2017 Kia Soul: sudden loss of power

Filed Mar 21, 2026 · Engine · TX

Driving on busy highway with one passenger. Vehicle began losing power and acceleration, but no warning lights came on. Kept driving for 20 miles and oil warning light came on, but temp vuage registered fine. I parked, checked fluid amounts, and oil was extremely low (even though it had been checked the week prior and was full). Put 2 quarts in, started vehicle and warning lights went off. Proceeded back on to highway, drove 5 miles and engine lost acceleration and started knocking loudly, and all the warning gauges lit up. I pulled into parking lot, turned off the vehicle. Checked oil level and it was fine. Got towed home. Fairly certain it's the rod bearing. Engine has about 103,000 miles on it and has been well maintained. I see so many of this exact complaint, but our year model seemed to be ignored with a recall. Have loved our Kia's until now. Watchable got Hyundai?

While driving under normal conditions, the check engine light began flashing and the vehicle suddenly lost power and entered limp mode. Acceleration was severely limited, making it difficult to maintain speed in traffic. The vehicle was later diagnosed with diagnostic trouble code P1326, which is associated with engine rod bearing failure. This caused an unexpected loss of engine power and created a safety risk while driving. The vehicle had to be taken to a dealership for inspection due to the severity of the power loss.

While driving, the vehicle suffered a sudden and total engine seizure and loss of power (stalling), creating a life-threatening hazard in traffic . A certified Kia technician diagnosed a seized short block, multi-cylinder misfires (P0300-P0304), and a hole in the exhaust valve. This failure is identical to the defects in Recall SC176 and the Engine Litigation II Settlement. Furthermore, the dealer previously refused my request for the KSDS safety software update, which would have prevented this catastrophic seizure by triggering Limp Home Mode.

On 11/07/22 my car started to sputter & lose power while going up a hill, the incident only lasted a few seconds with no warning lights. Later that same day my car wouldn't start and when it finally did start it started sputtering, had no power with no warning lights, plus there was a strong smell of gas from inside the car. I had the car towed to a local shop. The shop cleaned the injectors, put a fuel treatment in the tank and replaced a bad O2 censor. 8 Days later on another hill it happened again. A hard sputtering followed by loss of power, still no warning lights but also no smell of gas. I drove it back to the same shop and after just one day the shop could not get my car to reproduce the same incident but was having difficulty starting it so they installed a new battery. 5 Days later on Thanksgiving my car sputtered hard while driving with no warning lights or smell of gas. I was barely able to get my car across 2 lanes of oncoming traffic in order to pull into a store's parking lot. I had it towed to a new shop. At this new shop it was diagnosed that the car needed new Spark Plugs, a new High Pressure Fuel Pump and new Injectors but the shop took 3 weeks to give me an estimate and so I went and retrieved my car and towed it KIA of Lynchburg, having only had the Spark Plugs replaced. Once at KIA, I was told I had a Catalytic Converter failure and it needed replacing. KIA said that it would be covered under Emissions Warranty. I had the part installed and 3 days later on New Years Eve as I was driving on the highway, I had to come to a stop due to a stop light and when I halted, the car again sputtered and I limped into a nearby parking lot and had it towed back to KIA. KIA tried to say it was Engine Failure this time but the Engineers said the High Pressure Fuel Pump should be replaced. Once installed and during a test drive by the Master Mechanic, smoke emanated from under the hood. Soon after that my Engine bay was on fire which led to a total loss.

The number 2 compressor(if I’m wording correctly) in engine failed causing the engine to be useless. When failed the engine reduced power, sputtered and began knocking. Fumes filled the cabin. We immediately pulled over and stopped driving. A repair shop did the compression test and confirmed the failure. 126,000 miles. Less than 5 years old. Just out of warranty. Car used to commute to work in metroplex only. Oil changes every six weeks

Upon startup one day, the engine began knocking. It was turned off and towed. Both an independent service center and Kia dealer have confirmed connecting rod failure, and the need for a total engine replacement. The vehicle is still available for inspection at this time. Fortunately, the issue began when the engine was turned on so the car was not moving at the time of failure, but had it begun on the highway or had a portion of the rod perforated the engine, it could have led to immediate loss of power while in motion and/or leaking oil. There were no warning lamps or messages prior to failure, and the engine had been maintained according to manufacturer guidelines. Periodically prior to this occurrence, the engine did demonstrate temporary reductions in power when accelerating, like it was hesitating to rev up beyond idle speed. However, the local Kia dealer was unable to diagnose the problem at that time (53,293 miles), and simply said to come back if it got worse, giving me the phone number for Kia Roadside Service. Although the loss of power was always temporary and infrequent, it could be a bit surprising when making a right turn into moving traffic, or a left turn across traffic because the car did not move into the traffic as fast as usual, which could have led to a collision with oncoming traffic. Fortunately it never lasted more than a second or two at a time. These symptoms returned the day prior to engine failure in greater frequency and duration. This type of failure is highly unusual for a vehicle of this age (4 years old) and mileage (67,000 miles), and Kia has denied warranty coverage, even though engine issues began before expiration of the warranty.

On Tuesday July 27 2021, we noticed that the oil light was flickering at idle on our 2017 Kia Soul. We called a dealership and they recommended that we have the car towed to their service department. We received confirmation that the car arrived at the dealership at 1.32 pm on Tuesday July 27 2021. We’d like to note that our 2017 Kia Soul had approximately 20,000 miles on it at this time. The dealership ran diagnostics on car and found nothing wrong. They also drove the car and said that they saw no indication of a problem (no flickering oil light). They said that the oil looked dark and thin. We had checked the oil the day before and it looked yellow to gold in color. We were not shown any evidence that the oil was dark, only the word of the service department. We had the car serviced and then picked it up from the dealership. 10 minutes or so after picking the car up from the dealership, on Colorado Highway 58 heading west, just outside Golden, CO, there was a loud knocking noise and the check engine and oil pressure lights starting blinking. Seconds later, the car lost power, and then stalled. My husband was able to steer it to side of the highway, where we waited more than three hours for roadside assistance from Kia before having to leave the car to get somewhere safe. The outside temperatures were 90 degrees of more and our child, who was with us, is very sensitive to high temperatures. We are waiting to hear from the dealership (Kia towing somehow managed to cancel the tow order and left the car on the side of the road all night) and do not yet know the exact nature of the engine failure but the car is undriveable. The fact that the engine stalled and died on the highway, traveling at a speed of 55 mph, is incredibly dangerous and put my husband at extreme risk for an accident or the infamous Kia engine fire. All of this happened just minutes after picking up a car that we were told had no issues.

Without warning indicators, my car lost power while I was driving it on a busy highway. I was able to coast onto an exit and a friend towed it to a safe area. I discovered there was no oil in the engine, even though I had had a recent oil change and no indicator on the car showed a problem with oil pressure, excessive heat, etc. I added oil and drove it a few feet to a secure location, but heard engine knocking. I called a mechanic, who inspected it and confirmed that a rod was thrown and the engine would need to be replaced. He is sourcing the replacement currently. This is a 2017 Kia Soul, 2.0 engine.

Engine- 2017 kia soul 2.0 l 4-cyl. Mileage at the time of purchase 42,788. Mileage at failure was 89,144. Usage predominately hwy miles. At the time of failure, we owned the vehicle 19 months. Regular oil changes with castrol gtx and edge 100% synthetic 5w20 oil. February 02, 2020 my wife started the day driving away from home. The outside temperature in the 60's and sunny. Drove 4.5 miles traveling 45mph on a straight level city roadway in heavy traffic. She could have been rear-ended or when turning off the roadway with loss of power t-boned trying to exit the roadway in an emergency. There is no breakdown lane or enough ground on the side of the roadway to pull off. All of a sudden, for no reason, the engine lost power and made a knocking sound. She checked the instrument panel, no warning lights. Temperature gauge read normal. Within seconds, she pulled into a parking lot and turned off the motor. No visible signs of any damage on the exterior of the motor or underneath the vehicle. We are the second owner of this vehicle. Manufactures initial transferable warranty expired. We towed the vehicle to our regular ase certified mechanic. They determined the issue to be a rod knock. Further diagnosis determined from a compression test the #2 cylinder is at 80#'s compression the other three at 150#'s. I have read your report regarding the ongoing investigation into kia's motor failures. I believe this motor should be included in the investigation although both VIN searches turned up no recall on my vehicle. We are currently trying to get the local dealer to work on the vehicle and they want to charge a minimum fee of 1500-1600 to tear the motor down and complete an investigation into why the motor failed. We have an aftermarket warranty program and they are trying to find a way not to pay for any claim on this issue. Our dilemma is ongoing at the time of this complaint.
