Abs and traction control lights come on and off dealership replaced the hcu and the problem stopped. 2 years later and only 3,000 problem started again. Contacted the dealership and they said its a known issue but no parts are available and no recall

The ABS module and associated control unit have failed. This causes the anti lock braking and traction control systems to be inoperable which can cause the vehicle to lose control which can cause injury or death. FCA is aware that these units are defective and refuses to fix them.

Message comes up to "Service electronic braking system." Code found was C0020-01 (ABS pump motor failure). Couldn't order part due to engineering review. Truck only has 20,400 miles. This part cannot be worn out. Should be a safety recall.

ABS Module and HCU Failure. No ABS or Traction control which could cause the driver to lose control of the vehicle. There have been several complaints filed but no recall issued.

Driving, hit 40,5xx miles and ABS and traction control light was flickering on and off. Kept getting warnings to service ABS and Electronic Brake System. After 25 miles of on and off flickering and chimes which were extremely distracting, it turned on and stayed on permanently. I do not have ABS, Traction control or cruise control. This is a known issue with the 2017/2018 models, and Mopar does not cover it even though it should be a recall. Thousands of people are having this issue, and dumping thousands into it all for it to just break again in 10/20k miles. The ABS modules are complete junk

ABS Module Failure. Truck is available for inspection upon request. The ABS Module Failure directly effects the safety of all occupants and other vehicles on the road if not able to stop as intended to. The problem is confirmed by a dealer. There were no warning lamps until the ABS Module failed and needs to be replaced. This is a standard issue that needs to be recalled.

The abs and traction control lights stay illuminated on dash. No abs, traction control, or cruise control. Abs module looks to be the problem

ABS light and Tracking control lights flicker on and off constantly. No warnings just came on one day. I have 38,000 miles on my truck not very many for warning lights to come on. I cannot use cruise control as well as about half of my controls. Including tracking control which is now permanently off and is a major hazard! Took it to the dealership in Concord, CA and was told the control module is bad. With no time frame to fix. Probably will be a fix once my warranty is up so the dealership is not liable to fix my truck. A quick search online shows this is a problem for this vehicle.

ABS lights flash on the dash, electronic braking system fault, traction control flashing. Intermittent. Research shows replacing HCU will resolve, I will order the part and repair myself but this should be a covered recall since it is a safety concern.

ABS, TRACTION CONTROL, REPAIR ELECTRONIC BRAKE ALERTS HAVE BEEN FLASHING WITH AUDIBLE BEEPING AND AT TIMES REMAINS LIT WITHOUT BEEPING. Putting a load on the engine or hitting bumps on road seems to cause the warning lights and beeping. This has been going on since June of 2022. Vehicle was taken to shop and diagnosed with failing part (electronic abs brake module) Part was not readily available and waited two months for part for repair. Cost $525.00 total. Did not fix problem now repair shop states the truck needs HCU hydraulic brake fluid pump. Its been EIGHT MONTHS no part available. Truck is in need of repair, no parts available and has limited our use of airstream tow vehicle for travel.

Service ABS and electrical brake system failure lights come on randomly and repeatedly. This also disengages the cruise control when it happens. Sometimes the warning light stays on for a few minutes, other times it flashes on and off and dings each time. This is a very common issue for this year of Ram truck from people that I know and from the research I have done. At my previous employer, we had 2 other rams the same year with the same issue. The ABS system will not work with this problem - I was driving and my vehicle skid due to there not being ABS. I have tried on multiple occasions since my truck had about 85k miles on it to get this problem repair. The dealerships all told me they dont have the parts for a repair

This complaint is based on the repeated failure of the vehicle's ABS/Traction control system and the lack of a repair solution from Ram. The failure starts as an infrequent (once per trip or so) fault and immediate clear of the ABS system with an audible alarm and dashboard message. Over the course of a few hundred miles the problem worsens to the point where it it faulting as often as every 1-1/2 to 2 seconds. (It is like driving with the seatbelt warning going off). Sometimes it will stay faulted or cleared for several seconds to minutes at a time. In the beginning of the failure process it seemed to go away once the engine got fully warm, after about 10 minutes of driving. This problem was diagnosed and repaired at a diesel specialty garage with replacement of the ABS Control Module and Electric Stability Control Unit. Reprogramming was performed by a Ram Technician. After about 7000 miles the problem returned, following the same failure pattern. The same shop inspected and and repaired a loose connector, another known deficiency in the system. However, this didn't fix the issue. The alarm started before I moved the vehicle (after paying for the repair). At that point I was told that there was no solution, and in fact there were four other trucks there with the same issue. The parts are under warranty but I am left paying for labor to install equipment that seems will fail fairly shortly. And I am left with a completely unreliable ABS system. The failure doesnt seem dependant on speed, road conditions, outside temperature, or towing/empty.

The truck consistently flashes a warning for “Service Antilock Brake System” and a scanning tool provides the code C0020-01. The truck was evaluated at a local mechanic, who indicated the code represented a general ABS system failure. I have researched the issue and found that this problem is a common complaint with 2018 Ram 2500s.
