2018 RAM 3500 Forward Collision Avoidance Adaptive Cruise Control Problems

Slide off road while braking. Braking problem due to recall, Manufacturer Recall NumberC4B / NHTSA Recall Number24V-896. Recall was to be fix 1st quarter of 2025, Now 2026 still not repair solution.

I had the ABS recall repaired 3 years ago when Ram was refusing to acknowledge this as a defective product. I paid for this repair. Under the recall I'm elgiible for reimbursement but the company is refusing to reimburse me for the repair after I sent them an invoice showing proof of work and my payment. This can't stand. Please force them to issue a refund for the $100 I am owed.

Abs and electronic control system lights intermittently come on and off constantly and have been for 25,000 miles. When it started happening Chrysler knew what the problem was hcu and abs module is malfunctioning but unfortunately no parts were available and couldn’t tell me when they would be available. I’m just now putting in the complaint due to just learning about this site.

The ABS light intermittently comes on/off. It pops up while driving, but goes away. Sometimes it goes on/off several times on short drives. I need to know if this is going to lead to an all out failure of the braking system or something else. I confirmed with the dealer, where I purchased the truck, that it's a known issue and the part is on national backorder. Based on my research, this appears to be a common issue with Dodge Ram trucks built between 2017 and 2021. I need to know what my options are since I plan to purchase the needed part(s) at my expense since my family's safety is at risk.

ABS system - flashes on and off dash, ABS has been inspected by dealership. Dealership said, could replace ABS but it could very likely have the same issue due to part malfunction. This malfunction causes- no cruise control, no traction control, sounding and lighting up on dash constantly.

ABS/Service Electronic Brake Control and Cruise Control lights constantly flash and chime while driving. Have been told that replacements parts have been on back order for over a year now. Any help will be appreciated.

ABS, Cruise Control and Traction control warning lights constantly flash on dash informing me that they are disabled. Dealer is saying that Ram canceled their part order for the ABS module part number 68347098AC needed to do the repair with an estimated 1 year date before it is available. Truck is unsafe to drive due to ABS and traction control being inoperable and was warned I may be liable if I choose to drive it and an accident were to happen.

Faulty abs and hcu module. They are defective units and discontinued for purchase. I contacted local dealer and parts are on back order for 5 months.

2018 Ram 3500, ABS, Traction Control lights came on 18,000 miles. Issue also renders Cruise Control inoperable.

The ABS light and Traction control light keeps coming on and off very frequently. I am being told it is the Hydraulic control unit, as well as the abs module. This seems to be a huge safety issue that many people are running into.

Abs electronic brake light issue,brakes spongy and feels like it’s lost braking power.

The Hydraulic control unit has failed. It has been taken to a mechanic and diagnosed. The electronic part has been replaced per my warranty info and mechanic recommendation and it is still failed, meaning the main HCU is the issue. The cruise control will shut off automatically and the ABS and traction control do not work while in fault. While towing a trailer up an on ramp, the HCU went into fault causing the traction control to fail and the pick up lost traction and started sliding sideways...Luckily I was able to get it under control without crashing. This was all due to the HCU intermittent failure, causing the traction control to stop working. While this is faulted, the ABS also does not work.

My ABS light and Vehicle Stability Assist/Traction Control light came on. I now do not have the ability to use my cruise control. I believe the vehicle is unsafe.

Abs light and traction control light comes on and off all day long. Brakes will lock up if you’re using cruise control when the abs and traction control light come on. Both lights come on at the same time. The parts needed for this issue is on back order.

Abs light on repaired under warranty once now back on again truck only has 20000 miles but out of warranty light has been on for about 3 months dealer said no parts till 2024 dodge is changing the parts to fix this is what they are saying so they new original parts replaced with new but same parts was not fixing problem they should issue a recall it is totally their fault

The contact owns a 2018 Ram 3500.

On my 2018 RAM 3500 beginning on Memorial Day 2023, the instrument cluster began flashing with a loud door type chime. The cluster began cycling through messages including Service Electronic Braking System, ABS Failure, and illuminating alarms. Upon testing with a code reader I was presented with the following codes: C0020-01 ABS Pump Motor Control - General Electrical Failure and U0402-00 Implausible Data Received from TCM. Upon internet investigation, I discovered this is not an uncommon problem with several hundred reports available on ramforumz.com and other sites. According to several complainants, the repair for this will cost in excess of $2000 with one complainant stating this has had to be repaired twice as the replacement components are also faulty. This needs to be investigated and frankly needs to be a national recall on these vehicles, it is a lot more dangerous than a tailgate lock issue. I am concerned with...

The ABS/HCU module failed. I had to replace on 05/14/2021. At the time of replacement, I was unaware the NHTSA launched an investigation October of 2022.

No incident as of now but brakes are spongy and ABS TRACTION CONTROL LIGHT IS COMING ON AND OFF bad HCU ABS MODULE.

I was driving at highway speeds when the abs / traction control light came on. Notice cruise control was inoperative. The next day the warning lights were off. On the way home from work the system quit functioning again. After diagnosing found codes C0020-01 & U0403-00. ABS control module failure. I was told by the dealer this safety issue was not covered under warranty.

The ABS Anti lock lights came on and says check Electrical Brake System. Dealer said The ABS anti lock brake pump assembly was bad and it was on me to replace it. This is a big safety Issue to me. I got a 2018 3500 ram and paying big money for a truck and my safety, there should be a recall before some people get kill.
