I lost trailer brakes, hydraulic controller not working. traction control light is on along with my airbag and my abs light comes on at times. NO REPAIRS WERE DONE YET. DEALER STATES ORC MODULE NEEDS REPLACEMENT. I believe this is an reoccurring issue.
Recurring water intrusion through firewall/wiper cowl causes electrical corrosion and loss of vehicle communication (CAN bus). Dealer repeatedly documented: • 05/19/2022: “Cowl drains clogged; water entering passenger side” (Invoice #XXX). • 08/15/2025: “Water intrusion through firewall due to wiper cowl drains being clogged with organic debris; water found in passenger kick-panel connector” (Invoice #XXX). Resulting failures include: • BCM shorted (02/16/2022 – replaced). • HVAC module failure (10/15/2022 – replaced). • Intermittent CAN bus, loss of gauges while driving (09/04/2025 – Invoice #XXX; dealer suspects internal corrosion from prior water leaks). • 10/16/2025: Dealer states “old water damage to BCM causing corrosion on circuit board and disrupting bus circuits”; BCM replaced again (Invoice #XXX). • 10/20/2025 (current): Dealer states “ORC (airbag module) dead on bus; ABS module loss-comm with ORC; replace airbag module” (Workorder #XXX). The truck has lost instrumentation and safety systems in rain, with airbag and ABS communication currently inoperative. This is a safety defect; seeking investigation and manufacturer remedy/reimbursement. Injuries/Crashes: None, near-miss due to loss of gauges. Dealer: Hall Chrysler Dodge Jeep Ram, [XXX] .

The contact owns a 2019 Ram 3500. The contact stated that while attempting to park the vehicle, the electronic parking brake was engaged, and the vehicle inadvertently shut off and failed to restart. The dealer was contacted and confirmed that the failure was a known failure. The dealer advised the contact to disengage the electronic parking brake to restart the vehicle. The contact stated that he followed the instruction of the dealer, and the vehicle restarted; however, the check engine warning light and other unknown warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed that a secondary lever chafed the electrical wiring underneath the dashboard and caused the vehicle to shut off when the electronic parking brake was engaged. The dealer informed the contact that the dashboard needed to be disassembled to secure the electrical wiring. The vehicle was not repaired. The manufacturer was notified of the failure and a case was filed; however, no additional assistance was provided. The failure mileage was approximately 63,000.
When truck is in cruise control on with driver assist on, if I run off side of road and go over the ridges on the side that alert driver my ABS light comes on saying my driver assist and my cruise control can no longer be used and my ABS breaking system requires a mechanic. If I reset my system all goes back to normal till I go over rough road or ridges. I have less than 10,000 miles on truck. From what I hear from other Dodge owners this is a common occurrence. This has happened on three different occasions.
The contact owns a 2019 Ram 3500. The contact stated that on various occasions and while driving at various speeds with a trailer attached, the brake pedal was depressed; however, the trailer brakes failed to respond. No warning lights were illuminated. The vehicle was taken to two independent mechanics, where the failures could not be duplicated. The failure recurred. The vehicle was taken to a local dealer, where it was diagnosed that the electronic trailer brake controller needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The approximate failure mileage was 20,000.
Last week this took place: 2019 Ram 3500 Dual rear wheels AISON transmistion is outfitted with factory trailer brake module. Was hauling a horse trailer near 30,000 lbs to a horse show, caravaning with crew pulling a second horse trailer about the same weight with a 2020 Ram 3500 (Vin #3C63RRNL7LG242818 (see separate complaint)) . All connections checked before departure. ABS warning light went on a few days before then disappeared. When braking, no trailer brakes engaged. Then checked hand paddles on the factory trailer brake module and the hand paddles activated the trailer brakes. Took it into the dealership to check codes and they said none appeared or were somehow reset.
MY ABS ON MY BRAKES KEEP GOING OUT ON MY TRUCK AND I HAVE 2 2019 RAM TRUCKS AND IT DID IT ON BOTH OF THEM AND I HAVE SOME FRIENDS THAT HAVE 2019 AND 2020 RAMS THAT'S DOING THE SAME THING SHOULD IT BE A RECALL ON THIS BEFORE SOMEONE GET KILL?

MY TRUCK IS EQUIPPED WITH A DEFECTIVE CP4 INJECTION PUMP. IT'S BEEN CHANGED TWICE SINCE MY TRUCK WAS BUILT, ONCE IN 2020 AND AGAIN IN 2021 TO A DIFFERENT MODEL. RAM HAS HAD MANY COSTLY AND DANGEROUS FAILURES WITH THESE PUMPS. I HAVE NOT YET HAD A FAILURE. HOWEVER IT'S ONLY A MATTER OF TIME. WHEN A PUMP FAILS IT HAPPENS SUDDENLY AND NOT ONLY DOES IT WIPE OUT THE ENTIRE FUEL SYSTEM AND SOMETIMES THE ENGINE, IT CAUSES YOUR ENGINE TO STALL. THIS CAUSES LACK OF POWER STEERING AND NO BRAKES. MY 3500 IS BUILT TO TOW HEAVY TRAILERS AND IN A SITUATION WITH HEAVY TRAFFIC OF A STEEP GRADE SUDDEN LOSE OF BRAKES COULD BE DISASTROUS, ESPECIALLY TOWING A CAMPER WITH MY FAMILY ABOARD. RAM KNOWS OF THIS PROBLEM AND MADE A QUICK REVISION OF THE PUMP IN 2020 AND DITCHED IT ALTOGETHER IN 2021 FOR A DIFFERENT PUMP. THERE NEEDS TO BE A RECALL ON THESE 2019 FIRST MODEL TRUCKS WITH THE KNOWN DEFECTIVE AND DANGEROUS CP4 INJECTION PUMP.
RED HYDRAULIC FLUID IN BRAKE SYSTEM CAUSE BRAKE FAILURE, WHICH CAUSE ME TO CAUSE MINOR DAMAGE TO A BRAKE LINE. DEALER HAS HAD VEHICLE FOR OVER 2 MONTHS, CLAIM VEHICLE DOESN'T QUALIFY FOR RECALL THAT STATES SIMILAR ISSUES AS V98 WHICH IS FOR 2019 DODGE RAM 3500S , ALSO SAYS PARTS ARE ON RESTRICTIONS DO TO RECALL AND CAN NOT REPAIR MY VEHICLE DO TO THIS.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
