2018 RAM 3500 Complaints

HCU / ABS system failed at 34,000 miles resulting in the ABS system and speed control system not working as designed. It was a costly repair not covered under warranty however it needed to be repaired as not having the braking system working as designed was unsafe. This is a known issue with the 2017 and 2018 RAM heavy duty trucks. This unit was recalled on newer models however the the 2017 and 2018 models were not recalled resulting in an expensive required repair.

The ABS light intermittently comes on/off. It pops up while driving, but goes away. Sometimes it goes on/off several times on short drives. I need to know if this is going to lead to an all out failure of the braking system or something else. I confirmed with the dealer, where I purchased the truck, that it's a known issue and the part is on national backorder. Based on my research, this appears to be a common issue with Dodge Ram trucks built between 2017 and 2021. I need to know what my options are since I plan to purchase the needed part(s) at my expense since my family's safety is at risk.

The ABS warning system is constantly going off with dash warning lights and alarm, it turns off cruse control when this happens. The truck is unsafe with out the abs working and dangerous because it will turn off the cruse when the error is displayed causing unexpended deacceleration. This happens when ever the veh is driven over and over. I took it to the local ram dealership. They told me that they can not figure out what the issue is......They told me I have to leave the truck at the dealership for a week at my expense (gas and insurance and they would not be responsible for damage) so they could drive it around and "test" it they were very unhelpful, they said they never ran across this issue prior. They were very stubborn on the actual issue and would not answer questions In the mean time the dealer attempted to sell me an oil change and oil filter change for close to $1000.00 that they were very insistent on. (with less that 3000 miles on the current oil and filter change) so this was unneeded. They were using the fault to upsell service and no attempt to correct it.

The contact owns a 2018 Ram 3500. The contact stated while driving at an undisclosed speed, the ABS warning light illuminated, and the cruise control failed to activate. The dealer was contacted and stated that the failure was a known issue. The dealer stated that the ABS Control Module needed to be replaced. The vehicle was not repaired because the part was not available. The contact was placed on a waiting list. The manufacturer was not made aware of the failure. The failure mileage was 67,500.

Service antilock braking system and service electronic braking system along with traction control light and message flash on and off intermittently. Have had mechanic look at it and was told dealer would need to see it. Have been on a few online forums and this seems to be something that many people have had issues with. Is there any kind of recall I’m missing on this issue? Thank you

Repeated, intermittent warning to service electronic braking system and service antilock braking system, both of which cause the cruise control to disengage. On multiple occasions, the disengagement of the cruise control has nearly caused me to be hit from the rear. Multiple forum posts indicate that this is a common problem.

Radio and back camera intermittent since I bought it new. Dealership changed it out several times and told me they are just bad radios and just wait until a recall is issued.

We receive a ABS/ECS, electronic brake control warning intermittently. This also makes the cruise control shutoff. We had the ABS control module replaced once at roughly 12000 miles under warranty but it now is giving the same warnings and the truck currently has 22000 miles on it. My dealer stated this was a known issue and stated it’s fairly common on my model truck

I have a 2018 RAM 3500 with ONLY 20,000 miles on it. ABS and HUC critical parts are faulty, and I have no way to even purchase one until a recal is issued. Class Action Says 2017-2018 Ram 2500, 3500 Equipped with Defective Anti-Lock Braking Systems. No current part that resolves this issue. Ram 2500 and 3500 pickups are unsafe because they’re equipped with defective hydraulic control units (HCUs) and anti-lock braking systems (ABS). RAM knows about it and has ALL the modules on engineering hold. These parts have not been available for almost a year. No antilock brakes. No traction control. No cruise control. 4X4 four wheel drive system is locked out and cant be engaged after this warning occurs. Here's what they are telling customers who have filed with them about this. Good Morning Mr xxxx, As of 06/26, No new update Part: 68228991AD Module Order: xxxx Per CLIMS: Part STOCK is under QUARANTINE pending quality / engineering review and inspection.

Pending response from SPLR / PKG Working to improve xxxxx Case Management 844-378-0575 Ext:4063199 My dealer said, be lucky if they ever have parts for a permanent fix. I can’t haul anything or use cruse control. Error lights keep popping up sporadically with dinging sounds, driving me crazy. It is "Service Electronic Brake System" with continuous ABS and STC fault warnings. This truck is dangerous to drive, a recall is a NO BRAINER!!!! I am writing for three reasons. 1. You need to get our dealer the parts now so we may have a safe vehicle, or 2. replace this truck with a new one if you cant repair ours ASAP, and 3. To make sure I have this all documented in case of any serious accident where you will have to assume all liability and responsibility if this occurs due to your lack of ability to repair this safety system.

The contact owns a 2018 Ram 3500. The contact stated that while operating the vehicle, the ABS and traction control warning messages were displayed, and the cruise control feature became inoperable. The cause of the failure was not yet determined. The manufacturer and local dealer were not yet notified of the failure. The failure mileage was 6,000.
