The Lexus RX400h, like any vehicle, has experienced some common problems reported by owners. Here are some of the common issues that have been reported:
1. Inverter Leaks: The inverter, an important part of the hybrid engine, has been known to leak coolant. Signs of a leaking inverter include lower liquid levels in the inverter coolant reservoir and a crusty pink substance around the inverter.

Some owners have claimed that they need to press extra hard on the brake pedal to fully engage the brakes, or that the braking system does not work properly. If the vehicle is still under warranty, the issue can be resolved by taking it to a dealer for a software upgrade.
3. Transmission Leak: The 2005-2008 Lexus RX400h had a common problem with a transmission leak. This was caused by a faulty transmission cooler hose that would leak transmission fluid. The manufacturer addressed this issue with a revised transmission cooler hose.
