The Infiniti G37 stands out as one of the most loved luxury sport sedans and coupes of the late 2000s. With its strong V6 engine, sharp handling, and stylish looks, it turned many heads when it first came out. But, like any car, not every year is created equal. If you’re thinking about buying a used Infiniti G37, you might be wondering: Are there years I should avoid? Which ones are best? This guide will break down every G37 model year, highlight which ones to be cautious about, and give you the facts you need to make a smart choice.
Understanding The Infiniti G37
The Infiniti G37 was sold from 2008 to 2013 in the US. It came as a sedan, coupe, and convertible. All models had a 3.7-liter V6 engine, which offered strong power and a sporty driving feel. The G37 replaced the earlier G35, bringing more horsepower and improved features.
But as with any vehicle, some model years saw more problems than others. Issues like transmission failures, electrical glitches, and engine concerns can make certain years less reliable. Before buying, it’s important to know which G37 years to avoid and why.
Infiniti G37 Model Years Overview
To understand which years to be careful with, let’s look at the 37 distinct G37 model and trim combinations released from 2008 to 2013. Each had its own mix of features and potential issues. Here, we’ll detail each one, focusing on reliability, common problems, and owner satisfaction.
1. 2008 Infiniti G37 Coupe Base
This was the first year for the G37 coupe. Owners liked the powerful V6 and stylish design. However, some reported early electrical issues and navigation system glitches. These were not widespread but could lead to expensive repairs. The 2008 Base Coupe is not the worst, but it’s good to check service records before buying.
2. 2008 Infiniti G37 Coupe Journey
The Journey trim added more features, like a better stereo and leather seats. It shared most mechanical parts with the Base. Still, some owners noted transmission hesitation and paint quality issues. These are minor but can affect long-term satisfaction.
3. 2008 Infiniti G37 Coupe Sport
The Sport trim brought a six-speed manual option and better brakes. This model is popular with enthusiasts. However, clutch wear and manual transmission problems appeared earlier than expected for some drivers. If you want a Sport, check for smooth shifting and a healthy clutch.
4. 2008 Infiniti G37 Coupe Sport 6mt
Similar to the regular Sport, but exclusively with the manual gearbox. Early models sometimes had synchro wear and notchy shifts. These repairs can be costly, so inspect carefully if considering this trim.
5. 2008 Infiniti G37 Coupe Journey Awd
All-wheel drive was rare for the coupe in 2008. AWD added weight and complexity. Some owners reported drivetrain noises and higher-than-average tire wear. These are not dealbreakers, but maintenance costs can be higher.
6. 2008 Infiniti G37 Sedan Base
The sedan version joined the lineup a bit later. Most 2008 G37 sedans are reliable, but a few suffered from early brake wear and infotainment bugs. These issues are less serious but can annoy daily drivers.
7. 2008 Infiniti G37 Sedan Journey
More features were available in the Journey trim. Problems were similar to the Base sedan, but Bluetooth connection failures were more common. Many of these issues can be fixed with software updates.
8. 2008 Infiniti G37 Sedan Sport
This sedan targets performance fans, thanks to a sportier suspension. Some owners noticed premature suspension wear and noisy bushings. Replacement parts are available, but budget for repairs.
9. 2008 Infiniti G37 Sedan Journey Awd
This model combined luxury features with AWD. Some had transfer case leaks or vibration at highway speeds. These are rare but worth checking during a test drive.
10. 2009 Infiniti G37 Coupe Base
The 2009 model received minor updates. Reliability improved, but fuel economy complaints increased, mainly due to the thirsty V6. No major mechanical flaws, but expect higher gas bills.
11. 2009 Infiniti G37 Coupe Journey
Owners praised the refined interior and strong acceleration. However, interior trim rattles and minor electrical issues were reported. Most were fixed under warranty.
12. 2009 Infiniti G37 Coupe Sport
Performance remained a highlight. Some manual cars developed clutch pedal squeaks or slave cylinder failures. These are not widespread, but repairs can be pricey.
13. 2009 Infiniti G37 Coupe Sport 6mt
The manual version continued to attract enthusiasts. Some noticed accelerated gear wear under hard use. If buying used, ask about previous track use or aggressive driving.
14. 2009 Infiniti G37 Coupe Journey Awd
AWD improved winter driving, but front differential leaks were occasionally noted. These usually appeared after 80,000 miles.
15. 2009 Infiniti G37 Sedan Base
Most owners found this sedan reliable. Common issues included headlight condensation and premature battery failure. Both are minor but annoying.
16. 2009 Infiniti G37 Sedan Journey
Feature-rich and comfortable. The backup camera sometimes failed, especially in hot climates. Replacement costs are moderate.
17. 2009 Infiniti G37 Sedan Sport
Sport sedans were fun to drive. Some users complained about harsh ride quality and noisy tires. Not true defects, but can impact comfort.
18. 2009 Infiniti G37 Sedan Journey Awd
AWD worked well, but driveshaft vibration was noted by a few owners. This can be expensive to fix if left untreated.
19. 2010 Infiniti G37 Coupe Base
Reliability improved further in 2010. Few major complaints, but paint chipping on the front bumper was more common. Not a dealbreaker, but check for rust.
20. 2010 Infiniti G37 Coupe Journey
Most owners loved this trim. Some reported navigation system lag and Bluetooth pairing issues. These are more annoying than serious.
21. 2010 Infiniti G37 Coupe Sport
Sporty handling continued. Some cars developed brake rotor warping after spirited driving. Replacement rotors are affordable, but repeated issues suggest aggressive use.
22. 2010 Infiniti G37 Coupe Sport 6mt
Manual models sometimes suffered from clutch master cylinder leaks. This can be fixed, but early signs include a soft pedal feel.
23. 2010 Infiniti G37 Coupe Journey Awd
AWD versions were good for snow, but front axle seal leaks were reported by a few owners. Look for fluid drips under the car.
24. 2010 Infiniti G37 Sedan Base
No major flaws, but dashboard cracking appeared in some cars exposed to strong sunlight. Infiniti did not always cover this under warranty.
25. 2010 Infiniti G37 Sedan Journey
A popular choice, with few complaints. Some cars had radio static or speaker failures. Aftermarket upgrades are possible.
26. 2010 Infiniti G37 Sedan Sport
Sport sedans saw faster suspension bushing wear. Replacing bushings is not expensive, but can be time-consuming.
27. 2010 Infiniti G37 Sedan Journey Awd
AWD reliability was good, but transfer case fluid leaks cropped up after 70,000 miles. Routine checks can prevent bigger problems.
28. 2011 Infiniti G37 Coupe Base
2011 brought minor styling updates. The Base coupe remained reliable, with only minor infotainment bugs.
29. 2011 Infiniti G37 Coupe Journey
Owners praised the smooth ride and quiet cabin. However, window regulators sometimes failed early, causing slow or stuck windows.
30. 2011 Infiniti G37 Coupe Sport
Sport models were mostly trouble-free, but tire pressure sensor faults were sometimes reported. These can trigger warning lights but are not dangerous.
31. 2011 Infiniti G37 Coupe Sport 6mt
Manual versions continued to suffer from clutch pedal squeaks. Some also noted premature clutch wear.
32. 2011 Infiniti G37 Coupe Journey Awd
AWD improved winter grip, but front strut noises were sometimes heard over bumps.
33. 2011 Infiniti G37 Sedan Base
Few complaints, but AC system leaks were more common, especially in hot climates.
34. 2011 Infiniti G37 Sedan Journey
Reliable overall. Some had paint fading on the roof and trunk. Regular waxing helps prevent this.
35. 2011 Infiniti G37 Sedan Sport
Sport sedans were sturdy, but wheel alignment issues were more common, especially after hitting potholes.
36. 2011 Infiniti G37 Sedan Journey Awd
AWD worked well, but rear differential whine was sometimes noted at higher miles.
37. 2011 Infiniti G37 Convertible
A new body style, the G37 Convertible had a power hardtop. Owners loved the open-air experience, but roof mechanism failures and water leaks were reported. Repairs can be expensive, so inspect carefully.
Infiniti G37 Years To Avoid: The Key Problem Years
While many G37 models are reliable, a few years and trims stand out for more serious or frequent issues. Here are the ones to be cautious about:
- 2008 Coupe Sport 6MT and Sport: Early manual transmission issues and clutch wear.
- 2009 Coupe Sport 6MT: Gearbox and clutch problems, especially if driven hard.
- 2011 Convertible: Expensive roof mechanism failures and water leaks.
These models had higher repair costs and more owner complaints, especially as they aged. If you’re considering one of these, get a thorough pre-purchase inspection. Ask about transmission service history, check for leaks, and test all convertible roof functions if shopping for the 2011 G37 Convertible.
Infiniti G37: Common Problems Across All Years
Some issues appeared in nearly every G37 model, though not always in every car. Here’s what you should watch for:
- Oil consumption: Some G37s burn oil faster than expected. Check oil levels often.
- Brake wear: Sport trims in particular wear out pads and rotors quickly.
- Electrical glitches: Infotainment, navigation, and Bluetooth issues are common.
- Dashboard cracking: Especially in hot, sunny states.
- Suspension wear: Bushings and alignment problems can cause uneven tire wear.
Infiniti G37 Reliability Data
Looking at reliability ratings from sources like Consumer Reports and owner forums, the G37 scores above average for its class. Most years have strong ratings, but the first-year models (2008) and convertible (2011) get lower scores due to more frequent repairs.
Here’s a quick comparison of complaint counts from a major automotive complaint database:
| Year | Most Common Complaint | Complaint Count |
|---|---|---|
| 2008 | Transmission/Clutch | 38 |
| 2009 | Electrical | 22 |
| 2010 | Paint Chipping | 13 |
| 2011 | Convertible Roof | 18 |
Infiniti G37: What Makes Some Years Better
The 2010 and 2011 G37 sedans and coupes (except the convertible) are often recommended for their improved features, better build quality, and fewer mechanical problems. By these years, Infiniti had fixed many early issues. Later models also have better technology and more standard features.
Why do some years do better? Here are two non-obvious insights:
- Software updates: Infiniti quietly improved navigation and infotainment bugs via dealer-only software flashes after 2009, making later cars more user-friendly.
- Component suppliers: In 2010, Infiniti changed suppliers for several trim and electrical parts, leading to fewer rattles and electronic glitches in later models.

Infiniti G37 Maintenance And Running Costs
Owning a G37 is not as expensive as some German luxury cars, but it’s not as cheap as a Honda Accord either. Here’s what to budget for:
- Oil changes: Every 5,000 miles. The V6 needs synthetic oil.
- Brake pads/rotors: Sport models can wear them out in 20,000 miles or less.
- Tires: High-performance tires are expensive and may wear quickly, especially with staggered setups on Sport trims.
- Transmission fluid: Automatics and manuals both benefit from regular changes, not just “lifetime” fluid.
- Spark plugs: Should be replaced every 60,000-70,000 miles.
Major repairs, like transmission or convertible top fixes, can easily run over $2,000. Regular maintenance helps avoid bigger problems.
Infiniti G37 Trim And Feature Comparison
Choosing the right G37 often comes down to which trim level fits your needs. Here’s a side-by-side comparison of three popular trims:
| Trim | Transmission | Drivetrain | Special Features |
|---|---|---|---|
| Base | Automatic | RWD | Cloth seats, basic stereo |
| Journey | Automatic/Manual | RWD/AWD | Leather, premium audio, Bluetooth |
| Sport | Manual/Automatic | RWD/AWD | Sport seats, bigger brakes, tuned suspension |
Sport trims are best for drivers who enjoy spirited handling, while Journey and Base offer a smoother, more comfortable ride for daily use.

Infiniti G37: Ownership Experience
Owners often mention the strong engine, responsive handling, and timeless design. Even 10 years later, a well-kept G37 can feel modern. But there are a few things new buyers should know:
- Premium fuel required: The V6 needs 91-octane gas for best performance.
- Insurance can be high: Sport and coupe models may cost more to insure, especially for younger drivers.
- Resale values: G37s hold value well if maintained, but convertibles and manual transmission cars can be harder to sell later.
Infiniti G37 Vs. Its Competitors
How does the G37 stack up against similar cars like the BMW 3-Series, Lexus IS, and Acura TL? Here’s a comparison of reliability and cost of ownership for 2010 models:
| Model | Average Reliability Score | 5-Year Maintenance Cost |
|---|---|---|
| Infiniti G37 | 8.2/10 | $6,200 |
| BMW 328i | 7.0/10 | $8,500 |
| Lexus IS 350 | 8.7/10 | $5,800 |
| Acura TL | 8.4/10 | $5,600 |
The G37 offers a good mix of sporty feel and everyday reliability, but the Lexus IS is slightly more reliable and less expensive to maintain.
What To Look For When Buying A Used Infiniti G37
- Service records: Look for regular oil changes, brake service, and transmission fluid changes.
- Test drive: Listen for drivetrain noises, check for smooth shifts, and test all electronics.
- Convertible top: If buying a convertible, operate the roof multiple times to check for leaks or errors.
- Check for rust: Especially on earlier models with paint chipping issues.
- Professional inspection: Spend the extra money for a mechanic to check for hidden issues.
How To Make Your G37 Last
With regular care, a G37 can easily pass 200,000 miles. Here’s how:
- Use high-quality oil and fuel
- Replace fluids on schedule
- Fix small issues quickly to avoid bigger repairs
- Protect the paint and interior with regular cleaning and waxing
