2019 Kia Forte problems

“The contact owns a 2019 Kia Forte. The contact stated that while driving at 70-75 MPH, the vehicle lost motive power and the check engine warning light illuminated, causing the contact and her daughter to be stranded on the highway. The vehicle was towed to an independent mechanic, who replaced the spark plugs and ignition coils; however, the failure persisted. After allowing the vehicle to cool down, the contact restarted the vehicle and drove to the residence. The vehicle was then taken to Jiffy Lube, where the transmission fluid was changed; however, the failure recurred. The vehicle was towed to the dealer, where DTC P0730 was retrieved, indicating an Incorrect Gear Ratio, and the dealer determined that the transmission needed to be replaced. The contact associated the failure with Technical Service Bulletin: MC-11029037 and Voluntary Emissions Service Campaign SC199; however, the vehicle was not covered under either program. The manufacturer was notified of the failure by phone. The failure mileage was approximately 106,000.”

“I took my 2019 Kia Forte LXS to a certified Kia dealership to have the mandatory anti-theft security upgrade performed (Campaign CS2312), which involves installing an ignition cylinder protector plate inside the steering column. Immediately after picking up the vehicle, multiple severe safety and electrical defects appeared. The engine is running very rough, sputters, and loses power especially going up hills, making it dangerous to drive. Additionally, the brake light main is now malfunctioning and fail to illuminate. - creating an immediate crash hazard. The radio and dashboard electronics are also cutting out intermittently. mileage is also not being calculated right. These dangerous engine and electrical safety defects were directly caused by the dealership's botched installation of the manufacturer's security campaign."”

“While driving, the Forward Collision Warning system activated unexpectedly without any apparent hazard or obstruction in front of my vehicle. Immediately after the warning appeared, the vehicle suddenly lost speed and became very slow to accelerate. I was unable to safely increase my speed while traveling on a busy roadway, creating a dangerous situation and nearly resulting in a collision with surrounding traffic. Due to the sudden loss of power and inability to accelerate normally, I activated my hazard lights and was forced to pull onto the shoulder of the road for my safety and the safety of other drivers. There were no visible obstacles, vehicles, or road conditions that appeared to justify the activation of the Forward Collision Warning system. This unexpected activation and resulting loss of vehicle performance created a significant safety risk. I am submitting this complaint because a malfunction of the Forward Collision Warning system or related vehicle systems could potentially lead to a serious accident or injury. I have experienced recurring brake issues despite recently having the brakes replaced. The problem continues to occur, raising concerns…”

When I try to accelerate my vehicle it would take a while to accelerate. March 7th 2026, while I was driving, my car quit while it was still running. It also quit the same day again just in park. March 8th 2026, I went to take my vehicle to get a diagnostics and when leaving my home. My car stalled out and quit while in drive. After taking my vehicle to the mechanic, the mechanic reported to me my car had no oil in my car and my motor was fried. I have had the vehicle less than a year and it’s giving me all of these issues”
