Anyone lost their fuel gauge instrumentation or heard of an ECM update?

Recommended Posts

My 2020 GMC 2500HD fuel gauge suddenly dropped to zero the other day and the range indicator had - - - displayed. I took it to the stealership and it fixed itself along the way with no error codes. The stealer says there is an ECM update that *may* also fix this. Anyone heard of that? I think they are BSing me here.

 

They are also replacing the rear Bose speakers and fixing the seatbelt retractor which is broken and falls off and a few other stupid things.

Last time I took mine in for water intrusion they said there was a service bulletin related to fuel gauge. Don’t recall which on it was.

Dealer told me there is no fix, come pick up the truck. I would rather ditch it on them and say if you cannot even guarantee that my fuel level is accurate....I swear. GM.
