What owners say about the fuel/propulsion system

Verbatim from NHTSA complaints, newest first
“As the original owner of this 2016 Kia Soul (approx. 124,000 miles), I am filing this safety and consumer compliance complaint for severe engine failure and a failure of manufacturer recall notification systems. On [XXX], my vehicle experienced severe power loss on the highway and extreme oil consumption. An inspection by an independent repair facility revealed catastrophic engine failure due to piston ring degradation, severe crankcase blow-by, and oil contamination of the exhaust system. The repair shop informed me that these symptoms directly align with known manufacturing defects covered under active safety recalls, specifically NHTSA Recall 19V-120 and the Hyundai/Kia Engine Litigation II settlement (No. 8-18-cv-0223-JLS-JDE, C.D. Cal), for which my VIN is a confirmed match. On [XXX], I brought the vehicle to VanDevere Kia of Akron for evaluation. Service associate Jackie Mundri informed me I was denied engine replacement coverage, with Kia claiming I waited "too long" to address the recalls. When I escalated this to Kia Consumer Affairs and spoke with a representative named Cassandra, I was told it was my personal responsibility to proactively check for…”

“Vehicle suffered a sudden, dangerous loss of power on the highway at 70 mph, dropping immediately to 20 mph, creating a severe safety risk. The vehicle has an active P0420 code. The official NHTSA database confirms that Safety Recall SC176 (Campaign 19V120) is INCOMPLETE for this vehicle. However, the KIA dealership and KIA corporate are actively refusing to honor the federal recall, falsely claiming the vehicle is past an 8-year/80,000-mile emissions warranty limitation. They are also forcing a $249 diagnostic fee to investigate an open, incomplete safety campaign.”

“Component or system: Catalytic converter (exhaust emissions system). The converter is physically restricted due to substrate damage consistent with the defect identified in NHTSA Campaign 19V120 / Kia Recall SC176. The restriction limits engine RPM to approximately 3,000 under all conditions. The vehicle is available for inspection at any authorized Kia dealership. No DTC is stored because the restriction has not yet degraded catalytic efficiency below the ECU's threshold — the catalyst is still chemically functional but physically blocked. Safety risk: The RPM limitation prevents the vehicle from accelerating past ~3,000 RPM, creating a significant hazard when merging onto highways, passing in traffic, or climbing grades with risk of fire. The recall notice identifies the risk as "abnormal engine combustion and damage to pistons and possible piston connecting rod failure," which can result in sudden engine stall while in motion. The restriction is progressive and will worsen, increasing the likelihood of complete power loss. Reproduced or confirmed by a dealer: The vehicle was inspected at an authorized Kia dealer. The dealer scanned for DTCs, found none, and…”

“Whistling noise and problem with acceleration over 35mph and drifting uphill. Although VIN number did not appear on the listed recall, the repair work recommended and partially completed by Kia repair dealer points directly to the description of an oil consumption problem that includes the 2016 Kia Soul. Some repairs done at Kia XXX and some done at Scott Kia in [XXX] (where I reside).”
