March 2022, (approximately 72,000 miles)while driving to work my car shut off. I was in drive at a red light. Noticeable decreased acceleration and vibration. Took it to the dealership for routine oil change and mentioned incident. Technician was not able to find cause. Ok so be it. Now May at a little over 73,000 miles multiple lights began to illuminate and flash. Still with decreased acceleration it was noticed on a Friday morning on my way to work: 1. Oil light flashed on and off for approximately 2 minutes. 2. Air bag light stays on 3. Electronic Stability Control light stays on I scheduled an appointment for the next day. Took it into nearest Kia dealership. I was informed that my engine had no oil in it. The electrical board that signals my airbags and power steering is -€œmalfunctioning-€ and would need to be replaced. I was also told that since I just went for an oil change and was not due for another 3-4,000 miles maybe the -€œengine absorbed the oil as there are no visible leaks-€ I am set to return to Kia at the 1,000 mile mark to check oil levels to see if the oil is gone again. On my way to work again, on I-75 I felt extreme unsteadiness and loss of road grip with steering. Like I was loosing co trio of the vehicle while traveling at 55 miles an hour. As the original owner of this vehicle, with regular routine maintenance this is extremely concerning. I worry every day that my car will fail me and injure mine, my kids and others lives. I really hope this is looked into as a safety issue.

My air conditioner all of a sudden went out. No air would blow. Took it to Kia and it turns out that a fuse box blew on the main wiring harness, evidenced by burn marks on the bottom which then blew out my fan motor. Seems that Kia has had a lot of faulty wiring harnesses and it could have definetly caused a fire and is a safety hazard. My car is out of warranty by 8k miles and they are trying to make me pay for something that I believe is a defect as they said themselves that they cant even determine the cause as this is not normal wear and tear nor something I could have caused. I cannot afford to pay for this and I do believe that Kia needs to make this right. Because everything electrical plugs into this one wiring harness, they have to replace the whole thing costing over $3600. There was no warnings or lights that came on. I do believe that this also messed with the airbag sensor in the passenger seat as well. This is not right for consumers to have to worry about this. This is a 2017 car... it should not be failing.
