How much should it cost to replace the engine in a 2017 Honda Fit?

How many miles? And how did this happen? These vehicles have 5 year / 60,000 mile powertrain warranties - and often times Honda dealerships can offer additional assistance depending on the scenario. Tell me more about what happened and the situation. It sounds quite abnormal to be honest. This doesn't happen under normal circumstances. To answer the question you asked, you'll have to get quotes local to you. There are several ways to go, if no warranty applies, perhaps a used engine would be the best idea. Otherwise, new Honda components will run north of $10,000.
