2021 ENTEGRA ESTEEM Electrical System Problems

Service Advance Trac System warning light illuminated while driving about 60 MPH in gusty wind. Cruise Control and Hill Assist became inop. This happened twice on one 500 mile trip, both times in windy conditions. Both times, after shutting off engine for a few minutes, no warning light and all systems functioned normally again. Reading motorhome forums, this seems to be a common problem with Ford E Series and F53 chassis motorhomes of various brands. I haven't read any conclusive fix for the problem. I do see that Ford has a service bulletin, SSM 49349 which describes this exact problem and states that Ford "...engineering is working to implement a solution for this condition...", and advises that the dealer "...schedule a follow-up appointment for service in March 2021". I have not found any additional information from Ford about a fix for the problem....now 3.5 years later.

The RV had been driven about 20,000 miles and had about 250 accumulated hours on the onboard ONAN 4000 generator. I performed an oil change and did a test run of the generator when I happened to notice major generator tail pipe movement particularly during the start operation but which also continued during normal run operations. So I began to investigate and discovered that the tail pipe suspension mount nearest the exhaust point had become separated from the body of the coach but was still attached to the exhaust pipe. The mount was attached with a single bolt into a blind hole in the body panel. The mount had a very long perforated steel blade which was fastened to the body at only one low location. When the mount became dislodged, the steel blade was moving around significantly causing major abrasion to the generator electrical power line. On further observation,...
