2023 Lexus Rx450h problems

Common 2023 Lexus Rx450h problems

The Lexus RX 450h, a hybrid luxury crossover SUV, is known for its low emissions and excellent fuel economy, making it a popular choice for eco-conscious buyers. However, like any vehicle, it is not without its common problems.

One of the most frequently reported issues with the RX 450h is the battery going flat after two to three weeks of not being used. This is especially inconvenient in a hybrid car because the battery can’t be jump-started. Instead, it has to be trickle charged, which usually means calling out a breakdown service. This problem is due to the fact that the RX 450h is a heavy car, which puts a lot of pressure on the suspension, particularly the shock absorbers. This can cause the vehicle to dip at one side and the ride to feel less smooth than it once did. Worn shock absorbers need to be replaced, and any loose parts should be tightened if there is a leak in the air suspension system.

Another common problem with the RX 450h is the actuator, a hydraulic component that communicates with the ECU to take control of the brakes in an emergency situation. RX 450h models have unreliable anti-lock braking systems, and the actuator is often to blame. The actuator needs to be replaced for the system to function correctly.

Non-engine electrics, such as the media system and windows, may also become faulty. Many 450h drivers have complained about problems like this, but Lexus has never issued a recall. The specific repair required will depend on which part of the electrical system has gone wrong. An auto electrician can identify the problem and advise on the appropriate solution.

The first generation of the RX 450h hasn’t been subject to any recalls from Lexus, showing its reliability. However, the second generation of the 450h, which came out in 2016, has been known to have problems with the fuel pump impeller cracking, which can cause the engine to stall or fail to start.

In summary, the Lexus RX 450h is a reliable and efficient hybrid SUV, but like any vehicle, it is not without its common problems. These include the battery going flat, issues with the actuator and anti-lock braking system, faults with non-engine electrics, and problems with the fuel pump in later models.
