Tranny Problems Anyone?
 I too had issues with the transmission not wanting to shift.  Luckily I was near my home.  Nonetheless, I took it in and a computer reset was done - haven't had the issue since.  Otherwise, traded an 07 Escalade for this beauty.  I love it and would recommend it to anyone looking for sporty driving as well as utility.
