What owners say about the power train

Verbatim from NHTSA complaints, newest first
“The Engine powered down to the point where the car stalled out. It would not accelerate. This was quite dangerous! I was in traffic when this happened. Trying to get it to a safer spot, I restarted the engine a few times; the brakes were extremely hard & wouldn't let me mash them down to catch to stop, so I immediately pulled the handbrake up & shut the engine off. I smelled a weird smell, like something was burning too. I had it towed to the shop & even though No lights were on, we plugged it up & it gave the 0420P code for the Bank 1 sensor Exhaust Flow issue. Mechanic stated he thought it might be the Catalytic Convertor. About 2 weeks beforehand, the oil light had come on, added 2 quarts of oil & it went out. Then the check engine light came on about 2 weeks after that, blinked a couple of times, but went back off.”

“COMPONENT FAILURE: The engine, power train, and speed control systems failed due to the known Nu 2.0L GDI connecting rod bearing defect. SAFETY RISK: My [XXX] daughter was driving in heavy rush-hour traffic when the vehicle suddenly lost motive power and entered a 20 MPH "limp mode." This sudden deceleration created an immediate and severe risk of a rear-end collision, endangering my daughter and surrounding motorists. DEALER CONFIRMATION: The failure was officially confirmed by Flow Kia of Charlottesville (RO #XXX). On Dec 3, 2025, the dealer confirmed active DTC P1326 (KSDS) and documented failed cylinder compression (as low as 150 PSI; min spec is 178 PSI). The dealer issued a written diagnosis stating: "engine replacement is required." MANUFACTURER CONDUCT: Despite their own dealer's written diagnosis and the active P1326 safety code, Kia Corporate issued a bad-faith warranty denial. The dealer also unlawfully charged me $165 for the mandatory KSDS warranty diagnostics. SUMMARY: This is a textbook safety failure under NHTSA Investigation EA 21-003. Kia's refusal to replace the engine under the court-supervised Engine Litigation II settlement represents a…”

“Summary of Safety Defect: While my 16 year old daughter was driving our 2014 Kia Soul in December 2025, the car suddenly lost power in traffic and would not go over 20 mph; the check engine light came on and the vehicle entered limp mode. The sudden drop in power created a high anxiety, hazardous situation for my daughter, who had only had her license for a week, during rush hour traffic. The vehicle was unsafe to operate and had to be towed. Details of the Incident: Diagnostic trouble code P1326 (Knock Sensor Detection System) was confirmed by the Kia dealership. P1326 is part of Kia’s known engine defect population and is tied to safety related engine failures. The dealership documented oil consumption, oil fouled spark plugs, and compression readings below Kia’s minimum specification on all cylinders. The dealership concluded in writing that engine replacement is required. Despite this, Kia denied warranty coverage based solely on a bearing clearance test, without completing the full diagnostic process required under the KSDS settlement. The vehicle remains unsafe and inoperable. Why This Is a Safety Issue: The sudden loss of power and inability to…”

“In June 2024, my 2014 Kia Soul (VIN: [XXX] ) experienced a sudden engine failure without warning. I was driving on a busy road when the engine began sputtering and quickly stalled. The vehicle became inoperable and had to be towed. I had it inspected at a Kia dealership, who diagnosed the issue as complete engine failure but have not provided me with a full diagnostic report despite multiple requests. This type of failure is consistent with the known defects in the Theta II engine that have triggered recalls and extended warranties in similar Kia models. Although Kia has denied coverage for my vehicle, I believe this is a related safety issue. The vehicle stalled unexpectedly, creating a hazardous condition on the road. I was traveling with my toddler in the back seat and felt our safety was at risk. I am submitting this complaint because I believe this failure is not an isolated incident and should be investigated. Kia has refused to acknowledge a defect, but the symptoms match those in previous recalls for other Soul and Forte models with similar engines. I have also attached documentation showing service history and repair costs, and I am happy to make the…”

“Q: What component or system failed or malfunctioned, and is it available for inspection upon request? A: My 2014 Kia Soul "threw a rod" (as confirmed by a Kia dealer in Jan 2025) at only 115,773 miles after years of regular (every 3-5K miles) maintenance. I bought the car used in 2017 and have documentation to show the maintenance for the subsequent years. The particular motor at issue is known by mechanics to have problems (according to my own mechanic and at least two others with whom I have communicated, as well as on-line research). However, there is no active recall on it, and the car is "out of warranty." As of the date of this complaint, the car currently is available for inspection upon request. Q: How was your safety or the safety of others put at risk? A: It is my understanding that throwing a rod is a catastrophic engine failure and can result in loss of control of the vehicle, potentially leading to accidents, as the engine may seize or lose power abruptly. Furthermore, the broken rod can cause the engine to explode, leak oil, or punch a hole in the engine block, posing a risk of fire or further damage. I am lucky that I noted a reduction in engine…”
