NHTSA Complaint #11711301 — 2016 GMC TERRAIN

I bought the vehicle in November of 2025. No warning lights or problems running. Check the engine oil upon purchase and have the dealership sticker showing oil change was recently done and oil showed that it was full. Approximately 3 weeks after purchasing, the car starting idling rough and stalled a few times during my commute to work. The check engine light came on and it showed that the vvt was a possible solution for the code P0014 this was on December 12th 2025. I replaced the suspected part with no change in vehicle condition. I checked the oil and found that it was empty/no oil on dipstick. I had to add 5 quarts of oil and then it showed it was in the safe zone on the dip stick. Today (January 15th 2026) I checked the oil again and it showed no oil on the dipstick. I had to add 2 quarts for it to be at the bottom of the safe zone on the dipstick.
