2018 RAM 3500 Complaints

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the "ABS System Fault” message was displayed. The vehicle was taken to the dealer, who diagnosed failures with the ABS control module and ABS pump. The vehicle was repaired, but the failure reoccurred 7-months later. The vehicle was taken back to the dealer and was diagnosed with ABS control module and ABS pump failures. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the dealer and it was determined that the ABS control module and ABS pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 9,000.

ABS AND TRACTION CONTROL LIGHTS ON DUE TO FAILURE OF ABS MODULE AND PUMP. NO ACCIDENT BUT FEEL THERE COULD BE A PROBLEM IN THE FUTURE CONSIDERING THIS IS A SAFETY ISSUE

Service and systems and service electronics brake system warnings at approx 50000 miles. Dealer is saying it is an HCU failure

The Anti-lock Braking System module and the Hydraulic Control Unit originally equipped on 2018 Dodge Ram 3500. Vehicle is available for inspection upon request. Problem has been identified in 2020 by dealership upon delivery when issue first presented itself, and fixed by dealership. Issue came back in January 2023. I took the vehicle to an independent mechanic and the module was sent to have fixed. When the part was sent back after repair, the problem wasn't fixed. There were no known issues prior to the failure.

The ABS warning light illuminates, and warning chimes continually go off as I drive. I've been literally waiting years for a fix (since 2020). The dealer says the parts are unavailable. In the meantime, I intermittently have no ABS, cruise control, or trailer brakes. This is concerning because I tow a heavy trailer. It is very easy to lose control if you're not careful.

The ABS systems constantly shuts down, causing the Traction Control system to shut down. When I recently went on a trip towing my trailer I needed to stop on a downhill wet incline. When I first applied the brakes the system was working properly but failed during my stop and it caused a significant steering issue as I had to now react differently. This is a safety concern and RAM knows about it. I am paying for a vehicle that is unsafe to drive in less than perfect conditions. Very dissatisfied with RAM

ABS light started flashing and cruse control quit working. Scanned for codes and found P0020-01 ABS control module. Searched online and found 1000's of cases of problems related to this.

ABS failure light started coming on along with service electronic brake system. Dealer shows I believe code 0020 which is the ABS/HUC pump failure. Dealer says seeing it quite often, hard to get parts as each part is allocated and tested before leaving. So I either stop driving it and wait for parts which seems to be a known issue or keep driving and hope for the best while the engineers try to figure out what is going on. Currently it is sitting at the dealer as they try to get the part before we leave on a trip at the end of the month.

ABS,brake system came on first time on or about july 8th or so,in bad weather, hard rain had to come to sudden stop and lost control wheels locked up. But no harm done just nerves Dealer said bad control unit antilock brake system and replaced hydraulic brake part at 18386 miles, all good since. now its back same thing now there is 32210 miles on truck and same thing now ,abs brake system. Trackion control They said internal failure of unit the first time . Now we have to start all over again with the risk of braking safety at 32210 miles on Ram

the following messages appear randomly and frequently resulting in a dash lamp/ chime and loss of cruise control electronic braking system fault. HCU electronic error (stored code) many reports of the same problem I've read about.
