There are 50 owner-reported speed control & cruise complaints for the 2018 Ram 3500in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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
Slide off road while braking. Braking problem due to recall, Manufacturer Recall NumberC4B / NHTSA Recall Number24V-896. Recall was to be fix 1st quarter of 2025, Now 2026 still not repair solution.
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.
Traction control and ABS work intermittently. Ram sent out this notification for recall concerning stated problems but state there is no fix at this time. They continue to state there is no fix. This is a safety issue and you are not forcing them to repair. They are dragging their feet hoping it goes away. DO SOMETHING!!!!
Hello, I have an issue with the ABS Braking system on my 2018 RAM 3500 with only 50K miles on it. The lights are constantly coming on and off telling me that my ABS system needs servicing. this has been going on for two weeks. I was able to troubleshoot the problem and it says that my ABS pump and Module needs replacing. I was going to replace myself and when I ordered the parts from MOPAR they told me it was a 2 month lead time which I thought was unacceptable being such critical components to a vehicle. This week I almost rear ended another vehicle because the brakes failed. I have been online reading about the stories of these same complaints from many RAM & JEEP owners. How this company is getting away with safety issue is beyond me as this is going back to 2023, how are there no safety recalls on this not issued yet and customers not being reimbursed for the repairs. The issue was diagnosed by my independent mechanic using his scanner. If you require further info on this please feel free to reach out to me.
THE ABS BRAKES YES IT IS AVAILABLE FOR INSPECTION BY NOT HAVING ABS BRAKEING WHEELS HAVE LOCKED UP HAVE NOT HAD DEALER CHECKIT HAD A MECHANIC PUT ON COMPUTER FOR CODES NO TRUCK HASN'T BEEN INSPECTED BY ANYONE ELSE BUT THE MECHANIC WARNING LIGHTS HAVE COME ON AND OFF A NUMBER OF TIME AND LATELY MORE OFTEN IT STARED ABOUT A YEAR AGO TOOK IT TO DEALER THEN BUT WASN'T REPAIRED PROPERTY
Audible alarm, warning lights on dash. Come on and off. No cruise control available.
I started getting an intermittent error code on my truck with only 36k miles on it. the traction control, abs and cruise control wont work when the service electronic braking system code is present. I have done a lot of reading and this seems to be a very common issue with the 2017 and 2018 ram trucks. It is so common that I called my local dealer and the part is on back order for months. I am getting very close to taking a long road trip with a 20ft trailer, which is the reason I purchased this truck. Now I cant even get a replacement part, that is a known issue and I was quoted $1100 for it. Braking system seems to be a safety issue, why isn't ram doing something about this issue!
Intermittent loss of anti-lock braking system and cruise control. code C0020-01 ABS pump failure. First occurred at approx. 47,900 miles.
my traction control, cruise control unavailable, and warning light to service abs electrical system. Dealership said the hydraulic control unit has to be replaced.
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?
A diagnostic code has been displayed for the Anti-Lock Brake System - C0020-01 —> ABS Pump Motor Control - General Electrical Failure. Going over a bump in the road will cause the ABS system to deactivate the cruise control. The diagnostic code can be cleared and the cruise control will resume. Reading on RAM / Cummins online sites, many say that either the HCU and / or ABS Module needed to be replaced and many submitted reports to the NHTSA to start an investigation. No damage has been evidenced at any of the wheel sensors. With the ABS illuminated, it appears that the unit wouldn’t function if needed. The clearing of codes has been done numerous times. First noticed in about January 2024.
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
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.
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.
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 ABS light and Traction control light keeps coming on and off very frequently. I am being told it is the Hydraulic control unit, as well as the abs module. This seems to be a huge safety issue that many people are running into.
The Hydraulic Control Unit Chrysler part number 68143491AA failed and was replaced on my vehicle. I had the vehicle back to the dealer numerous times before they replaced this item. 14000 miles later the same problems are happening again. 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 vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. The warning lamps and messages will flicker on and off repeatedly and randomly while driving.
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.
