This is certainly the exception to the rule, as MOST dealerships won’t cover ANYTHING on a car that’s modified for track use. Hell, I’ve seen a GT350 owner with a grenade engine get his warranty claim denied because he had a rear wing and front splitter, even though the whole rest of the car was stock. Dealerships certainly will void entire powertrain warranties over things like exhaust/intake mods (things that Mach 1 come stock with), coolers (diff, trans, engine oil), wheel/tire changes (citing increased stress on powertrain components due to increased grip)... hell, I’ve even had a dealership threaten to void my powertrain warranty because I asked them to put in 5W30 oil instead of 5W20!I know it’s different from dealer to dealer, but the service tech at my local Ford dealer has told me repeatedly they’d honor the powertrain warranty so as long as I hadn’t modified anything on the powertrain. I’ve upgraded suspension components on all three of my past Shelby‘s and had TSB fixes done to the clutch and transmission and they never said anything about the obvious addition of a Watts bar and adjustable swaybar links.
I’ve also heard of people having their warranty voided for admitting they take their car to the track. Since the Mach 1 is being advertised as a “track capable” car, you’re probably less likely to encounter issues in that regard... so that’s a definite +1 for the Mach 1 in my opinion.
It’s scenarios like that that push me towards wanting a Mach 1, because while I can afford to replace an engine on my own, I’d rather not HAVE to do it on a relatively new car, ESPECIALLY when it wasn’t caused by any sort of negligence. And with the line of work that I’m in, I rarely stay in the same city, let alone the same state, for more than 5 years, so it’s more than just finding a good dealership. This wouldn’t be the case if Ford dealerships in general were more inclined to work with their performance-minded customers, but such is life
