The specific issue you are dealing with is Chrysler Recall 67C (the federal safety agency Campaign 25V720). This recall impacts nearly 300,000 Ram ProMaster vans (model years 2018–2026) due to an overheating radiator cooling fan circuit that poses a significant vehicle fire risk. More than 200 of these are from the VA. Edwards Auto Group In Council Bluffs, IA is trying to make the Veterans Health Administration pay labor for a safety recall that is stated above. I am reporting them because it is a safety recall and we should not have to pay for extra cost such as a 2x4. Please see below. It is my understanding that the Dealer is in the wrong here. •Absolute Free Labor: Dealerships enter franchise contracts with the manufacturer requiring them to execute recall repairs for free. Chrysler (FCA US LLC) is legally obligated to provide the instructions and billable labor hours to the dealership. •The "2x4" Tool Excuse: If a manufacturer's official technical service bulletin specifies a specific physical manipulation or tool—even a makeshift one like a 2x4—to complete the repair, that labor time is factored into the flat-rate time Chrysler pays the dealer. The dealer cannot pass "difficult labor" or tool costs onto you. •No Deductibles or Add-ons: A dealer cannot apply any separate fees or surcharges to offset their operational challenges while resolving a safety defect.

On [XXX], while driving my 2021 Ram ProMaster 2500 at highway speed in Florida, the van suddenly lost all power and came to a near stop, then re-engaged. Vehicles were in front and behind me, creating an immediate risk of serious collision, injury, or death. I pulled over ~30 minutes, restarted, but it could not exceed 20 mph while RPMs were high. AutoZone confirmed limp mode and advised a dealer. I drove it home to Port Charlotte, then had it towed to Gettel Dodge Chrysler Jeep Ram, Punta Gorda, FL, where after two weeks it was diagnosed with a failed transmission requiring replacement. The transmission can be inspected at the dealership. No warning lamps appeared before failure. Problem confirmed by AutoZone and the dealer. I contacted Stellantis (Case #[XXXX], contact Regina Knox; dealership contact Noel), but repair assistance was denied. The van also has two active recalls, including risk of rolling out of park, unremedied. This transmission failure constitutes a serious and imminent safety defect, creating a hazard to myself and the public. I request the federal safety agency investigate this defect, compel Stellantis to repair it at their cost, and consider any further regulatory action necessary to prevent injury or death.

The 2021 Ram ProMaster 2500 I purchased from a dealer on 12/6/25 now has a serious safety defect. The transmission began grinding when shifting into Drive on 1/27/26. Immediately after, the vehicle started rolling backwards while fully in Park with the engine running. This indicates a failure of the parking pawl or internal gearset. The backup camera also does not function, there are coolant and power steering leaks, and the axle/wheel bearing is failing. The dealer claimed the van passed a “120-point inspection,” but it is clearly unsafe and unfit for operation. This defect poses a risk of rollaway injury, crash, and property damage.
