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.
13-187
THIS COMMUNICATION IS THE FINAL CUSTOMER NOTIFICATION FOR ADVISORY 13-187 FOR THE UNITS MANUFACTURED WITH THE CONTROL CENTER WIRED INCORRECTLY CAUSING THE 110 VOLT SYSTEM OF THE WATER HEATER NOT TO FUNCTION.
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.
