Common Problems and Issues

Alright, let's get down to brass tacks: what kind of problems do 2004 Infiniti FX35 owners often face? Understanding these common issues is a huge step in assessing the car's reliability. Here’s a breakdown of the most reported problems. Knowing these issues will help you prepare and take care of them before they leave you stranded.

Engine Troubles

The engine is the heart of any car, and for the FX35, it's generally pretty solid, but there are some things to keep an eye on. One common issue is oil consumption. Some owners report that the engine tends to burn oil, especially as the car ages. This can lead to decreased engine performance and potential damage if the oil level gets too low. Regularly checking your oil levels and topping them up as needed is critical to avoiding serious engine problems. Oil leaks from valve cover gaskets are another problem you should be looking for. When these gaskets go bad, it can lead to oil leaks, which can damage the engine and cause other problems. The engine is great, but you need to be taking care of it.

Another thing to be aware of is the potential for catalytic converter failure. Over time, these components can degrade, leading to reduced engine performance and, potentially, expensive replacement costs. Regular maintenance and using the correct type of fuel can help extend the life of your catalytic converter.

Transmission Concerns

The transmission in the 2004 Infiniti FX35 is generally reliable, but like any mechanical component, it can have its issues. One of the common problems reported by owners is transmission shudder. This can be caused by various issues, including torque converter problems. If you experience shuddering during acceleration or when shifting gears, it's essential to have your transmission checked by a qualified mechanic to prevent further damage. Regularly changing the transmission fluid can also help extend its life.

Another thing to watch for is transmission leaks. Over time, seals and gaskets can wear out, leading to leaks. Keeping an eye out for any fluid on the ground beneath your car is important and getting any leaks fixed promptly can prevent more severe and expensive problems down the road.

Electrical System Woes

Electrical gremlins are unfortunately common in many cars of this era, and the FX35 is no exception. Owners have reported a range of electrical issues, from minor annoyances to more significant problems. One common issue is problems with the power windows. Sometimes, the windows can become slow or stop working altogether. This is often due to problems with the window motors or the switches. Checking the fuses and relays is a good first step in diagnosing these problems. But if the problem persists, you may need to replace the motor or switch.

Another electrical issue that owners face is problems with the infotainment system. This can include anything from the screen freezing to the radio not working. These problems can be frustrating, but sometimes, they can be fixed with a simple software reset or by replacing a faulty component. The FX35 has a lot of electronic parts that may fail.

Suspension and Steering Issues

Since this car is an SUV, you should be paying attention to the suspension and steering system. These components take a beating. The FX35's suspension and steering systems can develop issues over time. One common problem is the wear and tear of suspension components, such as shocks, struts, and bushings. This wear and tear can lead to a rougher ride and reduced handling performance. Regular inspections and replacing worn parts can help keep your FX35 riding smoothly.

Another common issue is problems with the power steering system. This can include leaks, pump failures, or other problems that can make it difficult to steer the car. Checking the power steering fluid levels regularly and having any leaks addressed promptly can help prevent more severe problems.

Other Potential Problems

There are a few other things to be aware of. Like many cars, the FX35 can develop issues with its air conditioning system. This can be caused by refrigerant leaks, compressor failures, or other problems. Regular maintenance, such as changing the cabin air filter, can help keep your AC system running smoothly. It is also important to remember that problems with the FX35 can vary from car to car.

Maintenance Tips for a Reliable FX35

Now that you know the common issues, here's how to keep your 2004 Infiniti FX35 running reliably. Doing proper maintenance is a huge step in keeping your car in good shape.

Regular Maintenance Schedule

Sticking to a regular maintenance schedule is the best thing you can do for your car. This means following the manufacturer's recommendations for things like oil changes, filter replacements, and other routine services. Check your owner's manual for the recommended schedule. Having a good service history can also make the car last much longer. Staying on top of routine maintenance can catch issues early, before they turn into expensive repairs.

Engine Care

Engine care is critical. As mentioned earlier, regularly check your oil levels and top them up as needed. Use high-quality oil and change it at the recommended intervals. Pay attention to any unusual engine noises, which could indicate a problem. Also, inspect your engine for leaks. Address any issues you find right away to prevent further damage. Regular tune-ups, including spark plug replacement, can also help keep your engine running smoothly. All this helps your engine last longer.

Transmission Care

Transmission care is another important point. Regularly change the transmission fluid according to the manufacturer's recommendations. Pay attention to any unusual shifting behavior, such as shuddering or slipping gears. If you notice any problems, have your transmission checked by a qualified mechanic immediately. Addressing transmission problems early can save you a lot of money in the long run.

Electrical System Checks

Keeping up with the electrical system is also vital. Inspect all your fuses and relays regularly. Check for any corrosion or damage to the wiring. If you experience any electrical issues, have them diagnosed and repaired promptly by a qualified mechanic. Electrical problems can be tricky, so it's best to have a professional handle them.

Suspension and Steering Maintenance

As part of routine maintenance, inspect your suspension and steering components regularly. Pay attention to any unusual noises or handling issues. Replace worn-out components, such as shocks, struts, and bushings, as needed. Keep your power steering fluid at the correct level and address any leaks promptly.

Should You Buy a 2004 Infiniti FX35?

So, is the 2004 Infiniti FX35 a good buy? It depends. If you're looking for a stylish, sporty SUV and don't mind the potential for some maintenance, it can be a great choice. You'll need to do your homework and be prepared to address the common problems we've discussed. However, if you are not prepared to do the maintenance, this car is not for you.

Before you buy, get a pre-purchase inspection from a trusted mechanic. This will help you identify any existing problems and give you a better idea of what you're getting into. Ask the seller for the service history. A well-maintained FX35 is much more likely to be reliable than one that has been neglected. Also, consider the price. The FX35 can be a good value compared to other luxury SUVs, but you need to factor in potential repair costs.
