Hello all, hoping to get some help on an issue going on with my 2018 maxima. When at a stop, then going into acceleration there is an almost mechanical grinding noise, that last from 1 to 2 seconds and happens a couple times from the front on the car. It only happens up to 35mph then will not happen again. Transmission comes to mind but the fluids and transmission were just checked at my local nissan dealer 400 miles ago.... Just very loud and sounds horrible for a car with only 30,000 miles. Any info would be greatly appreciated seeing I've only had the car a year and can't find any info on the issue I'm having. Thank you for your time!
