When an ISX15 derates on the Palmetto or an ISB6.7 won't build boost in your yard, you don't want a generalist — you want someone who has had that exact engine apart before. That's the Power Diesel crew.
Answering calls day & night across Miami-Dade and Broward. Se habla español.
Plenty of shops can plug in a scanner and read you a code. Being the best Cummins mechanic in Miami means knowing which of those codes is the cause and which are just downstream noise — that an SPN 3251 story usually ends at the EGR cooler or the DPF differential line, not at a new sensor. Power Diesel has spent years on South Florida's Cummins fleet: day-cab ISB6.7 box trucks in Medley, ISL9 buses, and the long-haul X15s that run I-95 and the Turnpike every night.
Aftertreatment, EGR, VGT actuators, injector cutout tests and derate recovery — the work Cummins engines actually need.
Yard, warehouse dock, truck stop or shoulder. Most Cummins faults never need a tow to a shop.
Nights, weekends and holidays. A Cummins that stops on Sunday doesn't wait for Monday.
If you are comparing Cummins mechanics in Miami, these are the things worth asking about before you hand over the keys.

Typical on-site arrival is 45–90 minutes inside Miami-Dade and 60–120 minutes into Broward, traffic depending. We give you a real ETA on the phone before we roll, and we call again if it moves.
Tell us the code and the symptom — we will tell you what it usually means before we even arrive.
Owner-operators and fleets across Miami-Dade and Broward call Power Diesel because we work Cummins engines specifically — ISX15, X15, ISB6.7, ISL9 — on-site, 24/7, and we diagnose the cause instead of selling parts. Call (786) 395-7263 and judge us on the first job.
Almost always. A heavy-duty tow in Miami plus shop time usually costs more than the mobile repair itself, and you lose days of the truck. We fix most Cummins faults where the truck sits.
In most cases yes. Derates on Cummins engines are usually EGR, DEF dosing or sensor faults. We read the real fault, repair the cause and get you out of limp mode on the same visit when the part is on the truck.
Yes. Ram 6.7 Cummins pickups, ISB6.7 box trucks, ISL9 buses and X15 highway tractors are all regular work for us.
Typically 45 to 90 minutes in Miami-Dade and 60 to 120 minutes in Broward, depending on traffic and where you are. You get an honest ETA on the call, not a guess.
