My vehicle is subject to open safety Recall 67C involving the cooling fan module and related fuse protection in the engine compartment. The recall has been open since October 2025. The manufacturer and dealer have confirmed that the remedy/parts are still not available and that there is no ETA for repair. At this time, I have not experienced an obvious operating failure with the vehicle itself. However, the open safety recall remains unresolved, and because no remedy exists yet, the recall cannot be completed. This is my sole work vehicle, and the unresolved recall is preventing lawful completion of the import/registration process in Canada and preventing me from using the vehicle for work. The problem has been confirmed by the manufacturer and an authorized dealer as an open recall with no available remedy at this time. …

On June 18/19 Off Highway Van installed their 3 inch lift kit on my promaster 3500. Off Highway Van designs, manufactures and installs the lift kit. One July 23 the front right half axle (cv axle) broke or detached from the engine. The vehicle had been driven less than 2000 miles mostly highway with some city driving and 5 miles of gravel dirt road. The break happened when backing up to get back on the paved road after pulling off. Total vehicle miles is just under 18000. Safety was put at risk by the vehicle's drivetrain becoming no longer functional. I was also unable to get towed until about 4 pm the next day due. If the incident had happened while driving on the highway or at any speed it would have caused an accident. The vehicle has not been inspected. I took pictures of the damage and sent them to Off Highway Van for their evaluation. …
