What to Know Before Buying a 2008 Infiniti EX35 SUV

If you're searching for a used 2008 Infiniti EX35, you're likely weighing its value as an affordable entry into the luxury compact SUV segment. This model, built on the same platform as the sporty G35 sedan, combines responsive handling, a powerful V6 engine, and a well-appointed interior—all at a fraction of today’s new car prices. However, while it offers strong driving dynamics and a premium feel, potential buyers must be aware of aging components, maintenance costs, and long-term ownership considerations. In this comprehensive guide, we’ll break down everything you need to know—from engine durability and transmission behavior to trim differences and common failure points—so you can make an informed decision when considering a 2008 Infiniti EX35 for sale.

Overview of the 2008 Infiniti EX35

The 2008 Infiniti EX35 marked the debut year of Infiniti’s first compact luxury crossover SUV. Positioned between the larger FX series and the midsize M sedans, the EX35 was designed to blend sporty performance with everyday usability. It shared its chassis and powertrain with the acclaimed G35 coupe and sedan, giving it a rear-wheel-drive bias (with optional all-wheel drive) and a driving experience that stood out in a market dominated by softer, front-wheel-drive-based competitors.

Available in two trims—Base and Journey—the EX35 offered increasing levels of comfort and technology. The Journey package added features like leather upholstery, adaptive headlights, navigation, and a Bose audio system, making it a compelling option for those seeking a more complete luxury experience 1.

Engine and Performance: The Heart of the EX35

⚙️ At the core of the 2008 Infiniti EX35 is Nissan’s legendary VQ35DE 3.5-liter V6 engine. Producing 297 horsepower and 253 lb-ft of torque, this engine delivers smooth, linear power and enthusiastic acceleration. Paired exclusively with a 5-speed automatic transmission, the drivetrain provides a balance of responsiveness and refinement that still holds up well against modern six- and eight-speed units.

While not the most fuel-efficient vehicle in its class—averaging around 17 mpg city and 24 mpg highway—the EX35 prioritizes driving engagement over economy. Its RWD-biased architecture enhances cornering stability, especially in AWD models, which use an intelligent system that normally sends power to the rear wheels but shifts torque forward when slippage is detected.

⚡ Enthusiasts often praise the EX35 for its sporty feel, noting that it handles more like a lifted sports sedan than a traditional SUV. This makes it ideal for drivers who want versatility without sacrificing driving excitement.

Trim Levels: Base vs. Journey

🛒 When shopping for a used 2008 Infiniti EX35, understanding the difference between trims is crucial. The two available configurations offer distinct feature sets:

• Base Trim: Includes standard amenities such as dual-zone climate control, power-adjustable front seats, a sunroof, and a six-speaker audio system. Rear-wheel drive is standard; all-wheel drive is optional.
• Journey Package: Adds significant upgrades including leather-trimmed seating, wood interior accents, heated front seats, a memory driver’s seat, adaptive bi-xenon headlights, and an in-dash navigation system with real-time traffic.

✨ The Journey trim significantly increases both comfort and resale appeal. However, due to the complexity of systems like navigation and adaptive lighting, these models may require more maintenance or repairs over time—especially if previous owners didn’t keep up with software updates or bulb replacements.

Reliability: Is the 2008 Infiniti EX35 Dependable?

🔧 One of the most frequently asked questions about the 2008 Infiniti EX35 is: Is it reliable? Overall, the answer is cautiously positive. The VQ engine is widely regarded as one of the most durable mass-produced V6 engines ever made. With proper maintenance, many examples exceed 150,000 miles without major mechanical failures.

However, several known issues should be checked during any pre-purchase inspection:

• VVT (Variable Valve Timing) Solenoids: These can fail over time, leading to rough idling, poor fuel economy, or check engine lights. Replacement is relatively straightforward but necessary if symptoms appear.
• Transmission Mounts: Worn mounts are common in higher-mileage vehicles and can cause shuddering during acceleration or gear changes.
• Brake Booster Check Valve: Some owners report a hissing noise from the brake pedal area, often traced to a failing check valve in the vacuum system.
• Infotainment System: Older navigation units may suffer from slow response times, screen flickering, or GPS signal loss.

✅ Pro Tip: Always request service records and consider a PPI (Pre-Purchase Inspection) by a qualified mechanic familiar with Infiniti/Nissan platforms. Pay special attention to fluid condition, suspension components, and electronic systems.

Maintenance Costs and Ownership Experience

📍 While initial purchase prices for the 2008 EX35 are attractive—often ranging from $3,000 to $8,000 depending on mileage and condition—ongoing maintenance should not be overlooked. As a luxury vehicle, parts and labor costs are typically higher than mainstream SUVs.

Common scheduled services include:

• Oil changes every 5,000–7,500 miles using synthetic oil
• Transmission fluid flush every 60,000 miles
• Timing chain inspection (though generally robust, tensioners can wear)
• Coolant system flush every 60,000 miles
• Brake pad replacement every 40,000–60,000 miles

🧰 Independent specialists often provide lower-cost alternatives to dealership labor rates, especially for routine maintenance. OEM or high-quality aftermarket parts are recommended to maintain reliability.

Resale Value and Market Trends

📈 According to recent data from automotive marketplaces, the average price for a used 2008 Infiniti EX35 has increased slightly over the past year, reflecting growing interest in older premium vehicles with proven powertrains 2. Well-maintained examples with under 100,000 miles and full service history command premiums, particularly those equipped with the Journey package and AWD.

🚗 Despite being over 15 years old, the EX35 retains a niche following among enthusiasts who appreciate its balanced ride, engaging dynamics, and understated styling. Unlike flashier German rivals, the EX35 avoids excessive depreciation stigma, making it a smart buy for budget-conscious luxury seekers.

How Long Can a 2008 Infiniti EX35 Last?

⏳ With consistent maintenance, a 2008 Infiniti EX35 can reliably reach 150,000 to 200,000 miles. There are verified reports of some units surpassing 250,000 miles with only routine repairs. Key longevity factors include:

• Regular oil changes with high-quality synthetic lubricants
• Proper cooling system maintenance to prevent overheating
• Timely replacement of drive belts and hoses
• Avoiding short-trip driving cycles that don’t allow the engine to fully warm up

❗ Note: Neglecting maintenance—especially coolant exchanges and transmission servicing—is the leading cause of premature failure in otherwise robust components.

Common Misconceptions About the EX35

🔍 Several myths persist about the 2008 Infiniti EX35. Let’s clarify them:

• Myth: It’s just a rebadged Nissan Murano. False. While both are crossovers, the EX35 uses the FM platform from the G35, offering RWD bias and superior handling compared to the FWD-based Murano.
• Myth: The interior space is cramped. Partially true. The sloping roofline reduces headroom in the rear, making it less suitable for tall adults on long trips. But cargo volume (15.3 cu ft behind rear seats) is competitive for its class.
• Myth: Parts are impossible to find. Incorrect. Due to Nissan’s global parts network and third-party suppliers, most mechanical and electrical components remain available.

What Replaced the Infiniti EX35?

🏭 After 2013, Infiniti discontinued the EX35 and replaced it with the QX50, aligning with the brand’s new naming convention. The second-generation QX50 (2018–present) evolved into a more conventional luxury SUV, eventually switching to a variable-compression turbocharged four-cylinder engine.

🌐 While newer QX50 models offer improved fuel efficiency and advanced safety tech, many purists argue that the original EX35 delivered a more engaging driving experience thanks to its naturally aspirated V6 and sport-tuned suspension.

Tips for Buying a Used 2008 Infiniti EX35

📌 Here’s a practical checklist to follow when evaluating a potential purchase:

1. Verify Vehicle History: Use a CARFAX or AutoCheck report to confirm accident-free status and ownership patterns.
2. Inspect for Rust: Check wheel wells, undercarriage, and door jambs—especially in regions with heavy winter road salting.
3. Test All Electronics: Operate windows, sunroof, climate controls, navigation, and backup camera to ensure functionality.
4. Listen for Noises: Pay attention to ticking (possible VVT issue), whining (differential or transmission), or groaning (suspension bushings).
5. Check Tire Wear: Uneven wear may indicate alignment problems or worn control arms.
6. Review Maintenance Records: Look for evidence of timing chain inspections, transmission flushes, and coolant replacements.

🔎 Consider hiring a certified technician for a thorough diagnostic scan. OBD-II tools can detect pending codes not yet triggering the check engine light.

Final Thoughts: Who Should Buy a 2008 Infiniti EX35?

👥 The 2008 Infiniti EX35 is best suited for:

• Budget-focused buyers wanting luxury features without new-car pricing
• Driving enthusiasts seeking a sport-oriented compact SUV
• Shoppers in mild climates where rust isn’t a major concern
