ABS error code on truck approximately April 2023. Had tested at Dodge dealership in Marshall where they determined it was the ABS controller that was bad and had to be replaced. They informed me that this would not be available until August of 2023. This would mean that my anti lock braking system would not function properly for several months. I contacted two other Dodge dealerships in East Texas as well as an independent diesel mechanic who confirmed the same thing - this part would not be available until August 2023. I had Marshall dealership to put my name on list with others who had the same issue, and I had to continue driving the vehicle with the ABS system compromised, with the awareness and care knowing that this is a safety concern. August 2023, had not heard back from the dealership so I called and asked about the ABS controller issue. They told me they had been notified by Dodge that this part is not available in August and they had no expected date for it to be manufactured and available for these repairs. I Confirmed with other dealerships and two independent diesel mechanics. It is now mid September and I am having to continue driving with safety compromised due to the bad ABS controller and Dodge not doing anything to address this situation for me or what I understand are several others. No doubt, if they have not already happened, there will be accidents due to the extended time of ABS malfunction on RAM trucks. I am now reaching out to NHTSA as the urging of one of the independent diesel mechanics. I appreciate your time and attention and anything you can do to help Dodge address this widespread safety concern as soon as possible.

Abs and traction control lights are on. Cruise control will not work when lights are on. Lights go on and off with chime very annoying. Brakes will not function properly when lights are on. Contacted dealer no eta on parts. Almost 2 years now. Contacted dealer before warranty was out. Next time I went to ask I got another service rep and he said my warranty is out. This is not good.

I am getting a warning on this dash telling me that I need to "service electronic braking system". When this message comes up I lose my ABS brakes, cruise control and I get a traction control warning light. Sometimes this will stay on for weeks and then go off for a day and start all over again. When the road is wet you have to be careful with the brakes. I went to the local dealer in Bryan, TX and showed him the warning lights and he told me that I had a bad sensor in the truck. The cost could be as high as $1500. The dealership told me that they repair on an average (2) two trucks a DAY foy this PROBLEM. I had the truck checked for any codes in the system and the tech told me that I did not have any codes but yet the tech could see both warning lights on my dash. ABS light and Traction control light.

Intermittent Anti Lock braking system failure messages. From my understanding this is a very widespread engineering/ components failure. This is a huge safety issue and a recall needs to be issues. RAM was allowed to build trucks for years that had major steering issues, now the brakes don-??t work properly. The NHTSA needs to hold them accountable.

When operating the vehicle the Service ABS/Traction control light starts flashing and cruise control becomes disabled while driving. ABS and traction control becomes disabled. Safety issue! Advised the part will not be available until Feb 2024 and to operate vehicle as is.

What component or system failed or malfunctioned, and is it available for inspection upon request? On July 28, 2023, while travelling Northbound on Hwy 287 N, the engine brake automatically engaged without depressing the brake pedal or decelerating. Prior to this, there was no indication of any problem. No messages or warning lights appeared. I notified Karl Klement Dodge in Decatur Texas to inquire about braking problems or recalls affecting this model. I was told that I had no recalls, and they were unaware of any similar issues. On 9/11/23, after travelling approximately six miles, the ABS and traction control yellow warning indicator light illuminated and an audible warning ding initiated. These warning lights came on and off at recurring intervals, on multiple occasions. Eventually, the service ABS system warning initiated on the center control panel. At this point, I had driven no further than 8 miles. I proceeded to an independent service center in Bridgeport, Texas and spoke with a certified mechanic. He did a computerized diagnostic which indicated the HCU/ABS Module system was showing to be defective. The mechanic stated that they have had to replace this item on other vehicles recently. I again notified the Karl Klement Dodge dealership to inquire about my warranty or a recall or any other problems relating to the ABS or other braking system components. I was told that it would not be covered under warranty, and that there were no problems with the braking system on the particular model, nor recalls but that I could, "bring it in if [I] want to." The current mileage on this vehicle is only 24,314 miles as of 9/11/23. Due to the safety necessity of the braking system, it is a severe safety concern. Upon further research, I have found multiple parties with similar problems with the ABS system on this model.

ABS and Traction Control lights intermittently comes on and then will go off after a few minutes and "service electronic braking system" message appears. This may happen 25 times in a 5 mile trip and the next day not do it on a 30 mile trip. DTC C0020-01. Safety issue since ABS not working correctly and parts are very difficult to find. This is an on going problem, not a one time occurrence.

The "Service ABS" warning light randomly started coming on in the dashboard display. Sometimes it alerts every few seconds, other times it may not alert for days. When this happens I experience a loss of anti-lock brakes, traction control, and cruise control. This truck is used to pull heavy loads and the random loss of anti-lock brakes is not good. My local dealer says that parts are on on back order for many months. The potential loss of braking is scares me and is a danger to others around me. Yes, the vehicle is available for inspection.

Auto brake anti skid components failing creating unsafe brake operation while towing a 15,000 lb trailer. Dealer states parts won't be available for at least 18 months. This is a hard fault and can't be reset.Dealer states this is a high failure item on these trucks.

- Everett, WA, USA

The Hydraulic Control Unit Chrysler part number 68143491AA failed and been replaced multiply times on my vehicle. I have the current failed part available for inspection upon request. 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 twice both with the original part and its' replacements. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. There were no Warning lamps/messaged before failure only after. These would be ABS lamp and traction control lamp plus a service ABS warning message.

The service ABS braking system warning flashes on with a chime frequently when driving. This started 3 weeks ago. According to the Ram Forums this is a common problem with 2018 trucks. My truck is a 2018 with 352623 miles on it and according to the Dick Hannah dealership a part that is out of warranty. There is no replacement part since the original inventory was all pulled back from the dealerships to the manufacturer due to the incidences of failure. This information was given to me by the Dick Hannah parts manager. He said a newer more reliable version of the brake module is being built but replacements are not expected for at least 4 months. Ram knows the part is and was defective, i am out of warranty and have a dangerous truck to drive for the next 4 to 5 months then a estimated $1500 repair bill. I want Ram to pay for this and to expedite the replacement parts and the NHTSA to do their job and serve us the consumer instead of the manufacturer. I am seeking legal recourse too. I attached the repair code report derived from my Blue Driver code reader tool.

- Vancouver, WA, USA

ABS failed during a panic stop causing the vehicle to skid. Received a notice on the dash to -??Service Electronic Braking System-?? followed by the ABS and traction control lights coming on then off a number of times. It is my understanding that the Hydraulic Control Unit has failed, and FCA is aware of this issue. Failure of ABS in a large heavy pickup truck is dangerous, and FCA should issue a recall to repair the affected units.
