I was traveling northbound on [XXX], just before [XXX], at approximately 35 mph on dry asphalt in my 2015 Ram 1500 3.0L EcoDiesel just after refilling the fuel tank with 13.999 gal. of diesel fuel. While the vehicle was being driven both fuel-tank retention straps broke. The fuel tank dropped from its retained position and was observed resting on the asphalt beneath the vehicle. The vehicle lost all power causing a near-miss incident while attempting to navigate out of traffic. After coming to a stop, the vehicle was moved to the side of the road and parked just east of [XXX] on [XXX]. Passenger and eyewitness [XXX] experienced the entire incident and also observed the fuel tank beneath the vehicle and the broken straps. The vehicle could crank but would not start; and the fuel lines and electrical supply were both damaged. The check-engine light illuminated, as well as the fuel low and fuel sensor fail messages occurred during and after the incident. AAA towed the vehicle directly to Byers Chrysler Jeep Dodge Ram on XXX. Dealer repair order XXX was opened XXX, and the vehicle was physically inspected on XXX. The dealer documented: “VERIFIED CUSTOMER CONCERN. CHECKED AND FOUND REAR FUEL TANK STRAP MOUNT IS RUSTED OUT. NOTHING TO HOLD TANK IN VEHICLE.” The dealer further documented that the vehicle “NEEDS FRAME OR REPAIRED FOR REAR FUEL TANK STRAP.” No recall repairs could be made; therefore the disabled vehicle was returned. The concern is that failure of the fuel-tank retention system caused the fuel tank to drop onto the roadway while the vehicle was moving. The dealer subsequently found that the rear fuel-tank strap mounting area was rusted out and that there was “NOTHING TO HOLD TANK IN VEHICLE.” I request that the federal safety agency investigate whether corrosion at the fuel-tank strap/frame attachment area can progress to the point that the fuel tank can no longer be safely retained.

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.

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.

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.

2015 Ram 1500 was driven into the garage and parked. 2 weeks later when restarted, the power steering would not work. Light in dash says Service Power Steering and also the check engine light is on. Have replaced battery, and checked all fuses, which were good. Due to the fact the truck cannot be steered, am unable to take it to a dealer for service.

I had a check engine light come on for the ABS and Traction Control. Did research and found Ram no longer manufactures the ABS Module. Now my truck is no longer safe to drive with no avenue to repair.
