On the 2008-2012 Infiniti EX35, the EX35 shares the sunroof drain architecture of its G-platform siblings: a tray around the glass panel that collects water and routes it through tubes down the A- and C-pillars. Debris packs the drain nipples at the tray corners, the tray overflows, and water enters the headliner and runs down the pillars into the cabin. Owners find soaked footwell carpet, water dripping from the headliner or map light, and a persistent musty smell. Because the water tracks past wiring and body modules on its way down, the complaint frequently presents as unexplained electrical behavior before anyone notices the carpet is wet. On a hatchback like the EX35 the rear cargo area and the spare tire well are also common places to find standing water.

Common Symptoms

  • Wet or damp footwell or cargo area carpet
  • Water dripping from the headliner or map light
  • Standing water in the spare tire well
  • Persistent musty or mildew smell
  • Unexplained electrical faults or erratic module behavior
  • Interior glass fogging that will not clear

How to Fix

Open the sunroof and locate the drain openings at the four corners of the tray. Clear them with low-pressure compressed air or soft weed-trimmer line worked in gently. Never use a stiff wire or drain snake — it punches through the tube inside the pillar and converts a clogged drain into a permanent leak that is much harder to fix. Pour a little water into the tray and confirm it exits behind each wheel. Lift the carpet and padding to dry them completely rather than letting them dry in place, since trapped moisture corrodes connectors and modules under the seats. Check the spare tire well and the tailgate seal as well, both of which collect water on this body. Resolve the leak before diagnosing any electrical fault on a car with damp carpet.

On the 2008-2012 Infiniti EX35, the VQ35HR engine in the EX35 exhibits higher-than-normal oil consumption, typically burning 1 quart every 2,000-3,000 miles. Worn valve stem seals and piston ring coking contribute to the problem, especially in vehicles with infrequent oil changes.

This issue also affects: Infiniti FX35, Infiniti G37, Nissan 350Z

Common Symptoms

  • Oil level dropping between changes
  • Light blue exhaust smoke on startup
  • Fouled spark plugs

How to Fix

Perform an oil consumption test at the dealer to establish baseline usage. Replace valve stem seals if consumption exceeds 1 quart per 1,500 miles. Use quality 5W-30 synthetic oil and change every 5,000 miles.
