Driving 55mph on highway when, the vehicle began to shudder abnormally, resulting in pulling over to the shoulder of the interstate. Took vehicle to mechanic and learned oil coolant housing was leaking. This is a known design flaw by the manufacturer which can lead to engine damage and/or sudden stops of performance while driving.

We purchased the van in April 2024, and the mileage was 130268. We checked the oil regularly and noticed the level dropping. After driving it 3080 miles and checked the oil level after letting the vehicle sit over night. The oil level was down almost 2 quarts. I contacted the dealer and told them what happened and they mentioned that there was a recall for some Promaster City vans. I looked up the information and found the recall marked as W80. I contacted Chrysler and they said our vehicle isnt listed and to contact the federal safety agency. It has the same problems and is losing the oil in the same amounts as specified in the recall but for some reason, our VIN isnt listed in the recall.

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.

I took the vehicle into a ram dealer service center because the 'fill def' light and message remained in the evic even though the def was full. The dealer determined that the issue was the egr cooler, tube and gaskets need replaced. The repair was quoted at $2918.27 (see attachment). Upon researching mopar safety recalls, I came across recall vb1, which pertains to egr coolers of ram 1500s with ecodiesel engines needing replaced. I called mopar, and they said vb1 does not apply to my VIN, even though it is the same engine. I am wondering if vb1 is the same issue I am having with my promaster 1500 with an ecodiesel engine, and if any other promaster owners with the ecodiesel have had similar problems. The cost of this repair is too high to justify paying for it, and in all honesty, is too high to justify having bought this vehicle in the first place, especially if other ecodiesel vehicles are having this exact same issue.
