Common Problems with the 2004 Infiniti G35 Automatic Coupe

The 2004 Infiniti G35 automatic coupe is a stylish ride, but it's not without its faults. Let's break down some of the most frequently reported issues. Understanding these can help you anticipate potential problems and keep your G35 running smoothly.

Engine Issues

When it comes to the 2004 Infiniti G35 automatic coupe, engine problems are something to keep an eye on. Some owners have reported issues such as excessive oil consumption.

Using the correct fuel grade, as recommended by Infiniti, can often resolve minor knocking issues. However, if the knocking persists, it's crucial to have a mechanic diagnose the root cause. Ignoring engine knocking can lead to severe engine damage, which can be incredibly costly to repair. Regular maintenance and addressing small issues early are key to ensuring the longevity and reliability of your G35's engine. Addressing these engine issues promptly can significantly extend the life of your G35 and keep it performing at its best.

Transmission Issues

Transmission problems can also be a concern for owners of the 2004 Infiniti G35 automatic coupe. Some drivers have reported experiencing rough shifting, especially between gears. This can manifest as a noticeable jerk or hesitation during acceleration. In some cases, the transmission might even slip out of gear, which is not only annoying but also potentially dangerous. If you notice any unusual behavior from your transmission, it's important to get it checked out by a professional as soon as possible. Ignoring these symptoms can lead to more significant damage and costly repairs.

Another common issue is related to the transmission's solenoids. These solenoids control the flow of transmission fluid and are crucial for smooth gear changes.

Replacing the solenoids can often resolve these issues, but it's a job best left to experienced mechanics. Regular maintenance, such as fluid changes and inspections, can help prevent solenoid problems and extend the life of your transmission. Be vigilant for any signs of trouble, such as slipping gears or harsh shifting, and address them promptly to avoid more extensive damage.

Furthermore, keep an eye out for any leaks coming from the transmission. Transmission fluid is essential for lubricating the internal components and maintaining proper pressure. Leaks can lead to low fluid levels, which can cause the transmission to overheat and eventually fail. Regularly inspect the area around the transmission for any signs of leaks, such as puddles of red fluid. If you notice any leaks, have them repaired immediately to prevent further damage. Regular maintenance, including fluid and filter changes, is crucial for keeping your transmission in good working order and preventing costly repairs.

Electrical Issues

Don't overlook the electrical gremlins that can plague the 2004 Infiniti G35 automatic coupe. One of the most common complaints revolves around the car's electrical system.
