Went into the shop today and they hooked our Crew up to see if any updates were available. No flash updates showed as available for the 2011 Journey but upon searching the technician found a fix. The fix was listed as a flash update to repair EVIC with garbled and or scrambled text. A service bulletin was issued for the EVIC but it does not have anything about fixing the MPH to KPH issue. After powering the vehicle on/off several times it seems the issue is now resolved.
Keep up the good work guys.
