The ABS, Traction Control, & Trailer Braking system no longer function. The vehicle is still drivable, technically unsafely. Warning lights for these system on all the time. I took vehicle to my local repair shop and was told the ABS Controller Module has failed (code C2200-49 indicating an internal electronic failure within the controller). I was quoted a replacement cost of $1579 + tax. I was also told the part, 68228991AD is on indefinite backorder. I have tried to locate the part on my own and there is in fact a nationwide backorder. As of this date replacement and remanufactured modules are not available. This is not just an issue with 2015 Ram trucks but extends to other Ram model years using the same part number. This is a huge safety issue that should be addressed through a recall. It is a travesty that Ram would not maintain adequate supplies of essential safety-related repair parts for a vehicle that is only 10 years old. At this point I have no recourse except to drive the truck in this condition. I am unable to sell the vehicle due to this situation.

While driving on the highway with my entire family in the vehicle, truck lost power without warning and what it seems it went into a limp mode. This created an incredibly hazardous situation, exposing my family and the drivers around us to an imminent risk of a high-speed collision. Thankfully, nothing happened and no one was hurt. Upon restarting the vehicle, the check engine light illuminated, and power was drastically reduced, capping our speed at approximately 40 mph. I brought the truck to St Charles's dealership for diagnosis. Service department has informed me that the root cause of this catastrophic failure was the crankshaft tone wheel. Furthermore, I was informed that this specific issue was an unaddressed/unfixed defect on my vehicle by Stellantis. What I learned is that the fix for a broken tone wheel required dropping the transmission to physically press a brand-new tone wheel onto the crankshaft. Because this was incredibly expensive and time-consuming, Chrysler rolled out a recall remedy consisting of a Powertrain Control Module (PCM) software flash.This should be unacceptable for trucks that cost $70,000 or any vehicle. Imagine that software failed what would have happened and yet we had no idea about this.

Subject: Request for Investigation of ABS Module Failure and Part Unavailability To Whom It May Concern, I am requesting that the federal safety agency investigate a potential safety issue involving the Anti-Lock Brake System (ABS) Module, Part Number 68228991AD. The ABS module in my vehicle has failed, causing the ABS and cruise control systems to stop functioning. In addition, the ABS, check engine, and brake warning lights remain illuminated at all times. As a result, the vehicle no longer has anti-lock braking capability, which increases the risk of skidding and loss of control during emergency braking or adverse road conditions. My primary concern is that this safety-critical part appears to be discontinued or otherwise unavailable. I have spent more than three years attempting to locate a replacement through dealerships, parts suppliers, salvage yards, and online sources without success. Because the required part cannot be obtained, owners are left driving vehicles with a disabled ABS system for extended periods. This creates an ongoing safety risk for drivers, passengers, and others on the road. A critical safety system should be repairable when it fails. This issue has also created a significant financial burden. The constant warning lights and inoperable safety features substantially reduce the value of the vehicle and make it difficult to sell or trade. Few buyers would be willing to purchase a vehicle with persistent ABS, brake, and check engine warnings that cannot be repaired due to the lack of available parts. I respectfully request that the federal safety agency investigate the frequency of failures involving ABS Module Part Number 68228991AD, the availability of replacement parts, and whether manufacturer action, including a recall or extended support program, is warranted. Thank you for your consideration and commitment to vehicle safety.

The ABS module failed in June of 2025. Ram originally told me the part was on back order 6-8 months. In December they said there were 100 ABS modules on order for our area. In January 2026 they informed the mechanic that is doing the work that there is still parts on back order and it could be another 1-2 months. Today 2/25/26 the mechanic was told there are 265 modules on back order and it can be another 2-3 months. The truck now has a throttle body control issue that is stemming from the ABS issue. The truck is not operable at the moment because of this back order. I have been waiting for 7 months for this part and there are no alternatives on the market. If Ram does not get a part available for me I will either have to find a used one that hopefully isn't going to fail or be out of a $50,000 truck. This is a problem that many people have had according to all of the RAM forums. RAM needs to find a solution because the consumer already paid for the vehicle so parts should be available.

ADDITIONAL INFORMATION There is a design flaw in the ABS Module for these vehicles that causes them to malfunction. This issue affects thousands of Ram vehicles. The chip in the module that is defective is no longer being produced, and Stellantis is unable to provide replacement ABS modules at the rate they are needed. Thousands of these trucks are driving around with no ABS, T/C, etc or are sitting in shops waiting for a new module, as they will not pass state safety inspections. Stellantis will not acknowledge there is a design flaw with these modules, even though they have been listed as being under "Engineering Review" for multiple years. Due to the critical vehicle systems that are impacted, these ABS Modules must be recalled.

While driving at approximately 50 mph, my truck suddenly shut off without warning. I lost engine power, power brakes, and power steering. I was only able to stop safely because I happened to be traveling uphill. This created a serious safety hazard. The failure was caused by the crankshaft tone ring issue addressed in the existing recall. The tone ring has already been replaced, but the recall requires a dealer-performed ECM software update to complete the repair and ensure the vehicle is safe to operate. The dealership is refusing to perform the recall software update because my truck has an aftermarket exhaust and a modified EGR valve. These modifications are unrelated to the recall. The recall only involves an ECM software update, and my ECM is completely stock. Because of this refusal, I cannot safely drive my truck. I am concerned that the engine may shut off again at higher speeds, creating a severe risk of an accident. I am requesting assistance to ensure the recall is completed so the vehicle can be operated safely.
