2018 RAM 3500 Complaints

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 system - flashes on and off dash, ABS has been inspected by dealership. Dealership said, could replace ABS but it could very likely have the same issue due to part malfunction. This malfunction causes- no cruise control, no traction control, sounding and lighting up on dash constantly.

Pulling a travel trailer in the mountains on vacation this month my Service ABS light started coming on and off intermittently and the alarm would sound each time. Each time my cruse control would turn off and I wasn't sure if my emergency ABS brakes were going to work, or not, if I needed them to pulling my trailer with my wife in the truck. I was 1,500 mile away from home and this created a stressful circumstance for me the rest of the trip. Upon arriving home, I discovered on the web that this is a know problem with Dodge RAMs of this year model. I also saw recall notices associated with 2018 models, just one year younger than mine with the exact same symptoms. Obviously, this problem didn't get fixed for the 2018 model year. I am quite concerned that my truck may not be safe and the ABS problem needs to be addressed. I am going to pay to have it fixed, but I feel confident that a recall notice needs to be executed, and executed NOW so others dont't have to die from a problem that was known and unaddressed.

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.
