BYD ATTO 3 rear indicator flashing rapidly: why the Japanese recall replaces the rear combination lamp

If an ATTO 3 rear indicator suddenly flashes rapidly or operates intermittently, do not assume the repair is simply a bulb replacement. A Japanese recall identifies an internal rear combination lamp problem. Checking the vehicle scope first makes inspection and ordering more specific.

Which Japanese vehicles are covered?

The market is Japan only. Gai-4134 (Japan MLIT foreign-vehicle recall no. Gai-4134) was filed on Feb 12, 2026, with the action starting on Feb 13. The original filing does not separately identify a model year; no public model-year data was available. [To be verified] It explicitly lists the following type, chassis range and import period.[Original filing][S07]

| Japanese type | Chassis range as listed in the notice | Import period | Quantity covered |
| --- | --- | --- | --- |
| ZAA-SC2EXSQ | LGXCE4CB1P2****** to LGXCE4CB9N2****** | 2022-12-29 to 2023-09-07 | 1,097 vehicles |

The range and sequence follow the original filing; do not rearrange them into different start and end numbers. The import period must not be restated as a production model year.

The fault sequence begins inside the lamp

The notice states that desiccant in some lamps was not attached in the correct position. After absorbing moisture and expanding, it may interfere with the circuit board, causing short circuits or open circuits and rapid, intermittent or absent rear indicator operation.[Defect description][S07]

An unlit lamp therefore does not establish a requirement for a universal bulb. Moisture alone does not establish a failed lamp housing seal either. Check the actual symptoms against the internal fault in this action, rather than trial-fitting a visually similar part.

The official measure replaces the affected rear combination lamps

The action requires affected rear combination lamps to be replaced with conforming parts.[Corrective measure][S07] Identifying the desiccant as the cause does not mean independently opening the lamp and moving it is a manufacturer-approved repair. When ordering, distinguish the rear combination lamp requirement from any separately diagnosed wiring issue.

Have abnormal indicator operation inspected promptly. For vehicles within the range, contact a Japanese BYD authorised dealer first to confirm applicability and whether the recall has been completed.

Verification and parts enquiries

This scope belongs only to the Japanese action and does not extend to other markets. No public data was available for specific OE numbers, cross-market lamp interchangeability or permission to repair an opened housing. [To be verified] Select parts using the VIN and local manufacturer parts catalogue, rather than appearance or connectors alone.

For separate lighting parts requirements, use the parts enquiry page.
