NHTSA Complaint #11548542 — 2016 KIA SEDONA

We were driving with FIVE kids and my 2016 Sedona lost power while driving & wouldn't accelerate over 30mph. Drove home couldn't go over 30 mph even with the pedal to the floor. Got home, checked oil and it was bone dry. Check engine light NEVER came on and the oil light NEVER came on. The check engine light only came on AFTER it lost power and went into limp mode. Oil was not leaking as I park on a concrete driveway and would have seen any leaks immediately. $2,000 later at the mechanic (they replaced value covers and sensors) and the check engine light still wouldn't go off and the car continued to lose power after driving for about 20-30 minutes. I can turn the car off, wait a few minutes, turn it back on and it runs FINE for a while (20 mins. max). Also, the car runs absolutely fine until it loses power. No noises, no knocking, nothing to indicate there is an engine issue. The mechanic who couldn't fix it recommended; I take it to the dealer for a complete diagnostic workup. After a week at the Kia dealer with little to no feedback / info as to what was going on, I was finally given an estimate for $7,800 worth of repairs and told that still may not fix the issue as there could be internal engine failure because it ran out of oil. After a cursory google search, this appears to be a common problem with the Kia 3.3 GDI engines like mine. There were recalls and Kia extended the engine warranties on various other models with the same engines due to the exact same issue, but they have not extended the same benefits to Kia Sedona owners. There was even a class action lawsuit regarding this issue but again, not with the Sedona. My concern is this is a MAJOR safety issue. FIVE kids in the car on a normally busy highway (it was early so there weren't many people on the road). Had it been as busy as it normally is, we would have been rear-ended which could lead to MUCH worse on a busy highway. Please investigate this before someone is seriously hurt or killed.
