★ Top Answer
Three frequent issues frequently arise with the 2007 Lexus RX400h. The initial problem involves the use of rubber for the oil cooler lines on the vehicle, which can rupture and result in oil leaks or a complete loss of oil pressure, depending on the severity of the break. Additionally, the engine's VVTi lines are also made of rubber and can deteriorate, causing incorrect valve timing and rough engine performance. Lastly, a common concern relates to the hybrid battery pack, which has been reported to fail before reaching 100,000 miles in certain vehicles. Replacing this component can be quite costly.
