NHTSA Complaint #11676501 — 2020 HYUNDAI SANTA FE

First noticed during the last 3 months that the car seemed under powered during acceleration. Then had 2 incidents where the engine shut off when stopped at intersection to turn. Then on [XXX] I noticed while driving, the oil warning light flashed but did not remain on. Then again it flashed 1 time and did not remain lit. Upon checking the oil I found it to be 3 1/2 quarts low. Oil had been changed at the dealership at 90000 miles and the mileage that day was 93340 miles. No leaks under the car where I park at home or work. Have had all our regular oil changes at the dealership every 5000 miles. No prior oil consumption noted. We have contacted the dealership.
