What Problems Does the 2008 Lexus GS 450h Have?
The 2008 Lexus GS 450h is generally known for its strong reliability, a hallmark of the Lexus brand. However, like any vehicle, it has a few common concerns that owners and prospective buyers should be aware of. The most significant potential issue revolves around the hybrid battery system. While these batteries are designed to last a considerable time, replacement can be a substantial cost, often ranging from $2,000 to $5,000 or more, depending on the repair facility and the specific battery. Symptoms of a failing hybrid battery can include reduced performance, warning lights, and decreased fuel efficiency.
Another frequently reported issue, though less common, is with the water pump. Leaks from the water pump can lead to coolant loss and potential engine overheating if not addressed promptly. Regular inspection of the cooling system is advisable. Some owners have also reported minor electronic glitches, such as issues with the infotainment system or power accessories, which are often fixable with software updates or minor repairs.
The exhaust system, particularly the catalytic converters, can be prone to corrosion and eventual failure over time, especially in regions with harsh winter climates and heavy road salt usage. While there haven't been widespread, model-year specific recalls that are particularly alarming for the 2008 GS 450h, it's always prudent to check for any outstanding recalls with the NHTSA. For the most part, the mechanical components of the gasoline engine and transmission are robust. The long-term reliability is heavily dependent on consistent maintenance, especially fluid changes and proper care of the hybrid system.

How long will the 2008 Lexus GS 450h last?
With proper and consistent maintenance, the 2008 Lexus GS 450h is capable of lasting well over 200,000 miles, and many owners report achieving 250,000 miles or more. The core V6 engine and the hybrid components are built for longevity. Weaknesses that typically emerge over time are related to wear-and-tear items such as suspension components, brake pads, and tires, which are standard for any vehicle. The most significant long-term concern remains the eventual need for hybrid battery replacement, which often occurs between 150,000 to 200,000 miles, or roughly 10-15 years of service, though this can vary significantly with driving habits and climate. Regular fluid changes and timely attention to any warning signs are crucial for maximizing its service life.
What Technology & Safety Features are Included?
The 2008 Lexus GS 450h offered a sophisticated suite of technology and safety features for its era, blending luxury with convenience. Standard technology included a premium audio system, often with a 6-disc CD changer and auxiliary audio jack, alongside a voice-activated navigation system with a backup camera. Bluetooth hands-free phone connectivity was also integrated. The interior featured dual-zone automatic climate control and a power tilt-and-telescopic steering wheel with memory functions.
Driver-assistance features, while not as extensive as modern vehicles, included features like rain-sensing windshield wipers and an auto-dimming rearview mirror with a compass. Optional advanced features could enhance safety and convenience significantly. These often included adaptive cruise control, which could automatically adjust the vehicle's speed to maintain a set distance from the vehicle ahead, and a pre-collision system that could help prepare the brakes and seatbelts if a crash was imminent.
Safety was a priority, with standard front and side-impact airbags for the front occupants, as well as side curtain airbags for both rows. Anti-lock brakes (ABS), electronic brakeforce distribution (EBD), and brake assist were also standard. Vehicle stability control (VSC) and traction control (TRAC) helped manage slippery conditions.
In terms of crash-test ratings, the 2008 Lexus GS models generally performed very well. The National Highway Traffic Safety Administration (NHTSA) awarded the 2008 Lexus GS 450h (and its non-hybrid counterparts) top marks, including 5-star ratings in frontal and side-impact crash tests for the driver and front passenger, and 4-star ratings in rear side-impact tests. The Insurance Institute for Highway Safety (IIHS) also rated the GS models as "Good" in their frontal offset and side-impact crash tests, designating it a Top Safety Pick for its model year.

- 2008 Infiniti M35/M45: The Infiniti M series offered strong performance (especially the M45 with its V8) and a luxurious cabin, often at a slightly lower price point than the Lexus. Reliability is generally good, though perhaps not quite at Lexus levels.
- 2008 BMW 5 Series (535i/550i): If driving dynamics and sportiness are paramount, the BMW 5 Series is hard to beat. However, it typically comes with higher maintenance costs and potentially lower long-term reliability compared to the Lexus.
Final Verdict: Is the 2008 Lexus GS 450h a Good Sedan?
The 2008 Lexus GS 450h is ideal for the discerning buyer who seeks a sophisticated luxury sedan that offers potent performance without sacrificing fuel efficiency. It's particularly well-suited for individuals who value Lexus's reputation for reliability, comfort, and a refined driving experience, but also want an eco-friendlier option that still packs a punch.
