NHTSA Complaint #11697894 — 2025 RAM PROMASTER

Check engine light came on the 2nd day I owned it. The van was converted to an Entegra Ethos Class B RV by Entegra/Jayco, and had over 2000 miles in it when I bought it (New 2026) from La Mesa RV in Tucson AZ on Oct 4, 2025, after they transferred it from the Phoenix La Mesa RV location. After checking the engine light code with an Auto Parts store, it was shown to be an issue with the 6th cylinder. After getting the runaround from 2 Dodge dealers (system down, too busy, no certified tech), I took it to a privately owned garage who diagnosed low compression in the 6th cylinder. They were concerned for my safety to drive it. With this testing info written by the private garage, I got the Dodge dealer in Tucson to take it in and start the diagnosis process. It is an engine defect from initial manufacturing of the engine. Still trying to work through the repair process and the van is still with the dealer. They are trying the easiest and cheapest parts in succession to try to get it passing. This is a safety hazard and will likely cause long term problems, per friends with automotive experience. I'm assuming this van isn't the only one with this issue right off the manufacturing line.
