What's wrong?
The power liftgate on the 2020-2021 Mazda CX-30 uses drive units and support springs to raise the rear hatch and hold it fully open. The drive unit is the motorized slider that moves the liftgate, while the spring support helps carry the weight so the hatch stays up when the vehicle is parked.
On affected CX-30s, certain power liftgate drive units do not have enough frictional retaining force to hold the liftgate at the top of its travel. In high ambient temperatures, the support spring force also drops. When the vehicle is facing uphill on a slope, those forces combine and the fully opened liftgate can slowly lower from its open position.
There is no warning sign before failure. Owners are not given a light, chime, message, or other indication before the liftgate begins to lower.

What's the safety risk?
The power liftgate can lower unexpectedly while someone is using the rear storage area, increasing the risk of injury. There is no warning sign before this happens. Keep people clear of the liftgate path, use extra care around the rear opening, and schedule the dealer software update and inspection soon. Repair is free at any franchised Mazda dealer.
What should I do?
- Check your VIN to confirm your 2020-2021 Mazda CX-30 is included in this recall.
- Contact a franchised Mazda dealer to schedule the free power-liftgate software update, drive-unit serial-number inspection, and replacement if needed for the liftgate lowering while parked uphill.
- Bring the recall notice if Mazda mailed one. If not, reference recall number 21V086 when you call.
- Keep people clear of the rear storage opening when the CX-30 is parked uphill until the repair is complete.
- Call Mazda customer service at 1-800-222-5500 with questions about scheduling or dealer instructions.
What happens at the repair
At the dealer, a Mazda technician updates the power liftgate control module software and checks the serial number on the power liftgate drive unit. If the drive unit is covered by the recall and needs replacement, the technician replaces it. Parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing new vehicle warranty, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
