I brought in my RV with Onan gen to have diagnosed by Cummins. As a full time RVer with pets, we had to make Airbnb arrangements for expected 1-2+ day service so this is not trivial for us to do.

It seems they couldn't locate the exact problem because they replaced both the lift pump and the fuel injection pump. I also had a cracked exhaust manifold and they said it was leaking oil and n... read more

I'm an Owner Operator of a large sleeper semi truck. Cummins offered a place to stay overnight and had water/electrical hookups for my rig. My dog was happy to greet any wonderful employees inside as we waited for our parts to arrive next day. Thank you Cummins for taking such good care of us both!
