Hi, The ABS System shows Service Antilock Brake System at the display, It comes and go so I assume that it is an intermittent issue, it does stays for hours or days and go on ad off during the whole drive, definitely is an issue. It allow the brakes to preventing locket when brake on certain circumstances. Had an issue on a wet pavement and have to handle to avoid crash with other vehicle cause the tires got locket and the truck slipped on the pavement for a considerable amount of feet's. Dealer inspected and replaced the module under warranty when I bought the truck and told me that it has to be replaced again.
The Hydraulic Control Unit begins to malfunction presenting on the ECU as C0020-01 ABS Pump Motor Control-General Electrical Failure. This is fairly common in 4th generation 2500-3500 RAM trucks. The malfunction affects the ABS system, Traction Control system, and Adaptive Cruse Control system by deactivating them when the malfunction presents. This could cause the braking system and other systems to not perform in hard breaking/ emergency braking situations causing the operator to loose control of the vehicle. The Traction Control system and ABS system warning lights illuminate on the dash and the message of "service electronic braking system" is displayed on the HUD.
ABS and traction control lights come on intermittently. Cruise control won’t work when this happens. Problem seems to be a wiring issue and mainly happens during wet conditions and then stops after engine compartment warms up. I’m guessing ABS brake’s won’t function when light is on.
There is a problem with the ABS module and hydraulic control unit. This turns the ABS and traction control off. This is a known issue with several complaits.
Automatic electrical braking system failure while towing.
ABS KEEPS GOING OFF started at 50 thousand miles it says its the abs module .
The truck has 57,000 miles,just started getting intermittent ABS, and Traction Control lights coming on and the dinger goes off when the lights come on. Thanks
Abs light keeps intermittent and loss of traction control! Hcu or Abs module is the problem for the intermittent cycle on the dash! Seen other people having similar problems with that particular year 2017-2018 rams 2500-3500 models.
Abs light comes on all the time and cruise control goes out and go 50 miles and the abs and brake service lights comes on 67 times
The contact owns a 2018 Ram 2500. The contact stated while driving 55 MPH, an alarm sounded, and the ABS and traction control warning lights illuminated. The contact stated that the failure had been recurring while driving, causing the ABS and the cruise control features to become inoperable. The contact stated while driving and slamming on the brakes on several occasions to come to a complete stop, the ABS was inoperable, causing the tires to lock and the vehicle to slide. The contact who is an independent mechanic, diagnosed the vehicle and determined that the ABS module had failed and needed to be replaced. An unknown dealer was contacted for parts several times and informed the contact that the part was on backorder. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.
Abs light. Electronic brake failure light
For the second time since the vehicle's purchase in 2019, the Antilock Braking System is flashing an intermittent error stating that the Antilock Braking System needs to be serviced. When the system flashes the error, the antilock brakes, cruise control, and stability control become disabled. The error sometimes will clear itself, and then immediately return a minute or two later. Three years ago I had this same issue repaired once before under the vehicle warranty. At that time, I was told the Hydraulic Control Unit for the ABS system had failed. Now, without warning or reason the system is failing once again and RAM refuses to replace this defective part. Through an online investigation, I have discovered that thousands of Ram owners are experiencing the same defective part and circumstances. Without proper functioning brakes, antilocking brakes and stability control, the vehicle cannot be driven without great risk to the vehicle's operator and occupants, and additionally other motorists.
Electronic brake control module failure, 2 nd time . Vehicle has less than 46000 miles. I am told this is. Very common problem due to defect in control motor and causes a braking safety issue.
ABS, traction control, cruise control, 4WD works intermittently ABS and traction control warning flash, wile ABS light is on you can not use traction control ABS system does not engage and cruise control is inoperable. Seen by dealer (benson CDJR) in April and June of 2023 and parts to repair were NOT available. Being seen again as new part is currently available to be repaired 4/6/24. After 1 year of not being able to find a solution for the problem. I have slid on sharp turns, got stuck wile pulling camper due to no 4wd among other issues. Contacted RAM regarding replacement assistance and they denied due to after market warranty. I am still responsible for 250$ for a repair that should have been a recall for Sevier safety concerns by RAM
ABS and Traction light on dash. Chiming of alarm. This alarm turns off cruise control and feels like it applies the brakes at 70 mph. Lots of brake dust accumulating on my rims. It happens some days but not every day. Some days there is a constant alarm chime and cruise won't activate. On 10/24/23, parts weren't scheduled to be released until February 2024. Charged over $100 diagnostic fee for the ABS, traction control lights on the dash. By looking at other reports, this has been an issue for several years. They have known for over 2 years that there is an issue. Why is it taking so long to get a fix in place? ABS is a safety system. This should be a recall. The recall should cover replacing the brake pads and rotors also.
ABS and traction control lights going off and on. Stating abs need serviced. Took to a auto maintenance and told it need anew pump and module would not be available until August 24,2024. In January 2021hydraulic unit was replaced now need to replace it again
Abs and traction control light come on. Then off. Some days every 5 minutes. Some days once a day. Alarms sound. ABS and cruise control won’t work. Dealer reported over 10k truck have issue. Parts are on backorder for 6 months. I was told july 2024 for part. There should be a recall. So many trucks with same problem.
The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed and attempting to slow the vehicle, there was an abnormal grinding sound emanating from the brakes. The traction control and ABS warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the rear brakes. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 75,000.
Hydraulic Control Unit failed, along with the control module per dealer diagnostics. The ABS warning and traction control light is flashing consistently, and the ABS system is not working. The dealer has indicated there is no estimate on when these parts will be available. This is the third occurrence of the same bad components.
2018 Powerwagon intermittent abs traction control light dinging on and off randomly. Does it more in bad weather. During dry sunny days sometimes it never comes on. From what I can tell I don’t seem to have any problem with my brakes.
My truck had warning lights come on in December 2023 saying to service the anti-lock braking system and the electronic brakes. I took it to a mechanic and I was told that the part would take at least 45 days to get. Now we're being told it will take 3 months to get because it is impossible to find. After researching this online, it is a nationwide problem for many Dodge Ram owners. These vehicles are out on the road needing this part to keep their brake systems from failing and it is impossible to get.
I keep getting an Electronic Brake Service message and ABS message that randomly starts dinging and popping up on my display that also disables my cruise control. This obviously is a known issue and I would like to know what is being done to correct this. I have read several and seen over 3000 reports of this problem so why is it not being addressed to make our vehicles safer when it is a known fault. We travel with our camper and travel baseball all summer long and this is not acceptable when it comes to my family or the safety of others on the road around me.
ABS is not functional. HCU and ABS Pump are failing and there are constant service lights that come on. Is very dangerous and dealer claims part is back-ordered.....Extremely dangerous to not have proper ABS.....
The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed with cruise control activated, the vehicle experienced a loss of traction control and brake performance. The cruise control then inadvertently deactivated. The Service Electronic Brake System message was displayed, and several unknown warning lights were illuminated. Additionally, the speedometer and tachometer dropped to zero while driving. The contact pulled over and turned off the vehicle, but the vehicle failed to restart. The contact disconnected and reconnected the battery to reset the vehicle. The vehicle was able to restart. The vehicle was taken to the dealer, where the HCU was replaced; however, the failure recurred. The vehicle was taken back to the dealer, where it was determined that the ABS module needed to be replaced; however, the part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The contact related the failure to the federal safety agency Action Number: PE22012 (Service Brakes, Hydraulic). The failure mileage was approximately 46,000.
Warning lights and audible warning for ABS and emergency braking along with traction control have been active for several months. Dealer determined the ABS control module is faulty and needs replaced. Current lead-time for the part is 7 months and cost to replace is $1,200. While the warning is active the cruise control and traction control are de-activated. During a recent rain storm I had to accelerate to avoid a merging vehicle on the freeway and the rear tires broke loose due to the lack of traction control and sent me into an uncontrolled fish-tail across 3 lanes. Fortunately traffic was light and everyone was able to avoid me and I got it under control and stopped just before hitting the freeway barrier wall.
The vehicle has lost all antilock brakes Lights on dash warn there is a issue with vehicle safety capabilities. The trailer brakes will not activate. Dealer says common issues with 2017 2018 and cannot fix due to parts not available for a year. People are putting their lives in danger operating this truck with this issue. I have had work on this problem before costing thousands of dollars. I can't belive you let them effectively shun safety and lives.
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.
The ABS light continuously comes on and off, especially when hitting a bump or going down a gravel road. Traction control light and ABS light will come on and off which ultimately causes a lack of control when roads are icy or wet. It's especially dangerous while in tow.
I have an intermittent abs warning that turns off abs,traction control, and makes the truck brake worse when it happens. Diagnostics indicate a abs pump failure performed at dealer and an independent shop. Dealership says there’s a hold on the part from Chrysler engineering. I have been informed it’s several of the 2017-2018 2500 rams and makes driving the truck dangerous.
