Good question. Honda makes no bones about working to produce their own platform. I did talk about that with the folks at the dealership, including the manager of the service department. While they will be moving on, they seem to feel very strongly that the Ultium is a very good product and they have been training their technicians to work with it. The service manager also pointed out that the “auto group” he works with also has a Chevy (and other) dealership, and they confer with each other. I came away feeling good about their support for this EV.
but this issue is another reason to consider leasing the Prologue and having the flexibility to move to a newer platform in the near future.
