While towing 10,000 lb trailer vehicle displayed indicators that traction control and ABS were failing. I've taken vehicle to dealer 5 times since recall and it's now over 1 year and Chrysler failed to remedy recalled defective part 68143491AA. Chrysler complaint case no. 95672952 filed on 2/16/26. Chrysler HAS in fact produced the replacement part No. 68143491AB - supersedes failed part no. above. Local dealers have qty 9 of part locally in stock and sell to public for $500. After calling many parts dept sources, I learned dealers are lying and telling current owners no remedy available under recall so that Chrysler can prioritize replacing Ram trucks traded in to dealers so they can fix under recall and make those vehicles sellable by dealers as highest priority for parts. However, dealers are also willing to sell the new part to consumers at full msrp at parts counter + labor in service center. So they make eligible customers pay full price up front and fight to get reimbursed later after being out nearly $1000 to fix Chrysler's problem. I get that there may not be enough parts on hand for every recalled unit - yet. But there are enough now at dealers that when a truck comes in to dealer service center with proven HCU failure indicators (traction control and ABS warning lights) those customers should be given the recall part with labor as required of Chrysler. In my case, brake failure warning lights were documented 7 months ago at North Fort Worth Auto Nation dealer service center under invoice #187541. So, there is no excuse why I'm now being lied to and told they don't have new part 68143491AB when parts mgr told me himself they have 8 parts in stock at that dealership alone as of 2/16/26. the federal safety agency is allowing Chrysler to self-regulate on this without sufficient oversight. After a year plus since first recall notice there is NO excuse why current owners should be denied available parts to fix this known major safety issue.

Incident Description (ABS Module Failure) The ABS control module is failing intermittently. The vehicle is available for inspection upon request. The ABS warning light illuminates unpredictably, sometimes every few minutes to every few tens of minutes. When this occurs, ABS, cruise control, and trailer brake control are disabled, making the vehicle difficult and unsafe to operate, especially when towing or driving in traffic. This failure creates a safety risk due to loss of braking and stability-related systems. The issue is a known manufacturer defect with an established repair; however, the manufacturer states that replacement ABS modules are currently unavailable due to parts backorder, with no repair timeline provided. The issue has been acknowledged by the manufacturer and dealer. No inspection by police or insurance has occurred. Based on available information, my best assessment is an intermittent ABS module failure that renders the vehicle effectively unusable. I am requesting escalation and corrective action by the manufacturer.

The contact owns a 2018 Ram 3500. The contact stated that while driving at various speeds, a message indicating a brake failure was displayed, and that the vehicle needed to be serviced was displayed. The vehicle was taken to the dealer, where it was diagnosed that the HCU had failed and needed to be replaced. The vehicle was repaired at the owner’s expense; however, the failure persisted. The contact later received notification of the federal safety agency Campaign Number: 24V896000 (Service Brakes, Hydraulic), which the contact related to the failure; however, the part to do the recall repair was not yet available. The local dealer was contacted. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was contacted for reimbursement but denied reimbursement because the contact did not have the original receipt of the repair that was previously performed on the vehicle. The contact provided a letter, and documents provided by the dealer, that confirmed that the repair was performed at the owner's expense. The failure mileage was approximately 14,000.

HI, My 2018 RAM 3500, had had a Anti-lock brake control module light on and off about a hundred times a day for the past year, I just spoke to the Ram Service manager at Leith Ram in Wendel NC and she told me that Ram has no fix for this part, and it has been on backorder for over 2.5 years, you can have total brake failure with this part being defective, how has the NTSB not stepped in and put some pressure on them to get this fixed, there are hundreds of thousands of trucks out there with this problem. Why is it being allowed to continue for years and years without a solution??

ABS and Electric Brake failure. Second time this has been fixed. Once at roughly 30,000 miles and now again at 48,000 miles. Paperwork from dealer on both failures is “Internal Pump Failure EL001, Replace HCU. Replace old part SKU with new version…68143491AB” I entered a similar claim with you on this the first time it failed. It seems Chrysler Dodge Ram knows there is an issue based on them using an updated part this time vs last time. Also lots of internet chat forums talking about this issue. Since this is ABS / electric brakes I would think it would be a relatively serious safety concern on their part and with the federal safety agency. Why is there no recall on this yet? Aside from the obvious of preventing potential fatalities the cost of these pump failures is over $1,000 each time it happens. Thanks in advance for your help

Hello, I have an issue with the ABS Braking system on my 2018 RAM 3500 with only 50K miles on it. The lights are constantly coming on and off telling me that my ABS system needs servicing. this has been going on for two weeks. I was able to troubleshoot the problem and it says that my ABS pump and Module needs replacing. I was going to replace myself and when I ordered the parts from MOPAR they told me it was a 2 month lead time which I thought was unacceptable being such critical components to a vehicle. This week I almost rear ended another vehicle because the brakes failed. I have been online reading about the stories of these same complaints from many RAM & JEEP owners. How this company is getting away with safety issue is beyond me as this is going back to 2023, how are there no safety recalls on this not issued yet and customers not being reimbursed for the repairs. The issue was diagnosed by my independent mechanic using his scanner. If you require further info on this please feel free to reach out to me.
