2022 Kia K5 Driver Assist & ADAS Problems

These warnings light up at the same time the dash for Electronic stability system, electronic parking brake, forward collision system, Auto hold and engine light, saying "check forward collision system, check blind spot detection, check smart cruise control system", and the vehicle goes into a sort of limp mode, not allowing it to accelerate past about 40 mph easily. In my research, I've have found approximately 50 other Kia k5 owners who have had this exact same issue. Half of the time, once taken to the dealership for diagnosis, it is weeks without anyone figuring out what the issue might be. Several instances where a part has been replaced which did not fix the issue at all, like an airbag module, or steering column. Several instances of the ecu and hecu being replaced, and several more of the entire engine/chassis wire harness being replaced. As for my case, now at the dealership for 2nd time because they could not reproduce warning lights while test driving vehicle. They have determined mine requires a full chassis wire harness replacement, with an estimated cost of $5k-$7k, which includes the $2800 harness. I initially thought mine was an isolated incident, and was shocked to find as many owners as I have that have experienced the same issue, some with mileage as low 25 miles, and causing sudden braking or issue with steering the vehicle. Being that it involves all the major safety systems of the vehicle, I am also surprised there has not been any sort of recall, considering these issues span all the way back to 2021. Just my two cents. Currently waiting on a tech to come out and determine if this is covered under extended warranty bought at dealership at time of purchase, as I am over the 60k mile factory warranty period. Have had this vehicle for 3+ years, and this just now started happening about a month and a half ago. Some have had this issue just weeks after leaving the lot with their brand new car, and a few of those returned the vehicle for a refund.
