I was Driving down the highway at 45-50 mph when the truck suddenly the engine started to rev very high approximately 5000-5500 rpm and the truck lost all Drive gears. I immediately put it in neutral and tried again to put it in drive and nothing happened. I immediately pulled over to the shoulder and shut the truck off. I waited and restarted the truck but the truck did not have any movement in any gear. I had to get it Towed to a local shop.

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. They claim their modifications did not cause the problem. I do not believe them. I think the traction control light might have come one when the cv axle broke. No other indicator was active. The vehicle was towed to my home and is still there untouched.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Ram Promaster (passenger Double Seat) verdict →
