Welcome to the router forums.
I'm sorry to hear of your trouble with Bosch. I don't think that, salespersons are fully knowledgeable when it comes down to "known" or "unknown" issues with their products. This would and will fall into their service technicians department. There are many members here who have Bosch routers and haven't had trouble with them.

That is HONOR, and there are way too many people in this country who no longer understand it." -Author Unknown
