If you do need any maintenance, it can be done at any dealer. Depending on the lease agreement, you can probably return the car to a different dealer as well. My first lease was a Spark EV and the first time it went back to a dealer (different dealer than the one I leased from) was to return it at 3 years. I'm nearing 2 years into the Bolt lease and it's long overdue for the battery monitoring recall. The one time I had an appointment for that their single EV tech was out for training that day, so it was a wasted trip. I'll try again and have them do a tire rotation while they're at it.
