2012 Hyundai Genesis power train problems

“During normal driving conditions, the 8 speed automatic transmission will randomly hesitate to upshift from 2nd to 3rd and from 4th to 5th, causing an unpredictable loss of power. Symptoms will show up intermittently, and do not seem to be caused by certain events. This is unsafe because the unpredictability of the problem could cause power loss during moments where acceleration is needed to avoid an accident (moments which would otherwise be completely safe, i.e. merging onto a freeway, turning across incoming traffic, right turns into the direction of traffic, etc.) This problem already has a TSB issued by Hyundai. Problem has been reproduce by a technician. Component has been checked by a technician. There are no warning lights or other symptoms before failure.”
