2018 Ram 2500 brakes complaints
Page 66 of 79: complaints 1,931 to 1,960 of 2,349, newest first, as owners wrote them.
The vehicle experiences intermittent fault displays for "electronic brake service" and "ABS Service". This causes the vehicle to suddenly come out of cruise control and slow dramatically. This causes the vehicles ABS safety function to be inoperative reducing the overall braking capability and increasing the safe stopping distance This causes traction and stability controls to be disabled further degrading the built in safety features This was diagnosed several months ago by the dealership as an ABS hydraulic pump problem with no parts availability. The lack of parts has been an issue for months and has rendered my vehicle inoperative. The dealer said this was a common problem and that they had multiple Ram trucks with the same problem. I also checked online and found multiple reports of the same issue across the brand and across the country. This is a significant and costly repair >$800 for a part which is clearly underdesigned for the applicaiton with poor or little reliability.
At random times I get a chime and dash lights that say service antilock break system and service electrical breaking system. It wont happen for a week and the suddenly it will chime and flash every 10 seconds until the truck sits over night. I have replaced all abs sensors with no change. I’ve taken it to the dealership 2 times and they wont even look at it because it doesn’t show a code. I’ve read countless people online complaining about this same issue and some who have even had break failures. It’s amazing this isn’t a recall item with the number of complaints and lawsuits I’ve read. Hoping this will help get a recall started as the problem is potentially dangerous and incredibly annoying to deal with. It also shuts the cruise control off.
No accident YET. My Service ABS light and Service Electronic Brake light have been coming on and off for the past 3 to 4 months. I took my 2018 Ram 2500, (odometer 44,000 miles), to the dealer and they ran a diagnostic and found, ABS Pump Motor Control circuit and ABS Control Module failure. The informed me that they could not order the required parts because they are on national backorder. They also informed me that if I was in an emergency braking situation my ABS could fail and not activate. I had a couple of conversations with Ram corporate and they didn't seem all that interested or concerned about my situation. it is my understanding that the parts, required to fix and eliminate this potentially hazardous safety issue, could take six to nine months before they are available. I don't know what to do. Drive my truck, my only means of transportation, and hope for the best for myself and other motorist's and pedestrians? Or don't drive my truck and not be able to go to doctor appointments, grocery stores etc. I almost forgot to mention that Ram did offer to pay for 1 month car rental. What good is 1 month going to do me when it could take 9 months before the parts required is even available? In my opinion, Ram should pick up the tab for a rental vehicle until this problem has been resolved and pay for the required repairs.
ABS and Traction control warning lights and chime are constantly on-off, on- off. Took vehicle to dealer, diagnosed as brake module. The module was Replaced. The Same condition persists within 20 miles of repair. On return visit to dealer, brakes were diagnosed as brake pump failure. Dealer says the pump is back-ordered for several months latest ETA Aug 2023 for "engineering review." The dealer says the Anti-Lock system "should" default to standard style braking without any anti-skid or anti-spin. The truck seems to drive normally except under very heavy braking where the brakes seem to over-engage without additional pedal pressure. I have seen multiple claims for this same failure on the same model truck. The dealer did not specifically state the vehicle is unsafe. However, the dealer cannot issue a NH State safety inspection for the vehicle while the ABS light is on. This renders the vehicle unusable until the parts are released and available.
I have been experiencing issues with the ABS/hcu units. The warning comes on every bump and the ABS says it is not working I had it serviced last week 4/18/2023 and diagnosed as the ABS/hcu needs replaced and was ordered. Unfortunatley this is on bo until 8/16/2023. I undertand the 2019's had a recall but my 2018 does not?
Check brakes light comes on and covers digital speedometer. Dealership doesn’t know when they can get pump to fix??? Am I to drive this truck with faulty brakes until them?
ABS hydraulic control unit has went out with 6000 miles. It’s a known issue to ram back order of part is 6 months. There are lawsuits over this issue. Why can’t we have ram fix this safety issue. Does it take people getting killed to make this a recall?
The contact owns a 2018 Ram 2500. The contact stated that the ABS warning light had illuminated on the instrument panel. The vehicle was taken to a dealer and the contact was informed that the ABS module needed to be replaced. The vehicle continued to experience the failure after the repair. The vehicle was taken back to the local dealer and the hydraulic control unit module was replaced; however, the failure persisted. The contact was then informed that the ABS control module needed to be replaced again. The manufacturer was notified of the failure and a complaint was filed. The vehicle was not repaired. The failure mileage was approximately 17,000.
HCU is bad, per dealership. Can NOT order part because of backorder on said part. Light will go on and off.
The abs and traction control keep coming on and off. Sometimes the truck will sink the Brake. This is a very common problem that happens on these trucks. This is my second time that it goes out on my truck. First time went out at 40k miles now just went out on 76k miles. They’re needs to be a recall set on this as it’s so common to go out on such a short period of time!
ABS warning light on dash. Took to dealer, confirmed pump defective. Service manager said part back ordered until August 15, 2023. No recall listed. Vehicle is RAM 2500, milage 11,500 approximately, 2018 model. Other components on truck will not operate as well.
Electronic Braking system continues to fail. No ABS or traction control when towing trailer or RV.
Abs control Module & hcu failure Below will not let me updat date problem started approximately a year ago.
ABS light has been intermittently going on and off over the last year. 67,000 miles and it’s not covered under warranty. Dealership is staying I need an entire new module = $1,900
The contact owns a 2018 Ram 2500. The contact stated while starting the vehicle, the ABS and the service electric braking system warning lights illuminated. The vehicle was taken to the dealer and the dealer stated that the ABS hydraulic control unit needed to be replaced. The vehicle was repaired. The manufacturer was contacted, and a case was filed. The failure mileage 36,600.
ABS and electronic brake control warning lights come on intermittently. Dealer diagnosed ABS Hydraulic Control Unit is bad. Code C0020. Truck only has 44,900 miles. Unsafe towing which is what these trucks do.
ABS and HCU are in need of replacement parts. Because no replacement parts are available, I have no choice but to drive a Truck with questionable Breaking System, putting me, my family and others at risk, since the brake system is what stops my Truck when I need it to stop or slow down. I use this to tow the family travel trailer as well. This is also very important when brakes are needed to function safely. I have taken the Truck to my dealer of purchase. They completed a diagnostic test and also reproduced and confirmed the problem. The vehicle has been inspected by the manufacturer's dealership Service Dept. The Truck's "ABS SERVICE BRAKE SYSTEM" warning lights and warning tones alerted me of service needed back in November 2022, with just over 36,000 miles. I made an appointment and the dealership serviced my truck in January 2023. Since no parts are available for the repair, I had no option but to pay a diagnostic's fee to have my vehicle released to me, still in need of repairs. The warning lights and signals continue to go off repeatedly whenever I drive my Truck, letting me know that there is a SAFETY ISSUE THAT NEEDS TO BE FIXED!
Hello, my ABS system on the vehicle has failed with only 27,000 miles on this vehicle. Error code C0020-01 Warning system sounds every 5 seconds. It’s very distracting while driving and dealer ship for repair is 2 and a half hours away. No way to disable alarm.
abs brake failure
ABS, TRACTION CONTROL, REPAIR ELECTRONIC BRAKE ALERTS HAVE BEEN FLASHING WITH AUDIBLE BEEPING AND AT TIMES REMAINS LIT WITHOUT BEEPING. Putting a load on the engine or hitting bumps on road seems to cause the warning lights and beeping. This has been going on since June of 2022. Vehicle was taken to shop and diagnosed with failing part (electronic abs brake module) Part was not readily available and waited two months for part for repair. Cost $525.00 total. Did not fix problem now repair shop states the truck needs HCU hydraulic brake fluid pump. Its been EIGHT MONTHS no part available. Truck is in need of repair, no parts available and has limited our use of airstream tow vehicle for travel.
ABS Module and Service electronic braking system lights come on approx every 3 -5 seconds or stays on continuously. Which results in poor and dangerous breaking performance. Have been told it’s the ABS module and hydraulic servo. Dealer unable to obtain parts from Chrysler.
The antilock braking system warning is on randomly and I have already replaced the electronic portion of this unit. I spent almost $1100. Now I am being told the hydraulic portion is bad and is unavailable because it has been sent back for redesign.
Warning lights for "Service Electronic Braking System" and "Service Antilock Brake System" appeared sporadically for 3 days, then remained lit continuously. RAM dealer service advisor said it's diagnosed as a failure of the Hydraulic Control Unit. They also advised that the part is on back order and not expected to be available until August 2023, that the truck should not be driven and that I could try contacting Chrysler for more definitive information. I did contact Chrysler, who assigned a "case number" for future reference and invited me to call back in a week if I had not heard from a case manager. I noted that this is an issue of interest to NTSB and am reporting in hopes that you can apply pressure for remuneration for the loss of use and expedite resolution. Chrysler is not much affected but my family is without an essential vehicle and faces significant expense to accomodate this "known defect."
The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed with the cruise control activated, the electronic brakes and ABS warning lights illuminated, causing the cruise control to deactivate. The vehicle was taken to the dealer, where it was diagnosed that the ABS module needed to be replaced; however, the replacement part was on backorder. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 22,877.
The hydraulic control box has been bad in my 2018 Ram 2500 since October of 2022. I have tried to order the part through two different dealerships and three times now directly from Mopar, where my order was cancelled. We were originally told the part would be available in December, then March, now it’s August. The ABS and traction control warning lights ding on and off constantly, which is obviously annoying, but much worse- this is our family travel vehicle. We travel with two children and are frequently hauling heavy loads- a large trailer full horses or a 10,000 lb boat. Not having antilock brakes period is a danger, but hauling heavy loads puts us and the vehicles around us at risk.
The contact owns a 2018 Ram 2500. The contact stated that the ABS warning light was illuminated. The contact took the vehicle to the dealer and the ABS module was replaced. The contact stated that the failure persisted. Additionally, the vehicle was leaking fluid from the rear differential. The ABS module was replaced 3 times. The vehicle had not been repaired for the oil leaking from the rear axle. The manufacturer was made aware of the failure and opened a case regarding the failure. The approximate failure mileage was 11,000.
