Problem overview

Some Lexus RX450h owners report experiencing rear strut failure, which can lead to leaking struts and subsequent tire cupping issues due to a compromised suspension system. These leaking struts often indicate fluid leaks, a common sign of suspension problems. Owners may notice tire cupping, or scalloped tires, resulting from irregular wear patterns caused by failing struts. Additionally, if the vehicle "nosedives" forward during braking, this may signal strut or shock failure, further contributing to tire wear issues. Greasy or oily shocks are also clear indicators of fluid leaks that can negatively affect suspension performance and handling. It is crucial for owners to address these issues promptly to prevent further damage to the suspension system and ensure vehicle safety on the road.
