Accent Transmission Control Unit Issue

I'm having issues with my 2023 Hyundai Accent with a gasoline engine. It's got about 194626 km on it. The main problem seems to be a defective transmission control unit. I'm getting symptoms like shifting not possible using the paddle shifters, the gearbox slips and shifts pretty rough, and there are some nasty grinding noises when it shifts. The paddle shifters are super slow to respond, and the gearbox has gone into emergency mode. The error memory is also showing a fault. Has anyone else experienced something similar?

Sounds rough! I've got an Accent myself, and I had similar issues a while back. Shifting was a nightmare, and it turned out to be the transmission control module acting up. Does it feel like it's stuck in a gear sometimes?

Yeah, it definitely feels like it's stuck sometimes, especially when it goes into emergency mode. Was it the same symptoms for you? And how did you figure out it was the control module specifically?

Yep, pretty much identical. The emergency mode thing is a dead giveaway. I initially thought it was just bad luck, but the error codes pointed the mechanics directly to the control module. Honestly, with all those symptoms, especially the emergency mode and stored error, I'd strongly suggest getting it checked out by a workshop. It's likely the control unit, and those transmission issues can snowball into something worse quickly. Cost me around 1000€ to fix, control unit was defective.

Thanks a lot for the info! I'll definitely take it to the workshop ASAP. Knowing it's likely the control unit helps a lot. Looks like I'm in for a similar repair bill. I'll post what happens once it's sorted.
