Common 2012 Infiniti Ex35 problems
The Infiniti EX35, produced between 2008 and 2012, has been known to have certain common issues that owners have reported. These issues span across various components, including the engine, transmission, electrical system, and suspension.
One of the most reported engine-related issues in the Infiniti EX35 is fuel pump failure. The fuel pump is responsible for delivering fuel from the tank to the engine, and when it fails, the vehicle may experience engine stalling, hesitation, or difficulty starting.

In addition to fuel pump issues, some owners have reported transmission problems with the EX35. The transmission may shift roughly or slip, particularly when shifting between first and second gear. This issue can be caused by low transmission fluid levels, worn transmission components, or internal transmission problems.
The electrical system in the EX35 has also been reported to have issues. Some owners have reported that the battery drains quickly, even when the vehicle is not in use. This issue can be caused by a malfunctioning battery, a faulty alternator, or a parasitic draw on the electrical system. Additionally, some owners have reported that the dashboard lights flicker or fail to illuminate properly, which can make it difficult to monitor the vehicle's performance.
Suspension and steering issues have also been reported in the EX35. Some owners have reported problems with the power steering system, such as fluid leaks or failure of the power steering pump. Other owners have reported issues with the suspension, including noisy shocks or struts and worn suspension components. These issues can affect the vehicle's handling and ride quality, making it uncomfortable to drive.
