2017 RAM 2500 Electrical System Problems

C4B 2017 Ram D2 DD DF DJ DP Hydraulic C / Not Available We are at Risk everyday Yes Confirmed Recall and Problem Yes inspected by Ram Dealer & CarMax The warning lights and the noise constantly goes off and they’ve been happening since a few days after we purchased the vehicle and the dealership that we purchased, the vehicle knew about the problem and never fixed it until this recall which they’re still not fixing for us. I am going to file a lemon lawsuit. Unless they solve this issue. $40,000 Vehicles should not have these issues. The brakes are locking up and almost crashed several times . I can forward the receipt from the dealership, but it’s not letting me upload it on this page.

My truck will lose all throttle response and brakes harder to stop accompanied by a service electronic brake system, service electronic throttle control, and electronic traction control warning. It only happens intermittently and sometimes will go a few weeks before doing it again. (The date below for incident is latest date it happened)

The contact owns a 2017 Ram 2500. The contact stated that while driving at an undisclosed speed and attempting to activate the cruise control, the system initially failed to engage. After several attempts, the contact was able to activate the cruise control; however, while attempting to deactivate cruise control, the system failed to disengage. After several attempts the cruise control disengaged. There was no warning light illuminated. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed or repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 18V332000 (Electrical System, Speed Control); but the VIN was not included in the recall. The manufacturer was not notified of the failure. The failure mileage was 178,000.

This is related to recall C4B/NHTSA 24V-896. The ABS/ESC/Traction control warning lamps come off and on while driving. The recall states that this issue may cause a vehicle to crash without prior warning.

Illuminated warning lights: The ABS warning light, as well as service messages for the electronic brake control and anti-lock braking system, will turn And off. Check engine light will come on and off. Dinging sound and message on the screen: A persistent, intermittent dinging sound may accompany a flashing message on the instrument cluster indicating a system problem.

Continuous warnings and tones showing issues for anti lock brakes and stability traction control. In less than 3 months will be a year since the recall was announced and there is no remedy. This is a nuisance and safety issue and should absolutely be a priority to fix. NHTSA #24V-896

This is my 2nd NHTSA complaint regarding this issue on my 2017 Ram 2500. Initial online complaint was done on 4/30/2022 regarding the trucks annoying and unsafe warning light indicating “Service Electronic Braking System” and amber ABS warning light. These warnings began on my truck in 2021 when it only had 12,000 miles. These intermittent warning lights and audible “dinging” still persist today at 22,000 miles. On 2/8/2025, I received notification of Recall #C4B (finally) as a result of the class action lawsuit and was pleased to see this development. To date, I, like many Ram owners are still awaiting parts to become available to have them replaced per the recall and am requesting that the NHTSA step in to assist as we all have essentially unsafe trucks on US highways. I believe this should be a priority, given the fact that owners of 1500, 2500 and 3500 trucks often...

The check engine light came on and I took the vehicle to the Ram service center. The tech said the turbo actuator caused the light to go on. He reset the computer and said to bring the vehicle back if it comes on again. About 1 month later it reappeared. The Ram service said the turbo charger actuator needed replacing (the complete turbocharger). They said the failure could result in a total loss of power or engine failure. I tow a 10,000 lb trailer and an engine failure on the road could result in an accident or injury due to no power from the engine. The part can be viewed for inspection.

The contact owns a 2017 Ram 2500. The contact stated that while driving at highway speeds, the check engine, traction, and ABS warning lights illuminated. Once the warning lights had appeared, the speedometer, odometer, and cruise control functions failed to operate as needed. The contact also stated that the transmission failed to shift out park(P). The vehicle was taken to an independent mechanic, where a code reader determined that the failure was linked to the ABS control module. The contact then received notification of NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The local dealer was made aware of the issue and confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue, and the contact was provided...

Grid Heater bolt failure. Grid heater bolt is secured by a nut below intake area. The nut on bolt melts and causes pieces and shards into cylinder #6 if not fixed immediately. This is a terrible design and expensive fix. I am 3rd person to have this problem recently amongst my friends. Metal in side motors should not be melting and or rotting into cylinders. Please see attached pictures showing melted bolt and shards in the intake area. If this is a part that needs maintenance it should be listed in the scheduled maintenance somewhere

ABS/ELECTRIC BRAKING SYSTEM LIGHT... HAD ABS PUMP MOTOR and HCU REPLACED 2 TIMES WITHIN 28 MONTHS AT MY COSTS..LESS THAN 60K ON ODOMETER

Issue a recall here! Many others are reporting this identical issue and a class action suit has been filed! ABS sensor light and chime comes on at random times. My truck just reached 100,000 miles. I've performed no troubleshooting but it is extremely intermittent, either the Service the Automatic or Service the Electronic Braking System(s). Usually, a bump in the road makes it come and another turns it off. Sometimes it happens so quickly, only the message and traction control disabled light comes on, sometimes only the chime comes in. Sometimes the message stays up and the brake warning and traction control light comes on, sometimes for a few minutes, sometimes a couple of seconds. To compound the problem, there appears to be an issue in sourcing replacement parts resulting in a delay in repair. A delay in repair could result in a additional damage to the vehicle, not using...

The illumination of the ABS light and traction control light. The light actives intermittently. The reported problem from a vehicle code reader is “ ABS pump motor control general electrical failure”. With the lights illuminated, I am no longer able to use cruise control. Prior to the warning lights I noticed I was having to depress my brake pedal harder than normally at random times. No signs of brake fluid loss or leaks. The brake pads are in good working condition. I have not taken it to a dealer as I have read the replacement parts are on back order and there are multiple lawsuits pertaining to this issue as well.

Abs light goes on and off intermittently. Caused my truck wheels to lock up in fast stop maneuver. Dealer said ABS module needs to be replaced but there is no recall yet.

ABS and Traction control warning lights are on display. Cruise control and 4x4 will not engage due to this issue. Also causing malfunction while towing a trailer.

ABS / TRACTION CONTROL AS WELL AS SERVICE ABS SYSTEM. AT TIMES IT COMES AND GOES AND MOST TIMES NOW IT STAYS ON. DISABLES CRUISE CONTROL AND AT TIMES EVEN SAYS 4 WHEEL DRIVE UNAVAILABLE. THIS SEEMS TO BE A KNOWN ISSUE WITH MY YEAR MODEL RAM AND I'D LIKE TO REMEDY THIS ISSUE ASAP.

2017 Ram 2500 crew cab ABS light on know traction control light on will not engage in 4x4 because ABS light on Code said ABS C0020-01 ding,ding,ding,ding always.

ABS and traction control light flashing randomly. Causing cruise control to shut off randomly. Caused by faulty ABS modal, and or HCU. This is a know major issue with 2017 rams with parts not even currently available to fix.

Truck has had two ABS units replaced under warranty for the code C0020-01. Now a year after the last replacement the code has come back and needs the ABS unit replaced again. FCA knows there is an issue with these and continue to sell and install parts that they know will fail. This will cause the loss of ABS braking, traction control and trailer braking. Someone need to force FCA to provide a "correct" repair and ungraded parts for this error.

The vehicle has an intermittent ABS TCS warning that Dodge refuses to recall and fix. The warning light goes off incessantly it should be a recall and Dodge has known about the problem for 7 years at a minimum.

Service ABS Electronic Braking System Message, ABS as well as Traction Control light intermittently coming on and shutting off, Sometimes staying illuminated awhile then going back to coming on Intermittently. Took to shop and ran diagnostic trouble codes on truck. The trouble codes saying ABS/HCU Pump Module Electrical Failure. Recommended fix is to replace ABS Pump Module. I am aware of the class action lawsuit and this same issue on most all 2017-2018 Ram 2500 trucks. The problem I am presented with now is, The ABS Pump Module is on national back order which is making it extremely difficult to find a replacement. I am now left with a truck that is unsafe to drive as a father and husband due to the vehicles Antilocking Brake System not functioning at all as well as the Traction Control System not functioning at all. Due to these issues when I am forced...

2017 Ram 2500 ABS Pump Module was replaced before at 33,549 miles in May 2021 ABS and TCS Lights keep coming on now again at less than 49,000 miles. This is not an uncommon problem it seems, so I am adding my incident.

At approximately 101,000 miles, the service Electronic Braking system and service Antilock Braking system warnings began showing up intermittently on the dash. I have taken the vehicle to a dealership and have been quoted between $1,500 and $3,000 for repairs once parts are available, with a 6 month wait for parts. I was notified that parts had become unavailable in the second half of 2023. I have lost cruise control and slight braking performance due to this on top of the nonstop annoying dinging going on.

At around 80k miles, started getting the service anti-lock brake system, electronic braking system alarms. Traction control light and abs light are on permanently now. What's funny is that now the rear parking sensor failed which makes me wonder if all this in the electrical system is tied together. Dealer said it was the hydraulic control unit. That did not fix it. Next it was a wheel speed sensor. That did not fix it. Then it was abs module but it is "discontinued." In other words, Chrysler knows there is a major issue and NEEDS to issue a recall but hasn't yet! I have over a grand in this and it's not fixed. Dealer said that they don't know what the fix is. Please issue a recall!

•abs pump motor control general electrical failure •no abs or traction control •yes has been confirmed on a professional scanner •no •no lights until it went bad again Replaced the and/hcu in October of 2020 due to the dtc c0020-01 and all was fixed until June of 2024 and now the same code is back. Not wanting to replace the same part again just for it to go bad in 2 years.

Intermittent MIL stating ABS and TCS service required, started has been going on since I bought the truck in January 2023 at about 50k miles (currently about 75k). Often happens when driving over any sort of uneven terrain - bumps, potholes, seams between concrete and asphalt surfaces, milled asphalt surfaces, speed bumps, debris, etc. Dealer says the ABS module needs to be replaced, and that there are none available. With some research, this appears to be a common/known issue for Ram trucks, but no recall and no effort to even manufacture the part so it can be fixed, regardless who is stuck with the bill. When this light comes on, neither 4WD nor cruise control function, which can cause safety concerns - especially while towing.

Abs module and pump goes on and off about to put the third one on the truck and only has 74,000 miles

ABS module constantly going off and removes 4 wheel drive, parking assist, traction control, and and brakes

ABS module unit replaced while under warranty. Vehicle again with ABS warning on/off intermittently for at least the last several months...regardless of weather, speed, road conditions, etc. Comes on and off while driving, sitting in a parking lot...pretty much as soon as I turn on the motor it starts...goes off again for several minutes/hours/days, then starts doing the blinking and dinging again for no reason. While traveling, it turns off cruise control and I have lost 4 wheel drive when I've desperately needed it. This vehicle is only used for long distance travel or during snow storms. This is a safety issue, in my opinion. Causes operational malfunction and causes driver distraction.

ABS and traction control lights intermittently go on and off. Most of the time just by driving over a bump. Constantly going on and off. Many forums online about this related issue. Many talk about pump being replaced and not solving or the Hydraulic Control Module replaced and not solving and many talk about faulty electrical connections. Error code: C0020-01 ABS Pump Motor Control - General Electrical Failure

On my truck my ABS and traction control light came on as well as a message that say to service ABS system. The parts are on back order for a year now. This problem has surfaced on many Ram 2500's. I contacted the dealer and they don't have parts to fix if. When driving in wet conditions especially while towing a trailer the wheels lock up while breaking. I've been towing going down hill and have had to use a combination of engine breaking, downshifting and feathering the brakes to slow down. Chrysler Fiat should issue a recall on this issue since it happens to many Ram 2500. This started when I had only 38k miles on my truck. Chrysler fiat has issued a recall for the 2019+ trucks but not the 2014-2018 which have the same exact problem. I'm hoping you can help this matter.

Brake error and traction control error on dash. It is available for inspection. Not sure if it is safe but we have not options. This started several years ago. We have looked at ordering parts and tried to make appointment at dealer but parts were out of stock. We have not ever taken it in to the dealer as this happened literally 2 weeks after our warranty expired. No one has inspected it. There were not any other warnings prior and the vehicle seems to function but it is annoying driving it as the warning goes off all the time. I know they recently recalled newer Dodge Rams for this same type of issue but seem to be refusing to recall the older models for those of us that have been waiting and hoping nothing safety wise happens. It is a well knows issue and there are class action suits...

Continue to get Service ABS and Service Electronic Braking System warning lights. ABS does not work when warning lights are on returns to normal when warning is off. no other detected issues with the braking system. It is displaying code: C0020-01

For the second time, my truck is repeatedly having "Service electronic braking system" message appear and disappear constantly while driving. This is mixed with "Service ABS system" message that also repeatedly pops up with a audible ding. The warning lights for traction control and ABS repeatedly turn on and off as well. This happens over and over the entire time while driving. We were on a family trip with our 1 year old when this started again most recently. We had to turn back around, drive home and swap trucks and everything in them as we can not have potential brake failure with our 1 year old in the vehicle. The trucks has just over 51,000 miles and this is the second time this has happened. The first time the truck was under warranty, so it was "fixed" by the dealer. I am no longer under warranty. The part to...

We too our 2017 Dodge Ram 2500 to Lenoir City Chrysler Dodge on January 11, 2024 because the Antilock Brake System (ABS) and Traction Control warning lights were coming on. The truck was in the shop for about a week. We were told initially that the part (electronic control module) was on order. Then we were told that the part was under redevelopment and that they did not have a date for when the part would be available. We do not know if the truck is safe to drive or not so we have not been driving it. All we want is to purchase the part so we can use a truck the cost us $43,000.

Traction control and ABS lights flicker on dash cluster. Possible ABS module failure. Parts on back order, I believe this is a safety hazard that needs to be corrected by a recall. This is a known issue that has yet to be resolved since 2017. That's unacceptable.

Service Antilock Brake System & Service Electronic Brake System on 2017 Ram 6.4 hemi

The contact owns a 2017 Ram 2500. The contact stated that the Service Electronic Braking System warning message had appeared on the instrument panel. As a result, both the remote electrical start and the cruise control features failed to operate as needed. The dealer acknowledged the failure but informed the contact that the part needed to repair the failure was unavailable. Once the part became available, the contact was given an estimate for the repair. The manufacturer was also notified of the failure and agreed to cover for part of the repair; however, once the part became available, the manufacturer no longer offered any financial assistance. The vehicle had yet to be repaired. The failure mileage was approximately 52,000.

Abs pump failure on a vehicle with 80k miles.

The ABS and Traction control lights began to flash and the alarm began to come on intermittently in 2021. I took the truck to the dealer for repairs because the ABS, Traction Control and Cruise Control were not working. The repair cost was $1,00.00 at my expense. The problem has recently returned and is going to need repaired at my expense again. The ABS system not working causes a safety concern with stopping the vehicle. This is a know issue with these vehicles as such I feel it should be the manufactures responsibility for repairs.

My truck has a failure of the ABS system to include the cruise control. This failure has resulted in the brakes locking during slick conditions and the vehicle to slide. I was not going fast so there was not crash. My truck is showing a code coc0020-10 (ABS pumpmotor control-general failure). This failure was repaired (replaced the HCU) by the dealership on 10/06/2020 and this temporarily fixed this issue. In 2022 this issue started again, and I contacted the dealership and was referred to Ram customer support. Ram customer support told me that the HCU was under engineering review and the review should be completed by Aug 2023. At last check there has been no new part number to replace the defective parts. I feel this issue should be fixed with a mandatory recall.

ABS, electronic stability control and speed control not working. Code C0020-01 ABS Pump Motor Control.

ABS and traction control light. Continue to flash on and off cruise control will not work when light is on and traction control does not work. One light is on. I Heard there is a class action lawsuit in California trying to have my vehicle fixed. It continues to beep whenever I hit a bump or take a turn. Sometimes it's on. Sometimes it's off

ABS and traction control light came on, when faults were pulled, active fault # C0020-01. After contacting dealer, Service department stated it is due to faulty ABS module and Hydraulic control unit in 2017 and 2018 models. Parts are on national back order with no available ETA.

Picked up my truck from the dealership and my ABS, and traction control light came on, and i lost my abs function and traction control. The my dash started flickering and it would go in and out. Now my heat also has stopped working. Truck is saying service abs system, service electronic braking, service rear park sensor. I do not feel safe in this vehicle as i did my research and see how many vehicles have been affected, i cannot believe Ram has not done a recall as with out my abs i almost slid off the road as it was icy out that day and i was unaware my abs would just stop like that.

ABS, Electronic control system malfunction. Constantly failing causing safety to driving.

Vehicle has about 60,000 miles. Has started intermittent service electronic brake and service abs warning. Noticed alot of information online that this is happening more than a normal rate of failure. I believe where this is being looked into...hoping for a speedy response. Thank You!

A Hydraulic Control Unit malfunction resulting in multiple warning lamps flashing on and off intermittently - including the ABS, the EBS, the Traction Control, and the Cruise Control. This is apparently a known issue with this model year truck and is inclusive of a class action lawsuit, yet there has been no recall. This failure results in unpredictable breaking and/or the ability to break and operate, especially in slippery conditions. This replacement repair is estimated at $1,100-1,300 on top of incredible uneasiness to operate the vehicle.

Digital instrument cluster has stopped working.

Anti-lock break system malfunctioning. This module has already been replaced once in 2021 by a dealership. Now the module is malfunctioning again and needs to be replaced. This affects the trucks traction control system and cruise control. Meaning the vehicle will slide during winter/rainy weather. There are to warning lights that come on on the dash warning you that this system is malfunctioning.
