We're diving deep into the G35's reliability, covering common problems, what to look out for, and whether this sporty sedan or coupe is a smart buy. Trust me, understanding the reliability of a car can save you a ton of headaches (and cash!) down the road. So, let's get into it, shall we?

The Infiniti G35: A Quick Overview

Before we jump into the nitty-gritty of reliability, let's quickly recap what makes the Infiniti G35 so appealing. This car, produced from 2003 to 2008 (with some minor variations throughout the years), was Infiniti's answer to the BMW 3 Series and the Mercedes-Benz C-Class. It offered a blend of luxury, performance, and style that made it a hit with driving enthusiasts. You had the choice of a sleek sedan or a sporty coupe, both powered by a potent V6 engine. The G35 was known for its responsive handling, comfortable interior, and a design that still looks pretty darn good today. But all that glitz and glam doesn't mean much if the car spends more time in the shop than on the road, right?

Common Infiniti G35 Problems and Issues

Alright, let's get to the meat of the matter: the potential problems you might encounter with a used G35. No car is perfect, and the G35 has its fair share of common issues. Knowing about these problems upfront can help you make an informed decision and potentially save you from some unexpected repair bills. We'll break down the most common issues by category.

Engine and Powertrain Problems

• Oil Consumption: This is probably the most widely reported issue with the G35's VQ35DE engine. Some owners experience excessive oil consumption, which can lead to engine damage if not addressed. Keep an eye on your oil levels, and be prepared to top it off between oil changes. Regular oil changes are also important to help mitigate this issue.
• Oil Leaks: Oil leaks are another common concern, often originating from the valve covers, oil pan, or rear main seal. These leaks can be annoying and, if left unattended, can lead to low oil levels and engine damage. Check for oil spots under the car and get them fixed ASAP.
• Catalytic Converter Issues: The catalytic converters on the G35 can sometimes fail, especially in older models or those with high mileage. This can trigger the check engine light and impact performance. Replacing catalytic converters can be expensive, so it's a good idea to have them inspected during a pre-purchase inspection.
• Water Pump Failure: The water pump is a critical component of the cooling system, and it can fail over time. A failing water pump can lead to overheating, which can cause significant engine damage. Keep an eye out for any signs of coolant leaks or overheating.

Transmission Problems

• Automatic Transmission Issues: While the G35's automatic transmission is generally reliable, some owners have reported issues like hard shifting or shuddering. Regular transmission fluid changes are crucial to keeping the transmission healthy. If you notice any unusual behavior from the transmission, get it checked out promptly.
• Manual Transmission Problems: The manual transmission is generally robust, but some owners have reported problems with the clutch or the synchronizers. Clutch replacement is a wear-and-tear item, but problems with the synchronizers can be more complex and costly to repair.

Electrical Issues

• Window Regulator Failure: The window regulators on the G35 are known to fail, causing the windows to stop working. This is a fairly common issue and can be frustrating. Replacing the window regulator can be a DIY project or can be done by a mechanic.
• Infotainment System Glitches: The infotainment system in the G35 can be prone to glitches, like freezing or malfunctioning. These issues are generally more of an annoyance than a major problem, but they can still be frustrating. Restarting the system or updating the software can sometimes fix these issues.
• Electrical Gremlins: Like many cars, the G35 can sometimes experience electrical gremlins, such as malfunctioning lights or sensors. These issues can be tricky to diagnose and repair.

Suspension and Steering Problems

• Suspension Component Wear: The G35's suspension components, such as control arms, bushings, and shocks, can wear out over time. This can lead to a less comfortable ride and impact handling. Replacing worn suspension components is a standard maintenance item.
• Power Steering Issues: Some owners have reported issues with the power steering system, such as leaks or pump failure. These issues can make it harder to steer the car and can be costly to repair.

What to Look for When Buying a Used Infiniti G35

So, you're still interested in a G35? Awesome! But before you hand over your hard-earned cash, you'll want to do your homework and inspect the car thoroughly. Here's a checklist to help you:

• Pre-Purchase Inspection (PPI): This is the most important step. Take the car to a trusted mechanic for a thorough inspection. They can identify potential problems that you might miss. It's money well spent and can save you from a major headache. The mechanic should check the engine, transmission, suspension, brakes, and electrical systems.
• Check the Carfax or Similar Report: Get a vehicle history report to check for accidents, title issues, and maintenance records. This can give you valuable insights into the car's past.
• Inspect the Exterior: Look for any signs of body damage, rust, or mismatched paint. These can be indicators of previous accidents or poor maintenance.
• Check the Interior: Inspect the interior for wear and tear, especially the seats, dashboard, and carpets. Make sure all the features, such as the power windows, sound system, and climate control, are working properly.
• Test Drive: Take the car for a thorough test drive. Pay attention to how the engine runs, how the transmission shifts, and how the car handles. Listen for any unusual noises, such as clunking or squealing. Check the brakes and make sure they are responsive.
• Check for Oil Leaks: Look for any signs of oil leaks under the car and around the engine. Oil leaks can be a sign of a more serious problem.
• Check the Oil Level: Check the oil level and the condition of the oil. Low oil levels can be a sign of excessive oil consumption or leaks.
• Ask About Maintenance Records: Ask the seller for any maintenance records. This can give you a better understanding of how well the car has been maintained.
• Negotiate the Price: Based on your findings during the inspection and test drive, negotiate the price accordingly. Be realistic about the car's condition and any potential repairs that might be needed.
