NHTSA Complaint #11509616 — 2016 KIA SOUL

I have been having issues with oil consumption since early fall 2022. I am the sole owner of my Kia Soul Plus and have had multiple oil consumption tests performed. I found out I had an oil consumption problem when my car shut off WITHOUT WARNING on the highway. Luckily this happened around midnight when there wasn't a lot of traffic. I contacted the dealer and they did an oil consumption test, which it "passed" because the dipstick indicated there was still oil in the engine. After the first one, I started to monitor my car and it seems like a little past the 1k mark does the dipstick indicate there's no oil. I've done like 3 tests with the dealer, and I think the last one that was performed I think they put too much oil in it. I say this because when I checked the oil -- when the car sat for awhile to cool off-- there was oil past the fill line on the dipstick. When I asked about it, they made it seem like I invalidated the test because I simply checked the oil. I was also told to not check the oil when the car has been sitting. So now, I check it at different times; when it has and has not been sitting (when I get gas). What ended up happening was the guy just read the dipstick right there in front of me, said it was fine, topped of the oil and said I was good to go. I think they did this the second time as well but didn't think to check the oil level then. I also noticed oil stains/residue on my engine cover and asked the dealer about it, but received no answer. It seems like the oil stains are getting worse -- more prominent. My car currently has 92k miles on it and have been trying to figure out the issue as this is a HUGE safety issue to me and my family. On multiple occasions I have found that my car has had low oil in it and carry oil in the back of my car just in case. After doing research, I'm glad to see I'm not alone but also that this is a known issue but I feel like the dealer is waiting for my warranty to expire before anything gets taken seriously.
