less than 1800 miles -auto transmission- won't go into reverse

That's not good! Has the dealer taken it in yet? Curious to hear what went wrong.

at dealership and tow driver said he delivered another trailblazer same year to the same dealership same day and that one would not go forward and they have not even checked out mine after 2
days and though I am entitled to a loaner they said none available at this time

Thanks for the update and please post what the dealership finds in case someone else has a similar problem. My guess is a faulty shifter or software related problem. Hopefully it's not the transmission.

I have 21 RS and experience long delay when putting in reverse sometimes. It just sits there and will not move. Emergency brake is off in garage. Dealer could not reproduce issue.
