2015 Ram 1500 vehicle speed control problems

“The contact owns a 2015 Ram 1500. The contact stated that while driving at an undisclosed speed, the ABS and the Electronic Stability Control (ESC) warning lights illuminated. Additionally, the cruise control feature was inoperable. The contact stated that the cruise control system failure had caused the ABS and ESC systems to fail. The local dealer was notified of the failure and informed the contact that the replacement parts were back-ordered. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 57,000.”

“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.”

“Subject: Request for Investigation of ABS Module Failure and Part Unavailability To Whom It May Concern, I am requesting that NHTSA 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…”

“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…”

“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.”

“The main ABS module has an internal electrical failure and shuts down. The failure affects the ABS, Traction Control, Trailer brake system and Cruise control to all be inoperable until replaced. The Module is unavailable from dealership with no known date of arrival.”
