The check-engine light came on my 2nd day of ownership (less than 100 miles driven by me, but 2032 miles on it when purchased new - RV conversion from Entegra Coach through LaMesa RV), on October 5, 2025. After diagnosis at a Ram dealership (Larry Miller Dodge Ram in Tucson AZ), they identified the code was misfire on cylinder 6, which caused low compression, with a root cause of the intake valves being improperly seated during manufacturing. The dealership replaced some cylinder and engine parts, but the issue recurred on Cylinder 4 after driving it about 5000+ miles, on June 13, 2026. Again, misfire check-engine code and loss of compression on cylinder 4. The engine ran very rough and had

whenever I was driving on the highway at 80MPH it felt like someone stepped on the brake pedal abruptly for a split second and the car with squiggly lines behind it appeared on the instrument panel, then disappeared.

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 Dodg
