Recalls

8 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Seat belts, Airbags Vehicle recall #21V230000 · 2021 · 8,634 vehicles

What's wrong: Please refer to mbusa's recall report for specific vehicle model details. A faulty electrical contact within the seat position switch May prevent the driver and passenger air bags and seat belt force limiters from properly activating during a crash.

Why it matters: Air bags and seat belts that do not perform properly in a crash can increase the risk of injury.

The fix: Mbusa will notify owners, and dealers will replace the seat position switches, free of charge. Owner letters were mailed May 21, 2021.

Latches & locks Vehicle recall #21V353000 · 2021 · 17,800 vehicles

What's wrong: Components within the door latch May prevent the rear doors from latching or opening properly.

Why it matters: The rear door May appear closed even when the latch is not fully engaged, allowing the door to open while driving and increasing the risk of injury or a crash. Damaged latch components May prevent the rear door from being opened while inside the vehicle, increasing the risk of injury.

The fix: Dealers will replace the rear door latches, free of charge. Owner notification letters were mailed July 9, 2021.

Seat belts Vehicle recall #21V483000 · 2021 · 4,917 vehicles

What's wrong: The rear seat belt automatic locking retractors May deactivate early, which can prevent the child restraint system from securing properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "occupant crash protection."

Why it matters: An unsecured child restraint system can increase the risk of injury during a crash.

The fix: Dealers will inspect, and replace as necessary, the rear seat belt assemblies, free of charge. Owners notified of the voluntary recall campaign by an interim letter on August 13, 2021. A final letter was mailed on September 24, 2021.

Airbags Vehicle recall #21V527000 · 2021 · 542 vehicles

What's wrong: The side crash sensor connectors May come loose, which could delay the activation of air bags and seatbelts during a side impact crash.

Why it matters: Air bags and seatbelts that don't function as intended can increase the risk of injury during a crash.

The fix: Dealers will inspect and replace as necessary, the side impact crash sensors, free of charge. Owner notification letters were mailed on September 3, 2021.

Communication, Electrical Vehicle recall #22V365000 · 2022 · 242,722 vehicles

What's wrong: Please refer to mbusa's recall report for specific vehicle model details. An error in the communication module's sim card software can cause a mobile network connection failure, disabling the emergency call (ecall) system.

Why it matters: A disabled ecall system would prevent a vehicle occupant from contacting the emergency services call center in an emergency, potentially delaying emergency responders and increasing the risk of injury.

The fix: The communication module software will be updated through an over-the-air (ota) update or by a dealer, free of charge. Owner notification letters were mailed July 8, 2022. Owner notification letters will be mailed in phases, on July 8, 2022, May 17, 2024, July 29, 2024, and September 27, 2024.

Electrical Vehicle recall #23V097000 · 2023 · 26,116 vehicles

What's wrong: The front axle wiring harness May chafe against an oil cooler and become damaged, which can cause a loss of anti-lock brakes (ABS) and electronic stability control (esc).

Why it matters: A loss of anti-lock brakes or electronic stability control can increase the risk of a crash.

The fix: Dealers will inspect and either install a protective sleeve or replace the front axle wiring harness, as necessary, free of charge. Owner notification letters were mailed April 10, 2023.

Fuel system Vehicle recall #23V445000 · 2023 · 143,551 vehicles

What's wrong: Please refer to mbusa's recall report for specific vehicle details. The fuel pump May shutdown, which can result in a loss of drive power.

Why it matters: A loss of drive power can increase the risk of a crash.

The fix: Dealers will replace the fuel pump, free of charge. Owner notification letters were mailed on June 14, 2024.

Latches & locks Vehicle recall #24V659000 · 2024 · 134 vehicles

What's wrong: Components within the right-side rear door latch May prevent the rear doors from latching or opening properly.

Why it matters: The rear door May appear closed even when the latch is not fully engaged, allowing the door to open while driving and increasing the risk of injury or a crash. Damaged latch components May prevent the rear door from being opened while inside the vehicle, increasing the risk of injury.

The fix: Dealers will replace the right-side rear door latches, free of charge. Owner notification letters were mailed October 11, 2024.
