2018 Ram 2500 complaints

My 2018 RAM 2500 has 30,176 miles on it. Two years ago the HCU and module controlling the ABS system failed and was replaced. When the system fails numerous lights and warning chimes activate and the cruise control stops working. The system has failed again and the dealer tells me it will take 45+ days to get the parts necessary to repair the ABS system. After researching online I discovered an open class action lawsuit against FCA for this problem. I also discovered that this is a common problem with 2500 and 3500 RAM trucks after reading owner forum sites but so far no recall has been issued by NTHSA. This is a major safety issue for owners and needs to be fixed.

The ABS controller on my truck has gone out for the second time. where do i take it to get RAM to fix this issue this? i paid out of pocket for this repair the first time. please advise.

Loss of ABS/traction control. Electrical failure ABS pump motor. Loss of braking ability. Vehicle has very low mileage, less the 3,000 miles.

ABS/BRAKE warnings and a Service Electronic Braking System lights on, related to Symptom/Vehicle Issue: C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE and Class Action Lawsuit Civil Action No. 4:22-cv-00447

My ABS and Traction Control lights go on and off while driving. It happens at different times and all different speeds.

Abs warning and abs in operational

Loss of power/turbo. I was hauling a heavy load when I had a loss of turbo power on highway. Causing my truck to loose mph up a hill and almost getting struck by a semi vdd into my trailer. Check engine light is on and turbo don’t kick on anymore. I haven’t had the money to fix the problem but I’m certain it’s the turbo/turbo actuator.

The ABS control module and the Hydraulic control unit are both faulty and need to be replaced. Parts are not available to fix this issue. Recently the truck's brakes have started randomly applying themselves so hard that it slows the truck down even while accelerating. I find this very unsafe.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the ABS and Traction Control was inoperable. The message to service the ABS and Traction Control warning light was displayed. The contact stated that the failure had occurred previously, and the ABS and Traction Control module was replaced. The failure reoccurred. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

The ABS light has come on in our pickup. We have no idea why it is on, or if it is something we need to worry about. I researched online and found that this has been a well documented problem with this year, make and model truck. Many complaints filed along with requests for a recall. We plan to use this pickup to pull our 5th wheel camper, so if this problem could cause issues with braking system, it could be very dangerous for us, as well as other drivers on the road.

Abs pump motor, hcu and module need to be replaced. Dodge knows this is a problem and they need to stand behind their product and recall these vehicles. The cruise control cannot be used, it surges trying to slow the vehicle down due to the faulty modules. The parts are on back order until June. This issue started at 46,000 miles but because the vehicle is over 5 years old Dodge doesn’t want to cover the repair. Not a happy customer! Please recall these vehicles.

A warning light appears and anti-lock brakes do not function. this is the second time for this same defect. The first time was as approximatley 40000 miles and now jusd past 80000 miles. The parts for repair are unavailable thru dealer and they said it probably be December before they got parts in. I now have no anit-lock brakes and no cruise control. It seems the cruise control circuit is with the anti-lock brakes circuit. This seems to me to be a real safety issure with all of these Ram 2500 trucks. The dealer knows all about it but cannot help.

My truck had warning lights come on in December 2023 saying to service the anti-lock braking system and the electronic brakes. I took it to a mechanic and I was told that the part would take at least 45 days to get. Now we're being told it will take 3 months to get because it is impossible to find. After researching this online, it is a nationwide problem for many Dodge Ram owners. These vehicles are out on the road needing this part to keep their brake systems from failing and it is impossible to get.

The ABS (anti-lock braking system) and EBS (electronic braking system) failed in the fall of 2023. I was told by the dealer that a new part could be ordered on 21-FEB-24. On 21-FEB-24, a new bulletin was released that indicated a new part could be ordered in JUN-24. This is ridiculous. When are you guys going to do something? How many near accidents, near accidents, etc. is required for you guys to rain on the Stellantis parade? These trucks are dangerous and they have been out of reliable service going on a year. Are you going to force Stellantis to compensate owners for the loss of their truck for close to a year or do you view this as BAU? I have to say I am completely disgusted by the apparent inability of Stellantis to properly resolve this issue. I am also disgusted that you guys have done nothing.

I brought my 2018 Ram 2500 to the dealership for the ABS light. I was told i needed to replace the ABS HCU and the ABS module and that old of the parts is not available to order until June 2024 Maybe. I am unable to get the truck inspected do to this issue.

The ABS service light keeps coming on and beeping. It will go off after a little while but then returns intermittantly while driving. Apparently this is a known problem and should be a recall. Many owners are wasting thousands of dollars for repairs that should be covered by a recall.

The component or system that is failing or malfunction is the ABS Hydraulic Control Unit (HCU) and ABS module. The malfunction is turning off my ABS and TCS system, making the vehicle unsafe to drive. Also the ABS and TCS dash lights are constantly dinging and going off and on distracting me while I'm driving. This issue is well know with the dealer. Here is a TBS from 2020: RAM TSB S2005000004 The vehicle has been inspected and and the ABS module was already replaced, but didn't fix the issue. This has been happening since I bought the truck.

ABS MODULE AND HYDRAULIC CONTROL UNIT ON A 2018 RAM 2500,HAVE REPLACED IT TWICE,ITS OUT AGAIN ,AND OUT OF WARRANTY.52K

My truck has right at 80,000 miles. Every so often I get two dash lights. One is ABS service and anti skid warning. They randomly show up. They pop up very quickly then go away. But it happens non stop. I have done some research and it seems that there is thousands of people with the same truck and year model with this same issue. I went to the dealer in Seguin, Tx and they told me that there was really nothing I could do to fix the issue, unless I wanted to wait eight months. But the new part rarely last. They flat out told me to not follow any one too close because hard braking could fail without anti skid working properly. RAM needs to make this right. I can’t believe that there has been this many people complain about a serious safety concern and nothing has been done.

My ABS light has started to flash off and on and states that I need to ring it in for service. my truck has just under 38k miles and when I first bought my truck I had to have the master cylinder replaced. The dealer quoted 1200 dollars to fix the ABS issue by replacing the HCU, and stated they are the only ones that can complete the repair. I see there there is a service bulletin related to this issue and when looking online this appears to be a large widespread issue.

For over a year and a half I have been without my ABS system due to FCA installing faulty ABS modules and hydraulic units in the 2017-2018 Ram 2500's and 3500's. The same units were installed in the 2019-2021 Ram 2500, 3500 but FCA recalled those models. I am also without cruise control as well. FCA has even put out a technical service bulletin about this and still has not resolved this issue.

The contact owns a 2018 Ram 2500. The contact stated while driving 50 MPH and when depressing the brake pedal, the ABS was inoperable and made abnormal sounds. The contact stated that the ABS and Traction Control warning lights were illuminated with the ABS failure message displayed. The vehicle was taken to the dealer where it was diagnosed with ABS brake module failure. The failure occurred on numerous occasions. The contact stated that the vehicle was not repaired due to parts not being available for over a year. The manufacturer was made aware of the failure and confirmed that parts were on backorder. The approximate failure mileage was 20,000.

I keep getting an Electronic Brake Service message and ABS message that randomly starts dinging and popping up on my display that also disables my cruise control. This obviously is a known issue and I would like to know what is being done to correct this. I have read several and seen over 3000 reports of this problem so why is it not being addressed to make our vehicles safer when it is a known fault. We travel with our camper and travel baseball all summer long and this is not acceptable when it comes to my family or the safety of others on the road around me.

ABS light is on and the ABS Controller has already been changed out twice. Its unsafe braking conditions for myself and the public especially in poor weather conditions or towing.

My 2018 RAM 2500 pickup displays these messages "Service Electronic Braking System" and "Service ABS Braking System". The cruise control and the Electronic stabilization system stop working when the messages displays. I am afraid to drive the truck as no ABS or electronic braking makes the truck unsafe to dive. The dealer says the HCU needs to be replaced but the replacement is being redesigned and is not ready. The truck has been parked for over a year. Why hasn't there been a recall on this issue? The truck is unsafe to drive.

The ABS module and Hydraulic control unit are faulty causing an intermittent activation of the ABS warning light and Electronic Braking warning lights. When the lights come on the cruise control will disengage, if set, and cannot be reset until the light goes out. The length of time the lights stay on vary from a few seconds to a few hours, to always on. When in park the light can be made to go off if the brake pedal is pressed excessively hard. There is an ABS error code stored which is C0020-01 This is a known problem with Chrysler as they have produced TSB #[XXX] for this issue. This is a known faulty part that could cause an accident due to ABS malfunction. I feel Chrysler should be forced to remedy this issue for all 2017 and 2018 Ram owners since it is a safety issue. My vehicle is a 2018 Ram 2500 Tradesman with less than 33000 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Hydraulic control units and anti-lock braking systems keep giving an error code.

ABS and traction control systems are inoperable. Dealer diagnosis in December of 2022, says ABS control module and Hydraulic Control Unit (HCU), are bad. Ram has failed to supply functional parts to affect the repair. It has been 14 months awaiting parts and Ram/Stellantis has no proposed date for when the parts will be available. I'm scared to death to tow anything (especially on wet pavement) without properly operating brake controls. This is dangerous condition and NHTSA should do something about it.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed with cruise control activated, the vehicle experienced a loss of traction control and brake performance. The cruise control then inadvertently deactivated. The Service Electronic Brake System message was displayed, and several unknown warning lights were illuminated. Additionally, the speedometer and tachometer dropped to zero while driving. The contact pulled over and turned off the vehicle, but the vehicle failed to restart. The contact disconnected and reconnected the battery to reset the vehicle. The vehicle was able to restart. The vehicle was taken to the dealer, where the HCU was replaced; however, the failure recurred. The vehicle was taken back to the dealer, where it was determined that the ABS module needed to be replaced; however, the part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The contact related the failure to NHTSA Action Number: PE22012 (Service Brakes, Hydraulic). The failure mileage was approximately 46,000.

The Antilock and Tracktion controll lights come on and off with a chime while driving. It also disables my Cruse Controll when it goes off.

ABS is not functional. HCU and ABS Pump are failing and there are constant service lights that come on. Is very dangerous and dealer claims part is back-ordered.....Extremely dangerous to not have proper ABS.....

2018 Ram 2500 has ABS and traction control light always on. Will sometimes go off and then come back on. I contacted the dealer yesterday [XXX] at Mcpeek in Anaheim, Ca and they told me opart is on back order. No recall. This is dangerous and I do not know if it will affect brakes and traction when I haul different trailers. Ram manufacturer should take care of this issue. Dealer also advised me they have been getting many complaints regarding this dangerous problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2018 Ram 2500. The contact stated while operating the vehicle, the ABS and Traction Control warning lights continuously flashed off and on or remained illuminated. Also, during the failure the cruise control became inoperable. The vehicle was taken to the local dealer who determined that the Hydraulic Control Unit was faulty and needed to be replaced but the parts were on back order from the manufacturer. The vehicle was not yet repaired. The failure mileage was 78,000.

Warning lights and audible warning for ABS and emergency braking along with traction control have been active for several months. Dealer determined the ABS control module is faulty and needs replaced. Current lead-time for the part is 7 months and cost to replace is $1,200. While the warning is active the cruise control and traction control are de-activated. During a recent rain storm I had to accelerate to avoid a merging vehicle on the freeway and the rear tires broke loose due to the lack of traction control and sent me into an uncontrolled fish-tail across 3 lanes. Fortunately traffic was light and everyone was able to avoid me and I got it under control and stopped just before hitting the freeway barrier wall.

Over the last several months my 2018 Ram 2500 is experiencing intermittent service abs traction control system issue. The lights on the dashboard will go on and off and it will "ding" when it does. I am very concerned from a safety stand point as I know this system is supposed to help with braking in an emergency and assist with keeping the vehicle under control in adverse road conditions. The truck only has 35,700 miles on it now. I have taken it to the dealership and they are not able to read any trouble codes. Thank you for any assistance with getting this corrected. Ram needs to recall this issue as I have done some research and have found this to be a very common problem with this year make and model vehicle.

The abs light and traction control light have been flickering for years. Now they are on solid. When I went to the dealer they said the part is under engineering review and they can’t fix it anyways. My truck now won’t pass safety inspections and can’t be reregistered

The vehicle has lost all antilock brakes Lights on dash warn there is a issue with vehicle safety capabilities. The trailer brakes will not activate. Dealer says common issues with 2017 2018 and cannot fix due to parts not available for a year. People are putting their lives in danger operating this truck with this issue. I have had work on this problem before costing thousands of dollars. I can't belive you let them effectively shun safety and lives.

The ABS module on my 2018 Ram 2500 has failed. It is throwing a C0020-01 code. As a result, the ABS and traction control safety feature are no longer working. The warning lights for both are displayed on my dash.

There is a failure in the brake system. Either the HCU or ABS module has failed. the cost of repair is in the 1500.00 range. I have since learned that this was/is a problem with this year of vehicle and a class action was started. I'm looking reimbursement to the repair. Dodge should be covering a known safety issue. I haven't repaired it yet

Warning light to service the Electronic Braking System came on. Has been intermittent since. Contacted dealer and the HCU needs replacing. Vehicle is under mfg extended warranty. They claim part not covered. There are hundreds of complaints about this along with a class action lawsuit filed last year in CA. Brakes may fail without repair. 4WD will not engage since warning light came on. Lawsuit alleges Chrysler knew of this defect before selling. I have scheduled a replacement of the unit for 3/1/2024

When hauling my 20' enclosed trailer with a 10k lbs load my 2018 ram 2500 turbo actuator went out. my exhaust brake is inoperable due to the turbo actuator not functioning properly. the truck does not build boost as it should. there is a service bulletin for 2015 ram 2500 with 6,7 cummins in them. bulletin number [XXX]. this bulletin covers the exact part that went out on my truck while hauling. the part numbers from 2015 to 2018 model years did not change. i have attempted to reach out to ram about this issue. they state that the part is different even though the dealership says it is the same. here is a link to said defective part.

The contact owns a 2018 Ram 2500. The contact stated that while towing a trailer at 55 MPH, the turbo actuator failed to operate with the check engine warning light illuminated. Upon investigation, the contact discovered Technical Service Bulletin: 09-005-22 which linked the failure to the turbo actuator kit. The dealer was notified of the failure and referred the contact to the manufacturer. The manufacturer was then notified of the failure and referred the contact back to the dealer to have a diagnostic test performed. The vehicle was not repaired. The failure mileage was approximately 130,000.

The truck last year started flashing the ABS and traction control lights. On the screen it says I have to service my braking system. As soon as that warning comes on, I lose traction control and it’s awful to dry in snowy or wet conditions. The truck just hit 28 thousand miles. I contacted the Ram dealership and they are aware of the issue but stated there is no recall so they’re not addressing the issue.

We purchased our Ram 2018 /2500/4WD Mega 6'4'' Larami in 2019. I only had 7,853 miles on it. When we drove the truck to Tenn, the Abs and traction control lights kept coming on the display. This kept happening throughout the trip. On [XXX] we had returned and taken the truck to Dodge dealership for inspection. They performed diagnostics and found Abs motor internal failure, this was replaced, and the brakes were bleed. The code was: C0020-01. The truck was still on warranty. On [XXX], once again we had the antilock brake system / Elec braking system light came on the display. Verified concern found Abs code module internal at this time rec replace of Abs pump. (Direct wording on invoice). Truck still under warranty. In Dec 2023, we returned to Dodge dealer again for constant display of the Abs traction control lights flashing on and off. We started videoing this to prove the problem had NOT been fully fixed. We were told by the dealership that the HCU part was not available till spring or summer of the following year. By this time, the truck is no longer under warranty. This problem is not only annoying, but the issue of safety is foremost. We don't drive the truck in the rain for fear of losing traction. We have a boat that sits there because we are concerned about stopping the load. This seriously needs to be addressed by the manufacturer. I have read several accounts of other owner experiencing the very same issues. I don't want to have to pay out of pocket for a problem t

The contact owns a 2018 Ram 2500. The contact stated that while operating the vehicle, the "Service ABS Electronic Braking System" message was displayed, and the vehicle would not immediately stop while depressing the brake pedal. Additionally, the cruise control failed to operate while the message was displayed. The vehicle was taken to the local dealer who diagnosed that the ABS Hydraulic Brake Module was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 2,000.

The Hydraulic Control Unit Chrysler part number 68143491AA failed and has not been replaced yet. This causes the Anti-lock braking system and Traction control system to no longer function limiting function under wet or slippery conditions. This puts the driver and others at risk. The vehicle/component has not been inspected by the manufacturer, police, insurance representatives or others. There were no Warning lamps/messaged before failure only after. These would be ABS lamp and traction control lamp plus a service ABS warning message. It flashed intermittently for months before finally staying on permanently starting a couple weeks ago.

The abs/traction control message goes off intermittently. The truck dings and beeps from the dash with a message that says “service abs”. This is a known issue with this yr/make truck.

Warning lights for ABS and Brake system flash on and off continuity while driving at any speed or stopped, with a message displaying "Service Electronic Brake System" and a warning chime. This typically occurs once every 2-3 seconds. Truck was taken to Local Ram Dealership in Early October of 2023 for diagnostics. Dealership stated issue was the hydraulic control unit causing the warnings, but parts were on hold for inspection by Ram so the issue could not be repaired. As of Feb 2024 the dealership has informed me the repair parts are still on hold at least until April 2024. The hydraulic control unit problem disables ABS, Traction Control Stability Control and Cruse Control systems.

The abs and traction control light come on. Failure in the abs module
