Common Infiniti I35 Problems and How to Fix Them

Alright, guys, let's talk about some of the issues you might face with your Infiniti I35. We're going to break down some of the most common problems and offer solutions. Remember, proper maintenance is key to keeping your I35 running smoothly. Don't worry, this isn't rocket science, and with a little know-how, you can often handle these issues yourself.

1. Engine Issues: The Heart of the Matter

The engine is the heart of your car, and when it stumbles, it can be a real headache. One common issue with the Infiniti I35 is the potential for engine oil consumption. Some owners have reported that their engines burn through oil faster than normal. This can lead to decreased engine performance and potential damage if the oil level gets too low. Another trouble spot can be the ignition coils. These coils are responsible for igniting the fuel in the engine cylinders. Over time, they can wear out, causing misfires and rough engine running. Additionally, the Mass Air Flow (MAF) sensor can cause problems. This sensor measures the amount of air entering the engine, and if it fails, it can lead to poor fuel economy and performance.

Solutions:

• Oil Consumption: Regularly check your oil level and top it off as needed. Consider using a thicker viscosity oil, especially if your car has high mileage. If the consumption is excessive, you may need to consult with a mechanic to check for internal engine issues.
• Ignition Coils: If you suspect faulty ignition coils, have them tested or visually inspected. If the coils are bad, replacing them is usually a straightforward fix. This will often resolve misfires and improve engine performance.
• MAF Sensor: If the MAF sensor is faulty, you may notice the check engine light come on. Cleaning or replacing the MAF sensor can often resolve issues related to poor fuel economy and performance. Use a specialized MAF cleaner, and ensure it's properly installed.

2. Transmission Troubles: Smooth Shifts

The transmission is responsible for transferring power from the engine to the wheels. The Infiniti I35 can experience some transmission-related issues, primarily with the automatic transmission. Some owners have reported hard shifting, slipping, or complete failure. These issues can be caused by various factors, including low transmission fluid, worn-out internal components, or valve body issues. These transmission problems can make driving feel clunky and unpredictable.

Solutions:

• Transmission Fluid: Regularly check your transmission fluid level and condition. Change the fluid as recommended in your owner's manual. Using the correct type of transmission fluid is crucial.
• Transmission Problems: For more serious transmission issues, it's best to consult with a qualified mechanic. They can diagnose the problem and recommend the appropriate repairs, which might include replacing internal parts or rebuilding the transmission.

3. Electrical Gremlins: The Electronic Woes

Electrical issues can be frustrating because they can be difficult to diagnose. The Infiniti I35 can sometimes experience problems with its electrical system. Some common electrical issues include problems with the power windows, door locks, and the infotainment system. These issues can stem from a variety of sources, including faulty wiring, bad relays, or malfunctioning control modules. These electrical problems can cause inconvenience and affect the overall functionality of the car.

Solutions:

• Power Windows and Door Locks: Check the fuses and relays related to the power windows and door locks. If a fuse is blown, replace it. If a relay is faulty, replace it as well. Also, inspect the wiring for any damage.
• Infotainment System: If the infotainment system isn't working correctly, check the connections and fuses. Sometimes, a simple reset can resolve the issue. If the problem persists, consult with a mechanic or specialist to diagnose the problem.

4. Suspension & Steering: Riding Smoothly

The suspension and steering systems contribute to your car's ride quality and handling. The Infiniti I35 may experience some issues related to these systems. Common problems include worn-out shocks and struts, which can lead to a bouncy ride or poor handling. Suspension bushings can also wear out over time, causing clunking noises and affecting the ride quality. Steering issues may involve power steering pump failure or leaks.

Solutions:

• Shocks and Struts: If your car is riding rough or bouncy, have your shocks and struts inspected. Replacing them can significantly improve your car's ride quality and handling. Typically, this is a straightforward repair.
• Suspension Bushings: If you hear clunking noises, it may be time to replace your suspension bushings. A mechanic can assess the condition of your bushings and recommend the necessary repairs. Properly functioning bushings are crucial for a smooth ride.
• Steering Issues: If you experience steering problems, such as a stiff steering wheel or fluid leaks, have your power steering system inspected. Addressing any leaks or pump failures promptly can prevent further damage.

5. Other Potential Issues

Beyond the issues, the Infiniti I35 owners have reported, there are some other things to keep in mind. Problems with the air conditioning system, such as compressor failure, can lead to inadequate cooling. Also, the catalytic converters can fail over time, potentially impacting engine performance and emissions. Lastly, the car's interior features, such as the seats or the dashboard, might show signs of wear and tear, depending on use and maintenance.

Solutions:

• Air Conditioning: If your AC isn't cooling properly, have it inspected by a professional. This may involve checking the refrigerant level, the compressor, and other components.
• Catalytic Converter: If you suspect a problem with your catalytic converter, have it tested. Replacing the converter may be necessary if it's not functioning correctly.
• Interior: Depending on the interior's condition, you may consider repairing or replacing worn parts like seats or dashboards.
