They don't seem to want to sell EVs though. Until people start driving them and demanding them, they don't have much incentive to set up a strong service network.Your points are valid, though I think it would also be fair to assume that a manufacturer, of any type of customer object, should be prepared to service any specific needs of that item once it hits the market. Buying a Bolt does not come with a disclaimer that service windows will be longer due to lack of knowledge of the vehicle throughout dealer networks. In theory, prior to release of a new item, the manufacturer should be prepared to provide reliable service to its clients. I also think that, depending on the dealership, there will be significant differences in the ability to service EVs, as has been displayed on this forum. Unfortunately the dealership closest to my home seems, according to reports I've seen and interaction with other customers, ill-prepared to service any type of vehicle, let alone EVs.
I should nuance that my experience with other manufacturers hasn't all been related to warranty repairs. I never had a problem with my BMW (bought new and under warranty) or Audi (bought used and out of warranty) and had to do limited repairs on my 2006 Cayman S (bought used and out of warranty) which, at 13 years old, understandably has required a couple "wear and tear" interventions (replaced starter, replaced battery). That said, these experiences have been sufficient to develop an impression of each dealer network and the experience that was offered.
