2021 RAM 3500 Service Brakes Problems

Brake system is not functioning as designed. Rear axle braking is not being fully applied and is most noticeable and concerning during heavy haul usage. Vehicle has to be operated carefully and with an alternate braking method utilized to obtain adequate braking. The problem can be and has been reproduced and verified by dealer but not in writing. Dealer is not wanting to fully diagnose and/or commit to finding/acknowledging a fault. Manufacturer has been notified in writing and unresponsive. There are no messages displayed/stored. Disproportionate brake wear between front and rear axle braking is observed.

See attached document for complaint.

Vehicle died in a busy intersection coming off the freeway. Light flashed that indicated it was an issue with the electronic throttle control. The safety of myself and others was put at risk due to the posted speed of the road and multiple lanes from 4 directions. I had to remain in my vehicle to make sure I was not hit by another vehicle and due to the vehicle issue, I was impeding traffic. Lithia Dodge of Grants Pass, OR stated they could not make an appt for the vehicle to get looked at for 2 weeks out, scheduled 8/22/25. Dealership seems to think this is not an issue with safety and this issue can occur while the vehicle is in motion which is a huge safety issue. No warning lights flashed before the first one indicating the vehicle would shut down/lose all power.

I powered on the truck. Upon ignition check engine light, along with ABS, 4WD, traction control came on. Lights for the forward collision and adaptive cruise control illuminated. ABS system in the truck is no longer functioning causing the brake pedal to pulsate and lose pressure. Dealer diagnosed the troubleshooting codes and determined the ABS and the HCU (Hydraulic Control Unit) need to be replaced.

Brakes started grinding at 13,000 miles. Determined they were metal to metal, caliper, overheated, excessively, and rotor needed replaced. Problem happened again now, at 22,000 miles.
