Timing Tensioner Problems of Infiniti Q50

The serpentine belt makes consistent noise in all types of weather. Already had the dealer replace it once. Noise came back and the dealer now says it could be the tensioner pulley.

I have a Infiniti Q50s redsport 2017 actually have 34000 miles in the odometer. This car have a factory defect that involves engine parts in this case serpentine belt, belt tensioner and pulleys. There is a TSB at this time for this issue but in the majority of cases the cars still showing up the issue. Major issue at this time is that serpentine belt brokes while car is on move. The car needs to be stoppend since engine overheat and also baterry light goes on. The belt tensioner get stuck and pulleys in some of the cases melt down. In my case my car has visited 2 times with the same issue. There is a TSB that pretend to fix that issue realigning the ac compressor. At this time there is few houndreds maybee more cara affected. I think this is a major issue since the serpentine belt broke and engine stop being functional due overheating. This can cause a major accident or other security problem.
