I lifted the seat up and smoke was coming from the controller and/or solenoid. I removed the seat and flames started shooting from the controller.
I need some help understanding what happened and which part failed. I suspect the motor went first due to the noise and real wheels locking up. But I am unclear how that caused the controller to catch on fire. Even more puzzling, the fuse never blew...it is still intact.

Glad to hear you and yours got off the cart safely.
Except for the fire, I had close to the same thing happen. Motor (Stock PDS) made a noise, then seized and I slid to a stop. Sparks and smoke were coming out of the controller (DCX400), but arcing sounds stopped when I flipped the Run/Tow to Tow. The fuse (ANN250) did not blow.
Controllers have a bad habit of self-destructing when a motor fails while operating because all the outputs are shorted together when the motor fails.
I've assumed my motor failure was a combination of heat and RPM and regen braking stresses, because my motor was hot from being driven hard, it was spinning at about 8k and the failure occurred when I lifted my foot and the regen braking kicked in. But your motor failure could have been from heat alone, or maybe a brush broke, staring a chain reaction.
Again, glad you guys are okay.
