Service bulletins

1 bulletin

Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

Service Bulletin/Repair Instructions

BMPro made an unintentional change to their programming at some point in MY2026 that affects the generator functions while the ignition is on. Currently the AGS and START GENERATOR buttons are grayed out while the ignition is on. The generator can be started with the ignition off and then it will stay running when the ignition is turned on. It just can’t be started with the ignition already on. The AGS automatically disables, if it’s already enabled, when the ignition is turned on as a code requirement. However, with the current programming, it can’t be reenabled once the ignition is on.

Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
