The ABS system failure and traction control lights came on and have been coming on intermittently. This failure has caused the vehicle not to retain cruise control and brake and stability control being reduced or potentially off could result in an accident. Upon research, this is a very common and costly issue not covered by warranty work, this seems to be something Ram should fix as it is a safety issue.
2018 Ram 3500 brakes complaints
Page 10 of 23: complaints 251 to 280 of 668, newest first, as owners wrote them.
ABS and Traction control failure. Code C0020-01. Occurs at various speeds and while stopped.
The component that failed was a brake module. It caused the loss of ABS and TCS. The part was claimed to be on backorder, and it took seven months for the part to be replaced. This forced me to drive an unsafe vehicle.
ABS and Electronic Braking control modules have not been working for 13+ months. Originally diagnosed by dealership July 2023. Been trying to get RAM / Stellantis to fix it. Been told parts are back ordered or not available due to re-engineering. Have heard there are hundreds of trucks impacted at each dealership. Why hasn’t there been a recall and why is RAM not helping me to get it resolved? Another call with them today 8/13/2024 and the dealership just needs the approval for cost for the HCU and RAM Customer Care is not responding and when they do, it takes days and no resolution.
The contact owns a 2018 Ram 3500. The contact stated that while starting the vehicle and while driving at various speeds, the service ABS and brake system messages were displayed. The contact stated that the failure recurred intermittently. The dealer was notified of the failure and informed the contact that the failure could be related to the HECU. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 52,700.
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.
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. Working to obtain timing on resolve to predict allocation and shipment to DLR to fulfill No firm ETA to provide at this time. 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.
Abs lights started flashing on and off rapidly. Had same issue fixed at dealer 40,000 miles ago and now it started again seems like a money racket or something now I’m quite scared to drive it if the brakes was to lock up it could be bad
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
ABS and HCU are defective , loss of braking ability in the vehicle and braking ability on the travel trailer. unable to stop in adequate distance when pulling 12000 pounds through mountains putting others at risk of collision had vehicle in for repairs three different times since 2019 ABS light luminates when system fails had vehicle in for repairs on 10/19/2020 , 2/5/2021, 6/20/2024, 7/18/2024
Abs / hcu has malfunctioned again, has already been replaced once around 20,000 miles now I’m around 58,000 miles and having same issues. Abs and traction control not working. In a truck with this much torque it is a serious problem. This is a well documented issue with the system and FCA should make it right. I found a video on line that explains the issue is with the brushes on the motor being held in to tightly. Should be a simple solution and is obviously a design flaw. There should be a safety recall asap. I assume that this problem happens with most of the heavy duty trucks.
ABS braking system, electronic braking system warning light and signal is coming on every few seconds when driving. This renders the cruise control to shut off when it comes on. There are numerous safety issues with this coming on and off not to mention it is annoying as…..well let me just leave it there. Have talked to dealers (2) and have been told that dodge has a fix but the parts are still on back order. I have been having this issue for about 6 to 7 months and it is making the truck undrivable for any distance at all due to the nuisance alarm every mile or so.
Abs service light stays on and dings. service electronic brake..
The message “service electronic braking system” and service antilock brake system” periodically displays on the driver information screen. If I’m using cruise control when the message comes on the cruise control abruptly disengages causing a lurching slowdown. Often times it chimes and the message displays and disappears and comes back on and off numerous times.
It appears that Ram years 2017-2018 have a known problem with the ABS pump. I have my 3500 ram in the shop now with only 30,000 miles and they are telling me the ABS pump needs to be replaced at a cost of roughly $1200.00. It is my understanding that there is a class action lawsuit and wondering why these vehicle have not been re-called? Major safety issue!
Vehicle was purchased used in Feb 2024 with 77000 miles. As I was leaving the dealer (Carmax), gauge cluster lit-up with Service ABS System and chimes. Spoke with dealer and they said to take it to Ram Dealer for diagnosis. Unit was diagnosed as needing a new ABS electronic AND hydraulic control module. Dealer was unable to get parts due to issues with FCA and parts not being available. Parts were on backorder until June 204. Continued driving vehicle, with ABS light coming on/off and ABS intermittently working and not. In June 2024, spoke to Ram Dealer, and FCA is saying I have to get the Electronic module replaced first. Ram Dealer replaced this on Friday 6/21/24 and things seemed fine. About 50 miles after picking up the truck (Saturday the 22nd), while towing my 20000 pound trailer (with my wife/kid/dog inside) the vehicle started losing power while on the freeway. I was able to get the vehicle to the shoulder and the hydraulic brakes on the truck were fully locked up. I had to put the vehicle in 4-lo to overcome the brakes to get the truck separated from the trailer so it could be towed to the dealership. The dealer has 3 other 2018 ram trucks on their lot with the same issue.
ABS/Service Electronic Brake Control and Cruise Control lights constantly flash and chime while driving. Have been told that replacements parts have been on back order for over a year now. Any help will be appreciated.
The vehicle is displaying a "Service Electric Brake System" message indicating failure of the HCU and ABS system and possibly affecting stability control. There is a lengthy history of this issue with the 2500 and 3500 trucks but no fix, resolution or recall appears to be available for this issue.
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.
I have been receiving an error for my electronic braking systems and ABS since July of 2023. I have been to various dealerships to have it fixed and have been told it is on a "galactic back order" - words from Dodge to the service advisors. I have attempted several times to contact Customer Care at Dodge over many months. My cases have been closed without resolution and with false promises of management will reach out to assist me. All I need is the 2 parts to be replaced so that I can use my cruise control and not have the constant dinging of the warning for the ABS and EBS. It has been very annoying and if there is such a large back order with others having this same issue, how come there is not a recall? It is the braking system.
The contact owns a 2018 Ram 3500. The contact stated while driving at an undisclosed speed, the Electronic Braking System warning light illuminated. The vehicle was taken to an independent mechanic who diagnosed that the ABS module needed to be replaced. The vehicle was taken to a local dealer and the contact was informed that the parts were on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure; however, no assistance was provided because the vehicle was no longer under warranty. The contact requested to buy the parts to repair the vehicle; however, the manufacturer refused to sell the contact the parts. The failed mileage was approximately 160,000.
My anit lock brake warning keeps going on and off
Abs module keeps on going out in many rams from 2500 to 3500. Making a alert sound about every 3 seconds making distractive driving I am currently #28 in line for the part in a small town and it's been 2 months now. They need a recall on this. They are being negligent by not saying there is a problem.
