2018 Kia Sorento: jerking or lurching

Filed May 5, 2026 · Engine · NC

2018 Kia Sorento, under 88,000 miles, with Theta II engine defect. KSDS update installed. Oil consumption issues requiring adding at least one liter of oil every 1,000 miles in between regular oil changes/ maintenance. Oil warning lamp does not illuminate at all or only blinks on for a second then stays off, even when oil is less than 1 liter. Noticed slight jerking/hesitation at acceleration for a few days, then experienced shaking and heard vibrations when breaking and idling. Within a few minutes, MIL appeared with audible warning, "Take this vehicle to a Kia dealership." Immediately parked car. Towed to Kia dealership. No record of DTC P1326 found, which would have qualified vehicle for new engine under PI1802 Y/Z Theta II Extended Warranty. Diagnostic found misfiring cylinder and fouled spark plug. Technician in the video stated "oil consumption." Due to absence of P1326 code, service manager suggests we replace fouled plug and return with the vehicle when the same issue happens again. This does not follow Kia's own guidelines in PI1802 Y/Z campaign for a couple of reasons. First, activation of the MIL in conjunction with the audio warning indicates the Knock Sensor P1326 code should have been generated and stored, but the warning system must have malfunctioned. Service dept. did not to inspect the knock sensor harness for damage or oil saturation which could have kept the code from registering. Second, Service dept. did not consider shaking and vibration as "engine noise," which would have required them to perform a BCT or test for connecting rod bearing noise, providing a pathway to request Techline PWA approve replacing the engine under warranty. Kia's Product Improvement Campaign for Theta II engines ought to prevent injury or death resulting from catastrophic engine failure. My vehicle presents clear evidence of engine failure progression at different stages. Rather than navigate the warranty via a Techline, Kia has advised me to continue driving.

When trying to move the steering wheel, it initially sticks and requires extra force to get it to provide a steering input. Once it gets past the initial resistance, it jerks the car in the direction you are trying to go which required compensation in the other direction. Upon correction, it jerks the car in the opposite direction causing a continual need to correct the steering wheel to keep the car straight and causing the car to not be able to maintain perfectly straight travel. On large sweeping corners, this problem is even more pronounced and feels dangerous. This happens mostly on longer trips where the vehicle has been on the road more than 30 minutes.

When driving 40+ MPH, when the wind is blowing, the steering becomes sticky, notchy or jerky, call it what ever you please. When trying to adjust steering slightly to drive in a straight direction, my steering becomes jerky and dangerous. Kia refuses to look into this seriously. They want me spending hundreds of dollars to get it diagnosed. But how will it be diagnosed when it only happens when it is windy? Please help me with this.

While driving down the road the steering wheel sticks. While you keep turning a little to keep the vehicle straight it will suddenly break loose, causing the vehicle to jerk left or right depending on the direction you were turning the wheel at the time. It is most dangerous while the roads are either snow or ice covered and slippery. Hard to keep the vehicle on the road.
