ACC Issue on Ioniq 5!

[Satabdimitra20]

So I’ve got this 2023 I5 AWD Limited with about 12k miles, and I’m dealing with a funky issue with the ACC. After cruising on the highway for like 50-60 miles, my car’s speed randomly drops by 3-5 mph. Then it jerks forward to catch up, and this happens even after ACC is turned off. It’s like my accelerator takes a nap until the car decides to slow down by itself. Super annoying! Anybody else run into this? Any ideas on how to fix it?

Did you try scanning it to check if there are some trouble codes?

Did you take it to your dealer? I suspect it's your rear motor overheating and cuts power to the system.
