2020 Infiniti QX60

2020 infinity qx 60 Bought car used in 2024 with 80,000. There is a hesitation when accelerating and sometimes seems to want to die when idling. There is also a knocking sound at times when accelerating. At times I feel transmission skips. When turning right or left or reversing, the wheels seem to creek and almost grind a bit. I am great about maintenance and called to determine if my vin was included in the current recalls. I am told no, but am experiencing the same symptoms described by infinity. Just want to know if there is a any action to take to ensure my 4 kids and I are always safe when traveling and dont end up with thousands in repairs.

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.
