They are replacing the ECM in mine now.

Update on my 2020 trailboss I bought 5 months ago. Failed to start right after I bought it and they replaced the fuel pump module. It now happened again 5 months later. The first time 275 miles on it and now 13000 on it.

So far 1200 miles since they changed out the fuel pump module in my new TB and no issues. Not a lot of miles, but at least it's better than the 200 it made it the first time.

I just received my truck back and they replaced the fuel control module. Hopefully it holds up.

I had the same issue on 2020 LT trail boss 6.2 less than 200 miles on it. I drove it home from the dealership and the next morning it wouldn't start. They hauled it back and replaced the fuel control module. I just got it back so we will see how it holds up.

2020 trail boss 6.2 175 miles on it. I just drove it home from the dealer and it wouldn't run the next day. They hauled it back to the dealer yesterday and waiting to hear the results.
