GM recalled 23,700 model year 2024 Equinox EV vehicles due to an incorrect software calibration in the pedestrian alert sound system. The vehicles do not produce a sufficient change in volume when accelerating from a stopped position to 10 km/h (6.2 mph), failing to meet FMVSS 141 Section 5.4 requirements. This means pedestrians and cyclists may not hear the approaching vehicle at low speeds, increasing the risk of pedestrian-vehicle incidents.
Common Symptoms
- Vehicle is unusually quiet when accelerating from a stop
- Pedestrians not reacting to vehicle approach at low speeds
- No change in exterior warning sound volume from 0-6 mph
- Recall notification letter received
- Pedestrian alert sound noticeably quieter than other EVs
How to Fix
Contact Chevrolet dealer for recall service. The fix requires a body control module (BCM) software update. The 2025 model year uses a different noise generation strategy that will likely be adapted for 2024 models. Contact Chevrolet at 1-800-222-1020 with recall number N252527170.
