Hey guys! Let's dive into the 2008 Infiniti G35XS and talk about something super important: reliability. If you're thinking about buying one of these or already own one, you'll want to know what to expect. The G35XS is a sporty and stylish sedan, but like any car, it has its quirks. We're going to break down the common issues and overall reliability so you can make an informed decision.

Overall Reliability of the 2008 Infiniti G35XS

When it comes to the 2008 Infiniti G35XS reliability, it generally holds up pretty well, but there are definitely some areas to watch. The G35 series, in general, is known for being fairly robust, and the XS trim is no exception. However, keep in mind that a 2008 model is getting up there in age, so maintenance and how well the previous owner cared for it play a huge role.

Engine Performance: The VQ35HR engine in the 2008 G35XS is generally considered reliable. It's a naturally aspirated 3.5-liter V6 that delivers plenty of power. However, like all engines, it’s not immune to issues. Regular oil changes and keeping an eye on coolant levels are crucial. Some owners have reported issues with oil consumption, so that's something to monitor. Also, listen for any unusual noises, as these could indicate potential problems down the road. Remember, preventative maintenance is your best friend.

Transmission: The automatic transmission in the G35XS is usually reliable, but it's worth checking for smooth shifting. Jerky or hesitant shifts can be signs of trouble. Regular transmission fluid changes are essential to keep everything running smoothly. If you're test driving one, pay close attention to how it shifts through all the gears, both up and down. Any slipping or unusual behavior should be a red flag.

Common Issues: Despite its reliability, the 2008 G35XS has some common issues that owners should be aware of. Things like the valve cover gaskets leaking, the timing chain going bad, or the evaporative emissions system needing attention are things that you should keep in mind. We’ll go into more detail on these in the next section.

Common Problems with the 2008 Infiniti G35XS

Okay, let's get into the nitty-gritty. Knowing the common problems with the 2008 Infiniti G35XS can help you spot potential issues early and save you some serious headaches (and money!). Here are some of the things that pop up frequently:

Valve Cover Gasket Leaks: This is a pretty common issue with the VQ35HR engine. The valve cover gaskets can start to leak oil, which can drip onto the exhaust and cause a burning smell. It's not a super serious issue if caught early, but if left unattended, it can lead to bigger problems. Keep an eye out for oil spots under the car or that telltale burning smell. Replacing the valve cover gaskets is a relatively straightforward repair, but it's best to get it done sooner rather than later.

Timing Chain Issues: Another potential issue is the timing chain. Over time, the timing chain can stretch or the tensioners can wear out, leading to timing issues. Symptoms can include rough running, a check engine light, or a rattling noise from the engine. This is a more serious repair, as it involves disassembling part of the engine. If you suspect a timing chain issue, it's best to take it to a qualified mechanic right away.

Evaporative Emissions (EVAP) System Problems: The EVAP system helps prevent fuel vapors from escaping into the atmosphere. Common issues include a loose or faulty gas cap, cracked hoses, or a failing EVAP canister. Symptoms can include a check engine light and a fuel smell. Diagnosing EVAP system problems can sometimes be tricky, as there are many potential causes. A smoke test can help pinpoint leaks in the system.

Electrical Issues: Some owners have reported electrical issues, such as problems with the power windows, door locks, or the navigation system. These can sometimes be caused by a faulty Body Control Module (BCM) or wiring issues. Electrical problems can be frustrating to diagnose, so it's best to have them checked out by a qualified technician.

Suspension and Steering: Given the age of the car, suspension components like shocks, struts, and control arm bushings may start to wear out. This can lead to a bumpy ride, poor handling, and unusual noises. Also, check the power steering system for leaks or unusual noises. Replacing worn suspension components can significantly improve the ride quality and handling of the G35XS.

Maintenance Tips for the 2008 Infiniti G35XS

Alright, let's talk about keeping your 2008 Infiniti G35XS in tip-top shape. Regular maintenance is key to maximizing reliability and preventing those pesky problems we just discussed. Here’s what you need to focus on:

Regular Oil Changes: This is the most important thing you can do for your engine. Follow the manufacturer's recommended oil change interval, and use a high-quality synthetic oil. Keep an eye on the oil level and check for any signs of oil leaks. Remember, the VQ35HR engine can be sensitive to oil quality and level, so don't skimp on this.

Transmission Fluid Changes: As mentioned earlier, regular transmission fluid changes are essential for keeping the transmission shifting smoothly. Follow the manufacturer's recommended interval, and use the correct type of fluid. If you notice any signs of transmission problems, such as slipping or rough shifting, have it checked out right away.

Coolant Flushes: Coolant helps regulate the engine temperature and prevents corrosion. Over time, coolant can become contaminated and lose its effectiveness. Regular coolant flushes will help keep the cooling system in good condition and prevent overheating. Check the coolant level regularly and look for any signs of leaks.

Brake Maintenance: Keep an eye on the brake pads and rotors, and replace them as needed. Also, flush the brake fluid every few years to remove moisture and contaminants. Properly maintained brakes are essential for safety, so don't neglect them.

Tire Care: Check the tire pressure regularly and rotate the tires every 6,000 to 8,000 miles. This will help ensure even wear and prolong the life of the tires. Also, inspect the tires for any signs of damage, such as cuts or bulges.

Regular Inspections: Have a qualified mechanic inspect your G35XS regularly. They can spot potential problems early and help you prevent costly repairs down the road. A thorough inspection should include checking the engine, transmission, brakes, suspension, and electrical system.

Is the 2008 Infiniti G35XS a Good Car?

So, is the 2008 Infiniti G35XS a good car? Overall, yes! It offers a great blend of performance, style, and luxury. The VQ35HR engine is powerful and responsive, and the G35XS handles well. However, it's important to be aware of the potential reliability issues and to factor in the cost of maintenance and repairs.

If you're considering buying a 2008 G35XS, here are a few things to keep in mind:

Get a Pre-Purchase Inspection: Before you buy, have a qualified mechanic inspect the car. They can identify any existing problems and give you an idea of the overall condition of the car. This is especially important for older cars, as they may have hidden issues.

Check the Maintenance Records: Ask to see the maintenance records. This will give you an idea of how well the car has been cared for. Look for regular oil changes, transmission fluid changes, and other routine maintenance.

Test Drive the Car: Take the car for a test drive and pay attention to how it performs. Check for smooth shifting, good acceleration, and responsive handling. Listen for any unusual noises or vibrations.

Consider the Mileage: A car with high mileage may have more wear and tear than a car with lower mileage. However, a well-maintained car with high mileage can still be a good buy.

Final Thoughts

The 2008 Infiniti G35XS can be a fantastic car if you know what to look for and are prepared to keep up with maintenance. The key is to do your homework, get a thorough inspection, and be proactive about addressing any potential issues. With a little care, your G35XS can provide years of driving pleasure. Happy driving!
