I didn't have this car at 3500 miles when others lost transmissions, but I have had it at 60k (lost again). Now I hear I need to fix it again (jarring gears). I included traction control problems last time. I did not run it hard (I drive like grandma on purpose) but it did not solve this $4000 later. It runs quiet and smooth sometimes, but I can't put off a transmission repair for complications failure would have - seen elsewhere. It was in the shop a long time despite being partially covered by a plan and monitored for that. They damaged some other features while fixing it at an approved GM dealership (i.e. driver seat warmer).
I do love how smooth it runs when it runs and how quietly and quickly. The miles per gallon are decent when driven right (ave 21 city hilly 28 hwy or better). The features and sound are great. Like the leather.
