2018 TIFFIN ALLEGRO BREEZE Complaints

On Sunday, May 21, 2023 we were traveling e/b on Highway 40 in Albuquerque when an amber mil light and check engine light appeared on the dash followed with sluggish engine performance. We exited the highway (#175) and pulled over. SPN 94 FMI 17, SPN 157 FMI 18. After about 15 minutes and engine restart only the mil remained. We got back on the freeway and the event re-occurred. A mobile mechanic replaced the fuel filters and cleared the faults. We continued on. We exited the highway at Flying C Ranch (#234) and while exiting the event re-occurred. We spent the night in the parking lot and the following morning I called [XXX]. [XXX] told me that the codes were related to the fuel rails and that I needed to go to Cummins. I called Rocky Mountain Cummins and made a service appointment. Re-started the coach and only the mil remained. Upon traveling w/b 40, the event re-occurred and was able to make it to Clines Corner where we spent the night in their parking lot. Hoping to avoid a tow, the fuel filters were once again changed out. On Tuesday, May 23 we experienced a complete loss of power at the Wagon Wheel exit unable to make it off the Highway. We were towed to Rocky Mountain Cummins by [XXX] from Taverner's Tow. Rocky Mountain Cummins diagnosed the problem as a faulty fuel actuator and completed the repair on June 5. We left that afternoon and after passing mile marker #261, the same event re-occurred losing all engine power & no restart. We coasted to the shoulder where we remained during a rainstorm for 14 hours awaiting a tow. Rocky Mountain's "trouble shooter" diagnosed the problem as a "broken wire" near a connector and make the repair. On each of the events the same SPN & FMI fault codes. The following week I attended the [XXX] presentation at the [XXX] in Amana, Iowa. The [XXX] speaker said that an amber check engine light and mil light is not a cause for immediate concern and continued driving is fine until next fuel stop.
