NHTSA Complaint #11547715 — 2016 FORD C-MAX

Was driving it to a shop to do a transmission fluid exchange and got a big Stop Safely Now warning on the dash with an AdvanceTrac warning as well. Car stopped dead on a freeway off ramp - was very fortunate to get an immediate SoCal Freeway Service tow off the ramp in Los Angeles to a safe place, and after AAA told me I might wait 4 hours for a tow to my preferred Ford dealer, I got the car restarted and got it to a another dealer a couple miles away. Inspection showed a P0B37 error code with chafing of the high voltage battery harness. The dealer originally quoted me $1200 to fix it, but when I mentioned the California 10/150 hybrid powertrain warranty, they subsequently found TSB 17-0015 which deals with this exact issue on the 2013-16 Energi, and I've now read a report of the same issue on a 2017. The TSB quotes 1.8 hours labor with chafing and installation of heat shrink tubing, tie strap, and electrical tape... where the dealer came up with $1200 is beyond me. Obviously I'm pleased with the fact Ford is covering this one, but hope it doesn't happen to you... I had about 30 seconds to get the car to a safe place before it stopped entirely, and if I'd been in heavier traffic the vehicle would have stopped dead on a very busy expressway.
