Code for right rear wheel speed sensor came on. Resulting in no abs,traction control, 4x4,or parking sensors. I bought new part from dealer had mechanic change it. Reflash abs and still on. Went off briefly for 5 seconds came back on. I've realized it's it's common problem. Resulting in the abs module needing replaced. But it's only a temporary fix.
2018 Ram 2500 electrical complaints
Page 15 of 17: complaints 401 to 430 of 476, newest first, as owners wrote them.
ABS and stability control fails and warning lights activate intermittently 11/11/22 (47,290 miles) The cruise control disengaged without notice when the faulty modules light up. Under a heavy load this caused severe speed reduction and momentary loss of vehicle control Reported to dealer.(Rothrock motor sales) It is a know issue with thousands of suspect ram 2500's Parts are not available due to demand. This is an intermittent fault with the Stability control and/or hydraulic control module. Both parts or one part faults the other creating a hazard for all drivers Dealer was made aware of issue and states parts are back ordered months out if at all available causing customers to drive the trucks with unsafe braking due to no other means of transportation This is a well know defect being ignored by Chrysler/Ram
At 67k mileage my 2018 Ram 2500 abs, traction control and electronic braking system warning lights flash intermittently, dealer, auto parts store and several online sites state it is the ABS and HCU modules electrical failure. This causes the abs system to malfunction and poses immediate threat for crash especially while pulling trailers. When the lights flash the cruise control will no engage/disengage. No dealer has these module with no clear indication of availability as of 1/27/2023
Abs on off messing with cruise control. In snow conditions feel it’s a concern. Sometimes the abs work’s most of the time it’s on/off multiple times while driving. For a 2018 truck with only a little over 24,000 miles not happy that at this time the dealership says they have no clue when they will have parts to fix
The infotainment screen is malfunctioning. It makes phantom button presses. The most dangerous of all is when I am backing up. Instead of it showing the back-up camera it shows the bed camera. Very dangerous!!!!
I have made a previous report about this vehicle. New things are happening now. My mirrors are tilting and changing while driving. The backup camera is still coming on in while driving down the highway. I can't keep the heated wheel turned off. It gets so hot, its hard to hold the steering wheel. I have to pull off the road and turn the truck off. I cannot use my Bluetooth while driving because it starts calling random people, then it starts reading all my text messages. Its against the law to hold your phone while driving in NC. The doors lock and unlock while driving. I bought this truck a little over a year ago and this ghost in my truck is driving me crazy. It's unsafe while driving, with the mirrors tilting. I change the settings and the ghost changes it all... please help.
- I have a repeated low mileage failure of the antilock brake system hydraulic control unit. The faulty unit is still installed on the vehicle. - The ABS hydraulic unit failure intermittently renders the ABS system, traction control system, and electronic stability system inoperable for varying durations. This is the 2nd failure of this system on the vehicle. The first failure occurred during normal highway driving. The 2nd failure occurred while traveling in the mountains in the snow. Had I not been experienced driving a non-abs vehicle in inclement weather we could have crashed. - The issue was diagnosed and confirmed by a local Ram dealership service department. It was escalated to Ram customer care due to lack of parts availability and high cost of repair. Ram escalated part delivery and denied financial assistance. The vehicle is out of warranty for this particular part. - There are various intermittent warnings present. The fault condition will rapidly annunciate and then clear many times in a short time period, or stay active for long periods, or not occur at all. The fault condition appears to be completely unpredictable but is repeatable.
Anytime while driving the truck waring lights on the dashboard will come on intermittently. The ABS and traction control light will come on, and on the display screen two different messages will appear along with alarm sound constantly dinging. One message says (Service Electronic Braking System) the other says (Service Antilock Brake System). If driving with the cruise control on when those lights and messages appear the cruise will stop working. This problem is intermittent it comes and goes, but usually very often. The truck is out of warranty with 41000 miles on it and this has been happening since Sept. of 2022. I had it diagnosed by an independent garage and had two trouble codes (C0020-01 ABS Pump Motor Control General Electrical Failure) and (C0020-16 ABS Pump Motor Control Circuit Voltage Below Threshold). The truck still seems to stop normally, but I feel very unsafe driving it. The ABS Hydraulic Control unit is unavailable from the dealer. As of today Jan.-18 2023 they are saying it will not be available until March-15 2023. This is most definitely a safety issue on the truck which should be recalled. The dealer says the parts problem is a supplier issue. I believe the manufacturer knows these are defective and is trying to avoid recall.
The ABS module and associated control unit have failed. This causes the anti lock braking and traction control systems to be inoperable which can cause the vehicle to lose control which can cause injury or death. FCA is aware that these units are defective and refuses to fix them.
C0020-01 code began coming in and out immediatly following a service at my local Ram dealer. I returned to the dealer after the warning lamps and messages all came in around ten times within a mile of picking my truck up from them. The dealer used a device to clear the messages, but the alarms returned again after I left. There are multiple warning lamps and messages that remain in as a result of this: service anti-lock braking system, ABS warning lamp, traction control lamp, and a loss of cruise control functionality. While the constant "dinging" sound and loss of cruise control on a truck with less than 20K miles is disappointing, I am concerned whether or not these warnings are indication of a serious safety hazard to my family and/or those we are on the highway with. My truck is available for inspection. The issue was confirmed by my local dealer who cleared the alarms when they first came in.
Abs and traction control lights come on and off dealership replaced the hcu and the problem stopped. 2 years later and only 3,000 problem started again. Contacted the dealership and they said its a known issue but no parts are available and no recall
Traction Control Light is illuminated, Service Trailer Braking System, and Service Trailer Brake System Notifications are present on engine startup. ABS system appears to be inoperative in slippery conditions. Service Engine Light comes on every 15 miles or so with Codes P0572 and P0572pd. Download codes and they go away.
Multiple failures on ABS Brake control module. Module has failed twice now within 30,000 miles. Manufacturer has no urgency in prdocing replacement parts. Cannot drive vehicle due to this issue.
ABS and Traction Control warning lights flash on and off constantly and there is a warning tone that beeps non-stop on my 2018 Ram 2500. When these warnings appear, the ABS System and the Traction Control are disabled along with the cruise control. This has happened twice already, and my truck only has 4000 miles on it. The first time was in October 2021 when the truck had under 3000 miles on it. The dealership replaced the ABS pump which fixed the problem temporarily. In August 2022 the same problem appeared, and the same warning lights came on. At this time the truck had around 4000 miles on it. I took the truck in for service in October 2022 and even though the truck was out of warranty, I still had an extended warranty contract. This time I was told it was the ABS Control Module and that the part was on backorder for 3 months or more and that since they could not get the part I was not covered by the extended warranty and was charged a $175.00 diagnostic fee, but that if they were able to get the part that I would have been covered by the warranty. All the dealership was able to do was reset the code which lasted for about 20 minutes before the problem started again. It is now December 28, 2022, and I have had to drive around for the last 6 months with the dashboard flashing and the truck constantly beeping and with the ABS, Traction Control and Cruise Control disabled. I have seen hundreds of complaints regarding the same problem and yet Dodge has not issued a recall regarding this issue. It's beyond comprehension that my truck has had the same problem twice and it only has 4000 miles on it and now Dodge is telling everybody that the part is not available until next year, and so everybody that has this same problem has to drive their truck around with flashing warning lights on the dashboard and a constant dinging tone which gets very distracting and annoying, and on top of that their ABS and Traction Control is disabled. This was my first and last Dodge.
Sporadic light warnings displayed on dashboard along with warnings of Traction control and Service ABS control module. C0020-01 code pulled with code reader. Dealership diagnosed that ABS Pump motor control failure and replacement was needed. Parts on recall until earliest Jan 2023.
In July 2022, the esc/abs dash lights as well as the ‘service electronic brake/service ABS’ warning began intermittently flashing with resultant loss of traction control and ABS including cruise control. It would continue to activate/deactivate numerous times over the next couple of months. The dealer has identified the hydraulic control module as defective requiring complete replacement of the HCU and ABS system. Online search shows this to be a common known problem along with well over 100 complaints filed with the federal safety agency regarding model years 2017-2018. Interestingly, there is a recall for this very problem for the same truck series years 2019-2022 for the same part. There are over 2500 orders for this part and my dealer is not allowed to place an order until mid February because of the backlog endangering my life to use my only vehicle that can be used in the snow this winter. Dodge is clearly not supporting its customer base with providing a known defective part replacement in a reasonable time frame forcing those that don’t have an alternative vehicle to risk their lives and those on the road around them by driving a 7000 pound vehicle that can lose control and not be able to stop given that we are now in the middle of winter.
In February of 2022 the radio console screen looked odd. It was very subtle and we weren’t sure what if anything we were seeing. The function was normal at that time. At this time the vehicle was under warranty and had less than 28,000 miles. It was having an intermittent check engine light in July and was due for service so we took it to the dealer. I told them about the console screen appearance and they said it was delaminating which they were seeing in these trucks. They did not say it was a recall issue. Since the replacement unit was over $1,000 and appeared to function otherwise we opted not to change it. In December the screen began to flash and act strangely. When we tried to start it the next day to take to the dealer, it had no power. We had it towed to the dealer The service advisor told us to speak to Chrysler RAM customer service as this was an unexpected failure in a vehicle with less than 30,000 miles. Our concern is the console unit is being replaced but with what. Has the flaw in the unit been identified and the replacement parts modified to eliminate the problem? Is the replacement part going to have the same problem? If we lost electrical power while driving it could have catastrophic consequences.
The ABS light will go on and off the dash over and over. The truck is 134 miles out of warranty and the dealer said the parts are the ABS pump and electrical board went bad. They do not have the parts to fix then and it is not warrantied now. This is a well known problem and there is plenty of knowledge at the dealers of the issues. They knew what was wrong without even driving the truck. The pump going bad at 36, 239 miles on my truck should not happen. They already have an updated fix but will not admit they sold trucks with a faulty ABS design and should be fixing these trucks for free. My ABS no longer works and I have no cruise control or traction assist and I live in the snow belt of Ohio. I no longer feel safe driving my 4 daughters around in my truck I am still paying for, it is not comfortable knowing a massive company like Ram is doing nothing about it.
Lost braking power. Anti-Lock brakes quit working. Lost cruise control. Unable to use anti-lock brakes. Brakes locked when stopping. Flashing dash alarm saying service ABS/Electronic Braking System. All occurring without reason, just randomly. This puts my safety and the safety of others at risk as the brakes lock up when depressed at times as well as loss of braking power.
Was driving on expressway exit ramp trying to come to a stop and the brakes hesitated and then locked up, at the same time the traction control and abs light came on. Traction control and abs lights still come on months later and problems with breaking are still there. Took to local shop to get fixed and they told me abs module and hcu pump are bad. Parts are not available thru mopar or aftermarket.
ABS system malfunctioning, “service electronic braking system” and “service abs” messages flashing continuously while driving. Known issue among Ram. Was quoted $1000 to repair ABS module.
Service electronic brake system indicator came on while driving vehicle. Warning continued to go on and off numerous times randomly and still continues to do so. Took it to dealership to have problem addressed and service worker said this was his sixth 2018 Ram 2500/3500 in his dealership to have the HYDRAULIC CONTROL UNIT and ANTI LOCK BRAKE module to malfunction. FCA should have a recall on this, but as of now they don't. Parts are back ordered and won't be in for months. Dealership told me it's fine to drive as is but I'd rather not take my chances. Please address this. Thank you very much.
HCU failing. Blinks on display screen. Appears then disappears. When in cruise control and the HCU goes haywire, kicks cruise control off unexpectedly. When this occurs and the driver isn't expecting it, this causes panic because the vehicle rapidly slows down, nearly causing a vehicle collision if not prepared for it. I was almost rear ended due to this. Research on this failure would reveal this issue to be affecting 1000's of 2018 RAM trucks to have this problem. My local Dodge dealer advised I am approximately the 2500th person waiting on the part which is currently on BACKORDER. Have been a Police Officer for 15 years, safe driver and this nearly caused an accident on 695 Baltimore County, MD during heavy traffic.
A few weeks ago, the seat and steering wheel was so hot, I could hardley hold the steering wheel to drive. I immediately checked the controls for the heat, it was on and I turned off, it turns back on. I finally found a safe place to pull over and went to settings and made sure it was off. It automatically comes back on, then it wouldn't let me turn it off. Finally it switches to cool seats, then then fan is coming on wide open and I couldn't turn that off. I finally shut the truck down for a few minutes. Then restarted the truck, then the truck wouldn't go in drive, it was stuck in park. I kept working with the shifter and finally got it in drive. As soon as I pull back into traffic, the backup camera is on, the radio starts going crazy, going from station to station, I tried turning off the screen, it wouldn't turn off. Then all my phone contacts come up on the screen and then starts randomly calling people. I couldn't make it stop until I disconnected it from Bluetooth. I finally made it home and shut the truck off, and disconnected the battery hoping to reset the entire system. The next day, same stuff, but different stuff. Doors locking and unlocking. Also, had to take off Bluetooth again, because it starts talking and reading all my text messages. I love my truck, but it is driving me crazy, it's so distracting trying to keep it from doing all this crazy stuff. The steering wheel getting hot is crazy, I can't get nothing done sitting on the side of the road. Please help!!!
The truck ABS, traction control, and service electric brake lights and warnings have flashed and beeped on and off and on and off every few seconds. I took the truck to the dealer to be fixed under warranty. The dealer states it has a bad HCU and no longer has anti lock brakes however I can still drive the truck with all that distraction going on in the dash. The part is on back order and I won’t have my truck repaired until February (2.5 months) This same part was also replaced a a little over year ago under warranty along with Abs sensors and wire harnesses. I have 2 friends with the same year trucks who also had to have the same repair done. Upon looking up information on the internet it seems like this has been a on going issue on the 4th generation ram trucks 1500-3500 models from 2012-2018 I feel the safety of this could cause a car accident by the distraction of the dash going nuts and the possibility of a vehicle skid while not having anti lock brakes properly working. I would hate to drive it putting my life as well as others drivers and passengers lives in the line due to this safety issue ram is having. The issue happens randomly some times non stop while driving and sometimes I can drive 15 miles or so with nothing then it will start again. It first happened when I had approximately 50,000 miles on the truck and has done it again at 73,500 miles. When the lights are on it will not allow cruise control to work or 4x4 to engage. I have not noticed anything else not working properly.
The LCD touch control screen in the dashboard has been delaminating for several months and is now malfunctioning causing the screen to change turn on and of settings such as heated seats, heat and AC. The screen will not remain off at night due to this malfunction causing an unsafe and distracting bright light coming from the screen remaining on.
The contact owns a 2018 Ram 2500. The contact stated that after two weeks of not driving the vehicle, the vehicle failed to start up after several attempts. Several unknown warning lights were illuminated on the instrument panel. The contact jumpstarted the vehicle and made an appointment with the dealer. The vehicle was taken to the dealer who informed the contact that they could not duplicate the failure. However, the dealer replaced the battery. The contact stated that the failure persisted. The vehicle was taken back to the dealer on two other occasions; however, the dealer could not duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 19,000.
ABS and Traction Control warning light keeps intermittently coming on and then a message saying that the Electric Brake system needs serviced. This has happened to my 2018 RAM at 17,000 miles. Dealer replaced ABS module under warranty and problem was solved. Now I am at 35,000 miles and the problem is back. Same exact issue. This needs to be a recall item ASAP and this seems to be a VERY common problem with these trucks. This could be very dangerous as these trucks are made for towing heavy loads and losing your anti-lock braking capabilities could be catastrophic to you or anyone else on the road.
Electrical issue with the radio. It will change screen, turn the radio up and down. Turn and off. Makes SOS calls on its on. Turn the AC to hot in Arizona when it's already 100+ degrees out. All while driving.
The ABS system warning comes on when I hit a bump. The audible warning sounds as well. It happens multiple times during a trip, even a short trip. The cruise control is disabled when this as well. When this happens, the truck is harder to stop. It is a safety concern. There is a recall on 2019 trucks for the same issue. The 2018 trucks need this same recall.
