NHTSA Complaint #11615169 — 2023 HYUNDAI SONATA

I have been having transmission issues the whole time I've had the car. There is a delay upon take off, and it bogs down instead of downshifting. I was driving my son to school and made a left turn. It started to go but then delayed for 10 seconds before suddenly taking off. If the on coming traffic had been closer, they would've hit us. The dealer has reproduced the problem but can't get enough information for the tech line to approve a new transmission even though the dealership has repeatedly said that is what it needs. I've never had a warning light on it. it's been in the shop for it this time since 7/26/24.
