2020 Infiniti QX60

I was driving to work and then the vehicle stopped working once I reached a red light. It would not start and had a burning smell with smoke coming out. I had to call the police which they deemed undrivable and not safe. The car said battery but upon inspection it was a starter and possible belt problem. I've only had this car for less than three months and did an initial inspection where everything was deemed good. Now the car has not shown any problems and had an oil change for basic militance. I had no indications what so ever. It is currently being inspected by the dealer but I have heard back. I do know however, The towing company had tried to turn it back on and it was unsuccessful in both attempts. They had to forcefully tow the car which left tire marks.

In the summer of 2022 (I think Aug) car was stalling when stopped to make a turn. The check engine light flashed but never stayed on after the 1st incident. Brought it to a dealer and was told that the car was fine. Drove it for another two weeks and the same thing happened and no warning lights appeared. Brought it back to the dealer and was diagnosed with faulty fuel injectors after this 2nd visit. I believe all of the fuel injectors were replaced. In May of 2023 car sounded as if it was going to stall again when stopped in traffic. Happened again in early July and again last week. Today, when I was driving the car sounded as if it was going to stall/jerking. No warning lights came on in any of these scenarios. Todays incident is very concerning since this happened while I was driving between 40-50mph. Since May I have brought this car to two different dealers 3x and they can’t find anything wrong. Safety issues when idling and now when driving. It’s not a consistent issue and is unpredictable, which makes it even more concerning. I called a dealer today and was told not to bring it in since no warning lights came on and they already checked the car about two weeks ago. Was advised to drive the car in sport mode for a week to see if this makes a difference. I do a lot of driving and I’m afraid to be on major highways and driving late at night. I now have to make sure that I drive in a lane that has a shoulder in case I need to pull over.
