NHTSA Complaint #11574809 — 2017 HYUNDAI SANTA FE

My wife was driving down the freeway to work during morning commute when her 2017 Santa Fe just lost power, was only able to go maybe 20mph which during an early morning Bay Area commute is very dangerous... No engine light or any warning lights, this lasted for a couple miles until the next exit she pulled off still no warning indicators showing, she turned off the car for a few minutes, then turned it back on to continue to work there was still almost no power but no indicators on the dash, finally after a few minutes started driving normal again. The next day when she was on her way to work, she started getting an oil light, I drove 45min to her job checked and oil level was fine, turns out oil pressure sensor was bad. After that was replaced everything seemed normal for around 1month or so then noticed excessive oil consumption, needing to add 1qt every 1500-2000 mi, no oil leaking onto out driveway and can't see any oil leaks visually around engine. Oil consumption has gotten progressively worse, we keep it topped off every couple weeks. No we are getting check engine light and tapping sound on passenger side of engine. Codes P0346, P0021 and P0087, power is fine but tapping sounds bad and worried of failure while driving.
