I am the owner of a 2018 Ram 3500 subject to Recall C4B (the federal safety agency Recall No. 24V‑896) involving the Brake Hydraulic Control Unit (HCU). The recall was announced on November 27, 2024. As of June 2026, the federal safety agency’s website still states that the recall is incomplete and that a remedy is not yet available for my vehicle. The defect causes active symptoms during operation. The vehicle continuously chimes while driving, similar to a seatbelt warning, and cruise control is disabled. These symptoms substantially interfere with normal operation, especially during long trips and towing. I have contacted authorized Ram dealerships and Ram Customer Care multiple times. Dealerships state that no remedy is available and refer me to Ram Customer Care. Ram Customer Care confirms that no remedy is available and provides no repair timeline or meaningful resolution. Most concerning, neither the dealerships nor Ram Customer Care will initiate a repair attempt because no repair procedure or parts exist. Owners are therefore unable to obtain repairs or even establish documented repair attempts despite the existence of an active safety recall. I was also advised that I could rent a vehicle at my own expense and potentially seek reimbursement if approved. Given that this recall has been open for more than 18 months with no available remedy or repair timeline, expecting owners to personally fund rental costs for an unknown period with only the possibility of reimbursement is unrealistic and inadequate. This open safety recall has negatively impacted the vehicle’s usability, resale value, and trade-in value while preventing owners from obtaining a repair. Stellantis acknowledges the safety defect, yet no practical remedy or alternative solution is available. I respectfully request that the federal safety agency review the continued lack of an available remedy, the extended delay in repairs, and the absence of a meaningful process for affected owners to obtain relief.

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.
