The 2011 Infiniti G37 is a luxury sports vehicle offered as a Coupe, Sedan, and Convertible. Part of Infiniti's G-series, which ran from 2008 to 2013 under the G37 name, it stood out for its potent 3.7L V6 engine, engaging driving dynamics, and sleek design. With new prices ranging from approximately $35,000 to $52,000 depending on trim and body style, it offered a compelling blend of performance and luxury, making it a popular alternative to German rivals.
The Good
The G37 boasts thrilling V6 performance and athletic handling, appealing to emotional drivers. Its sophisticated design exudes luxury.

What Problems Does the 2011 Infiniti G37 Have?
While generally reliable, the 2011 Infiniti G37 has a few frequently reported problems and long-term concerns worth noting. The most significant is the potential for a gallery gasket failure in the 3.7L VQ37VHR engine. This issue, more prevalent in earlier VQ37 engines (including some 2011 models), leads to a drop in oil pressure and can cause a "check engine" light with P0011/P0021 codes. Repair is labor-intensive and costly. Owners considering a 2011 G37 should inquire if this has been addressed.
Another common issue, often related to earlier G-series, is Electronic Steering Column Lock (ESCL) failure, which can prevent the vehicle from starting. Although Infiniti issued extended warranties and recalls for some VINs, it's a known point of failure.
Other reported issues include window regulator failures, leading to slow or inoperable power windows, and occasional clear coat peeling or paint durability issues as the vehicle ages. Owners of Sport models may experience accelerated brake wear due to larger components and aggressive driving. Similarly, the factory alignment on Sport models can contribute to uneven and rapid tire wear.
Regarding recalls, the 2011 G37 was affected by the widespread Takata airbag inflator recall (NHTSA Campaign Number: 16V244000), concerning the passenger front air bag inflator rupturing. Additionally, there was a recall (NHTSA Campaign Number: 10V473000) regarding the passenger air bag on/off switch possibly not detecting small adults or children. Prospective buyers should always verify that all open recalls have been completed by checking the vehicle's VIN with Infiniti or the NHTSA website.
Long-term reliability is generally good for the powertrain, but these specific issues can lead to expensive repairs if not addressed preventatively or if they manifest after purchase. Regular maintenance is key to mitigating other age-related wear.

How long will the 2011 Infiniti G37 last?
With proper and diligent maintenance, a 2011 Infiniti G37 can reliably serve its owners for 150,000 to 200,000 miles or even more. Many enthusiastic owners report reaching these high mileages with their VQ-powered G37s, showcasing the inherent durability of its engine and automatic transmission. The robust chassis and quality interior components generally hold up well over time, contributing to its long-term appeal.
However, long-term weaknesses can emerge. Suspension components like bushings, control arms, and shock absorbers will naturally wear out, impacting ride comfort and handling precision. Minor electrical issues, such as failing window regulators, door lock actuators, or infotainment glitches, can also occur with age. While the VQ engine is strong, the aforementioned gallery gasket issue, if present and unaddressed, remains a critical long-term concern that can significantly shorten its lifespan or necessitate a costly repair.

What Technology & Safety Features are Included?
The 2011 Infiniti G37 came equipped with a solid array of built-in technology, entertainment, and safety features for its era, with several desirable options. Standard tech included Infiniti's Intelligent Key with push-button ignition, automatic climate control, a 6-speaker audio system with auxiliary input, and a multi-function display. Moving up to the Journey trim or opting for packages introduced a 7-inch color display (non-touch), a rearview monitor, Bluetooth hands-free phone system, and a USB/iPod interface.
For entertainment, the optional Navigation Package added a hard-drive-based navigation system with voice recognition, real-time traffic (NavTraffic), and a 9.3 GB Music Box hard drive for storing music. An 11-speaker Bose premium audio system was also available, significantly enhancing the in-car audio experience. While functional and advanced for 2011, the infotainment interface lacks the graphical sophistication and modern connectivity (like Apple CarPlay/Android Auto) of today's systems.
Driver-assistance features were advanced for its time, primarily bundled in the Technology Package. This included Intelligent Cruise Control, which maintains a set distance from the vehicle ahead, Lane Departure Warning (LDW) to alert drivers if they drift from their lane, and Forward Collision Warning (FCW) with Intelligent Brake Assist (IBA), which can apply the brakes to help mitigate a potential front-end collision.
Safety features were comprehensive, with standard equipment including anti-lock brakes (ABS), electronic brakeforce distribution (EBD), brake assist (BA), Vehicle Dynamic Control (VDC) with a Traction Control System (TCS), front-seat active head restraints, and a full complement of airbags (front, front-side, and full-length curtain airbags). A Tire Pressure Monitoring System (TPMS) was also standard.
In terms of crash-test ratings, the 2011 Infiniti G37 Sedan received favorable scores. The National Highway Traffic Safety Administration (NHTSA) awarded the sedan 5 stars for side-impact protection and 4 stars for rollover resistance. The Insurance Institute for Highway Safety (IIHS) gave the 2011 G37 Sedan "Good" ratings in its moderate overlap front, side impact, roof strength, and head restraints & seats tests. Note that the small overlap front test was not yet standard for this model year.

2011 Infiniti G37 Prices and Market Value
When new in 2011, the Infiniti G37 carried Manufacturer's Suggested Retail Prices (MSRPs) ranging from approximately $35,000 to $44,000 for the Sedan, $37,000 to $46,000 for the Coupe, and $46,000 to $52,000 for the Convertible, depending on trim and options. Today, in the used market (late 2023/early 2024), prices for a 2011 G37 generally range from $7,000 to $15,000+, reflecting significant depreciation over its lifespan. Exceptionally clean, low-mileage examples, especially Sport Coupes, can command higher prices.

2011 Infiniti G37 Cost of Ownership
Owning a 2011 Infiniti G37 involves moderate to high long-term costs. Insurance rates are typically higher due to its luxury sports car classification. It requires premium gasoline, which contributes to higher fuel costs, especially for high-mileage drivers, given its combined MPG in the high teens to mid-20s. Routine maintenance is comparable to other V6 luxury cars, but specialized parts or fluids can be pricier. Repair costs can be significant if major issues like the gallery gasket failure occur, often requiring specialized labor. While offering excellent value as a used purchase, the G37 is not an "economical" car to own. Buyers should budget for premium fuel, potentially elevated insurance, and the possibility of expensive repairs, making it a moderately costly but rewarding vehicle for its segment.

Final Verdict: Is the 2011 Infiniti G37 a Good Sedan?
The 2011 Infiniti G37 is an excellent choice for individuals seeking a compelling blend of thrilling performance, luxury amenities, and distinctive style without the exorbitant price tag of European rivals. It appeals to driving enthusiasts who appreciate a potent V6 engine, engaging rear-wheel-drive dynamics, and a premium, comfortable interior. It's also suitable for those desiring a sophisticated daily driver (sedan) or a sporty weekend escape (coupe/convertible).
It is absolutely worth buying, but strictly as a used vehicle. Its significant depreciation makes it an outstanding value in the second-hand market. Prospective buyers should prioritize models with a complete service history and strongly consider a pre-purchase inspection by a mechanic familiar with Infinitis, especially to check for the known gallery gasket issue or steering lock concerns.
