2021 Newmar Bay StarEngine & cooling

1. Component failure and availability: My 2021 Newmar Bay Star 3626 motorhome, with a Ford 7.3L Godzilla V8 on an [[redacted]] chassis, suffered serious internal engine damage at approximately 15,000 miles. Metal was found in the oil and filter, and engine replacement was deemed necessary. Camshaft/lifter failure is suspected, but the engine was not disassembled to confirm the exact cause. Photographs and service records may be available; availability of failed parts must be confirmed. 2. Safety risk: The engine...

developed a persistent misfire while traveling. We drove approximately 200 miles before the problem was fully evaluated. Sudden engine failure in a large motorhome can cause loss of propulsion at highway speed, inability to accelerate in traffic, or a dangerous roadside breakdown, risking occupants and other motorists. 3. Confirmation: Ford diagnostic testing confirmed a persistent cylinder 3 misfire. Codes included P0300, P0303, P0304, P0308 and P0316. Swapping the spark plug and ignition coil/wire with another cylinder did not move the misfire. Metal was found in the oil and filter. Engine replacement was recommended. 4. Inspection: A Ford dealership/service facility inspected the vehicle and performed diagnostic testing. The engine was not disassembled for a complete internal inspection. 5. Warnings and symptoms: A flashing check-engine light and cylinder 3 misfire appeared before the engine damage was fully evaluated. The misfire persisted despite swapping ignition components. The problem occurred during travel from [[redacted]] to [[redacted]]. Metal was subsequently found in the oil and filter.

The vehicle has an intermittent problem with a severe stagger on take off from a dead stop. The problem occurs fairly infrequently, but when it does occur it can prevent the vehicle from accelerating for up to a block in distance. During this time the vehicle acts as though it is going to die and will only travel 2 - 5 miles per hour. Eventually, it will resume acceleration and drive normally. However, it is a severe danger to the vehicle's occupants since this can occur when pulling out to turn right or left...

or even go through an intersection on a green light, which might turn red by the time the vehicle decides to accelerate normally. I have taken it to the ford dealer in dallas, oregon, twice to have it repaired. They have run diagnostics on the flight recorder and have been unable to detect the problem. Since it is an intermittent problem this is not beyond the scope of reason. I have talked with a number of mechanics outside of the ford organization, and most of them have stated that they believe the problem to be the throttle positioning sensor. I have suggestive this to ford and its dealership, but they state that they cannot replace the sensor without first having the flight recorder detect the exact problem. I have offered to pay the dealership for the part and labor, even though I am still in warranty, but they refuse to replace it. In the meantime my wife and I are exposed to an extreme risk while operating our new motorhome. The dealership wants us to drive the 150 miles from our home and leave the vehicle with them to test it at their convenience while their mechanics have a lull in their daily schedule. To do this without a scheduled time with an intermittent problems could take months. I have asked ford to supply us with the loan of a ford flight recorder to use until the problem can be detected, but they have refused to do so.
