Front Seat Power Adjust problems of the 2020 Nissan Rogue

I purchased a 2020 Nissan Rogue sv that has a power adjustable drivers set. The slide rail assembly has play in it when adjusted to my driving position. It rocks back during acceleration and rocks forward during breaking. I can sit in the seat stationary and move it forward and backward with my body weight. The service manager at the dealership tested several other 2020 models and found 3 others with the same issue. One of them rocked back and forth even worse than mine. I contacted Nissan consumer affairs and was told by the representative that their internal review was " this is a natural occurrence of the manufacturing process. " I owned a 2017 Rogue with the same seat. There was never any play or movement with the drivers seat. My concerns are that if upon impact either front crash or being hit from the rear, this movement in the seat could possibly result in the seat breaking free due to the improper gap between the slide rail assembly pieces. It is also a severe distraction to me as the driver. Distracted driving should be taken seriously in this matter. My last concern is this. How many of these faulty power seats are out on the roads already? I don't want to see a single person caused harm during a crash. Please investigate these power seats from Nissan immediately. Safety must always come first. Thank you so very much.
