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.
2018 Ram 2500 brakes complaints
Page 29 of 79: complaints 821 to 850 of 2,349, newest first, as owners wrote them.
ABS pump motor control and anti-lock brake hydraulic unit is out again. first time replaced at dealer on 12/27/2019 second time8/10/2022 and now ABS light flashing again for about 3 weeks now with code c0020-01. This should be a recall it is very dangerous to be hauling heavy equipment with this reoccurring problem approximately every 20,000 miles or so.
The abs/traction control lights are coming back on again. The abs control module and the hydraulic control unit were replaced when the truck had 34,000 miles. Now it has close to 60,000 and it has started doing the same thing again. Talked to the dealer and they said it would be close to $2000 to do the repair this time since it isn't under warranty. I have seen many of this same problem in a lot of the ram or cummins forums and feel this is a known issue and should be recalled. You lose the abs and traction control when these are out but it is intermittent. Fortunately, I haven't had an accident from this so far but could very well see how it could cause an accident. When my traction control was out the truck fish tailed on a wet road.
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.
Service ABS brake system warning lights.the ABS unit was replaced 6-7-2022 at feldman dodge when the lights came on at 15525 miles.now the lights are coming on again at 30000 miles this seems to be a known ram problem.please advise [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)
ABS control module/pump very common problem with this year truck that Fiat/Stellantis needs to address.
Abs not functioning. Multiple online forums with complaints for faulty abs module and pump. Abs pump not working. Scanner will not communicate with abs. 2017-2018 Ram 2500 very common known issue.
Code C0020-01 appears and ABS service light appears - the vehicle is equipped with a defective and dangerous hydraulic control unit (HCU) module and anti-lock braking system (ABS) module. Anti-lock braking, traction control and speed (cruise) control are inoperable. Causing a safety concern
The Hydraulic Control Unit Chrysler part number 68143491AA failed and been replaced previously on my vehicle. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. The problem has been reproduced by my local dealer and the vehicle will be dropped off for evaluation again this week. The manufacturer has not evaluated the product. Abs and traction control lamps are intermittent when the issue occurs.
I have had the ABS/HCU replaced a year or two ago and now I’ve got the same issue again today 8/30/2024. Code C0020. I have to wait to get it to the dealership after the long weekend and holiday on Monday so they can check it out. Lights flashing in the dash and cruise control is not working when this happens.
Abs traction control light
ABS light and traction control light randomly come on while driving and sometimes apply the brakes without warning. Scanned for codes and was given a codes for an abs module failure. This seems to be a very common failure on these vehicles and should be addressed with a recall as it is very unsafe. I have almost been rear ended several times.
My 2018 Ram 2500 had a ABS/Traction Control warning light and I took it back to the dealer 01/12/21 and had the the HDC replaced. Mileage on the truck at that time was 16,220. Warranty covered the problem. Problem returned and took it back to the dealer 04/28/23. Mileage at that time was 24,824. Was told that it was no longer under warranty. Was told the part only had a two year warranty. The dealer didn't have the part at that time due to numerous problems with this system. Truck only has 29,022 miles at this time. I haven't had the part replaced and just have to listen to the warning chime continually sounding. Researching the internet reveals this problem is very common and should be a recall with the manufacturer fixing this known problem. I have the Dealer Service Documents.
Vehicle gives warning on the dash for ABS and anti skid off. Along with an audible warning. the warning on the dash states the anti lock brake system needs repaired. While this is active the cruise control does not work as well as the anti lock and anti skid system.
error code c0020-01abs/hcu pump motor control. i am one of thousands with the problem of getting abs and traction control lights flashing on my dash of my truck. it takes away my abs brakes my cruise control and the trailer brakes. i use my truck to pull a large trailer which has forced me to stop using my truck and it is now useless to me.please help us all and force ram to recall and fix our problem. my truck is a 2018 2500 and has 18,000 miles on it. and now i can not use it.
ABS /Traction Control warning chimes and lamps providing erratic behavior and constant noise/distraction. In doing some basic research, this is a known issue for these trucks.
My ABS and HCU modules are both bad. Leaving me vulnerable to locking my brakes on wet roads. My traction control will not work because of this as well. This is unsafe.
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.
ABS hydraulic control unit motor failure, occurred at 25k miles, just outside of 3 year warranty as I bought truck used from a dealer. Intermittent loss of ABS and traction control with no warning, and constant dinging sound while driving as the motor reconnects and disconnects. Currently have 40k miles, have not repaired as from what I’ve heard from other owners and seen online, the repair is $1000-$2000 depending on dealer, and the repair may only last 25k miles if the part installed is of the same build quality. Many owners have resorted to replacing the ABS pump motor with parts from other makes/models of vehicles, as it seems the Mopar part is dealer-only availability at this point. I have found a dealer source that has a new upgraded part number that I will be ordering from and finally replacing, but I have no hopes that the part will last any longer than others have seen. I am only replacing the part as there is a class action lawsuit pending. My hope is that a safety recall be issued, as this is a prevalent problem in the 2017-2018 Ram trucks.
Vehicle constantly displays “service electronic braking system” message. ABS light will not turn off. Dealer tells me there is nothing they can do for me and they have multiple customers with 2018 RAMs with same issue and replacement parts are not available.
While driving pulling a trailer the service antilock brake system light started to flash on and off sporadically the entire time i was driving. It does it now every time i start the truck. Doing research it's a know problem. The truck has 43k miles. While the light is on the braking is not what it should be for a truck that can haul the loads it's supposed to. Definitely a safety hazard.
The Service Anti-lock Braking System warning lights and audio alarms come on almost constantly at times along with the cruise control failing, a common problem I understand which Dodge Ram has to be aware of. This truck has only 7000 miles on it!
The service electronic brake light and traction control light on my 2018 Ram 2500 keeps going on and off while driving. This started with only 12,048 miles and 6 weeks over my 3 year warranty. Research shows that this is a common issue with 2018 Rams and newer. Thousands of complaints have been reported and there are several Class Action Lawsuits regarding this issue in several States. Also being reported, is that this issue causes towing problems and the cruise control to malfunction, so I don't dare to use either when traveling. Even with repairs, if you can find the parts, some owners are reporting several repeated failures. You can't replace defective parts with more defective parts and expect a resolution to the problem. Though I have not had brake failure yet, and with only 27,000 mile, it is always on my mind while driving. I don't feel safe when driving my vehicle, hence the low mileage. Chrysler needs to be held accountable and a recall needs to be issued for all makes/models/years having this issue.
ABS and TCS modules failing cruise control and abs unavailable when lights appear on dash. Vehicle not inspected by authorities or dealer at the moment will take to service center shortly.
ABS Pump Motor Control: General Electrical Failure code-C0020-01
Abs module failure. Traction control failure Stability control failure. Module replaced by dealer once under warranty and failed a little over a year later. Dealer would not replace defective unit stating it was out of warranty.
The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, several unknown warning lights illuminated. The vehicle was taken to the dealer where it was diagnosed with a failed HECU module. The contact was informed that the HECU module needed to be replaced. The vehicle was not repaired. The contact was informed that the repair was not covered under warranty. The manufacturer was not made aware of the failure. The failure mileage was approximately 53,000.
My abs system is not working the ETC is not working was told this is because of the abs pump and abs computer. Most safety components related to brakes not working. There are over a thousand complaints to Chrysler about these trucks and still no recall. Please help.
abs warning light comes on. Dealer stated it cannot be repaired.
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 the federal safety agency. 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!
