2025 JAECOO J7 power loss: the ECU harness recall beside the engine bracket

If a New Zealand 2025 model-year JAECOO J7 T1EJ 1.6T suddenly loses power while driving, inspection should extend beyond the ECU itself. The RCB-2601 recall for this version concerns friction damage to the ECU harness beside the engine mounting bracket. Identifying the affected location helps avoid ordering a controller before checking its wiring.

Chafing beside the bracket can lead to engine shutdown

The NZTA public record states that a manufacturing defect may allow the ECU harness to rub against the engine mounting bracket and become damaged, potentially causing loss of power or engine shutdown without warning. [Recall defect explanation][N01J]

Loss of power is the symptom; the notice's inspection subject is the harness-to-bracket contact point. The ECU, its connected harness and the bracket are different items. ECU-harness damage should not be shortened to ECU failure and then used to justify an assembly replacement.

Record the contact location as well as wear

Inspection records for this recall should identify the harness section, where it contacts the bracket and the nature of the damage. A general statement that the wiring was repaired omits the key question: whether the contact condition causing wear was addressed to factory requirements.

This is not an invitation to reroute the whole harness based on experience alone. Because the notice identifies the rubbing components, the repair findings should address both harness damage and its contact cause. Surface wrapping alone cannot establish completion of the recall.

The notice does not determine which assembly must be replaced

The public remedy is to arrange inspection and repair at the local distributor. It does not publish a requirement for universal ECU or engine-bracket replacement. [Remedy explanation][N01J]

Parts ordering should follow the specific inspection and factory remedy. Mention of a bracket does not prove a structural bracket defect. Failure to find an independent harness part number also does not establish that a controller assembly is the only replacement option.

After a power interruption, first ensure the safety of people and the vehicle and contact the repairer to arrange inspection. Do not deliberately drive to reproduce it. An affected vehicle without symptoms also cannot substitute current normal operation for recall treatment.

Recall scope and verification

• Market: New Zealand only.
• Model year and configuration: The original record explicitly states MY25 and identifies JAECOO J7 T1EJ 1.6T. It is not extended to SHS/PHEV or other markets.
• Recall identifier: RCB-2601. The public database record was created on Feb 2, 2026; this is not a production period or first-publication date.
• Production period and VIN scope: Not listed in the original record; no public data were available. [To be verified] MY25 does not mean every vehicle is affected.

No public data were available in the reviewed material for harness OE numbers, separate supply, specified routing, fastener and bracket replacement requirements, test values or ECU replacement conditions. [To be verified] The local brand distributor must verify each vehicle's recall status. Compatibility or interchangeability must be checked using the VIN and New Zealand local factory parts catalogue. This article does not cover the under-seat harness recall or borrow Australia's VIN list.
