Gas Recirculation Valve (egr Valve) problems of the 2011 Mazda MAZDA6

Vehicle has a 3. 7l v6 duratec engine designed by Ford. I was entering the highway at about 55mph, check engine light went on, then vehicle shut off, and I lost both power and steering. Was able to get to side of the highway without crashing. Steam/smoke was coming out of the hood and the temp gauge was pinned at h. Dealership advised that coolant had gotten mixed with oil and engine was destroyed. Cost to repair - $7400 used $13k new engine. Told it was not due to any neglect or maintenance issue. It was a water pump failure. There is a design flaw in this engine. The water pump is integrated into the engine and timing chain. When the pump fails it damages the engine, allowing coolant to mix with the oil. Numerous Ford and Mazda owners have had this problem but because it usually happens at or after 100k miles the manufacturers do not report it. They will also do nothing to help the customer who is left with a huge repair bill or a totaled car. Please help me and other owners. I have research with the names of other owners who had the same problem with their Ford or Mazda.

The ac compressor clutch locked up and caused the belt to make loud screeching noises. Also, something burning could be smelled inside the engine and burnt rubber was flung around the engine compartment. Another issue: read about this a lot because I am experiencing it, the passenger-side dash is melting. Seems they used a cheap material and when it gets above 80 degrees outside the dash begins to melt. It is sticky, leaves a residue on your fingers, and produces an extreme glare. The ac went out while I was in the drive-through ordering food. The dash board has been melting since last summer and has not gotten any better. Stopped melting during the winter and began melting now that it's summer again.
