In 2021 I bought my ram 2500 had problems since day one. Started with when coming to a stop truck would start rough idle and surging while at a stop light with foot on brake and would often just off when rough idle would happen. Had computer changed still does it to this day took to dealer several times. Then I started hearing a grinding noise and noise would change when turning steering wheel and sometimes it would just randomly just stop making the noise. They said they couldn’t find a problem. At 43000 miles my truck wouldn’t start jumped it and worked for a week then again. After that had to jump every time so got a new battery. After installing new battery a few weeks later dead again. So tested battery it was good. Pulled out starter power supply nut was hand tight so fixed that figured dealer knew as much as I did. Now I have a rough idle and ticking after it warms up
