Chevrolet Equinox EV 2024–2027 rear brake noise: what GM says in PIC6656A

Owners of the Chevrolet Equinox EV may hear noise from the rear brakes specifically while reversing, but GM is not recommending that pads be replaced blindly. The company is investigating the cause and has issued preliminary service information PIC6656A covering 2024–2027 Equinox EV models in North America.

According to the document, the sound may be more noticeable in cold or wet weather. The cause is currently listed as undetermined, and there is no approved repair or parts-replacement procedure yet. GM engineers are continuing the investigation. Once the source is identified, the preliminary information is expected to be updated or replaced by a full technical bulletin.

This is not a recall. GM says the vehicle may continue to be driven if the described noise occurs. The information applies to all VINs and configurations of the specified Equinox EV model years in the North American market, but that does not mean every vehicle will develop the noise.

The main issue for now is not a confirmed safety risk but the lack of a final answer: GM has acknowledged the complaints and is investigating them, while the cause of the noise and an approved repair had not yet been determined as of September 25, 2026.
