2018 RAM 3500 Complaints

At 26075 miles 9/10/2020, got error saying service electronic braking system. Dealer diagnosis code C0020-1was HCU (hydraulic control unit) failed; replaced unit part number 68143491AA. Problem solved. At 34412 miles 5/31/22, got same error stating to service electronic braking system. Dealer diagnosed code C0020-1, HCU failed. They replaced part number 68143491AA, again problem solved. At 40,125 miles, 8/30/2023 same error message. I will be taking to dealer, but parts are not available until February 2024 or later. When this unit fails, ABS is disabled, as well as trailer braking and cruise control. This creates a serious danger as the truck is capable of towing a load in excess of 17000 lbs. using the same part that appears to have an issue is not the solution.

HCU failure at 75k miles causing loss of ABS, Traction Control, and cruise control functions brakes are not as efficient anymore part is 8-12month back order, fiat Chrysler dealership locally said nothing we can do don't drive it wait for $700 part to come In some time in the future. Only vechicle I have I. Self employed can not just park truck for 8-12 months and continue to make payments, there is no option to sell as someone will not buy with abs issues and traction control in-op. This is a wide know issue on rams fiat Chrysler has done nothing to ensure the safety of its drivers and owners. For them to simply say park it do not drive wait 8-12 months to be fixed is absolutely ridclious. A reca needs to be issued and part failures need to be handled. Quick search on line shows many trucks having same problem and same results at dealership.

ABS/HCU intermittent failure resulting in loss of traction control, ABS function, cruise control. The risk associated to myself and others is the loss of ABS and traction control, in bad weather (rain, snow sleet) conditions the drivability of the vehicle is severely compromised. I was made aware of the open class action suite regarding this flaw and have not left the truck for dealer service. Warning lights include ABS, traction control, and service electronic breaking.

ABS Light and Traction Control Light are both on. Loss of ABS functionality. The code displayed is C0020-01. The dealer has not looked at this vehicle yet but service will be scheduled with them.

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.

ABS LIGHTS COMES ON ANTI SWERVE LIGHTS COME ON HCU MODULE FOR ABS SYSTEM BAD THESE ISSUES ARE NATIONWIDE IN RAM TRUCKS ..parts are hard to get . Dodge should recall I’m paying out of my pocket.

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 $1500.00. 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.
