I was driving down us 19/27. The road was wet and a deer ran out in frount of me. When I applied brakes my tires locked up and I skidded of the road. My ABS light stays on and every time I take to the dealer to have it fixed they tell me they can not get parts. The truck has been doing this since I first bought it. At first it was intermitten but now the ABS light stays

Consistent warning stating, "Service Anti-Lock Braking System" and "Service Traction Control System" from the vehicle. While this warning is indicated by dinging tones, text displaying in the vehicle information screen, and lights lit on the dashboard, the ABS, Traction Control, and Cruise Control Systems do not function. This is a severe safety risk as if this occurs while driving your cruise control immediately shuts off and if driving in slick conditions you no longer have anti-lock brakes, nor traction control. This is apparently a known issue of Fiat Chrysler on the 2017-2018 model year vehicles where the HCU (Hydraulic Control Unit) needs to be replaced which will remedy this issue. The parts however seem to be in very short supply and not all vehicle mechanics can make the repairs as I am being told you need specific software to reset the system once the HCU has been replaced. This is estimated to cost between $1200-1800 to have repaired. I have reached out to Chrysler Cares and they advised me to take my vehicle to my local dealer for repair and advised there is no warranty, nor recall in place to cover these costs.

My 2018 Ram 2500 6.4l is experiencing intermittent ABS, traction control, electric braking warnings on the dash which affects cruise control once alarm is active. This issue seems to be globally.

- Suffolk, VA, USA

ABS light turned on on the dash. Next a warning that the park sense, ABS, four wheel drive, and Cruise were disabled. Had Diagnostics run and found that the vehicle ABS is logging C0020-01 and C0020-16. Case number S2005000004 from STAR showing this to be a known issue. Contacted every dealership within 100 mile range and the needed part of an ABS HCU is unavailable until at least February 2024. Contacted Stellantis Customer care and they will not assist unless the vehicle receives an official diagnostic from a dealership that will cost me at least $150 and they will not assist with replacing the part or even supplying the part so there was no gain from having the diagnostic officially done at a RAM dealership. Well known issue per every dealership and many online forums. No assistance from RAM/Stellantis at all.

ABS / Traction Control turns on and off intermittently without warning when this happens the cruise control turns off creating sudden loss of speed control

- Allyn , WA, USA

Hello, I have been having issues with my 2018 Ram 2500. The Service Traction Control and ABS lights on the dash have been flashing on and off constantly. Along with no Cruise Control when this happens. This has been going on now for about 3500 miles. I am still driving the vehicle due to being my only work truck. I have been doing some research along with talking to the Ram Service Departments and have noticed that this is a very large safety problem that is highly known about that is not being taken care of. Even the service manager I had spoken with is amazed that this has not been a recall. This should most definitely be a recall and should be taken care of before more people get injured or killed.

Vehicle: 2018 Ram 2500, mileage 35171. Beginning in April 2023 the ABS and Traction control dash lights would intermittently flash while sounding an alarm. The message on the dash states "Service Anti-lock Braking System" and "Service Electronic Braking System." This creates the issue of losing ABS and traction control while disabling cruise control. As time progressed it would become more frequent and would more prominent during extremely humid or rainy weather. First call to dealership was told "We can only diagnose IF the vehicle is demonstrating the issue." At that time I indicated to the service tech that there are numerous national forums with the exact same issue. Truck was brought to dealership for official diagnosis: $179 diagnosis fee; $411.70 Labor to remove and replace HCM; $262 HCU (Part # 68143491AA); $447.50 labor to remove and replace ABS Module; and $388 ABS Module (Part # 68347098AB). Service tech advised me that all parts are on back order and I could possibly be without the truck until mid/end of August. This is an issue the manufacturer should be obligated to correct.

ABS & Traction Control warning off/on on irregular basis Turns off cruise control each time the warning lights activate

- Plainview, MN, USA

The anti-lock braking system will fail intermittently which disengages the cruise control and traction control system as well as cause an audible chime. When this occurs, it may happen once or many times over the course of a few minutes, stop, start again, or stop altogether to reoccur a few days later. The issue appears to be the ABS control/hydraulic control unit issue others report. Loss of anti-lock brakes is a concern in itself; however, trucks in the class of a Ram 2500 are regularly leveraged as tow vehicles. Losing anti-lock brakes and traction control while towing increases risk significantly. In addition, losing cruise control coupled with simultaneous warning lights and chimes creates a significant distraction for the driver which under difficult driving conditions may prove dangerous.

This is the second time the antilock brake control module has failed and this truck has less than 75k miles on it. The warning lights constantly come on and off and if I needed to brake I am not sure that my antilock brake system would work.

My vehicle has intermittent ABS/Traction Control/Service Anti-Lock Brake warnings. Upon trip to the dealership they notified me that I had codes for active wheel speed sensor and a stored Anti-lock Brake Module fault. Upon repair of the Wheel Speed Sensor, I had a reoccurring fault of the same and all ABS/Traction Control/ Service Anti-Lock Brake warnings and the same wheel speed sensor fault. They informed me that they could not order the ABS Pump Module as it was on engineering hold because of an investigation by NHTSA. Please make these people recall the ABS systems on these vehicles as when I look for information it is happening to hundreds if not thousands of trucks. My truck has 125,000 miles on it and has been WELL kept, and Mopar/FCA will not even sell us the parts to make our vehicles safe again. Currently due to the fault I have no cruise control, no four wheel drive, no parking sensors, and NO ABS OR TRACTION CONTROL. Seriously dangerous. Thank you.

6 months ago, the ABS brakes and stability control warning lights started to randomly light up on the dashboard. Sometimes I would not see a repeat of this for a week or more. The warning lights started to appear more frequently, and now are on all the time. When on, the cruise control does not operate. I took it to a Ram dealer near me, and the service department confirmed it is a defective ABS pump, known as the HCU module. They then informed me that Chrysler has no inventory of this part! I asked how long to get one, and was told some people have been waiting for over a year! The part, # 68143491AB, appears to be readily available online from a multitude of vendors. My truck has only 34,000 miles on it, and no ABS, no Stability control, and no cruise control is a safety issue! Please HELP!

Consistent and predictive Failure of Anti-lock brake control module (68143491-AA /68143491-AB) in 2018 Ram 2500/3500 Trucks. Nationwide shortage of OEM Replacement Parts leading dealers to hoard exclusively for customers for whom repairs are to be made. Extremely difficult to find a dealer willing to sell brake control module, if they have one in stock, to anyone. Instead, dealers recognize there is up to a 6 month waiting period for restocking and therefore taking advantage of those who chose to utilize independent mechanics. Dodge/Ram is acutely aware of shortage, as well as failure of part and has chosen to not warranty or conduct a voluntary recall. Every Ram mechanic and parts office I spoke with acknowledge EVERY 2018 Ram 2500/3500 will fail. The subject vehicle had under 31,000 miles. During failure, the vehicle loses its' anti-lock functions, traction control, defeats cruise control, dash continually lights up with error message 'SERVICE ELECTRONIC BRAKING SYSTEM' then 'SERVICE ANTILOCK BRAKE SYSTEM' while simultaneously and constantly generating an audible warning over and over again during the operation of the vehicle. Price gouging for part, if you can find a dealer that 1) has the part in stock, and 2) willing to sell the part can run between $180.26 - $525.02 (MSRP $262). Part is in use for year models 2012-2018. I personally paid $525.02 (and grateful a dealer sold the part to me over the objections of the parts manager), drove 4 hours to obtain, plus install.

2018 Dodge Ram 2500 with Cummins turbo diesel. When driving, the dash warning light for the ABS and the Traction Control System intermittently come in and spontaneously reset. If the cruise control is on and set, it turns off without driver input. Dodge dealer states that the hydraulic control unit needs to be replaced, but they have been on back order for over a year.

Abs and traction control indicator lamps have an intermittent flash and alarm that alert at random times. This is dangerous as this not only disables the cruise control but the traction control is then disabled as well as the abs system causing brakes to lock up. Mopar and ram refuse to fix the issue and it costs consumers $1200 for parts and labor that may or not fix the issue. This is reported in many forum pages as well with all having the same complaints and stuck with the repair or not due to unreasonable cost associated with a possible fix. This should be an immediate recall as it is a safety concern even more so than an airbag issue. I cannot fathom a government agency responsible for safety to not mandate this as a recall.
