Engine oil service reference
Use the Honda-specified engine oil quantity for GM4 Hybrid: approximately 3.1 L oil-only or 3.3 L with filter.
Recalls & safety campaigns
Campaigns shown here have been manually mapped to this model code from manufacturer records.
Brake operating simulator improvement measure
Honda reported that assembly oil could enter the pressure sensor in the electric-servo brake operating simulator because of an improper manufacturing process.
Corrosion in the sensor can produce an abnormal output, illuminate a warning light and trigger fail-safe operation, increasing the brake-pedal force required.
Inspect the brake operating simulator pressure-sensor output; replace the simulator with the countermeasure part when it falls outside the inspection standard.
Honda lists Grace GM4 chassis GM4-1206609–GM4-1214803 and GM4-5200024–GM4-5200039 in improvement measure 661. Confirm the individual chassis with Honda before assuming applicability.

Component-family relationship graph
CarFactBook groups normalized component keys across exact chassis codes, then keeps the relationship evidence level explicit. A shared specification is not treated as fitment approval or interchangeability. Manufacturer-backed relationships can still be engine, grade or production-condition specific.
The exact vehicles share the same normalized documented specification key. This is evidence of a shared specification only.
Not fitment approval or interchangeability. Confirm the exact part, equipment, dimensions and production conditions before purchase.Both sides carry manufacturer-backed cross-reference evidence for the same component key.
This is stronger than a shared specification, but production period, equipment and any stated fitment conditions still control.Both sides explicitly carry CarFactBook-reviewed interchangeable evidence for this component relationship.
Use the exact reviewed relationship and its conditions. Do not generalize interchangeability to sibling chassis codes or other assemblies.Why L2 · Manufacturer cross-reference
