Manufacturers Service Center (local and ONLY Ram dealership) has reproduced the issue. Independent Diesel Mechanic shop also reproduced. Service center and Independent shop both inspected. The safety issues of a 5 MPH limp mode and risk of sudden engine stalls while driving in traffic, especially on an interstate should be fairly self explanatory… As is a constant “Power Reduced See Dealer” problem, when your truck is used to do what it’s designed to do… Tow large loads. As is an extremely loose gear shifter that doesn’t always properly register as “in Park”. The date listed below is simply the date of the very first occurrence.

While driving Down a paved roadway on 6/30/23 @ 5pm doing approximately 20 miles per hour the vehicle died and the dash lite up with every single message possible such as 4WD inactive, oil change due, fuel filter service required and etc. Attempted to restart the vehicle for about 25 minutes when another citizen noticed we were having issues with the vehicle so they stopped to assist us. The citizen towed my vehicle to location we were staying at for the weekend and upon arrival to the location I disconnected both battery terminals to allow the computer modules to drain/reset. After allowing the batteries to be disconnected for several hours I hooked them back up and tried starting the vehicle and was unsuccessful getting it to restart. I disconnected the batteries again for the night and returned the next morning to hook them up. after hooking the batteries back up, I was able to get the vehicle started and moved it around at the place we were staying at and allowed it remain running for about 20 minutes before I shut it off. Went and did other projects and about 5 hours later returned to the pickup to see to see if it would start since we were heading back the next morning and it started so I figured it would get us home on Sunday July 2nd. On July 2nd @ 11:30am started the pickup to leave and everything seemed normal. We drove about 5miles from the location we were staying at and were approaching an intersecting highway OR58. I proceeded out onto OR58 westbound and as we got about 1 mile down the road when the pickup died and every message was being displayed again. As we sat way off the shoulder of OR58 incident response pulled up behind us to make sure everything was ok. I told the incident responder that we were good and I was working on contacting RAM for a tow. About 15 minutes had passed and IR person walked away then the pickup started. I was able to drive the pickup about 2 more miles down the road when it died again and had to be towed.

My check engine light went on, along with the DEF warning, early June 13th,2023. The DEF warning stated I had 150 miles to get the Track to a Dealer. After Dealer evaluation, I was told the truck had DEF contamination, from ,Diesel Fuel. I asked how this could happen? I was not given an explanation. To me this is a DEF Pump failure. The DEF Pump did not have enough PSI to inject DEF into the Diesel Fuel, so the Diesel Fuel back flowed into the DEF system. Additional facts, my Truck warranty expired 5/15/2023. My truck has less than 36,000 miles. I had the High Pressure Fuel pump, Recalled fixed in May 2023. I was told this repair did not lead to this issue. The Repair bill is over $3700 for this repair.

My high pressure fuel pump went out while I was towing the 43 ft enclosed trailer causing the engine to shut down. I was able to get it home and onto a car hauling trailer took it to a dealership and confirmed the high pressure fuel pump was the culprit they informed me that they would not perform the safety recall because of a modification to the vehicle which has no bearing on the safety issues at hand I contacted FCA they encouraged me to take it to a different dealership which I did. I had to pay a tow truck to haul it to another dealership in which they told me they would do the recall however when they put my VIN number in their system my pickup had been blacklisted by the parent company Chrysler saying do not work on this vehicle for safety recalls. I at this point got quotes to have it done and it was extremely expensive to friend advised me to look into the law so I contacted a lawyer and they told me to file a complaint with the federal safety agency.
