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.

While on vacation in nm and co, an engine cooling fan on safety recall (our exact model, make, and year and accessories) was blowing fuses/malfunctioning - the result possible is the same thing that initiated the recall - possibility of fire. Blown fuse also can result in limp mode being executed in a dangerous driving situation, (slick roads, steep mountains, curves not to mention $1000's of dollars of unnecessary repairs because it also falsely affected the diesel particulate filter. Vehicle was in motion and on highway and smaller roads - it happened out of blue each time the attached document shows same cooling fan recalled - dealer refused to replace saying our VIN not on the list but obviously it is having problems and replacing it is what fixed the vehicle thanks

My exact vehicle ram promaster i4 3l turbo diesel with factory air is on a safety recall for bad coolant fan, but chrysler is saying that my VIN does not qualify. The chrysler dealer tells me I need to replace my cooling fan because it is shorting and blowing the fuse and possibly affecting the relay also. This fan code is also putting the van in limp mode and not allowing the diesel particulate filter to be regenerated. Here is the link for recall that I found please help or at least let me know what recourse I have - it's pretty obvious this fan has issues and 2015 was one of the 1st. - the whole engine and emissions is tied together by the computer and sensors so 1 thing affects many thanks [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

2015 ram promaster city currently has 715 miles on the odometer. We have owned this vehicle for 3 months, and purchased it new. The problem I'm about to describe has occurred on four (4) separate occasions in the last 3 months. While vehicle is in motion, (has occurred between 25 MPH and 75 MPH) the transmission clunks loudly, and is met with a sudden loss of engine power. Each occurrence forced us to pull vehicle to side of road, (3 occurrences on city streets, 1 occurrence on freeway) turn the engine/ignition off, and start engine again. Once engine was restarted, vehicle allowed us to drive in what the dealer has dubbed "limp-in mode" where vehicle allows itself to be driven at 25-30mph, and will not shift gears. Each trip to the dealer revealed different odm service codes. Each time dealer returns vehicle to us, claiming they have fixed the issue, the issue inevitably occurs again. Dealer has claimed to have repaired 3 different modules, none of which have solved the problem. Still awaiting repair for this fourth occurrence.
