Genesis Coding Error

I'm officially pulling my hair out. I've got a 2015 Hyundai Genesis with a gasoline engine, only 40050 km on the clock, and I'm getting fault codes. The engine light is on, I’ve got error messages popping up, and the speedometer is throwing warnings. I scanned it and it's definitely throwing some codes. I'm thinking it might be a coding issue, like something got messed up in the software. Anyone else run into this?

A 2015 Hyundai Genesis owner is experiencing persistent fault codes, engine light warnings, and speedometer issues, suspecting a coding error in the vehicle's software. Despite clearing the codes, they reappear, suggesting a deeper issue. A workshop visit confirms incorrect vehicle coding as the cause, which is resolved through professional recoding, restoring the car to normal functionality.

Sounds frustrating! I've got a Genesis too, though not sure of the year, and I had something similar happen a while back. Kept getting random errors and the engine light. Did you try clearing the codes to see if they come back? Also, which fault codes are you seeing?

Yeah, I cleared the codes, but they came right back after a few minutes. The scan tool is showing a coding error, which is why I think the whole car is having a meltdown. It's almost as if the car thinks it's another car.

Ah, a coding error... that's beyond my limited skills, haha. When mine was doing weird stuff, it wasn't a coding problem. If the codes keep returning even after clearing them, I'd strongly suggest taking it to a workshop. They'll have the proper diagnostics to really dig into the coding side of things. Don't want to mess something up even worse!

I appreciate the insight. Looks like a workshop visit is definitely in order. I took your advice and brought it in, and you were spot on – incorrect vehicle coding was the culprit, and the repair set me back 360€. They recoded it, and everything's back to normal now.
