What Problems Does the 2006 Infiniti M35 Have?
The 2006 Infiniti M35, while generally reliable, is not without its specific quirks and common issues that owners frequently report. One of the most widespread problems is an inaccurate or failing fuel level sender unit, which can cause the fuel gauge to read incorrectly, sometimes showing a full tank when nearly empty or vice-versa. This is a common and frustrating issue for this model year and across the VQ platform.
Another frequently cited problem involves the HVAC system, specifically failures of the blower motor, blower motor resistor, or the AC amplifier. These can lead to erratic fan speeds, a non-functioning fan, or complete loss of climate control.
Aging M35s may also experience oil leaks from valve cover gaskets, a common wear item on many VQ engines. Suspension components, such as control arm bushings and sway bar links, are known to wear out, leading to clunking noises, a less precise ride, or premature tire wear. Power window motors can also fail over time, requiring replacement.
Regarding recalls, the 2006 Infiniti M35 was part of a significant recall concerning the passenger front airbag occupant classification system (OCSM). A faulty sensor could cause the passenger airbag to deactivate, increasing the risk of injury in a crash. Owners should verify this recall has been addressed. Another recall involved a potentially faulty brake light switch, which could cause brake lights to illuminate inconsistently or not at all.
In terms of long-term reliability, the M35's VQ35DE engine and automatic transmission are generally robust and capable of high mileage with proper maintenance. However, the accumulation of these common electrical and wear-item issues means that while the core powertrain is strong, owners should anticipate addressing these specific problems as the vehicle ages. Diligent maintenance, including regular fluid changes and prompt attention to warning signs, is crucial for extended trouble-free ownership.
