TRAILER HITCHES
Mazda North American Operations (Mazda) is recalling certain 2024-2025 CX-50 vehicles equipped with Mazda Genuine Accessory trailer hitches. The trailer hitch assembly bolts may loosen and cause the assembly to separate from the vehicle body during towing or normal driving conditions.
LANE DEPARTURE: SENSING SYSTEM: CAMERA

2025 CX-50 Hybrid models can display a 'Hybrid System Failure' message on the instrument meter with the engine failing to start. Mazda traced this to improper logic in the Powertrain Gateway Unit (PT-GWU). The TSB applies to 2025 CX-50 Hybrids built before April 22, 2025 (VIN bel… Severity: high.
2024-2025 CX-50 vehicles fitted with the Mazda Genuine Accessory trailer hitch may have mounting bolts that were not sufficiently tightened during installation. The bolts can loosen and the hitch assembly can separate from the body during towing or normal driving, creating a road… Severity: high.
On roughly 1,007 MY2025 CX-50 and CX-50 Hybrid units built at Mazda Toyota Manufacturing in Huntsville, AL, front suspension fasteners — notably the bolt clamping the lower control arm ball joint into the steering knuckle — were not tightened to specification on the assembly line… Repairs typically run $0-$0. Severity: high.
Certain 2025 CX-50 Hybrid units left the plant with the powertrain control software still in the factory/transport configuration.

CX-50 owners report the i-Activsense Smart Brake Support system applying the brakes hard with no obstacle present — most often when a lead vehicle turns off the road, when cornering past guardrails or metal roadside barriers, in stop-and-go traffic, and when passing reflective su… Repairs typically run $0-$250. Severity: high.
CX-50 owners get to the pump and the fuel door will not release: the release button does nothing, and the door cannot be pried open by hand.

CX-50 owners report windshields that crack with little or no impact, with cracks often originating at the driver-side A-pillar or progressing rapidly from a minor pebble star into a full-length crack — a pattern attributed to stress fracturing rather than impact damage. Warranty… Severity: medium.

The outside air temperature sensor mounted behind the front bumper fascia can drift or fail low, displaying a cluster temperature as much as 50°F below actual.

The Mazda Connect infotainment system in the CX-50 suffers from slow response to commander control inputs, delayed map rendering, and laggy menu transitions. The system processor struggles with modern navigation demands and simultaneous Bluetooth/CarPlay tasks. Firmware updates h… Repairs typically run $0-$800. Severity: low.
