I hear a lot about the various EVs on the market and their drivetrain/software/ride quality but I rarely hear about the quality of service that comes post-purchase. Perhaps because it’s not an exciting topic.
Which brand would y’all say has the best or worst reputation in the regard? How would you say Chevy compares to Tesla or Hyundai?
I quick scanned a lot of the comments here and many of them are answering your TITLE statement about car brands but the body of your question is about EVs, this is entirely different.
Experience with past ICE dealer service has little to nothing to do with future EV service. Many big name ICE dealers with great historical reputations are completely incapable of handling significant EV problems at the local dealer level.
Wonderful supportive delightful annual oil changes do not translate to software, battery pack, diagnostic capabilities. Many dealers do not even have qualified EV service techs.
Ideally your EV will have few problems. Ironically this is a problem for the dealers because repair is their biggest income source. If you’re looking for best EV service, you need to restrict your comparison to actual EV service.
