2018 Kia Sorento Speed Control & Cruise Problems

Vehicle seems to be stalling when you stop and then try to pull out. It takes minutes to accelerate after stopping.

I was driving home from work when vehicle downshifted while on the interstate. I continued to drive and tried to accelerate but again the vehicle downshifted. I was able to drive home by not going over 50 miles per hour.

The contact owns a 2018 Kia Sorento. The contact stated that while accelerating, there was an abnormal knocking sound coming from the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure recurred. The mechanic completed a road test and indicated that the vehicle was working as designed. The vehicle was not diagnosed or repaired. The contact stated that while driving at 65 MPH, the vehicle was shuddering, shaking, and then lost motive power and stalled. The check engine warning light was illuminated. The contact used a code reader and retrieved DTC code: P1326 (Permanent go Relay Stuck On). The vehicle was taken to an independent mechanic, who cleared the codes but informed the contact that the failure would continue and recommended an engine replacement. The contact stated that while driving at 70 MPH, the check engine warning light illuminated. There was a thumping noise detected from the engine. The contact reduced the speed to 40 MPH. The vehicle began to hesitate, sputtered, and failed to accelerate. The contact used a code reader and retrieved DTC code: P0302 (Cylinder Misfire). The manufacturer was contacted, and opened a case. The failure mileage was approximately 95,000.

My car went into Sudden Unintended Acceleration when I shifted from neutral to drive. I was in a gas station that was perpendicular to highway traffic. When I attempted to come out of the car wash tunnel to get my car dried off, the car accelerated out of control, the gas pedal was stuck and the brakes would not engage. The car flew out of the tunnel and into traffic. The car hit a curb before entering into traffic and went airborne. I in the third lane of southbound traffic. The vehicle then continued on through a grass median and across three lanes of northbound traffic, hitting another curb. At sone point during this accident, three of the tires popped and drivers side airbags did deploy. The popped tires appears to be the reason why the car finally came to a stop. It is only by the grace of God that I made it out alive. The airbag burned my torso. This accident occurred on 5/19/2023 at approximately 4:15 pm. X-rays and cat scans revealed no additional injuries. Currently, I am waiting to be seen by an orthopedic doctor for pain in ankles, lower back and stiffness at base of neck. My insurance company concluded the car as a total loss.
