What owners say about the electrical system
Verbatim from NHTSA complaints, newest first
“The vehicle has experienced intermittent stalling and near-stalling while driving. The problem began after a prior Kia engine replacement related to DTC P1327/P132700. After the engine replacement, the vehicle developed additional drivability and warning-light concerns, including P0420 and communication/CAN faults. An authorized Kia dealer later documented that the vehicle had stalled a few times, identified P0420, reported a clogged catalytic converter, and found 11 additional lost-communication/CAN-related codes. The dealer stated that approximately eight additional diagnostic labor hours would be required to investigate the remaining faults. The vehicle was returned with the intermittent stalling condition unresolved. The stalling presents a safety risk because the vehicle can lose motive power unexpectedly while being driven. The vehicle remains available for inspection. The dealer confirmed the stalling complaint and performed diagnostic testing, but the complete cause has not been determined. Kia previously performed an engine replacement related to the earlier P1327 condition, and the current stalling occurred afterward.”
“Engine shut off while making a turn. Took car to mechanic and he stated that the car did not display any error messages. The car also over heated while driving in freeway.”
“My Car would shut off in the middle of the road after I stopped to make a turn or even stop at a stop light. Also the engine is burning oil. Mechanic says the the engine needs to be replace. Something with the oil piston and the exhaust is burning oil. I am not sure”
“The contact owns a 2020 Kia Soul. The contact stated that while driving at an undisclosed speed, the vehicle stalled. The automatic start warning light illuminated, and the engine seized. Additionally, the error message indicated that the automatic start feature was disabled; however, the contact stated that the automatic start feature was enabled. The contact stated that while attempting to start the vehicle, the vehicle failed to start. After several attempts, the vehicle started. The contact disabled the automatic start feature. The contact stated that while the vehicle was decelerating, the failure reoccurred. The vehicle was taken to the dealer; however, a diagnostic test was not performed. The contact stated that the diagnostic test was incomplete. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,924.”
“Second engine installed in the car ceases to fire. Condition does not change with new sensors for camshaft nor crankshaft. Engine turns freely cranks but will not restart. Unreliable driving conditions. Mathew’s Kia wants $1400 upfront to start exam in blind faith to see if a properly serviced car has a common warranty claim”
“To Whom It May Concern, I am writing to formally submit a complaint regarding the handling of my vehicle recall and repair process at Kia Killian Road in Columbia, South Carolina. Vehicle Information: - Year/Make/Model: 2020 Kia Soul - VIN: [XXX] - Registered Owner: [XXX] Timeline of Events: - My vehicle was brought to Kia Killian Road for recall repairs related to recalls 21V259, 21V259A, and CS2306 concerning the engine and starter. - The starter was replaced as part of the recall work. Despite this, the vehicle remained at the dealership for over a month and a half without resolution. - I was then informed I would need to pay approximately $1,200 to replace the ignition, even though there had been no issue with the ignition prior to the recall service. - The ignition was replaced at my cost, but I have since been informed that my vehicle is still not repaired due to an alleged electrical issue. - At the time of this complaint, my vehicle has been at the dealership for more than 2.5 months, and I have been given inconsistent explanations and no resolution. Concerns: - The dealership appears to be tying unrelated repairs to the recall, causing unnecessary…”
