After reading in my instructions Manuel about what might be causing my fuel consumption to be way to high I learned that the gas cap was suppose to click which it has not since we got the vehicle in December of 2021so I went and bought a gas cap and now it clicks like it's suppose to. My fuel consumption is way to high right now I have filled this car up with gas so many more times then any other vehicle I have owned. When I put fuel in you can smell the fuel for the next two days and every now and again you get a whiff of engine coolant smell and a burning smell I'm not sure what the burning smell is because I've never smelled it before. Yes the vehicle is available for inspection. No one has inspected it still since my last complaint. And no there has been not a single warning light.
The contact owns a 2015 Kia Soul. The contact stated that while operating the vehicle the braking system was erroneously activated, causing the brakes to engage without the brake pedal being depressed. Additionally, while driving at various speeds, the vehicle would drift to the right. The contact stated that there was also an abnormal odor of fuel present inside the cabin of the vehicle. The vehicle was taken to an independent mechanic who was unable to determine the cause of the failure. The manufacturer was notified of the failures and referred the contact to the local dealer. The local dealer was not yet contacted. The failure mileage was 32,000.
Leasing a 2015 Kia Soul + from Weston Kia in Portland, Or. on 9/1/20 with 94,191 miles on it. I've had routine oil changes done on 12/14/20 @ 99,961 miles & again on 3/8/21 @ 104,432. Now from about 1-2 months after leasing my Kia, the MIL would turn on for some time then go off just to turn back on again. I had an ASE certified mechanic where I work run a diagnostic Check on it with a code of P0014. Called Weston Kia service department about it and I was told that I would have to bring it in to them, charge me $139 to run their diagnostic check to see what's up! Now On 1/25/21 I received a letter from Kia about a safety recall, #20V750 for my Kia, after 3 months I was finally able to get it in for the recall service. …
I have a complaint about my 2015 Kia Soul car service issue. Since I purchased the car in December 2021, my check engine and oil indicator light has been on. I took my car to a car repair shop, and was told that the engine oil is being sucked into the exhaust system and to take my car to a Kia dealership. I scheduled a service appointment on 07/14/2021 and paid about $145.00 for a diagnostic system check. I was told that my catalytic converter is blocked and the cost to replace the catalytic converter and labor would be about $2,000. I would have to pay another $145.00 for another diagnostic system check about the engine oil issue. The overall car issue is that the engine oil is going into the exhaust system and causing blockage in the catalytic converter. …
My catalytic converter failed just under 4 years after getting the SC176 recall done in July 2020. I believe it's possible there was a step missed in the replacement of my catalytic converter related to the recall, specifically the Catalytic Overheating Protection Engine Control Unit logic that may have caused the converter to fail. I do not detect that on the attached receipt from the repair that was done for the recall. Although there were no safety issues that happened, after reading the recall and what can happen as a result of the catalytic converter failing, I am concerned for my safety if I drive it any longer in that condition. The problem has been diagnosed by my local Kia dealership on Friday 4/19/24 and that is where the car is presently. I have attached the inspection report and the cost to fix it. The vehicle has not been inspected by anyone other the Kia dealership. …

I was driving my 2015 Kia Soul along a 4 lane highway when the Check Engine light came on and begun to flash. The Kia began to lose about 5 mph off and then return to the previous rate of speed a few minutes later. Then it would repeat the cycle. As the vehicle lost the engine power, the steering also became very tight as if the power steering was also malfunctioning. I could also hear a slight tapping sound, as the driver side window was open just a few inches. Since I had my mother whom is ailing with dementia and heart problems, I tried to remain calm and undisturbed by these issues. As soon as I arrived at the closest auto parts store that offered diagnostic readings (O'Reilys), I asked them to see what codes the vehicle was throwing. The codes were P0420 Catalyst System Efficiency Below Threshold (Bank 1) and P1326 Knock Signal Range/Performance. …
While my 80 yr old dad and 18 yr old daughter were driving on the highway to get to my uncle's funeral. My dad had his cruise on, when he and my daughter started noticing a strange sound almost a knocking sound. But the next hill when the car went to go up the incline it kept reducing in speed. My dad took the cruise off and at that point had no power to keep traveling. So August 2nd the car threw a rod. My dad had a warranty plus an extended warranty with the company GWC. They missed my uncle funeral, sat on the side of the highway for an hour before the tow truck got there. A local dodge dealership has gotten the vehicle and have done a complete inspection. The safety of my dad and daughter were at risk do to the car malfunctioning on the highway. As well as them sitting on the side of highway. …
I bought this vehicle new (under 3k miles) from the dealer Kiefer Kia. The very next day I brought the car back as there were obvious problems with it immediately. The car would hesitate, almost as if it were about to die, while driving or even sitting at a light. When I took it in the repair person heard the problem but said "that's normal for a new car". I wanted to reopen the car but they said there were no returns. I came in 2 other times. On the 4th time they finally replaced the computer. It did nothing to fix the problem but from that time I had electrical problems. They denied the electrical problems. 2 more visits they replaced the computer again and some other recall. Both problems continued. I've had to replace the battery more than once a year. …
My engine has had many issues stemming from a bad engine Kia of Irvine has avoided fixing they have charged for fixes under warranty and ignored code p0420 since 2018. After much push Catalytic engine was replaced replaced in 2021.
