What's wrong?
The wheel alignment on the 2022 Micro Bird G5 Transit Bus sets the angle of the wheels so the bus tracks straight and the tires meet the road correctly. The alignment ring is part of that setup. Its job is to help hold the wheel alignment at the intended angle after the alignment work is completed.
On the affected bus, the alignment ring was installed at the wrong angle during wheel alignment. That puts the wheel geometry out of position instead of locking it into the correct setting. As the bus is driven, the wheels can become misaligned, which affects how the vehicle tracks and how the tires contact the road.
There is no warning sign before failure. An owner or driver should not wait for a dashboard light or a clear steering symptom before arranging the recall repair.
