Mine does in 2nd and stays in second until I accelerate. Then pops down into first. It's weird as hell but both my hometown and actual dealer said it was mostly normal. They said gears would fix that though. Remember also these cars have more hp than torque.
I put it in 1st manually and problem solved. Or just hard launch it for a second

Your dealer is yanking your chain. If you come to a complete stop your car should shift to 1st gear. If a rolling stop perhaps not but like you say then it depends on throttle. When coming to a complete stop if your auto takes off in 2nd it is not normal.
Granted mine has 3:31 but my buddy has 2:73 with no issues.
