My engine is completely gone! I’ve been having issues with my oil since I’ve got the car and when I check my oil it’s almost always empty it’s a oil leak in the car and it’s not leaking on the ground it’s going elsewhere! A lot of mechanics have told me the same thing! I get my oil change every time it’s required.
Power train, Feb 8, 2024, crash
In April 2023 I purchased a 2021 Kia Soul. I had no issues at all with my Used Kia Soul. In Nov 2023 I was in an accident. I hit a deer and that did cause damage. My insurance company fixed it. I got my car back in Dec [XX], 2023 with approximately 96,000 miles on it. A few days later on my way to work. I entered the highway the car was running fine at 70mph then all of a sudden it lost power.. No power in the middle of the busy Atlanta Highway!! I was able to coast onto the shoulder. At that point I turned the car off. Turn the car back on to see if I was able to get it into Drive. Unfortunately that didn’t work my car didn’t move at all. I had to call the tow company get it towed back down to the collision shop. Only for the collision shop to send it to a Kia dealership. My car had been at the dealership for a few weeks. Today is February 8. I got the notice from my insurance company that the Kia dealership said I had metal shavings inside of my transmission and fluid. How does that happen? Then I decided to do some research and I noticed that this transmission is a problem. Not only a problem for people that are struggling with bills and finance charges but a problem with the manufacturing of this product. I’m not sure why there isn’t a recall on this transmission, if I was unable to get off of the highway I would have been hit. What is being done about this problem? To add injury to insult my 100,000 mile warranty isn’t any good because I’m the second owner of the car. I don’t understand how this isn’t a safety recall issue.

For years I have been experiencing the vehicle stalling, shutting off while driving, smelling oil burning and oil is disappearing which has me going to get an oil change every 1000 miles. Low oil light has never came on even when oil reservoir has been bone dry. My safety is jeopardized every time I drive this vehicle. This issue has been addressed to service center and they state according to Kia the excessive oil leak is “normal” and it’s not with any other vehicle. Also the service center does not know why oil is leaking or where oil is leaking which is a major concern. I no longer have free oil changes because I have used them all up due to multiple services for oil changes. Mind you I bought the car new in 2021.

Suspension, Nov 13, 2023
Turned my wheel to pull out of a parking spot. I heard a grinding noise as I moved forward and then lost the ability to steer my car. I was able to get my car off the street and upon inspection found my left front tie rod had snapped in half.
Electrical system, Other or unspecified, Nov 3, 2023
My 2021 Kia Soul was an attempted theft. The vehicle was locked and the would-be thieves gained access by breaking the passenger rear window. The True failure is in the ignition system. As the thieves tore apart the steering column and dismantled the ignition system, and they were ready to pull away before being interrupted. This defect in the simplicity and ease of access to the ignition system without ANY safe guards to prevent theft poses a safety risk to those who may interrupt would-be thieves in the action. While also posing a risk to the general public by inciting further possible road hazards, due to the nature of those operating the vehicles.
Steering, Oct 30, 2023
First off I do not use my lane keep assist. When traveling at any speed on a long curves of 100 to 150 ft or longer or sitting in a parking lot with the steering wheel angled between 15 to 30 degrees either left or right of center for 15 to 30 seconds the system will (in a sense) fall asleep. On the long corners this causes a dangerous situation for the driver and others because with the system falls asleep it will continue tracking the same course without recentering unless forced to re-engage. In other words it will not come out of the curve without forceful input from the driver. The vehicle has been in to the dealer where the issue has been dulpicated and confirmed by two technicians and dismissed by master tech without actually test driving. This issue should be labeled warning because serious injury or death will eventually happen.

We were traveling on the freeway 70 mph surrounded by heavy traffic at night, the vehicle started surging and bucking, shaking violently. The rpm's swung wildly from 2000 to above 3500 and car started to decelerate quickly in heavy traffic. I was able to get the car into right lane but feared being rear ended due to speed falling abruptly. Even though accelerator was being depressed and engine running car would not go and loosing power fast. I was able to turn off at an exit and there was just enough enough power to make it up a slight hill and turn right onto a round-a-bout where the vehicle would no longer move, abruptly stopping the fast traffic behind and again fearing a rear end collision to us. The engine produced power but nothing going to wheels, it was as if vehicle was in neutral no matter where the shift selector was placed. The police helped to push us off the road into a parking lot.

Vehicle shuts off after being idle (stopped at a red light, stopped in traffic). It goes completely dead & will not turn back on for 5 minutes or so. I have had the car for 11 months & it is currently at the dealership having the engine replaced for the third time. Kia has diagnosed the problem as “low compression” in the engine but does not know why so their solution is replacing the engine whenever it starts stalling again.
Engine, Jul 8, 2023, fire
I was driving and car started to lose power,the service engine light came on less than a minute before the boom.l tried to speed up and then there was a big boom and it was loud, so I went to the shoulder of the road and the car stalled ,I tried to restart the car and it just engulfed into flames. The car is a total loss. That's all that was left was a metal shell.

I was on the freeway, and the car was shuddering a bit before I lost the ability to accelerate. It would rev but no power to the wheels. Had to pull over and get towed to the dealer. I think it may be a transmission failure.

The contact owns a 2021 Kia Soul. The contact stated that after he purchased the vehicle, while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was inspected by an independent mechanic and the contact was informed that the crank sensor was faulty. The contact was advised to take the vehicle to the dealer for assistance. The vehicle was then taken to the dealer where it was inspected and diagnosed that the drain plug gasket needed to be replaced and that every 1,000 miles a quart of oil needed to be added. The vehicle was repaired; however, the contact stated that he was concerned that he had to add a quart of oil every 1,000 miles. The manufacturer was notified of the failure. The failure mileage was approximately 20,000.

I bought my 2021 Kia Soul on 10/21/20. Then on 11/11/20 my car started having transmission issues within less than one month of ownership & nearly 1000 miles on it. The transmission was replaced in late Nov./early Dec. of 2020. On 12/15/22, My Soul started revving up & the RPM needle was bouncing while driving, but the car would not go any faster when I pressed the gas pedal. I realized, I was having transmission issues with my 2021 Kia Soul, AGAIN. The car has less than 37,500 miles on it. I contacted Power Kia of Salem Oregon that day & the first appointment that I could get was on 12/29/22. I had the car towed to Power Kia on 12/27/22, then received a voicemail & text msg. from Power Kia on 12/28/22 that they will diagnose the issue. That was the last time that I got any information about my car without me contacting them. It has been OVER THREE MONTHS & Power Kia STILL has my vehicle & has not bothered to contact me with updates unless initiated by me. They have not provided any assistance for transpiration during this difficulty, even though that I told them multiple times, that I commute 80 miles daily. I bought a brand-new car to have reliable transportation to & from work, only to have to replace the transmission TWICE & be without my vehicle for nearly four months. The complete disregard of my safety by Power Kia when driving a car with a faulty transmission is reprehensible. I have developed anxiety issues, have had sleepless nights, and now have panic attacks just at the thought of dealing with this matter.

I own a 2021 Kia Soul with 34,130 miles. Purchase brand new in 5/21. I just had it serviced on 2/3/23. On 2/10/23, I was driving toward home on I-40 east, near mile marker 418 and the rpms suddenly started to jump up and down from 1000x to 6000x and the car had no ability to go anywhere close to the speed limit. There was a whistle noise coming from under the car. I took the I-81 north interchange to try to get the 80 or so miles back home but could not get the vehicle to go more than 15 mph. I was terrified I was going to get hit by the 18 wheelers whizzing by me. I got in the break down lane and limped to exit 8. The car began to shake violently and barely move. I got off the exit ramp praying no one would rear end me. I called Kia roadside and they towed it to the closest dealership in Moristown because they only tow up to 50 miles, unless I paid the requested $300+ to take it the extra 30 miles to my dealership where I bought the car. The service department called on 2/11/23 to tell me it was being evaluated now, but I have heard nothing else since. I had to sit at the dealership in Moristown until my sister could drive from Lexington KY to take me home. I have severe walking impediment due to broken neck from a car wreck. This whole experience was terrifying.

Heading to work on hwy 140, there is no trees nothing that could fall on my car the nearest car was at least half a mile away, it's 30something degrees outside and as my driving I heard a loud boom I opened up the cover to my sunroof and it was shattered, there's nothing that could have landed on it the glass was pointing upwards like it exploded out. That stretch of road I was on has nothing around that could cause that and if it had been a rock it would have hit either the front of my car or my windshield and neither were hit or anything of that nature. The only conclusion I have is that it was the temperature difference.
