2025—2026 EX5 cornering deceleration: distinguish ICC software from brake hardware

If deceleration through bends with ICC feels different, a workshop visit may begin with a request to inspect or replace brake parts. For Australian MY25—26 EX5 Complete/Inspire, explaining software changes and whether ICC was active gives diagnosis a more precise starting point.

The factory recorded a specific refinement

Geely Australia's Flyme Auto 1.3.0 update notice describes smoother deceleration through bends with ICC enabled and fewer corrections. The original lists a release date of Oct 12, 2026.[Factory update][P03]

This describes control refinement in a specific driver-assistance situation. It does not require replacement of brake discs, pads or a control module, or define a particular deceleration feel as a hardware fault. That software background helps the repairer distinguish changed function behaviour from a separate issue needing diagnosis.

State whether ICC was operating

“Braking feels jerky” can merge different situations. More useful records state whether ICC was enabled, whether deceleration occurred entering a bend, within it or elsewhere, any instrument message and the actual vehicle software status.

Describe any separate abnormalities during pedal braking independently. A factory ICC refinement does not make every brake complaint the same software issue. Equally, one assisted-deceleration experience does not directly establish that a mechanical part needs replacement.

Check software background before choosing a purchasing component

Use the vehicle and local service records to establish whether it has been updated, whether it is eligible and which version is installed. Hearing that a similar vehicle received an update does not establish completion of the same action on this vehicle.

The notice offers an intake clue but no brake hardware test limits. A purchasing list should follow diagnosis identifying a specific component. A version number does not justify replacing brake parts.

Scope and verification

This article covers only Australian MY25 and MY26 EX5 Complete/Inspire. The 1.3.0 original says all EX5, while another factory update explicitly identifies these model years and trims. This article uses their overlap and does not extend to MY27 or other versions.[Model-year basis][P04]

This is a historical software update notice, not a recall. It does not establish installation on every vehicle or that 1.3.0 remains the latest version. No public data was available for the current vehicle's applicable update, ICC target deceleration, hardware diagnosis/calibration and replacement criteria, OE numbers, separate supply or interchangeability. [To be verified] Verify compatibility or interchangeability using the VIN and local Australian manufacturer parts catalogue.

For brake or driver-assistance parts identified after diagnosis, use the parts enquiry page.
