2018 RAM 2500 Electrical System Problems

The ABS and anti skid lights on the dash come on and off sporadically. The pump and module have been replaced. The problem did not occur for awhile. Now it has started over again. It seems harder to brake since the problem has started.

The ABS Service Antilock Brake System messages comes on intermittently and chimes every 2-3 seconds. Some days the message and chime does not come on, but it is usually the day after the truck has been turned off for a period of time. The issue started on 16 March 2024, I still have the issue today, and it happens at any speed. After doing some research, I found that many of the same year and model truck has had the issue, and it seems to be the Antilock brake module Electronic Control Unit and or Hydraulic Control Unit. I contacted the dealership to see if I can get the issue repaired under my extended warranty, but the part is on back order. The vehicle is available for inspection, but I haven't had a chance to take it to the dealership as of yet.

The abs light and traction control light comes on intermittently which is caused by the HCU. Could cause a wreck

The ABS/EBS errors lights comes on and cruise control won't work. Did some research online seems like a common problem. Hoping to see a recall by Ram.

The anti-lock braking system, traction control and speed control system continue to flash on and off. While driving here in Huntsville, Alabama it snowed and my braking system failed causing me to nearly crash.

Abs light and traction control lights went off causing the truck to throw C0020-01 error. Dealer suggested replacing HCU and ABS MODULE

My 2018 RAM 2500 has 30,176 miles on it. Two years ago the HCU and module controlling the ABS system failed and was replaced. When the system fails numerous lights and warning chimes activate and the cruise control stops working. The system has failed again and the dealer tells me it will take 45+ days to get the parts necessary to repair the ABS system. After researching online I discovered an open class action lawsuit against FCA for this problem. I also discovered that this is a common problem with 2500 and 3500 RAM trucks after reading owner forum sites but so far no recall has been issued by NTHSA. This is a major safety issue for owners and needs to be fixed.

The ABS service light keeps coming on and beeping. It will go off after a little while but then returns intermittantly while driving. Apparently this is a known problem and should be a recall. Many owners are wasting thousands of dollars for repairs that should be covered by a recall.

The component or system that is failing or malfunction is the ABS Hydraulic Control Unit (HCU) and ABS module. The malfunction is turning off my ABS and TCS system, making the vehicle unsafe to drive. Also the ABS and TCS dash lights are constantly dinging and going off and on distracting me while I'm driving. This issue is well know with the dealer. Here is a TBS from 2020: RAM TSB S2005000004 The vehicle has been inspected and and the ABS module was already replaced, but didn't fix the issue. This has been happening since I bought the truck.

My truck has right at 80,000 miles. Every so often I get two dash lights. One is ABS service and anti skid warning. They randomly show up. They pop up very quickly then go away. But it happens non stop. I have done some research and it seems that there is thousands of people with the same truck and year model with this same issue. I went to the dealer in Seguin, Tx and they told me that there was really nothing I could do to fix the issue, unless I wanted to wait eight months. But the new part rarely last. They flat out told me to not follow any one too close because hard braking could fail without anti skid working properly. RAM needs to make this right. I can’t believe that there has been this many people complain about a serious safety concern and nothing has been...

Warning light to service the Electronic Braking System came on. Has been intermittent since. Contacted dealer and the HCU needs replacing. Vehicle is under mfg extended warranty. They claim part not covered. There are hundreds of complaints about this along with a class action lawsuit filed last year in CA. Brakes may fail without repair. 4WD will not engage since warning light came on. Lawsuit alleges Chrysler knew of this defect before selling. I have scheduled a replacement of the unit for 3/1/2024

The truck last year started flashing the ABS and traction control lights. On the screen it says I have to service my braking system. As soon as that warning comes on, I lose traction control and it’s awful to dry in snowy or wet conditions. The truck just hit 28 thousand miles. I contacted the Ram dealership and they are aware of the issue but stated there is no recall so they’re not addressing the issue.

The abs/traction control message goes off intermittently. The truck dings and beeps from the dash with a message that says “service abs”. This is a known issue with this yr/make truck.

Service electronic brake system code came up. Brought it to the shop and they said it’s a known issue with this year model and ram is aware. Told me it’s a $2500 fix. I feel that a safety issue that is know and I had to fix myself is not fair in its self not safe!

Abs General Electric failure. I don’t have traction control or abs and I live in the mountains where these systems are necessary. Very unsafe and parts aren’t expected till June 2024

The truck constantly has an ABS Module and Stability control failure/ code turning on and off causing the ABS/ Cruise Control/ Traction control to no longer function. Research shows that the ABS Module and Hydraulic control unit need to be replaced and programmed by a dealership and parts are nearly impossible to find

ABS and EBS warnings, traction control warnings repeatedly turning in and off. Code - C0020-01. Cruise control inop when lights/chimes are going. This has been going on for nearly 8 months.

Service Antilock Brake System Service Electronic Braking System Illuminated warning lamps. Impacts Braking and cruise control. Started 10/2022, and appears to trigger randomly and frequently.

I have been having antilock braking system and electronic braking alerts come on the dash of my 2018 Ram 2500 for a couple months now. I have tried to have it repaired at the Pohanka Ram in Salisbury, MD in which I was told that the ABS module and HCU unit were under "engineering review" and all parts would not be released to repair. I also confirmed with the Lakewood Dodge Dealership in Seaford, DE and IG Burton Ram in Georgetown, DE. All 3 dealership report the same issue that RAM will not release the parts for repair. I have a truck that is an obvious risk on the road, and will not pass Delaware motor vehicle inspection in March when my tags end. I have seen that there is a class action lawsuit and a huge amount on owners reporting to this agency. This is huge issue and is...

The truck flashes service antilock brake system, service eletronic brake system. It cancels the cruise control on truck. On several occassions it shuts off cruise while on the interstate. You have to react very quickly to avoid having an accident. A couple of times its happened while pulling a travel trailer and nearly got rear ended by semi truck. Thats really scarey. It started about 8 months ago. Have contacted dealer and was told by service department that they know of about 2000 trucks has same issue. The parts are out of stock and back ordered. I think this is a real safty issue. Dont know what to do about this.

Hcu, hydraulic control unit, no abs, no traction control, no cruise, no 4x4 and emergency brake light on won’t go off and part is not available been waiting for over a year and a half

Got in my truck one day and my ABS and Traction Control Lights both came on, as well as a notification in my central dash advising to service electronic brake system. At first the lights where intermittent and random. I could start the truck and the lights would be off. Apply the brakes to put in gear and the lights would come on. Drive down the driveway and a bump would turn them back on and pressing the brakes would turn them off. Now the lights stay on permanently. The ABS error code I got was C002001, or ABS pump general electric failure. I called several local mechanic shops and they reported to me that this is a known issue, parts are on backorder. I called the dealership, was advised the same with the addition that Dodge/Fiat, not only new about the issue, but changed upgraded the part and gave...

ABS and traction control lights came on. The dealer said that it was the control module. It has been replaced. There were no braking problems but concerned that it would eventually be a problem.

This vehicle has faulty or defective ABS braking system. The warning lights and warning chimes have been constantly going off for approx. 2 years. The Dodge/Ram dealerships admits that this is an industry wide defect with 2017 and 2018 Ram 2500 trucks, but say they have no parts to correct the problem. Their suggestion to me was to buy a new truck which is not acceptable or affordable. This was identified by both the dealership and Chrysler as being a safety issue with no resolution from Chrysler or dealer. I use vehicle to transport my grandchildren and livestock and truly doubt my ability to operate safely without the Federally required working ABS system. This is truly a safety issue and an immediate recall is necessary. Ram/Chrysler will not correct issue without recall. I am limited on the use of my vehicle but have no choice as it is my only...

I have replaced the ABS/HCU 2 times as of 1/1/2024. I am currently waiting for the 3rd one. The ABS system is unreliable and dangerous during the time of waiting for parts availability. The dealer diagnosed the vehicle in 10/2023 and has been unable to get parts to repair the problem.

Abs and traction control light going off and on causing abs and traction control to be disabled. Safety issue being able to control vehicle if had to get on brakes hard Problem was able to be reproduced by the dealer and this has been replaced once before on the truck while under warranty, Component has been inspected by dealer and found faulty on November 16 2023 but informed it would be late January 2024 before they would have parts, now it is late January and they say parts are in the development phase and would be late June or July before they might have the parts. Concern is have a 2018 truck with just over 32000 miles on it that has had the same issue twice and they can not fix, Advised by dealer and ram customer service that they advise not to drive truck, but they will not loan...

I get a warning that flashes on the dash multiple times every time I drive stating that I need to service the electronic braking system. This warning is also accompanied by the traction control and ABS warning lights. The warning and lights do not stay illuminated and flash on and off several times during the course of even a short drive and the warning bell sounds every time as well. At minimum this is a huge distraction when driving and even worse I do not know if I can trust the brakes in the event of an emergency stop. I looked at fixing the issue by replacing the ABS and HCU units, but those parts are back ordered well in to 2024 now. Reading on various forums, this problem seems to be pretty common, but as far as I know no recall has been issued by Chrysler.

Since incident, the messages continue to appear in my dash. "Service Antilock Brake System" and "Service Electronic Braking System", flashing on and off erratically. I talk directly to Mopar which is overseas, and they tell me it isn't covered because its under the basic warranty which has expired. I asked them to send me the documentation so I can see it in writing and they said they cannot send it or show it to me and that only they can see this information. I am concerned that they are not being honest with the warranty coverage because my five year/100,000 expires in June 2024; and ironically they said the ABS part isn't available until June.

Electrical warning for electronic ABS Braking System and Module to include traction control. Initial evaluation at Dealership on 10/25/2023 Since then, the parts have been order, but unavailable through the dealer or through the Customer Care team at Dodge. Multiple phone calls, emails, etc., and still the parts have no estimated delivery. No solution has been offered by the Dealer or by Dodge and the truck is unsafe to drive.

Code C0020-01 appeared. ABS pump motor control- General electrical failure. Problem occurred in heavy snow storm. Traction control would not work, anti-lock brake system would not function. Brakes locked up causing vehicle to skid.

Electronic Braking System Needs Service Error that can't be addressed at the dealership.

I had an intermittent abs/traction control light that now stays on 90% of the time. Code C0020-01 for ABS general electrical failure.

The truck developed a warning light for ABS / Stabilitrak needing to be serviced. Ram dealership replaced an ABS Pump, but the issue came right back. They are now saying it needs a new control module at great expense, but that they are unavailable currently. Delivery on the part has been pushed back continuously over the last 12 months, still no parts. This issue causes a regular intermittent digging and warning light in the cab, disables ABS, disables Stability Control, Disables Traction Control, and Disables Speed Control (Cruise Control). This issue has been ongoing for 8+ months at this time with no developments from Ram and the vehicle in an unsafe and compromised condition.

Service anti lock braking system and electronic brake system code constantly coming on. This is an apparent safety issue that Dodge needs to resolve. After much research, I’ve discovered that there are many, many complaints of 2018 Ram truck owners having the same problems. Thanks for all your assistance.

Electronic Braking system failure affecting the ABS system, Traction control, and cruise control. It puts the safety of everyone in the vehicle and on the road at risk because the ABS and cruise control will fail causing an unexpected adverse conditional that can lead to an accident. This is a known problem for RAM and their is no fix at this time other than making the customer pay out of pocket for the broken parts to be replaced with the same parts that will fail shortly after. There needs to be a recall and a permanent fix from RAM

ABS and traction control lights keep turning on and off. Truck currently has no ABS.

Brakes when depressed do not pull equal. No cruise control. 4 wheel drive is not working properly. Traction control not functioning properly Have brought vehicle to a garage. Abs/hcu unit is the problem.

ABS and Traction control has been lost and have created a safety risk especially during inclement weather. The ABS pump or the ABS control Module is faulty in multiple years Ram vehicles. I believe based on forums there is a recall issue with these parts.

Radio keeps going out and turning off, and then comes back on with different stations. Next is my outside mirrors on both side , heater to mirrors don't come on at all to defrost

I’m receiving two codes; Service Antilock Brake System and Service Electronic Braking System. I met with my mechanic this morning and he said that this is a very common problem with the 2018 Ram 2500. Since this is a reoccurring safety issue i feel that Dodge should resolve not the owner. Should I get in an accident from a break failure who is responsible?

ABS and Traction control lights keep going on and off, this still continues and it looks like Ram knows this is a safety issue. Dealers have no parts for repairs

The HCU in which controls your ABS and Traction control will malfunction while driving down the road when this happens you have no ABS, traction control or cruise controls. The dealer part is unavailable through the dealer due them saying that they are reviewing it. This is a major safety concern due to the fact if you are traveling and it malfunctions and need to stop quickly you cannot or if it malfunctions and have cruise control set to a speed it will slow you down and can cause an accident. When vehicle was carried to dealer and asked what to do the dealer just said to drive it and don’t follow to close to anyone, that is not the answer that needs to be given.

The display in the center console keeps asking if i want to update the clock. Nothing stops it from constantly popping up…going off… popping up. Truck only has 25000 miles

Traction control/ABS illuminated on dash board as error codes. When driving at any speed the brakes are grabbing the rotors without touching the pedal. The feel is like tapping on brakes. I've replaced wheel bearing hubs for ABS speed sensors, replaced all speed sensors. Replaced the ABS MODULE and HCU MODULE and to no avail. Chrystler has had the main components on backorder. The error codes are targeting both components ABS and HCU. The Ram community has the same concerns as I do. This issue should be recalled because the ABS and HCU prevent from fish tailing and erratic traction

ABS Brake system failure. Multiple reports of ‘17-‘18 yr models with exact problems.

ABS/TRACTION CONTROL intermittent alarms. Vehicle alarms on and off constantly. Dealership has said they have no fix except replace all ABS electronics for about $4000.00 and can not guaranty it will work. This constant alarm turns off the Cruise control.

Truck throws code C0020-01 and my ABS and traction control lights on dash board start to go in an out. Proposes a HUGE safety risk. Truck has 48,000 miles which puts it out of the warranty that covers this issue. Lots and lots of info online about this being a common issue and RAM has yet to recall it still.

Intermittent ABS / traction control light and dinging! 49000 miles. Just like every other person complaining about the same exact issue on 2018s. I’m a disabled vet with a family of four on a single income. I can’t afford a 1200 abs module that lasts only 1-2 years. Clearly this is a major manufacturer issue, experienced by many Americans. This needs to become a recall. This is [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

abs traction control light abs brakes dont work

The abs and traction control keep going in and out and is very unsafe to drive such a large truck. I called dealership and they don’t have the abs module and haven’t had it for over a year. So they know it’s an issue and can’t give us any since manufacturer is at fault. My abs and traction don’t work. Thank you
