Vehicle report
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.
1ST-TSB198-83123
Airstream has found that some Basecamps with the Suburban IW60 water heater, which have been upgraded to Lithium batteries, may experience a failure in the water heater firing, due to spikes in voltage.
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.
