    The check engine light has come on. The vehicle has stalled or loss power while driving 3 times with the last week. Once at 70 mph and the other 2 at 35 mph. Still very concerning on how to control when this occurs!!

    - Aloha, OR

    I'm not sure which component caused the issue, but this happened a couple of times already, when I stepped on the accelerator pedal, but the vehicle didn't response at all. The first time, when I was turning into a parking lot, I had to let off the gas pedal, and try it again. The second time this happened was very scary, I was trying to get on to the main road, but I was coming up from a steep hill side road, and I saw a car was coming, but I should have enough/time distance to get on the road, but after the initial acceleration, the car moved forward, but when I applied more power, but it wouldn't move at all! Luckily the oncoming car slowered down and let me go, I was on the opposite lane (incoming traffic), and luckily no car was coming my way. This is 100% safety issue!!!

  • 2019 KIA SORENTO
    - Portland, OR

    I am reporting a recurring defect with my 2019 Kia Sorento’s front axle assembly, which has failed multiple times despite repeated replacements. The vehicle was serviced at Ron Tonkin Kia, where the front axle assembly was replaced three times due to leaks: •January 2022 – First replacement •November 2022 – Second replacement •March 2023 – Third replacement The issue is happening again, indicating a persistent defect. Each time, the axle assembly has been replaced under warranty, but the problem continues to recur, raising concerns about long-term safety and reliability. I am concerned about the potential risk of axle failure while driving, which could lead to loss of vehicle control or other safety hazards. I am requesting an investigation into whether this issue is widespread and whether Kia should be required to address it through a recall or permanent fix.

  • 2014 KIA SOUL
    - FATETTEVILLE, NC

    When I was at work and driving in the parking lot the brake pedal went to the floor. I realized that I didn't have any brakes so I used my emergency brakes to stop. I checked and looked to find the problem: the pressure brake line was leaking under the car before the gas tank. I got my vehicle towed home by AAA. The next day I called the local dealership for the part and they didn't have one and said they could not get one. I waited for the snow to clear here in NC and for the weather to warm up before attempting to replace the line, my next option was the vehicle recycling center (Junk Yard). When I went to look at same-year models and vehicles, they were all rusted in the same place. Please look into this problem before someone gets killed.

  • 2016 KIA SOUL
    - Los Angeles, CA

    The contact owns a 2016 Kia Soul. The contact stated that the engine was consuming an excessive amount of engine oil. No warning light was illuminated. The contact was adding seven quarts of oil every 3,000 miles driven. The vehicle was taken to a dealer where it was diagnosed and determined that the engine was leaking engine oil. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

    - Indianapolis, IN

    Oil pressure sender unit is failing on these vehicles. There are several reports on the forums about this issue. First, the oil pressure warning light appeared on the dash. I brought my vehicle to an independent service center and they performed a diagnostic. They confirmed that the oil pressure sender was bad and filling with oil. This is a fire risk as oil is leaking in a hot engine compartment. Also, as oil is lost, it could result in complete engine failure while traveling at high speeds.

  • 2021 KIA SELTOS
    - Centennial, CO

    Horn stopped working. This puts me and passengers at a safety risk as I am unable to alert other drivers and/or pedestrians to potential dangers that could result in reducing the chance of a crash. I am also unable to use the horn to ensure proper security of my car. As the horn also works for my alarm systems to indicate the vehicles locked status. I also cannot utilize the horn as an emergency warning when the panic button is pressed on a key fob. The problem was inspected and determined at my local shop. There were no warning lamps, messages or other symptoms prior to the failure. The horn stopped working on Jan 29, 2025
