I would send it to groovetickler (Joseph Long) for an assessment and repair if necessary. See his Instragram page; he’s posted hundreds (thousands?) of his repairs w/ pics and videos. Hopefully something simple like the coils got rotated.
Glider is a sweet cart. Hard to say if Benz is even in business anymore; nobody seems to have a direct line on that. Pretty sure the factory trade-ins are long gone but they were a great deal in the 2000s!
