NHTSA Complaint #11628585 — 2019 INFINITI QX50

Turbo, Rear-Coupler, Engine, Actuator Car was squealing and I was told that the serpentine belt needed to be replaced. Replaced this. Car still squealing and took it back. They replaced the belt, again.. Still squealing, now I am told its the tensioner that needs to be replaced but only Infiniti can do this (belt done at Firestone). At Infiniti - they look at the car and the tensioner is fine. But my turbo is blown. How? So, they replace the turbo and then say the rear coupler needs to be replaced. Repairs done and Infiniti said all fluids are good, everything is great. However, I might see slight smoke and a burning smell for 100-150 miles as theres a thin layer of oil on the turbo that will burn off. Oil change isnt due for 5k miles and I checked before my short road trip - all is good. Past the 100-150 miles and the car is SMOKING and SMELLS OF BURNING... Call infiniti, this is normal it will go away. Check fluids again, as no lights on the dashboard and oil is fine. Come back to get my car, check the ground as I always do and no oil/fluid and proceed home. 10 mins from my house the car WREAKS of burning smell, will not accelerate, no dashboard lights. So, I sit there and let it cool down - check again everything looks good. Try again, car will not go. Fluids look fine - oil, no spikes in temp, and no lights. Next day, no fluids under the car. Car accelerates but lunges me then stops going. Car smells bad, smoke.. go to check the fluids and NO OIL in the car out of no where. Infiniti tows it and it sounded like it was going to blow up. Also, a tink tink tink sound started out of no where. This is dangerous as the vehicle could had started on fire. I still dont know what is going on as Inf. has the car right now. This is a major safety hazard as I found a LOT of reports on this happening to others with this specific model and year. I had NO issues like this until Inf replaced the turbo.. NONE!
