What Problems Does the 2008 Lexus RX 400h Have?
The 2008 Lexus RX 400h generally upholds Lexus's reputation for reliability, but like any complex hybrid system, it has specific long-term considerations. The most frequently reported potential problem involves the hybrid battery pack. As these vehicles age, the nickel-metal hydride (NiMH) battery can degrade, leading to reduced fuel economy or, eventually, failure. Replacement can be very costly, often thousands of dollars, though reconditioned or third-party options exist. It's crucial for potential buyers of high-mileage examples to inquire about battery health or replacement history.
Another area of concern can be the inverter/converter assembly, which manages power flow between the battery, motors, and gasoline engine. While less common than battery issues, a failing inverter can also be an expensive repair. Some owners have reported issues with the regenerative braking system's feel, which can be less linear than conventional brakes, but this is more of a characteristic than a "problem."
For the 2008 model specifically, there were no major widespread, unique issues reported compared to its earlier model years within the same generation. However, general wear items such as struts, bushings, and control arms may require attention on high-mileage units, typical for any vehicle.
Recalls for the 2008 Lexus RX 400h included issues related to:

Recalls for the 2008 Lexus RX 400h included issues related to:
- A potential accelerator pedal entrapment (part of a larger Toyota/Lexus recall campaign, though less prevalent on RX models).
- Issues with the electric power steering system possibly losing power assist (though this was more prominent on certain other Toyota/Lexus models).
- A few minor recalls concerning brake lamp switches or seat heater wiring in earlier RX models, but the 2008 model year generally has a clean record for significant, unique recalls affecting its core hybrid components at the time. Always check the specific VIN for the latest recall information.
How long will the 2008 Lexus RX 400h last?
Based on owner data and typical Lexus maintenance habits, a well-maintained 2008 Lexus RX 400h can reliably achieve 200,000 to 250,000 miles or more, often providing 15-20 years of service. Its long-term durability is exceptional for the gasoline engine and drivetrain components, mirroring Lexus's reputation. However, the Achilles' heel for extended longevity and affordability often lies with the hybrid battery pack. While many original batteries last beyond 150,000 miles, their eventual degradation is inevitable and replacement costs can impact overall ownership value. Consistent maintenance, including regular fluid changes and prompt attention to warning lights, is crucial for maximizing its lifespan. Aside from the hybrid battery, the RX 400h remains a highly durable and long-lasting vehicle.

- For Practical & Reliable SUV: A Toyota Highlander (non-hybrid) offers much of the RX's practicality and reliability in a less luxurious, but equally dependable, package.
Final Verdict: Is the 2008 Lexus RX 400h a Good Sport Utility Vehicle?
The 2008 Lexus RX 400h is an ideal vehicle for someone seeking a comfortable, quiet, and refined luxury SUV with excellent fuel efficiency for its class and year. It's perfect for buyers who prioritize Lexus's renowned reliability and a smooth, effortless driving experience.
It is definitely worth buying if you can find a well-maintained example with a documented service history, especially one where the hybrid battery has been recently replaced or certified as healthy.
