Several incidents when accelerating, the engine goes into a limp mode, followed by indicator lights coming on P0401, P0299, P226C. The vehicle will not accelerate and travels at a max speed of about 5mph. This has happened in traffic every time and has put me and my family, as well as other vehicles, at extreme risk of being in an accident, not being able to accelerate out of the way of oncoming traffic. After several cycles of turning the vehicle off and on, it returns to normal function. The vehicle has been inspected at a Dodge Service station. They determined that the Turbo diesel system is malfunctioning and needs repair. My vehicle is available for inspection upon request.

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 2015 Ram Promaster (passenger Double Seat) verdict →
