The ABS light came on and went off intermittently, which also disabled the cruise control when the light was on. Eventually the light stayed on. Most recently the start button quit working properly. We have had it at the dealership twice with no results. We have talked to the dealership many times and been getting the run around. The latest was today and was told the parts are back ordered until 2024. They have not given us any paperwork because we do not have to pay. We also have and had the radio (main computer) replaced a couple of times and the screen still blinks randomly.
2018 Ram 2500 acceleration complaints
Page 9 of 13: complaints 221 to 250 of 342, newest first, as owners wrote them.
ABS/traction control sensor issue. I believe it to be a faulty sensor or sensor connection issue which is causing my service brake light to chime and light up at every bump in the road. While driving even just a short distance my service brake light/alert chime goes on and off sometimes every 2-3 seconds and while driving on the freeway my cruise control disengages every time the brake warning pops up. Upon researching this issue I've found thousands of Dodge Ram owners complaining of the exact same issues and dealerships are suggesting they know nothing about this problem.
ABS/traction control failure. This also disabled cruise control causing rapid deceleration at set highway speed. Getting repeating chime and check ABS and traction control warning messages. ABS module and HCU were replaced under warranty at under 11,000 miles for same symptoms. Truck now has just over 45000 and read ABS codes indicate that part has failed again. Part seems to be backordered or unavailable from dealers.
ABS and Electric Braking System - multiple failures.. 1st time system failed at around 24k miles, was reported and fixed under warranty, 2nd time same system failures at around 76k, same errors and same results.. will have to be repaired under owners costs.. Seems this is a 'known issue with a NTSB" but Ram still not owning the issue.. This part plays a huge role in the safety controls of the truck.. They are designed and built to pull heavy loads and the braking and traction controls play a huge role in the safety traveling of these vehicles..
ABS , traction lights are on and cruise control , ABS and traction control doesn’t work. Safety issue. I understand that there is a recall on 2019 , 2020 models and wondering why the 2018 ram 2500 are not included in the recall .seems like a common problem says the dealership.
ABS module or HCU bad. Anti lock brakes not working. Cruise control not working. 4WD not working. Caused issue driving with a load when ABS did not engage and almost rear ended another vehicle.
C0020-01. Electronic Braking System and stability control system continually go in and out of alarm kicking the truck out of cruise control suddenly. This was repaired once under warranty by replacing the hydraulic control unit at 40,000 miles and it is now doing the same thing again at 90,000 miles. This is a significant safety issue as it prevents the use of cruise control and turns off the stability control system on the truck. The parts to repair the system are not available due to them being in “Engineering Review” until 2024. The only guidance from Ram was to continue driving the vehicle until parts become available.
The contact owns a 2018 Ram 2500. The contact stated while driving at various speeds, the ABS and stability control warning lights illuminated and flashed on and off. There was an abnormal dinging sound heard. The cruise control became inoperable. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, who stated that the vehicle had displayed DTC Code: C0020-01. The manufacturer was not contacted. The failure mileage was approximately 60,000.
Similar to the 2019 & newer Ram HD recall for the ABS electronic control module, my 2018 Ram 2500 has the same issue. It was recently diagnosed at the dealer in August 2023, but due to the abundance of impacted trucks, the dealer estimates that replacement parts will not be available until at least February 2024. While I wait for the repair I have no ABS, traction control, stability control, or cruise control. I drive the truck approximately 750 to 1,000 miles per week and have a 3,000 mile vacation planned in October. This translates to driving the truck approximately 15,000 to 20,000 miles without the above noted safety features. I believe my truck should be added to the recall, and RAM needs to step up and provide faster repairs.
For the third time in 37000 miles the abs system including ABS system and electronic brake system has failed. This has been repaired around 15000 miles and recently at 35000 and it went out again at 37000 miles. Didn't last 2500 miles after last repair. When this happens trailer brakes quit functioning and cruise control also quits working as well as every few minutes the system gives you a continuous warning chime. From checki9ng a few web sites this seems to be an on going problem on the 2018 trucks mostly but a few 17s. Last info I have is parts are not avail for repairs until at least 2/24 and then only maybe. The truck is unsafe to drive especially when towing a larger trailer. This needs to be made a recall for safety concerns. I had to trade off my truck due to how I use it and no expectation for a repair time or date.
Abs traction control braking issues and danger. Only has 24k miles garage kept
Antilock Brake and Traction control warning lights alert with dashboard message intermittently notifying to "service electronic brake system" and "service antilock brakes". Warnings come and go and may stay off for several days. When in warning mode, cruise control is de-activated; either shutting off, if set, or not allowing use. Dealer repaired by replacing pump control module (part#68143491AB) at a total cost of $683.19 for parts and labor. Odometer mileage at time of event was approximately 76,600 miles. Dealer indicated that this was a very common problem. Truck should be recalled and repaired at manufacturer's expense.
Vehicle started displaying “Service Electronic Braking System” and “Service Anti-Lock Brakes” intermittently and rapidly, during normal driving. Problem appears at random, and when it happens, the cruise control cuts out causing loss of speed. Truck shows code C0020-01 with an ABS code reader, meaning that either the Hydraulic Control Unit or Anti Lock Brake Module (or both) require replacement. Upon researching repair, I have found that this is a very common problem with these trucks, and that there is a possible the federal safety agency investigation into this, as Ram is very aware of the problem (as evidenced by their responses on forums discussing this problem) but has not issued a recall.
My ABS and Traction control lights activated visually and with audible alarms. I brought it to the dealer. It only has 23,000 miles on it with a manufacturer extended warranty. The dealer told me that the ABS pump motor control as well as the HCU has failed and need to be replaced. They also told me that the parts are not going to be available until the EARLIEST February of 2024. The vehicle is not safe to drive without these safety systems working especially towing. They told me the parts are under Engineering review. They suggested I park the vehicle until parts are available. NOT ACCEPTABLE!!! I have looked at owner forums and this issue is common and needs to be addressed by the federal safety agency and the vehicles recalled due to safety.
Service electronic braking system light comes on intermittently every 1-5 minutes while driving. Also, a light indicating issues with the traction control system comes on. ABS system seems to be failing or indicating failure almost constantly. Cruise control is disabled during these times. I've read this is a common problem with these vehicles. There really needs to be a recall issued for this. Is my truck safe to drive if the braking system functionality is in question? Not really.
My ABS / Electronic Stability control warning lights keep coming on intermittently and also sometimes staying on for hours at a time. I cannot use my cruise and my ABS will not work with these problems making this a very dangerous truck to drive. I have read that there are many other trucks with this issue. More specficially the 2017-2018 Ram 2500's. I believe there should be a recall for these parts as this is a intergral function in these HD trucks.
ABS and Traction Control warning lights on dash, go off and come back on. Truck was in cruise control with exhaust brake on and tow/haul mode engaged. ABS/Traction control light flashed on, truck dropped out of cruise control, exhaust brake came on car following the truck almost collided with my rear bumper. This is a dangerous situation, it is also affecting the cruise control. The dash board ABS and Traction control light cycle on and off, however this last few days they have been on more than they are off. This needs to be fixed at no charge by RAM trucks.
Faults for the ABS (anti-lock brake system) and EBS (electronic braking system) have been coming on intermittently for a couple months. Now the faults are permanently on indicating the ABS and EBS needs serviced. The fault code is c0020-01which indicates the known malfunction involving the anti lock brake system module and anti lock brake system control. While these faults are present the cruise control also doesn’t work. This is a well documented and known issue with certain model years Ram 2500 and 3500. My truck had approximately 57,000 miles when the faults began.
The contact owns a 2018 Ram 2500. The contact stated that the Service Brakes message was displayed and deactivated the cruise control and caused the stability and traction control systems to fail to operate as needed. The failure wase self-corrected; however, the failure recurred shortly afterwards. The failure persisted. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 78,000.
ABS and Tracton control
ABS failed, cruise control and traction control are inop as a result. The risk is loss of ABS when traveling, especially on wet or snow and ice covered roads. It has not been inspected by a mechanic. The failure light is on in the dash cluster and I have clearly lost traction control and cruise control. This began on July 31, 2023.
The abs pump and module are bad and there is no replacement parts available through ram. The truck only has 32k miles. They say the parts are on back order. The truck has no abs function nor does it have vehicle traction control. This should be a recall as it’s happening to thousands of trucks. This is a blatant safety violation. Yet the new trucks are still being built with these parts that are somehow not available.
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.
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.
The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds with the cruise control activated, the cruise control erroneously deactivated causing the speed to be reduced. During the failure, the ABS and traction control warning lights illuminated. The cause of the failure was not yet determined. The local dealer was contacted regarding the failure. The manufacturer was not yet contacted. The failure mileage was 101,000.
ABS / Traction Control turns on and off intermittently without warning when this happens the cruise control turns off creating sudden loss of speed control
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: $179.00 diagnosis fee; $411.70 Labor to remove and replace HCM; $262.00 HCU (Part # 68143491AA); 447.50 labor to remove and replace ABS Module; and $388.00 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.
