NHTSA Complaint #11580384 — 2015 KIA SOUL

The contact owns a 2015 Kia Soul. The contact stated while driving at various speeds and depressing the accelerator pedal, the engine would rev up loudly emitting a vibrating noise. About 3 months after having the vehicle repaired, while driving approximately 30-40 MPH, the battery warning light and the oil warning light illuminated, and the vehicle stalled shortly afterward. After waiting for a while, the contact was able to restart the vehicle; however, the contact was only able to drive for a short while before the failure recurred. The contact stated after having the vehicle inspected, there was smoke coming from underneath the hood and the tailpipe intermittently that dissipated while driving. A loud vibrating noise was emitted from the vehicle while driving at various speeds. The vehicle was taken to a muffler shop after noticing the loud vibrating sounds and it was determined that the muffler was loosened and needed to be reattached. The contact had also taken the vehicle to an independent mechanic due to the vehicle continuing to run roughly and it was determined that cylinder #1 was misfiring. Additionally, the oil level was extremely low. The mechanic was unable to determine where the leak was coming from. The ignition coils were replaced. The contact stated that a friend diagnosed the vehicle and retrieved a code that cylinder #4 was misfiring after the coils were replaced. The friend also informed the contact that the failure was related to NHTSA Campaign Number 19V120000 (Engine, Engine, and Engine Cooling). The vehicle was taken to the dealer where it was diagnosed that the engine had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and confirmed that VIN was not included in a recall nor covered under warranty. The failure mileage was 178,000.
