level weekly and keep a log of consumption for warranty claims.
