It can be a problem from usually low voltage issues and trying to run the system. If you only have two motors you can re-sync and set them. Do you have your owners manuals? If you have the three or four motor system a teach pendant is needed to reset the timing and stops of the system. This would require you to take it to a repair facility that has this equipment. We don't see a lot of problems with Power Gear if it is operated properly with the engine running and good batteries in the coach.
