2015 Kia Soul: adaptive cruise control problems

Filed Jun 25, 2026 · KY

My engine light came on about 6 months ago because I was smelling a gas. I had it run on a code computer and it just showed a gasket needed changed. I didn't think that that was serious enough to address urgently because was unsure how much the cost would be. But was going over a big mountain about a week ago and car was on cruise control at 55 Mpr and all of a sudden it just started dropping down totally stopping on me in very active traffic had my grandchild in the car also, got off the road barely in ongoing traffic and called for roadside assistance, but my son showed up and got it to start I barely got it back to his house in Rogersville tn. Where I was staying for a visit , I Ran a code computer on it again and it said it was the Cadillac converter, I looked it up and there is a recall on this situation. Why your sight is saying it's 0 idk why. This is my report and I think u need to change that problem there . I am currently still at my sons house staying cause I can't get my car home cause it won't climb clinch mountain or any sharp hills. Thank you

When using cruise control, car will randomly speed up or slow down and get very loud and also jerk forward. It will also occasionally jerk forward or backwards while driving normally.

I was going 65 MPH, with my cruise control on, while it was raining. I hit some standing water, which caused me to hydroplane. I could not gain control of my vehicle, so I ended up spinning and hitting a concrete barrier. None of my airbags deployed. Thankfully I wasn't seriously injured, but the airbags should have deployed either way.

1. I experienced this twice now. Driving down an ally the vehicle turned off on me. The second time I was parked ran into my house came out and it was off. Luckily I wasn't on the highway at the time of this happening. Also in somehow lock my keys in the vehicle when I came out to grab something from the trunk . 2. You'd think a 2015 vehicle wouldn't let you do that especially with the keyless entry. 3. Also I'm noticing a vibration in the idle when sitting parked with the engine on. 4. While in cruise control I noticed that the car does not stay at a consistent speed especially going up and down hills. The vehicle loses speed within a 10 to 20 mile per hour range.
