ENGINE
I took the Kia to Hurst Dealership and Scott told me he would check it out. He called me and told me I needed the key replaced, so we paid them 230 dollars. Then he told me he found 4 recalls, fixed 3 of the 4 recalls. The last one, the engine seizing up, was still not complete. after 30 days we removed the car from that dealership because the whole time they were trying to sell us a car. Now the car doesnt even start, there is no key, there is lots of damage to the front end and underneath the engine is missing covers and who knows what else. Worst employees do the things the company itself tries to prevent, Scott is perfect for ruining reputations of the employers he (works for)

STEERING
Driving down the road and my steering wheel light comes on sporadically and then I lose control of the steering wheel like it locks up and is almost impossible to turn or rotate and then other dashboard lights come on and I lose headlights. When that happens traction control light on dashboard, the ABS light, battery light and steering wheel light that has an exclamation mark to right of it comes on. The car keeps driving and doesn’t die but all the abs and driving wheel lock up so you cannot be in control of the vehicle.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
The electrical wiring harness connecting to the hybrid system electric fuel pump(s) was found to have significant corrosion and a missing factory-installed protective covering. This is a manufacturing defect. The protective covering was never installed at the factory, leaving the wiring exposed to moisture and corrosion from the time the vehicle was built. COMPONENT THAT FAILED: Electrical wiring harness to hybrid electric fuel pump(s). Missing factory protective covering caused corrosion. The failed component is available for inspection upon request. SAFETY RISK: Corroded wiring in a hybrid vehicle electrical system poses serious risks including electrical shorts, potential fire hazard, and sudden loss of hybrid propulsion while driving. The vehicle is currently inoperable and unsafe to operate. CONFIRMED BY DEALER: Yes. The vehicle was taken to an authorized Kia dealership where it remained for approximately 8 months. The dealership and manufacturer inspected the vehicle and confirmed the wiring issue but denied warranty coverage. THIRD-PARTY CONFIRMATION: A third-party warranty representative independently reviewed photographic evidence and confirmed the missing protective covering is a manufacturing defect, not wear-and-tear or owner-caused damage. MANUFACTURER RESPONSE: The manufacturer denied warranty repair, falsely claiming the hybrid component warranty does not transfer to subsequent owners. Federal warranty law requires transfer unless explicitly excluded in the warranty terms. WARNING SIGNS: No warning lamps, messages, or symptoms appeared prior to the failure. The defect was hidden beneath the vehicle and not visible during normal operation or routine maintenance.

The only option is to return to the dealership and have the part replaced to allow the window to move up and down, This is a safety hazard and fails state inspection if the windows will not move up and down. This is a safety recall.

ENGINE
Consuming fuel to the amount of roughly 1/2 quart per 150 miles. Vehicle has been inspected by mechanic and the oil pan, oil filter, and PCV valve has been replaced and engine oil UV dye added and cycled with no leaks found. The risk is that if not rigorously checked often, the engine will malfunction because the car runs out of oil. I have had my mechanic checking this car since I purchased it in January 2026. We have had to replace the oil pan and do two full oil changes with three separate quarts of oil being added in between all of that to keep it topped up. My mechanic agrees that the engine is consuming oil at an extremely high rate. My mechanic and a mechanic at the dealership where I purchased it are the only one who has inspected the car for this issue so far. The mechanic at the dealership is who recommended we replace the oil pan to see if that fixed the leak, which my personal mechanic did. Yes the critical engine failure lamp illuminates on the dashboard when the oil ran out the first time while I was driving it. This was how I discovered that there was an oil leak. This specific incident occurred three weeks after I purchased the car which I bought in mid-January of 2026.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Brake pedal loses pressure and disengages with brakes. Traction light, maintenance light, hybrid system warning message, check brakes message and parking brake intermittently turns on and off. I called Kirby Kia of Ventura a few weeks ago and let them know about my issue with the car. I explained that I took the car to a mechanic and the diagnostic they did stated the issue with the car could be because of one of the recalls. On 4/10/26 I took my vehicle to Kirby Kia of Ventura for the recalls and asked if they could do the diagnostic. Raul from Kia was the service rep that spoke with me. He stated they would do the recalls and then, if needed, they would perform the diagnostic. Later that day Raul called me and stated the recalls were completed and no issues were found. Several items were found from Kia's point inspection, but none related to the issue at hand. I then asked Raul if they could perform the diagnostic to know what was wrong with my car and he stated that they could do the diagnostic on Monday, 4/13/26. Raul stated he would give me a call around 10 to 11 am, to discuss any issues. Raul called at 10:49 am, and stated no lights on the dashboard have come on and he didn't want to do the diagnostic because the lights weren't on. Kirby Kia of Ventura service department are crooks and only want to assist you if they get money out of you. My car still has the same issue, possibly damage to the HECU from the recall, but Kirby Kia didn't want to run the diagnostic on my car to find out if it was damaged. Kirby Kia of Ventura is a horrible organization and I will never purchase another Kia vehicle for this reason.
