What Problems Does the 2008 Infiniti M35 Have?

The 2008 Infiniti M35, while generally considered a reliable vehicle, does have some reported issues that owners and prospective buyers should be aware of. One of the more commonly cited concerns revolves around the transmission. Some owners have reported premature failure or slipping issues, particularly in models that have accumulated higher mileage. This can manifest as rough shifting or a loss of power. Regular maintenance, including timely fluid changes, is crucial for mitigating this risk.

Another area of concern for some owners involves various electronic components. This can include issues with the infotainment system, such as glitches with the navigation or audio, or problems with the power windows and locks. While not as critical as mechanical failures, these can be frustrating and costly to repair.

The ABS (Anti-lock Braking System) and VDC (Vehicle Dynamic Control) warning lights illuminating on the dashboard are also reported. This often points to a failing wheel speed sensor or an issue with the ABS module itself. While the car will still brake, these systems are essential for safety, and their malfunction requires prompt attention.

Suspension components, such as ball joints and bushings, can also wear out over time, leading to clunking noises or a less composed ride. Given the sport-luxury nature of the M35, drivers often expect a certain level of refinement, so worn suspension parts can detract from the experience.

While there haven't been widespread, highly publicized recalls affecting the 2008 model year specifically that indicate systemic failure, it's always advisable to check for any outstanding recalls with the NHTSA database using the vehicle's VIN. As for long-term reliability, many M35 owners report good experiences when vehicles are properly maintained. The engine and drivetrain are generally robust, but the aforementioned transmission concerns highlight the importance of preventative maintenance and addressing any early warning signs. The overall reliability is considered good, but potential buyers should factor in the possibility of addressing some of these common issues, especially on higher-mileage examples.

How long will the 2008 Infiniti M35 last?

The 2008 Infiniti M35, with its robust V6 engine and generally well-built chassis, has the potential for long-term durability. Owners who diligently follow the recommended maintenance schedule, including regular oil changes, transmission fluid flushes, and timely replacement of wear items, can expect to keep their M35 on the road for well over 150,000 miles, with many reaching 200,000 miles or more. The powertrain is a strong point for long-term service. However, weaknesses that can emerge over time include potential transmission issues (as mentioned previously) and the aging of electronic components. Suspension parts will also eventually require attention. With consistent care and proactive addressing of minor issues, the M35 can offer many years of reliable service, but neglecting maintenance, especially concerning the transmission and fluids, can significantly shorten its lifespan.

What Technology & Safety Features are Included?

The 2008 Infiniti M35 offered a respectable array of technology and safety features for its era, aiming to provide a luxurious and secure driving experience. Standard technology included a premium Bose audio system, often with a 6-disc CD changer, and an Infiniti Intelligent Key with push-button ignition, which allowed for keyless entry and starting. A Bluetooth hands-free phone system was also standard, enhancing connectivity. Many models came equipped with a rearview camera, a valuable safety feature even then, aiding in parking and maneuvering.

Optional technology and convenience features were plentiful and elevated the M35's luxury quotient. These often included an advanced navigation system with a touch-screen interface and voice recognition, which was quite sophisticated for the time. Other popular optional upgrades were climate-controlled front seats (offering both heating and cooling), and premium interior materials. The optional Sport Package not only enhanced performance but sometimes included upgraded interior trim.

Driver-assistance features were also available, most notably the Intelligent Cruise Control (ICC), which could maintain a set distance from the vehicle ahead. While not as advanced as today's adaptive cruise control systems, it was a significant convenience on longer journeys. Some models could also be equipped with an advanced climate control system featuring an air purifier.

In terms of safety, the 2008 M35 came standard with front-seat side-impact airbags and roof-mounted curtain side-impact airbags for front and rear occupants. It also featured standard stability and traction control systems (VDC) to help prevent skids. The chassis was designed with crumple zones to absorb impact energy.

Crash-test ratings from the National Highway Traffic Safety Administration (NHTSA) for the 2008 Infiniti M35 were generally good. It received 5-star ratings in frontal driver and passenger crash tests, and 5-star ratings in side-impact driver and rear passenger crash tests. The Insurance Institute for Highway Safety (IIHS) also awarded it top marks, rating it as a "Top Safety Pick", achieving good ratings in front-impact and side-impact tests.

2008 Infiniti M35 Prices and Market Value

When new, the 2008 Infiniti M35 had an original MSRP that typically ranged from around $41,000 to $50,000, depending on the trim level (M35 vs. M35x) and optional packages. As with most luxury vehicles, the M35 experienced significant depreciation in its first few years. Currently, on the used market, you can find 2008 Infiniti M35 models for a considerably lower price, generally ranging from $5,000 to $10,000, with prices highly dependent on mileage, condition, and the presence of desirable options. Factors affecting resale value include the vehicle's maintenance history (a well-documented service record significantly boosts value), overall condition (cosmetic and mechanical), mileage (lower mileage is always better), and trim level or packages equipped. Models with the Technology or Sport packages tend to hold their value slightly better due to their added desirability. The M35 has depreciated substantially, making it a potentially good value for used car buyers looking for luxury and performance at a more affordable price point.

2008 Infiniti M35 Cost of Ownership

Owning a 2008 Infiniti M35 can be considered moderately costly, especially when compared to mainstream sedans. Insurance costs can be higher due to its luxury status and performance, varying based on driver profile and location. Fuel costs are also a factor, as the 3.5L V6 is not the most fuel-efficient, averaging around 16-17 mpg combined. Maintenance will be on par with other luxury vehicles; expect to pay more for parts and labor at dealerships or specialized shops compared to non-luxury brands. Repairs, particularly for transmission issues or complex electronics, can be expensive. Overall, the M35 is not an economical car to own long-term, but its pricing on the used market can offset some of these ongoing expenses, offering a compelling value proposition for those seeking luxury features at a reduced cost.

2008 Infiniti M35 Insurance

Insurance for a 2008 Infiniti M35 is moderately priced, reflecting its status as a Sedan with strong safety ratings and
reasonable repair costs.

How Does the 2008 Infiniti M35 Compare to Other Sedan?

The 2008 Infiniti M35 competed in the mid-size luxury sedan segment against strong contenders like the Lexus GS 350, BMW 5 Series (e.g., 530i/525i), and Mercedes-Benz E-Class (e.g., E350).

Performance: The M35's 3.5L V6 offered robust acceleration and a sporty feel, often matching or exceeding the performance of base V6 rivals from BMW and Mercedes. The Lexus GS 350 also provided strong V6 performance. The M35's rear-wheel-drive bias contributed to its engaging driving dynamics.

Features: Infiniti consistently equipped the M35 with a generous list of standard luxury and technology features, often surpassing what German rivals offered at a similar price point. Features like the Bose audio, rearview camera, and push-button start were often standard on the M35, whereas they might have been optional on competitors. Lexus also offered a well-equipped cabin.

Reliability: The Infiniti M35 generally holds a good reputation for reliability, particularly its V6 engine. However, the 2008 model year has some reported transmission and electronic issues that can be more prevalent than in some Lexus models, which are renowned for their bulletproof reliability. BMW and Mercedes-Benz, while offering refined driving experiences, can be more expensive to maintain and repair long-term.

Price: The M35 typically offered a more aggressive price point when new and continues to offer a strong value proposition on the used market compared to its German counterparts and often the Lexus GS. Buyers could get more features for their money with the M35.

Alternatives:
  • Similar: Lexus GS 350 (2007-2009): Offers arguably superior reliability and a quieter, more refined ride. Performance is comparable.
  • Similar: Acura RL (2005-2008): Features standard SH-AWD, a sophisticated all-wheel-drive system, and a comfortable cabin, though its styling is more understated.
  • Higher Budget/Different Focus: BMW 5 Series (E60 generation): Provides a more driver-focused experience with sharper handling and a wider range of engine options, but typically at a higher cost for purchase and maintenance.
  • Higher Budget/Different Focus: Mercedes-Benz E-Class (W211 generation): Offers a more luxurious and comfortable ride, but often at a higher price and with potentially higher repair costs.
Overall, the 2008 Infiniti M35 remains a compelling choice for those seeking a blend of sportiness, luxury, and value, especially when compared to the premium pricing and potential long-term maintenance costs of its European rivals.

Final Verdict: Is the 2008 Infiniti M35 a Good Sedan?

The 2008 Infiniti M35 is ideal for buyers seeking a sporty and luxurious sedan that offers a compelling blend of performance and features without the premium price tag of its European competitors. It's particularly well-suited for those who appreciate a strong V6 engine and a comfortable, well-appointed interior. Given its age, buying new is not applicable; the M35 is strictly a used car purchase.

It is definitely worth buying if found in good condition with a solid maintenance history, especially for its current used market price, which offers excellent value. Buyers should prioritize well-maintained examples and ideally consider the M35x trim if all-wheel-drive is a necessity. Prospective owners should be prepared for potentially higher fuel and maintenance costs than a non-luxury vehicle, and factor in the possibility of addressing common issues like transmission or electronic glitches, particularly on higher-mileage units. A pre-purchase inspection is highly recommended.
