What's involved

What this repair actually is.

Most hybrids cool the battery pack with a fan that pulls cabin air through vents, and over time the fan and vents clog with dust, pet hair and debris. We remove the fan assembly, clean or replace the fan and filter, and clear the ducts so the pack runs at safe temperatures.

Symptoms

How you can tell.

  • Whirring or grinding fan noise behind the rear seat
  • Battery or hybrid warning on hot days
  • Fuel economy drops in summer
  • Musty smell from the rear vents
  • Visible dust buildup around the battery vents
If you delay

A clogged cooling fan overheats the battery pack, which shortens its life dramatically and can trigger hybrid system faults.
