Vehicle History Report

What Problems Does the 2011 Infiniti M37 Have?

The 2011 Infiniti M37 generally enjoys a reputation for solid reliability, but like any vehicle, it has some frequently reported issues and long-term concerns to be aware of. One common complaint revolves around the brakes, specifically the original equipment pads which tend to produce excessive brake dust. Some owners also report premature rotor wear or warping, especially under spirited driving conditions. While not as widespread as in some other Nissan engines, the VQ37VHR engine in the M37 can, in some instances, exhibit increased oil consumption, particularly at higher mileages. Regular oil level checks are therefore advisable.

As the vehicle ages, wear on suspension components is also a common report. Owners might experience noise, such as clunks or squeaks, or a noticeable degradation in ride quality due to worn bushings (e.g., lower control arm bushings) or aging struts. Minor infotainment or electrical glitches, such as navigation system quirks or Bluetooth connectivity issues, have also been reported, though these are typically less severe.

In terms of recalls, the 2011 Infiniti M37 has a few notable ones:

• Rearview Camera Display Issue (NHTSA Campaign 18V210000): Affecting 2011-2012 M37 and M56 models, this recall addressed a condition where the rearview camera display might not activate if the driver shifted into reverse too quickly after starting the ignition. A software update was provided to rectify this.
• Incorrect Tire Pressure Information (NHTSA Campaign 11V345000): For some 2011 M37/M56 vehicles, the tire placard and owner's manual contained incorrect tire inflation pressure specifications.
• ABS Actuator Issue (NHTSA Campaign 16V301000): This broader recall affected many Nissan and Infiniti models from various years, including the 2011 M37/M56. It involved a potential leak of brake fluid from the ABS actuator, which could compromise braking performance.

Long-term durability is generally good, with the VQ engine being a robust powerplant. However, proactive maintenance, especially regarding fluids and suspension components, is key to sustained reliability.

How long will the 2011 Infiniti M37 last?

With diligent maintenance and average driving habits, the 2011 Infiniti M37 is capable of providing many years of service, often reaching well over 150,000 to 200,000 miles. Its robust VQ37VHR engine and seven-speed automatic transmission are generally known for their long-term durability, provided regular oil changes and transmission fluid services are performed. Many owners report significant mileage without major powertrain issues.

However, over time, certain weaknesses emerge. Suspension components like bushings, struts, and sway bar links will eventually wear out, requiring replacement to maintain ride comfort and handling. Brakes remain a consistent maintenance item, and original equipment pads can contribute to rotor wear. As the vehicle ages, minor electrical sensor failures or issues with the infotainment system's responsiveness can also occur. The plastic heater hose connector is another known component that can become brittle and fail, leading to coolant leaks. Overall, it's a durable vehicle, but routine preventative maintenance is crucial for extended longevity.

What Technology & Safety Features are Included?

The 2011 Infiniti M37 was well-equipped with a respectable array of built-in technology, entertainment, and safety features for its time, with even more available through optional packages. Standard amenities included a 7-inch display, a six-speaker audio system with a CD player, auxiliary input, and iPod connectivity, along with Bluetooth phone integration. Keyless ignition/entry, dual-zone automatic climate control, and a rearview camera were also standard, enhancing convenience and safety.

For those seeking more advanced tech, the Premium Package added an 8-inch touchscreen navigation system, a hard-drive music server, satellite radio, and an upgraded Bose 10-speaker audio system. The top-tier Deluxe Touring Package further elevated the audio experience with a premium Bose Studio Surround sound system boasting 16 speakers.

In terms of safety and driver-assistance, all M37 models came standard with essential features like anti-lock brakes (ABS), traction control, stability control, front-seat side airbags, full-length side curtain airbags, and active front head restraints. The standard rearview camera provided crucial assistance during parking maneuvers.

The optional Technology Package significantly bolstered driver assistance capabilities, including advanced systems such as adaptive cruise control (Intelligent Cruise Control), a blind-spot warning system that could also intervene (Blind Spot Intervention System), lane departure warning and prevention (Lane Departure Prevention), forward collision warning, distance control assist, and adaptive headlights that swivel with steering input. This package also integrated an advanced climate control system with an air purifier.

Regarding crash-test ratings, the 2011 Infiniti M37 performed commendably in tests conducted by the Insurance Institute for Highway Safety (IIHS), earning the highest rating of "Good" in the Moderate Overlap Front, Side, Roof Strength, and Head Restraints & Seats categories. The National Highway Traffic Safety Administration (NHTSA) did not publish an overall 5-star safety rating for the 2011 M37 model year.

What Colors Options are Available?

2011 Infiniti M37 Prices and Market Value

When new, the 2011 Infiniti M37 had a starting MSRP of approximately $46,250 for the RWD model and around $48,400 for the M37x AWD variant. Fully optioned models, especially with the Premium, Sport, and Technology packages, could easily push the price into the $55,000 to $60,000 range. Like many luxury sedans, the M37 experienced significant depreciation, particularly in its initial years, making it an excellent value on the used market today.

Currently, used market prices for the 2011 Infiniti M37 typically range from approximately $7,000 for higher-mileage examples in average condition to $15,000 or more for well-maintained, lower-mileage vehicles with desirable option packages. Factors heavily affecting its current resale value include the overall condition of the car, its mileage, a complete and verifiable service history, the presence of sought-after option packages (like the Premium or Technology packages), and whether it's an AWD (M37x) model. Accident history can significantly diminish its value.

2011 Infiniti M37 Cost of Ownership

Owning a 2011 Infiniti M37 generally falls into the moderately costly category, not as expensive as some European luxury counterparts but certainly more than a mainstream sedan. Insurance premiums are typically higher due to its luxury and performance classification. The M37 requires premium gasoline, and its 18-20 mpg combined fuel economy means recurring fuel costs will be significant. Maintenance costs are generally reasonable for a luxury brand, with scheduled services at Infiniti dealerships being pricier than independent shops. Repair costs can be substantial for major components, as parts are priced at luxury levels, though the VQ engine's reliability can mitigate this. Over the long term, expect higher costs for tires, brakes, and eventual replacement of worn suspension components. It's a rewarding car to own, but budget accordingly for premium fuel and luxury-tier upkeep.

How Does the 2011 Infiniti M37 Compare to Other Sedan?

The 2011 Infiniti M37 positions itself as a strong contender in the mid-size luxury sedan segment, offering a compelling alternative to established German and Japanese rivals. Here's how it stacks up:

• Performance: The M37, with its 330-hp V6, delivers robust acceleration and engaging driving dynamics. It feels more agile and sporting than a Mercedes-Benz E350 (268 hp for 2011) or a Lexus GS 350 (303 hp), which prioritize comfort and refinement, respectively. While a BMW 535i (300 hp turbo I6) from the same year might offer slightly more precise steering feedback and a more balanced chassis, the M37 provides a very satisfying, sporty experience, often comparable to a Cadillac CTS (304 hp V6).
• Features: Infiniti equipped the M37 generously, often including features as standard that were expensive options on German competitors. Its optional Technology and Premium packages rivaled the advanced tech offerings from BMW, Mercedes, and Audi, including adaptive cruise control and blind-spot intervention. The interior quality and material choices are very competitive with Lexus and often perceived as a step above the Cadillac.
• Reliability: Historically, the Infiniti M37, leveraging Nissan's robust VQ engine, has generally demonstrated good reliability, often surpassing that of many German rivals which can be prone to more complex electrical or mechanical issues as they age. It stands in good stead with the Lexus GS for long-term dependability, generally requiring less costly repairs than an aging BMW or Mercedes.
• Price (Used Market): This is where the M37 truly shines as a value proposition. It has depreciated more significantly than its BMW, Mercedes, and Audi counterparts, meaning a well-maintained 2011 M37 can be acquired for considerably less money. Used prices are often on par with or slightly below a Lexus GS or Cadillac CTS of similar vintage.

Recommended Alternatives:

• For similar sportiness and value: Consider the 2011 Cadillac CTS.
• For paramount reliability and refinement: The 2011 Lexus GS 350 is an excellent choice.
• If driving dynamics are paramount and budget allows for potentially higher maintenance: A 2011 BMW 535i is a strong contender.
• If ultimate comfort is key: The 2011 Mercedes-Benz E350 remains a benchmark.

The M37 strikes a great balance, offering compelling performance, a luxurious interior, and good reliability at a very attractive used price point.

Final Verdict: Is the 2011 Infiniti M37 a Good Sedan?

The 2011 Infiniti M37 represents an excellent value proposition as a used luxury sports sedan. It is ideal for the discerning buyer who desires robust performance, a well-appointed and comfortable cabin, and distinctive styling, without the premium price tag of its German rivals on the used market. This vehicle is certainly worth buying under the right conditions.

It shines as a used vehicle, having already undergone significant depreciation. When considering a purchase, prioritize models with a complete and verifiable service history, and a pre-purchase inspection by a trusted mechanic is essential. The Premium Package is highly recommended for its upgraded technology and comfort features like navigation and heated/cooled seats, offering a truly luxurious experience. Enthusiasts might seek out the Sport Package for its enhanced dynamics. While generally reliable, prospective owners should budget for premium fuel and typical luxury vehicle maintenance and repair costs. For someone seeking a powerful, comfortable, and stylish luxury sedan that offers strong reliability for its class at an attractive used price, the 2011 Infiniti M37 is a compelling choice.
