I hope this lack of good will from Mazda for this water pump engine failure is due to this being Ford/Mazda issue and Mazda will stand behind their non-Ford "Mazda" product.
I hope the lawyers get a better settlement than what Nissan Xterra, Frontier, Pathfinder owners got from Nissan for the SMOD (Strawberry Milkshake of Death) and timing chain tensioner failures. Nissan just extended the warranty a little for the SMOD failure knowing full well the automatic transmission fluid cooler in the radiator WILL eventually fail/leak and kill the automatic transmission. Nissan should have replaced the radiators for affected years once they realized the designed flaw in the radiator. Nissan basically testified in court in the timing chain tensioner lawsuit that their engine is only designed and expected life is 100,000 miles to justify why that pro-rated extended warranty settlement only goes up to 100,000 miles. I've sworn off all Nissan products. Not even using any Nissan parts or fluids for maintenance. One of the reasons Nissan was not a consideration when we eventually bought our 2016 CX-9 GT.
In my experience, *dealers* are the ones who can make or break your chances of getting a goodwill repair. If you didn't buy the vehicle there, and especially if you don't have it serviced there, dealers have little incentive to help you out. That has been my experience across domestic, European, and Japanese brands of vehicles. The dealers, of course, will try to tell you that they have little influence and the customer has more leverage with the manufacturer directly, but that makes zero sense and is not consistent with my personal experience.
I had (and still have) a Nissan product which qualified for the timing chain issue and the SMOD. I don't recall the timing chain issue resulting in any failures, but it did generate a notable whine in affected engines. I experienced that one, and even though the dealer "couldn't hear it," they agreed to do the work right before the warranty ran out. I did *not* have the SMOD, but again the dealer helped me out and replaced the radiator proactively before the extended warranty ran out (around 80k miles, IIRC). I still had the transmission fail at 145k miles for undetermined reasons, which I pretty much had to have replaced at the dealer due to nuances with that particular transmission. And yes, I had all of the ATF and driveline fluids changed at prescribed intervals by the dealer. Still, our two Nissan vehicles have better service records than our previous Jeep, Audi, Honda, and Subaru vehicles.
My observation is that pretty much all manufacturers treat customers as a whole about the same. Class action lawsuits rarely provide any material benefit to consumers, but almost always provide a nice payday for the lawyers; that's not an indictment of the lawyers so much as it's the nature of that type of litigation. I wish that I could rely on manufacturers to fix their defects on vehicles sold, but none of them do a great job in that regard, though some (such as Honda and Toyota) seem to do better than average. Those folks who will "never buy that brand again" are simply going to move to another brand where they likely will be treated approximately the same under similar circumstances.
