Hitting bumps causes an intermittent chime and notification alerting me that the Antilock Breaking System and Electronic Breaking System need service. Both the ABS and traction control lights are illuminated. I contacted my local dealer and they indicated that this isn't an immediate safety concern and is due to an electrical issue for which they haven't solved. They quoted me $1,600 for the replacement of the Anti-Lock Brake System Module and Hydraulic Control Unit. After some online research, it seems that this is a common issue with many resulting in total brake failures. A potential brake system failure should be a recall for obvious reasons.

The issue with the Electronic Braking System and ABS has worsened. The two warning lamps are almost constantly on, or rapidly come on and go off rapidly. If I'm towing a trailer, all braking is lost momentarily - brake pedal to the floor - including the trailer brakes. The trailer brakes do not return until an ignition cycle, if the warning lamps stay off, that is. The dealer says no parts are available, but won't even take it in for troubleshooting or attempted repair. This truck scares me. This has been an issue for about two years and 20,000 miles.

Service Electronic Braking System and Service Antilock Braking System lights have been popping on the dash for the last two months nonstop at random times. Sometimes I can drive for hours and not see them, then other times they flicker on and off constantly. It-??s very frustrating as my truck has only 27000 miles for a 2018. I-??ve checked rear wheel sensors and found a tiny bit of metal shavings which from what I-??ve read could be wheel bearings but still don-??t know a for sure answer. I-??m about tired of chasing down this rabbit trail. What caused this was I was backing my trailer and I started to spin a little and the lights came on so I clicked into 4x4 and lights stayed on. I turned the truck off and thought nothing of it and next morning truck had no lights on that day. But ever since then I-??ve been plagued with them going on and off.

C0020 error code. Required replacement of ABS system's HCU (hydraulic control unit). Vehicle's ABS and electronic braking systems warning systems would flash. Loss of cruise control when the warning light came on. Vehicle lacked ABS made especially dangerous in wet road conditions while towing.

This complaint is the same as many seen by googling this problem. There-??s a beep and then the ABS and traction control light come on. Message is given to service abs system. Then the message goes off and returns a few seconds later. this happens consistently during the driving duration. This only happens about every other driving session, but when it happens, it-??s consistent. This is a known incident that is happening in 200s perhaps thousands of drivers. It sounds like a malfunctioning part to me, plus I have no idea if I have a real issue. I called ram care with no help.

The "Service Electronic Braking System" warning comes on and off intermittently with an annoying "DING" while driving. It never stays on and always just comes on, DING, and goes away but repeatedly. It will eventually go away after driving a bit but then comes back unexpectedly. This also disables the Cruise Control. There are tons of complaints throughout the RAM forums and I see a lot of complaints filed here on NHTSA. The dealer is obviously very aware of the problem as the replacement parts are not available except for months of waiting, if at all. The dealership has not only stated the part is a long lead item and on back-order but it will be $1200 to $1600 for replacement and that part may fail as well!

The abs control module and HCU are faulty. No parts have been available for a fix. I have now been driving a truck in the north with no ABS, 4 wheel drive, cruise control or traction control. This truck is a hazard to everyone on the road but with no parts it-??s hard to fix it. I only have one vehicle. Tons of people have the same issue and nothing is being done. Ram won-??t do anything, stallantis wont do anything. It-??s just crazy

For the last 3 years the ABS and traction control warning lights come on and off intermittently. This occures every time the truck is driven. I have replaced the ABS control module and the Hydraulic pump unit with new OEM parts and this issue keeps coming back. Driving and towing heavy loads this truck is extremely dangerous (without a functioning ABS system). A recall is urgently needed!!!

Getting the Service Electronic Brake System, Traction Control, and Anti-lock Brake System. First noticed these alarms a couple years ago but they cleared by themselves. Sometime this 2024 Spring, around 70k miles these alarms started again. This time the alarms are nuisance going on and off multiple time a minute all by itself. Cruise control won-??t work when alarms are on. When I checked forums, seems like there is a problem with these modules. The supply of the parts is a problem also. I ordered the parts from Mopar and after I paid for the parts and received an order number. The next day Mopar cancelled my order tell me to go to the dealer. Seems like Mopar is monopolizing these parts.

On 8/10/2024 at 3.10 PM while traveling 68 mph on an interstate, the vehicle started displaying Service Electronic Brake System and Antilock Brake Failure warnings. This also shut off the cruise control system, causing a sudden and unexpected loss of forward momentum. The warnings would reset and then come on randomly while travelling.

Got an ABS fault for a corrupt hydraulic brake unit. So I replaced the unit at the cost of $200.. once replaced I still had an ABS light, traction control light, Brake light. Reading the codes it would tell me that both rear wheel speed sensors failed to compare. Ultimately I got a check engine light for wheel speed sensor 1 failure. So when I rest the code it clears the lights and I lose the speedometer for 25 plus miles. Also renders the 4x4 feature useless on the truck. I took it to the dealership on 8/8/2024 and they attempted to do an update to the ABS module. After the update I lost the speedometer again. I was told that the ABS module will need replaced at the cost of $600 plus labor and program time.

The electronic braking system/abs light/traction control light constantly comes on and off every few seconds when driving. Having intermittent loss of anti lock braking system is a hazard.
