NHTSA Complaint #11608352 — 2017 HYUNDAI TUCSON

The problem began in mid to late April 2024 with the Tucson shuddering in the driveway while moving forward slowly. This vehicle has a 1.6L turbo with a dual clutch transmission. The mileage was around 96,000 miles. Once on the road, it ran fine. Approximately a month later the check engine light came on and it began hesitating upon acceleration. It would change to the next gear, accelerate and slam me against the seat! Whenever I try to accelerate too fast, it hesitates and loses power until it "catches" and starts speeding up. This is very dangerous especially when accelerating from a complete stop or after a turn. It also has trouble going up a hill and has actually died out 3 times while attempting to go uphill at a low speed. I am the second owner and it is out of warranty. I have contacted the local Hyundai dealer but their shop does not have a very good reputation and is always backed up for 3+ weeks. They also charge $230 or more to hook up their code reader!! I've already taken it to 2 other shops where that was done at no charge. The code was P073F - Unable to engage gear 1. Of course the only option I've been given is to replace the transmission for $3000 or have it rebuilt for $4100. This problem makes it very dangerous to continue driving it. I get the oil changed every 5000 miles. Of course it's almost paid for but I'm afraid if I try to trade it in I'll be lucky to even get enough to pay it off. I have been endlessly researching this online for recalls, updates or remedies. I want to know if replacing the entire transmission is the only option or is it a component of the transmission or a computer module that is the cause. How do I know the new transmission won't do the same thing?
