2018 Ram 2500 complaints

Intermittent ABS/Traction control light despite new ABS module and service at dealer. During heavy braking the Traction control does not function properly, causing unsafe driving conditions for myself and other motor vehicles on the road. Chrysler/Mopar have failed to address the issue.

Two years worth of "ABS" and "service electronic brake system" warning lights and bells going off. About 3 months ago they finally got a re-engineered ABS brake module installed and the light went away for about 2 months. Now they are back intermittently. Took it in to the dealership and they now say the HCU unit needs to be replaced as well. From reading RAM forums this is a known/on going problem with 2018 RAM 2500.

Hydraulic Control Unit & ABS Module. 2018 Ram 2500 4x4 Bought truck new, the HCU & ABS Module parts failed issuing constant alarms on dash. Parts were replaced in April 2021 under warranty with approximately 22,000 miles on truck. Now getting the same alarms again and dealer says the Hydraulic Control Unit has failed again. Truck only has 47,000 miles and are in need of replacement again. Looking this up online and there are tons of reports with the same issue on 2018 models. Brakes should be covered in a warranty or recall, IMO.

ABS LIGHT AND TRACTION CONTROL LIGHT FAILING AND NEEDING TO BE REPLACED

Electronic Braking System comes on and off after I hit a bump on the road. I am very worried about this issue. The dealer is not able to diagnos the issue unless it come on when I drop it off to them. This issues has been an issue for several months now. I checked online and several other Ram 2500 and 3500 owners are dealing with the same issue. Please help us do something about this.

The hydraulic control module and the ABS module are not working properly. This is a known defect on these trucks. When the lights are on, the ABS will not engage. I have had the truck at the dealer, and they said since there is no recall, they can do nothing. This problem was addressed in a recall for 2020 and newer trucks but not for 2018 trucks. I know of two class action lawsuits, one in Texas and one in California.

ABS does not engage in emergency stops. Truck has been reviewed by a dealer noting a surge of HCU and ABS units malfunctioning. Parts are on a year lead time in order to repair.

For the last few months, my ABS/Traction control lights on the dash board have been flashing on and off over bumps and even flat road driving. Over the last few weeks, the ABS/Traction control lights have been staying on constantly. I am nervous to tow a heavy load with these lights illuminated since this is dealing with the brake system. After some research, I have discovered this is a huge issue with the RAM 2500 and should be fixed by the manufacturer

Starting about a month ago, I started receiving a warning about servicing my electric brake system. Was very intermittent. Spoke to the dealership and they said if it wasn’t happening right then, they couldn’t read the codes. If the light went out, I could wait to bring it. Went on a trip, and it started happening more frequently, but still intermittently. I tow a 7-ton fifth wheel, which made me feel very unsafe. Sometimes happens moments apart, and sometimes hours apart, and it always knocks out the cruise control. Looking online, I found that this is a very common occurrence, and that I should report it. I did not have an accident, and tried to do my best to drive safely so I could get home.

ABS / Traction control error intermittent alert.

Loss of break performance. Traction control and abs warning lights come on intermittently. This is the second time this has happened. Had abs module and hcu replaced once already.

ABS/TRACTION CONTROL LIGHTS and alarm started in January 2022 the vehicle only had 21,460 miles on it so I took my 2018 Ram to dealership to get looked at and they diagnosed the faulty part as ABS HCU/MODULE. The vehicle was under warranty so they fixed it for free. October 01 2024 the same thing happened vehicle with 38,000 miles all the lights started flashing and alarming while I was towing my camper I've heard that when this happens it disables cruise control and the trailer braking system. THATS VERY DANGOUS WHEN PULLING A 8,000 POUND CAMPER!! Now I've heard that the part is on back order and 'm lost on what to do.

The ABS light will come on while I am driving along with traction control turning off with a ding. While the warning comes on, the cruise control will turn off. It will turn on and off several time during a drive and will ding when it comes on. Very distracting and annoying and distracting. the dealer will charge me to look at it to find a reason. Truck has 37,000

Abs light and traction controllight on

Traction control light and ABS light come on and go off intermittently will cancel my cruise control.A warning ding accompanies this.It does this frequently while driving.Electronic braking warning comes on the dash.

On 10-01-2024, I took my 2018 RAM Truck for service at the Warrensburg, Missouri Dealership. The reason was due to service lights coming on in the truck to tell me the ABS and Electronic Braking System had issues. The dealership service department replaced a faulty HCU and the "Control Anti-Lock Brake System". My truck had 69850 mileage when the service lights came on. This is the second time, the HCU has been replaced due to the same issue in 04-21-2021, when the same truck had 30945 miles. The dealership explained this is due to RAM contracting the HCU part from a manufacture that proved to be bad. They have now changed manufacturer and the new part is being installed. A quick search through the internet shows this is an issue in RAM trucks over the years with two lawsuit in two different states. The loss of the braking systems, especially when hauling trailers and campers can cause serious braking issues. Why has there not been a recall issued on this HCU? Not only unsafe, but not being warrantied by RAM, my repair bill for their error in manufacturer, cost me almost $800.00. Please investigate before a serious accident occurs over many years of these RAM trucks using a faulty HCU.

The ABS system lights and dinging keep going off. Started months ago. Stopped for a while then does it randomly sometimes a lot, sometimes once in a while. Theirs is no rhyme or reason why or when it dies it. Stopped at dealer and they said this year was having problems and they have been back ordered with parts and have no idea when they will be in.

Currently I own a 2018 RAM 2500. I am the original owner and do regular Maintenace on my truck. The ABS & Traction control light flashes on and off consistently (Very annoying while driving). I have brought my truck to the mechanic and told me I have to wait on a part that is on "National Back Order".... No dealership has the part, and no website has the part. Only place to be found is on eBay used with no warranty they work, or proof they have been refurbished. From what I have been told it is the EBCM. I did research to try and find the part. No where has it, and nowhere to be found. This is where I found out it is a frequent problem over a lot of people. I see RAM has a recall for the same issue with 2019 & newer, but no recalls on the 2013–2018-year model trucks. This truck is my everyday driver, and I need it fixed....

ABS and TRACTION CONTROL warning lights appear and disappear. Timing of warning lights have no discernable pattern. Vehicle has had no collisions and only 120,000 miles. Vehicle will be going in for inspection at garage.

In reading all the forum ABS and traction control fault. Comes on and off depending on speed and hit any bumps in the road. Looks like there is open recalls but none for 2018 RAM 2500 Diesel. This is a safety issue and could cause a massive accident. Cruise control will not work when sensors are on.

While driving the ABS light and traction control light come on and go off randomly. I am afraid the brakes will quit working.

Anti-lock Braking System module failure due to poor/defective manufacturing and/or parts. This is a known issue with 2018 RAM 2500/3500 trucks. Safety is at risk due to failure of the ABS module which affects stopping performance. The RAM delear has diagnosed the issue as intermittent. The warning lights go on/off constantly while driving causing a distraction as well. This part should be recalled.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the ABS warning light illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the ABS control module. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 45,000.

My ABS light and ESC light come on intermittently and at time repeatedly on and off. Also a warning comes on stating either "Servcie ABS" or "Service Electronic Braking System". There are no codes when scanned.

When driving around a bend in the road regardless of left or right bend, once the steering wheel is turned between 45-90 degrees, the steering wheel moves back and forth from left to right on its own. Also when sitting still, with the vehicle running, if you turn the steering wheel in either direction between 45-90 degrees there is "play" in the steering wheel of approx 10% without moving the actual tires. There has been no modifications or accidents to the vehicle.

While under warranty (no paperwork available for exact date), the ABS and Traction Control warning light would intermittently turn on and then go off. It was taken to the dealership and repaired under warranty. I now have 40,000 miles on the truck and am again having the same issue.

ABS light comes on, antil lock brakes no longer work and Cruise inoperable. The ABS/HCU module has gone bad again, the dealer has replaced it 2x already. This is the third time it has happened and vehicle has 25989 miles. Dealer states this is a KNOWN issue and parts to repair are unavailable,.

I purchased this truck new in 2018. I soon started having problems with very hard shifting and slamming into gear. It has been to the shop and diagnosed and continues to do it. They cant seem to fix it. My ABS lights and alarm are sounding non stop. This happened within 5 miles of my warranty being up. I did diagnostics and they wont cover it and want to charge me 1500 plus i have to wait 8 months for the part. This is an ABS issue and a safety issue! I also get the DEF failure notice telling me its going into limp mode. This has happened multiple times. I still only have 36k miles on it. I was told this ABS issue was now covered and the factory is doing extended warranties based on these problems. But the dealership says they know noting about it and that i have to bring it back in AGAIN to diagnose which i have to pay for AGAIN. I hate this truck and i have had nothing but problems and no one will help.

The rearview mirror backup camera display intermittently does not turn on or disappears while vehicle is in reverse. Yes. Could cause significant risk to others outside the vehicle while backing up if not seen in other mirrors. I have sent the truck in multiple times to multiple dealers but it is intermittent so they were not able to recreate the problem while in their possession. Only inspected by the dealership. No warning lamps or messages or other issues prior to the display not showing. I first noticed the issue the first week I purchased the truck (2022). I have a video of the issue for proof but this form will not allow me to upload.

The hcu control unit keeps going out, fixing to be replacing 5 one on this truck. Lost all cruise control, and 4 wheel drive functions.

ABS AND TRACTION CONTROL LIGHTS APPEARED ON DASH PUTTING SYSTEM INTO DEFAULT MODE , APPEARS TO HAPPEN ON AND OFF AT WILL,

Abs module/motor failure. Second time at 60000 miles also failed under warranty and replaced at that time.

At approx 24K miles my RAM 2500 had an intermittent anti lock brake/ stability control malfunction and displayed a "Service Brake System" message randomly while driving. The issue was "fixed" under warranty. Currently my RAM has 54K miles on it and the issue has reappeared. I know their is a safety recall that exist for 2019 and newer trucks but believe the problem may exist on trucks built prior as well. Either way, an intermittent anti lock brake/ stability control malfunction seems to exist on the 2018 models, and based on info posted on RAM forums, it is a common malfunction.

ABS light and traction control keeps coming on. Dealer says there is no recall. If you look through the Internet, you’ll find thousands of complaints of this issue. I find this to be a major safety problem, I haul a heavy trailer with this truck and if my ABS and traction control fails, this is very dangerous.

When driving the ABS and Traction Control caution lights illuminate. I went to the dealership and they said it was a bad ABS pump and was a little over $1200 to replace. The truck only has 24k miles on it.

My truck throws a abs traction control failure code. This happened in 2022 and was fixed by the dealer because my truck was still under warranty. The hydraulic control module was replaced and the abs control module was replaced. I have just received the same error lights on my truck again on 09/27/24. My abs and traction control are disabled. This has to be a faulty design or bad part. My truck is now out of warranty. There is no way this issue should have happened twice on a truck this new unless MOPAR is making or using bad parts

See attached document for complaint.

Receiving the "Anti-lock brake system Warning" comes on frequently. Once cleared, the sensor or module either fails again, or provides the erroneous warning. Happens frequently, at least once every 1-15 miles, whether vehicle is moving or not. Dealer mechanic says this is a known problem with 2018-22 Ram trucks. New replacement modules are not available, and those who have had them replaced reported reoccurring problem within a year.

ABS failure which also turn traction control off. My safety and the public in general is at risk if my brakes lock up on a slippery road, especially if towing. The problem was confirmed by my mechanic, parts are impossible to get. Tons and tons of complaints online and in forums.

ABS lights come on in dash and cruise control shuts off. Diagnostic found ABS HCU and ECU faults.

Service electronic braking system / service ABS light comes on and off when driving on on bumpy roads and when turning. It usually stays on which disables traction and it has cause me to almost spin out when accelerating in wet conditions.

Abs module failure causing cruise control shutdowns and potentially causing an accident as well as transmission issues. Yes it’s been confirmed by an independent shop . Not by any others. No warning before just straight failure. Vehicle is available currently for inspection if wanted

Thai dang ABS going out in these trucks. And still no fix. Went out when going down the high way. Kicked out Cruze co trip 4 we and all sensors. Almost died this is crap that nothing is being done to fix this and get a part that fixes this for the customers that bought these trucks. I have a 50k truck I can’t drive. Have not driven it’s in almost a year now. SOMETHINGS NEEDS DONE

Abs mod and pump wet bad around 30,000 miles. I replace both and now 2 years later and 52,000 both parts are bad again. Looks to me there is a problem they haven't fix and keep selling parts that they know is going to fail. This is not a cheap fix and something needs to be done about it

Truck is experiencing a what started as a intermittent and not constant failure of the ABS and Traction control with flashing lights and constant chimes. Making the vehicle dangerous to drive.

Internal fault in hydraulic control unit. They are replacing this when the part comes in. Have no antilock brakes or cruise control. If that doesn't fix it, then they will replace the module.
