I had the federal safety agency recall for this generator done (23E-030) which was to solve the same problem I just had. Apparently, they just moved to a smaller diameter fuel line to fit the fuel pump better. However, this hose also came off my Cummins generator fuel pump and was spewing gas all over the generator and the ground when we ran it. This is a very unsafe condition and I'm surprised, after the recall was performed by a certified Cummins dealer (verified by Cummins) that this "new" fuel line has also come off the fuel pump.

My 2021 Ram ProMaster 2500 has two open safety recalls with no remedy available: the federal safety agency Recall 25V‑552 (rearview camera FMVSS 111 compliance issue) issued August 26, 2025 the federal safety agency Recall 25V‑720 (cooling fan fire risk) issued October 23, 2025 As of April 2026, no remedy has been provided for either recall. The vehicle is used commercially for rental income, and the lack of a repair has caused financial loss of approximately $500–$1,000 per month. One of the recalls involves a potential vehicle fire risk. The prolonged delay without a remedy is concerning for both safety and financial reasons.

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.

The rearview camera intermittently fails when the vehicle is shifted into reverse. The image flickers, becomes distorted, upside down, or goes completely blank. This is a known issue covered under Recall #59C, but the dealer stated there is currently no available remedy. The failure makes backing up unsafe and unpredictable.

The vehicle experienced a sudden and complete loss of steering control during normal driving on a public roadway. The steering wheel became extremely difficult to turn, and the vehicle became immobilized, creating a serious risk of collision and injury. The vehicle was towed to an authorized RAM dealership, where inspection confirmed a broken serpentine belt, abnormal alternator noise, and metal contamination throughout the entire power steering system. The dealer advised that the entire power steering system requires replacement. The presence of metal debris in a critical steering system indicates a pre-existing mechanical defect that could not reasonably develop within 27 days of normal use. No warning lights or messages appeared prior to the failure. At the time of sale, the vehicle was also subject to unresolved safety recall(s). The selling dealer refuses to rescind the sale or provide a refund.

This is in regards to cooling fan overheating and causing fire. My closest dealer scheduled me for the recall knowing why I was coming in. When I arrived they told me it was a lengthy repair but confirmed it would be done by the end of day. I changed my plans around this and when end of day came they said the did not have the parts on hand to complete the recall and needed to order them but confirmed the vehicle indeed needed the recall parts. why would they schedule the service, check on the timeline, and then figure out they didn't have the parts? I was down a work truck, work day, transport cost to and from dealer, added an oil change because I would be there only to be let down like this. I have heard nothing from the dealer as a follow up on getting this resolved

The vehicle suddenly and without warning experienced a complete loss of steering control, rendering it undrivable and forcing it to stop on the side of a public roadway. This created a significant risk to my personal safety and to public safety. On the same day, the vehicle was towed to an authorized RAM dealership for inspection. The dealership confirmed that the serpentine belt had broken, there was abnormal noise from the alternator, and the entire power steering system was internally contaminated with metal shavings, requiring complete replacement of the power steering system. The selling dealer has refused to accept rescission of the sale and has also refused to cover the necessary repair costs. The vehicle was unlawfully sold to me while it was subject to an unresolved safety recall, demonstrating a serious disregard for my safety and the safety of others.
