Summary Verdict

The 2011 Land Rover LR4 is a highly capable vehicle, but potential buyers and owners should be aware of specific reliability concerns. The 5.0L V8 engine can be susceptible to timing chain and cooling system issues, while the sophisticated air suspension system may develop leaks or compressor problems. Transmission issues, particularly with the mechatronic unit and torque converter, are also noted. Electrical gremlins, such as battery drain and infotainment glitches, can occur. Less common but notable are interior water leaks from clogged sunroof drains and HVAC blend door actuator failures. Addressing these potential issues proactively can help maintain the LR4’s performance and longevity.
