The Good
The RX 400h boasts smooth, potent acceleration thanks to its hybrid powertrain, offering V8-like performance with four-cylinder economy. Its legendary Lexus reliability, plush ride, and quiet, upscale cabin appeal to practical buyers seeking longevity and comfort. The sleek, understated design and eco-friendly aspect provide emotional appeal, making it a valuable, efficient, and refined choice.
The Bad
Potential weaknesses include aging hybrid battery packs, which can be costly to replace. The regenerative braking system can feel inconsistent. Some owners report higher-than-average road noise compared to newer luxury SUVs. Its older infotainment system also lacks modern connectivity features. The premium for hybrid components can lead to higher specialized repair costs.

Analysis
What Problems Does the 2008 Lexus RX 400h Have?
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:
- 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.

2008 Lexus RX 400h Prices and Market Value
Today, in the used market, current prices for a 2008 RX 400h vary significantly based on mileage, condition, and maintenance history, particularly the state of the hybrid battery. You can generally expect to find models ranging from $6,000 for high-mileage or fair-condition examples to $12,000 or even $15,000 for well-maintained, lower-mileage units with documented service.
Depreciation for the RX 400h has followed a typical luxury vehicle curve, with the initial significant drop in the first few years. However, its strong reliability and hybrid efficiency helped it retain value better than some conventional luxury SUVs. The primary factor affecting its current resale value is the potential cost of hybrid battery replacement, which can deter buyers and significantly impact its price. A recently replaced or certified battery can boost its value considerably.

How Does the 2008 Lexus RX 400h Compare to Other Sport Utility Vehicle?
Compared to Rivals:
- Performance: The RX 400h's 268 hp combined output gave it V8-like acceleration (0-60 in 7.3s), often outperforming or matching V6-powered rivals like the Acura MDX (2008: 3.7L V6, 300hp, 0-60 in ~6.5s) or BMW X5 (2008 3.0si: 260hp, 0-60 in ~7.5s; 4.8i: 350hp, 0-60 in ~6.0s). While the MDX offered a sportier drive, the RX 400h excelled in smooth, quiet power delivery.
- Features: It matched rivals like the Mercedes-Benz ML-Class or BMW X5 in luxury appointments (leather, premium audio, navigation) but offered less dynamic handling than the Germans. The Acura MDX of that era was also well-equipped with tech and a more engaging drive.
- Reliability: The RX 400h's gasoline engine and traditional Lexus components are exceptionally reliable, often surpassing German rivals. However, the unique hybrid system components introduce specific long-term reliability considerations (hybrid battery, inverter) that conventional SUVs don't share. The Acura MDX of that era also enjoyed strong reliability ratings.
- Price (New): It was competitively priced with entry-level luxury SUVs from German brands and similar to the Acura MDX.
Recommended Alternatives:
- For Hybrid Efficiency & Reliability (Newer): A newer Lexus RX 400h/450h (3rd or 4th Gen) or Toyota Highlander Hybrid offers updated tech and potentially healthier hybrid components.
- For Sportier Driving & Reliability: A 2008-2013 Acura MDX is a strong alternative, offering a more athletic driving experience, comfortable interior, and excellent reliability without the hybrid system complexities.
- For Pure Luxury & Performance (Non-Hybrid): A V8-equipped BMW X5 or Mercedes-Benz ML-Class provides higher performance and luxury but at a significant fuel economy penalty and potentially higher maintenance costs as they age.
- 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?
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. Buyers should be prepared for the potential long-term cost of hybrid battery replacement, which is the main caveat for older hybrid vehicles.
Buying a used RX 400h (as new is not an option) is best for those who appreciate value, a quiet cabin, and better-than-average fuel economy. It suits suburban families or commuters who want a touch of luxury without the typical gas station frequency. Avoid examples with unknown hybrid system health unless you budget for potential battery replacement.
