I’ve got a 2017 limited with 64k miles that just had a transmission totally fail. Has anyone else seen this happen? I’ve averaged less than 10k miles per year and don’t tow anything. Dealership says I am 4k miles outside of powertrain warranty so nothing they can can do.
Call GM since you are close enough to warranty and see if you can escalate to get an exception. They might honor the warranty still, worth a try
