Hello everyone,
Took my '19 3500 in for a bad track bar and windshield wiper problem. When I picked it up, the Service coordinator told me the Flashed the ECM/PCM per TSB 18-010-21 rev B. So first, I was having Zero problems or codes that the TSB indicates would require a flash. So far, ( Only drove it home in traffic, will drive it to work today) it shudders on acceleration. I am going to call them today but wonder if any of you have had issues, or if the dealer can flash an ECM without permission? I have no tunes or anything, I just dont like my truck to run worse after some one else touches it.
Thanks!
