2015 Ram 1500 Electrical System Problems

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.

Ram trucks have a known problem with the ABS module. When this system fails the truck loses it traction control. It has been known for years, but Ram truck continually states it's under engineering review. Per the dealer in Jacksonville, FL., there is no solution and no parts to fix this issue. My truck only has 61,000 miles and I've lost my ABS, traction control, cruise control, and 4-wheel drive.

The Antilock Brake Module (part # 68228991AD) and Antilock Brake Hydraulic Pump (part # 68196033AA) have failed for no apparent reason. The dealer states there's a national backorder for the module with no delivery date noted. The module controls the anti lock braking system, traction control, and cruise control, which are all safety concerns. The module cannot work without the associated pump. This problem has been confirmed by two dealerships and an independent service center. There were no warnings prior to the failure, which occurred on 10/18/25. The cost of the pump is $1290 from the dealership, which is outrageous. There are remanufactured modules and pumps out there, but they are outrageously priced. I'm thinking about going the remanufactured route to address the safety concerns this causses though.

I am experiencing ABS issues on my truck. After visiting a local auto parts store to get an OBD scan, the code says it’s a bad ABS module. I called the dealership to share this information and they confirmed the code from the auto parts store is a bad ABS module. They said “oh no, you got that code huh? You’re not the only one.” The reason for my visit was because three lights were illuminated on my dash. The ABS light, the traction control light, and the BRAKE (trailer brake) light. The messages on the dash display say to service the ABS system, service the electronic braking system, and service the trailer brake system. From my research, I have discovered that many people are experiencing this same issue on similar vehicles . So much in fact that the parts for repair are unavailable at the dealership and online warehouses. The cruise control is disabled while experiencing this issue and braking performance is affected while driving. I’m afraid that my brakes will lock up on me in a hard stop event and lead to an incident.

The Starter of the truck seems to have "shorted" and started an electrical fire that burnt the wiring harness leading up to the battery including part of the battery cover. Drove truck on 100 mile trip. Arrived, parked. 2 days later went out to truck to drive home. Turned key, check engine light came on. Service electronic throttle control light came on. Opened hood, smelled burned smell. discovered battery cover and harnessed burned. Disconnected and removed battery. Had truck towed 100miles home. Went to mechanic who traced the burn down to the starter. He replaced the starter and showed me where the fire started. FYI I called the service manager at Berthod Ram in Glenwood Springs Colorado to ask if they would like to see the Starter, left message. THEY DID NOT REPLY.

The issue started with ABS, Brake, and Traction Control lights coming on intermittently. Leventually they stayed on all the time. Cruise Control is disabled while these lights are on and the ABS system is obviously not working. The dealership stated that it was the ABS control module and states that the part is discontinued and they advised that they didn't have any more parts in stock in addition to quoting around 3k if they could find one at any other locations. All fuses are working properly. And all codes that are pulled indicate ABS system faults.

The ABS module has malfunctioned and needs to be replaced. It has been months and the dealership/chrysler is unable to provide parts for the repair.

What component or system failed or malfunctioned, and is it available for inspection upon request? ABS Control Module (Part Number 68228991AD). Failure of this part prevents the ABS system, trailer brake, cruise control, and traction control from functioning properly. Part is currently installed into vehicle and is not available for inspection. How was your safety or the safety of others put at risk? Car no longer has ABS, traction control, trailer brake, or cruise control. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. This is a know issue with 2014-2016 Ram 1500s. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. Following lights are on dashboard: Brake, Traction Control, ABS. OBD Code C2200 for internal module failure. Lights were first intermittent in the Summer of 2024. Came on permanently in early 2025. 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.

Issued I have had with this vehicle was the camshaft , started shaking and missfire as I was driving heard from other ram owners that this is a common issue on 3.6 ltr The other was an electrical wiring harness that's goes to the engine I have a knob gear shifter as I was driving vehicles. Switch to park and dashboard read something like stop vehicle and restart to shift gear . I thought I had moved it by accident . Next day drove from la, to thousands oaks . Trip started fine till I got to my destination by the grace of God I made it asoon as I parked it all the lights on my dashboard came on traction control throttle body automatic brakes crankshaft sensor and I forgot what else had it towed to LA to mechanic shop where it took them about 3 -4 weeks to pinpoint the issue the esults were the wires were melted and corroded you could see the green residue all along the wire harness. I'm grateful it ain't catch fire or stop on the highway in the middle of the freeway

About a year ago my vehicles auto traction , brake light and abs light illuminated. The warning that my vehicle gives when I turn it on and start is braking system needs serviced and electrical breaking system needs serviced. The code that shows in diagnosis is abs brake module needs replaced. My brakes have not been right. The part has been back ordered for over a year. There are no parts and my dealer and Ram answer is it’s under engineering review till January 15. The dealership answer is get one from the junk yard which they’re aren’t any. I wouldn’t feel confident driving my grand babies with used brake parts. I was in an accident today because of brake failure and thankfully I didn’t hurt anyone in the car in front of me.

Air bad for rear seat warning light. I can’t drive with my kids in vehicle. Erratic fuel issues stalling bad computer gives faulty reading. Cause me to get in necessary maintenance. Suspension issues always shakes on highway.

No power going up hills, won't shift going down hill, park sensors lights come on, zero oil pressure then Electronic Throttle. From what I seen on internet and from others with the same issues it's due to high pressure fuel pump which has a recall on it. But when it was sold by the dealership in November 2023 the dealership said there was NO open recalls. But then I find out there is an open recall for the high pressure fuel pump. Now this issues keeps going on. And today September 6 2024 my vehicle lost all power and the fuel light and Electronic throttle Warning light came on and if I had not been in the right Lane and a turn in I would have been hit from behind!

Was driving to store got to store came out vehicle won't start just keeps turning over. From others that have the same vehicle ecodiesel I'm told it's the tone wheel/crankshaft position. And that the cheap plastic housing chips which causes the no start. Also recall for high pressure fuel pump. And the closest dealership to me can't get my vehicle in for over a month and won't provide a loaner vehicle. I'm well over 2 hours from any other dealership. I bought this vehicle from a dodge ram dealership and was told "NO RECALLS PRESENT " they even had me sign a paper that stated that and gave me a carfax that so no recalls and no recalls ever. But turns out there are 18 recalls for this vehicle. Bought thus vehicle November 2023. So now this vehicle is sitting in my driveway not running and can't get it fixed because the closest dealership can't because they have 1 ONE technician, and no other dealership will tow it to get fix free of charge. All of the symptoms are related to both recalls. High pressure fuel pump, and tone wheel /crankshaft position. Lastly a LOT of people are having to replace the intake manifold regardless of milage for this type of motor.

The contact owns a 2015 Ram 1500. The contact stated while driving approximately 30 MPH, the check engine warning light was illuminated. The contact stated that the vehicle stalled. The contact was able to stop and had the vehicle jumpstarted. The contact had taken the vehicle to an independent mechanic who diagnosed the vehicle and determined that the battery needed to be replaced. The contact advised the mechanic that the check engine warning light was illuminated for almost one year prior to the failure. The vehicle was repaired; however, the check engine warning light had been illuminated. The contact called a dealer who advised the contact to bring the vehicle to the dealer for a diagnostic test to be performed. The contact had not taken the vehicle to a dealer, and the vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was 64,545.

ABS Module failed triggering BRAKE light service and ABS Service light, and the ESB light. 6 month + and counting to get this OEM module. Why are you not addressing the supply chain issue......

In August of 2024 I began receiving an error message in my vehicle stating "Service Electronic Breaking System" on the gauge cluster. I also noticed the dash lights indicating that the ABS and traction control were disabled. The vehicle remained in this state whenever the vehicle was running. While i was returning home from work i hit the breaks on the freeway and the breaks locked up and i began to slide due to the ABS not functioning properly. Thankfully there was no accident but obviously this is extremely unsafe and the vehicle cannot be driven in this condition. I made an appointment on August 26,2024 to have the vehicle inspected and serviced at the dealership where i purchased the vehicle. After some correspondence the service rep indicated that there were other vehicles in for service for the same issue. It is now 28 Jan 2025 as of the date of this submission and my vehicle has still been able to be repaired. After numerous inquires with the service department i was informed that the module in question was under Engineer Review at the manufacturer and they could not ship the part until that was complete. The ETA of completion has been pushed back several times ,everytime i enquire for an update and is currently projected at 19 February, I have also opened an inquiry with the manufacturer Ram Customer Care / Stellantis case for assistance and havent received much in the way of additional information or assistance.

ABS, Brake, and traction light came on. Took my vehicle to dealership for diagnostic. The dealership stated it was caused by internal failure to ABS module and HCU. Parts are not available for repair due to parts engineering approval. This is a safety issue were the brakes could fail. Manufacturers should be responsible for repairs and recall vehicles for safety issues. How can the dealership say ABS is unavailable to order.

Upon startup the vehicle routinely fails to load the infotainment/center console. This failure prevents the operator from seeing the rear view camera. Nothing in the console comes online for several minutes and other times it loads just fine. It has occured on my truck more than 50 different times.

Service ABS Brake, Service Electronic Brake Throttle, Service Electronic Trailer Brake & Standard Brake dash lights are illuminated at all times. I have no Anti Lock Braking & Sway /Stability Control Light is on and I have No Stability nor anti sway control. This disrupts the Cruise Control from working. It has been confirmed by a local trusted mechanic shop. The Warning Lights have been on since June 2024. This is dangerous especially in rain and wet conditions. The truck has no traction control and fish tails at the slightest turn during acceleration.
