The contact owns a 2026 Ram 2500. The contact stated that on three occasions while driving, the vehicle lost power and stalled. The vehicle was towed to her residence. The vehicle was towed to the local dealer but was not diagnosed or repaired. A computer update was previously completed, but the failure recurred. The dealer later informed her the failure was due to the battery. The manufacturer was contacted, who opened a Star case and was informed about a buyback. The failure mileage was approximately 200.

I was in the middle of a 1 hr long drive and my DEF gauge went from 2/3 full to empty nearly instantly. I received a message on the dash that said my speed would be limited to 5 MPH in 200 miles. Thankfully, I was within easy driving distance to a dealer, so I dropped if off yesterday (still waiting for their assessment of the issue), but what if I was in the middle of nowhere, and couldn't get to a dealer before that 200 mile limit was reached? What if the dealer couldn't see me for weeks/months which is not uncommon these days? These emissions control systems have gotten absolutely out of control and change needs to happen. 2026 RAM 2500 Laramie Mega Cab w/ approx 1,650 miles (yes, one thousand, six hundred and fifty miles)

I own a Ram 2500 (VIN: [XXX] ) that has experienced a persistent and worsening rough idle. The engine shakes violently at idle, RPMs fluctuate unpredictably, and the vehicle feels as if it may stall. This occurs at stoplights, in traffic, and after warm-up. The vehicle has been taken to the dealership multiple times for this issue. Despite repeated visits, diagnostics, and inspections, the problem has not been resolved. I was told the condition is “normal” or that a future software update may address it, but the issue continues and is getting worse. In addition to the rough idle, the vehicle has experienced intermittent electrical issues, including warning lights, erratic behavior of vehicle systems, and inconsistent performance. Similar complaints are widely reported by other Ram 2500 owners online, including rough idle, engine surging, stalling, and electrical failures. Why This Is a Safety Concern!!!!! This defect creates a serious safety risk. The rough idle causes violent shaking and unpredictable engine behavior, raising concern that the vehicle may stall while stopped or when maneuvering in traffic. Loss of power or stalling at intersections, in traffic, or while towing could lead to a collision. Electrical issues further increase the risk by potentially affecting engine management, warning systems, lighting, or driver information displays. Online forums and consumer complaint databases show numerous reports of similar issues, including loss of acceleration, stalling while driving, and electrical failures. Because the issue is unresolved despite multiple repair attempts and appears to be systemic, I believe this represents a safety-related defect that warrants investigation.

The Stereo Screen went black, unable to turn back on the dealership had to replace the entire stereo. In addition, flashing ODO and other indicators on the dash. The IDLE is out of control which shakes the whole truck. Since the screen does not work the backup camera is also off which makes it very hard to backup. The truck feels very different when the ODO is flashing and the screen is black. It is not dealer / transportation mode just FYI. The Truck was towed back to the dealership after a 16 day service visit for the first visit.
