2018 RAM 2500

Abs module, hcu module currently available to be inspected if dealer won’t fix. Potential loss of brakes. Dealer confirmed i had codes relating to a known problem with both abs and hcu modules. Dealership ran diagnostics. Service braking system warning lamp appeared on dash. Codes C0020 and U0147. Fca star letter case #: s2005000004 letter relates to codes stating general electrical failure. Dealership wants to charge me $785.21 to fix. They started by saying the cost would be close to $2800, when i asked why so much, they said i need several other repairs but couldn’t provide a break down. I brought my vehicle in with the letter about the faulty equipment and the codes and was told it would get taken care of.
