NHTSA Complaint #11650356 — 2018 NISSAN VERSA

Has an issue with the mass flow air sensor. I had this car for 7 months with 84,000 miles on it and noticed instantly that it had poor mileage and stalled a lot. Check engine came on the first time and I took it to have a diagnostic test and a P101 code came on, a couple of days later the car wouldn't start. Replaced the mass flow air sensor and the car was driveable but it had the same poor gas mileage and stalling that it did the first time. Went out again within a week for the 2nd time. Got it replaced recently a third time and Im still having acceleration, poor gas mileage, and stalling. Car isn't safe to drive and does not pass the smog test .
