Chronological view of owner reports
There is an open recall (C4B) for my Ram truck. The ABS light and "Service Brake System" light and message are currently displayed on the truck's dash. I contacted FCA about a year ago and told them I have an active issue. They said they placed me on a priority wait list but the remedy is not available yet. It is unacceptable for them to not have a remedy ready for an 8 year old truck when the issue was known about some time ago. I would appreciate if NHTSA or other government agencies would put pressure on FCA to repair this issue as owner's and other motorists lives are on the line if faulty equipment is forced to drive on public roadways. Thank you
Almost got into a wreck because my ABS failed. I was going down the interstate with my cruise control on and my abs and traction light came on. My cruise control.immediately stopped working and I was almost rear ended. I called the Ram dealership and they said they have no time frame of when they will have parts in to fix it under the recall. Does someone have to die before Ram will start fixing these abs units. The recall has been out since Nov 2024. They need to be held accountable or buy back all 2017 and 2018 rams affected by this.
Since January 2023, my truck stability control system has been disabled related to CB4 NHTSA 24V-896 recall. TWO years! I can't sell the truck like this & I have no idea when it will result in an accident. Stellantis needs to be held accountable. Every contact with them results in a response of waiting for parts. I've had no choice but to drive another 18000 dangrous miles with this vehicle. This is unacceptable.
Audible alarm, warning lights on dash. Come on and off. No cruise control available.
On September 8, 2024, I started getting intermittent ABS and Traction Control light with “Service Electronic Braking System”. Code C0020. When the light is on I lose cruise control. There is no specific condition that will cause the light to come on; i.e. bumps in the road, a certain speed, or setting at idle. The first instance of the light coming on, I was turning around in a parking lot, less than 5 mph. This cannot be associated to normal wear and tear. THIS IS A SAFETY ISSUE AND MUST BE A RECALL!!!
We bought this truck from a dealer in March of 2023. We were never informed by the dealer that the truck had this issue. ABS light and traction control lights come on & stay on for periods of time. Sometimes lights come on & off repeatedly while driving along with chime on & off. When lights come on, there is no cruise control available to use. I took it to the dealer we purchased from over a year ago and was told there was no solution for the problem. They said it was under an engineering review. No parts were available for a fix. I have documentation from the previous owner that this was occurring when he owned it in April of 2022. Since we pull trailers with equipment and also a large fifth wheel camper, we feel very unsafe when the ABS braking system and the traction control goes out while driving this vehicle. It is available for inspection upon request. When will there be a repair for this?
my traction control, cruise control unavailable, and warning light to service abs electrical system. Dealership said the hydraulic control unit has to be replaced.
Vehicle produces code C0020-1 ABS pump motor control failure, vehicle disengaged cruise control unexpectedly causing rapid deceleration. Dealer states ongoing problem with 2018 Ram 3500 HD trucks
Intermittent loss of anti-lock braking system and cruise control. code C0020-01 ABS pump failure. First occurred at approx. 47,900 miles.
Antilock brake warning light that says service antilock brake system comes on often if you hit any bump or rough spot. It continually dings and then the cruise won’t work. We have been told the part to fix it is unavailable. It is a horrible thing that cannot be repaired.
My 2018 Ram 3500 DRW truck for no reason started throwing dash warning lights intermittently after 60,000 miles. The warning lights activated on the dash were for ABS and Traction Control, with an annoying ding when they appeared. The center dash light stated "Service Antilock Braking System. Additionally, when this occurred the cruise control did not work. The warning lights were intermittent and just occurred at any time and disappeared as quickly as they showed up. This would happen for miles and for no apparent reason just stopped for a period of time. I took the truck to the dealer who informed me that its a known issue with the ABS HCU and the truck would be safe to drive but I would not have ABS and cruise control would not work. They also said parts were not available and could be a six month wait. They also told me that there were no recalls on the problem. I received a quote for repair which was in excess of $1,500.
Electronic Braking System failure. ABS lights come on the dash, chimes constantly and disengages the cruise control. The vehicle looses ability to use ABS. Ability to control vehicle safely when ABS disengages is a critical failure. I'm told by the dealer that NO parts available from the manufacture to cure this issue. This is an unacceptable answer to a known issue for years. Many RAM owners have complained about this on RAM related forums and on YouTube. I am adding my vehicle to list of vehicles impacted by this catastrophic failure to create a safe vehicle to drive. Why has the NHTSA not fined RAM and forced a recall? How many people have to die from ABS braking failure to qualify for a recall? I don't want to be the last death before something is done to make my truck safe to drive.
While driving, the "service electronic brakes " and traction control light will come on periodically, then go away. The issue is random and not consistent or easy to predict. If the cruise control is active, the cruise control will disengage and the truck will start to slow down. The brakes seem to work the same even if the light is on or off.
ABS mogel is defective and needs to be replaced. ABS light and chimes come on constantly. Affecting braking and lose of cruise control ability. This is a know fact that it is a defective part on ram trucks.
VEHICLE: 2018 RAM 3500 Dually ISSUE: ABS Module failure RESULTS: Loss of traction control, cruise control, and brakes locking up while pulling heavy loads. A constant chiming from check engine light. INSPECTED: By several independent garages can not find replacement module. Willing to let be inspected if need be. CONCERNS: Brakes lock up and loose control,Cause a accident by rear-ending someone, can't use all the functionality of the truck such as cruise control. Iritating chiming sound make long trips unbearable.
In May of 2023 while towing my boat I got warning bells and flashing lights, alerting me of the failure of the ABS brake system. In a few miles the warning went away. Then came back on, about 12 times in 20 miles. I also lost my cruise control and traction control. I took to the dealer, about 10 times before they were able to have the episode happen. It was intermittent at first but VERY annoying and Unsafe. The ABS system is almost always in failure mode and has been since about August. They order the parts in June, I'm still waiting. I use the truck to tow a car , a 34 foot 5th wheel and numerous other heavy loads. ABS is very important as is the cruise on my long trips. I'm still waiting, no help at all from Chrysler corporation!! Almost everyone I've talked to with a 3500 and larger truck, has had it fail. I'm tired of paying for a vehicle that is unsafe to drive. I want Chrysler to offer to buy it back, offer a good trade or repair. Please make them fix what they sell!!
Vehicle began flashing abs light and traction control light. Took vehicle in for repair. Was told this is a known issue and they are unable to aquire parts until june 2024 currently January 2024. Drove on 1-25-24 light was off used the breaks and abs light came on and breaks locked up and continued to skid on the ice almost causing me to go threw a stop sign into a ditch.
The antilock brake system warning light because it's faulty The brake system affects the speed control And they don't have reliable parts to repair
In September 2023 I started getting a warning to service the ABS system. The warning and associated annoying tone would appear and than disappear at different times. I spoke with the service manager from Lithia Dodge where I purchased the truck. He told me that he was unable to service my truck because the ABS parts are not available. I was told that like a great number of Ram truck owners, I had to "hurry up and wait for a solution." This is unacceptable. To make matters worse, I am moving out of the country in February. I had a buyer for my truck and now it is un-sellable due to this ABS issue. I hope that a re-call will be issued soon so those of us with this common issue can get some relief. Thank you
Truck has only 65, 000 miles on it, I’m the second buyer, has never haul anything or hitch a trailer, I’m having this electrical brake system failure ABS, this vehicle is to expensive and new to have early issues on it. ABS Motor Control- General Electric failure. I seem other similar problems reported with same year and same problems.
I purchased my Ram 3500 new, in 2018, at Nucar auto dealership in Tilton, New Hampshire. When I reached approximately 24,000 miles, my "Check ABS" and "Check Traction Control" lights activated on my dashboard and the message console. I was using cruise control at the time, which immediately deactivated. This could have caused an accident if I had been slower to react. The warning/failure was intermittent at first, but over the next few days became almost constant. The lights/warning would flash, the warning bell would ring, and then shut off for a minute. Over, and over, and over. I brought the truck to the dealer and they ran a diagnostic. They diagnosed the following: C0020-01 - ABS Pump Motor Control-General Electrical failure INTERNAL HCU OR ABS MODULE FAULT. WILL NEED TO REPLACE HCU AND RETEST The truck only had 24k miles on it, but since it was past the 3-year warranty period, they quoted a cost of almost $1,000 to do the repair, not counting the $155 they charged to run the diag. They also stated that the parts were on backorder, and wouldn't be available for some time. Since then, I have driven the truck as little as possible since it is a safety issue. Based on information in online forums, I know that this is a problem in thousands of 2017-2018 Ram 2500&3500 trucks. My next step is to join one of the several existing class-action lawsuits, create a new class-action suit for New Hampshire, or file an individual suit. Will Ram issue a recall for this?
Anti-Lock Braking system and Electronic Braking system, service system warning come on and off randomly all the time. Seems to happen when bumpy roads are encountered.
At around 50,000 miles my truck began to turn off cruise control while driving, ding, and the ABS ,as well as, the traction control light came on. It goes on and off repeatedly while driving. This is incredibly distracting and quite possibly dangerous for braking and handling. The local dealership is aware and have stated that even though it is still under warranty, there is no available part to fix it.
The ABS/ Traction control is intermittently failing. It is aviliable for inspection. When the light comes on I have no ABS or Traction control which may cause me to lose control under certain circumstances. The dealer has and the manufacturer has confirmed the problem. The dealership was able to reproduce the issue. The component was inspected by the dealership. There are the ABS/ Traction control light that comes on the dash sometimes. I have been told that the part that needs to be replace is backordered indefinitely and the manufacturer has no idea when they will get any new ones. From what reasearch I have done it looks like they need to reengineer the parts to make them work right. Also told that this is not covered by any recalls which I think is wrong as it is a safety issue that they knew about.
Electronic Braking System and Antilock Braking System is defective, similar to being described in FCA Case Number S2005000004. This issue also effects the Speed Control System
