Dean,
Thank you for using the Answer Army to post your questions.
This is not a known issue concerning these units, and is not only preventable but should never have been happening in the first place. I would highly recommend that you have this unit evaluated by an authorized servicing dealer to try and figure out what is happening here. Likely the dealer from which you had purchased this unit would be able to offer service on the unit, however if for whatever reason they are not able to use the link below to find a dealer in your area:

Thanks again.
