Cruise Control problems of the 2015 Kia Motor Soul

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.

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.

A couple of months ago the car said we have a problem with the engine and with the cooling system kia had check it out and said nothing was wrong but it keeps going on it has a gas smell low push to do 70 on highway won't let me put on cruise control for long I can feel car ready to shake and stop needs oil all the time when I drive for 1 hr to work car starts to shake at a red light after I'm almost at work I changed battery on 3/10/19 I also changed the catalytic converters also brakes always have to change before there do on 3/15/19 have an appointment to change the flex on the car also because the oil was leaking on the engine it needed a seal and the top part I forgot what it's called replaced that's all I now for now.
