I apologize if this has been addressed before, but I couldn’t find any similar stories- a couple of days ago I was driving on the highway (2019 PP) and the dashboard lit up, saying “All Wheel Drive System Problem”. Since it was Sunday, I got off the highway and took the back roads. Went to the dealership yesterday to drop it off. (The warning was not there when I restarted the PP in the morning.) Got a call a couple of hours later, I was told the entire rear diff would have to be replaced! There is a sensor that lets you know if the diff is running hot. This sensor currently can’t be replaced, so the fix is to replace the entire differential! This is mind boggling to me. The service manager just shrugged his shoulders and said that was what Honda recommended. It’s not going to cost me a penny but it seems like an incredible waste!
