Coolant leak, caused engine failure
My car has been getting the P092 code with check engine light, it runs really rough, i have had many parts replaced at my expense when i know the model years 2018 and 2019 have been recalled, I am many others are having the same issues, is it going to take people dying on highways because their car just shuts off. My cat has been having the same issues reported in safety recall 19V497-6744. after googling around, I may have found an answer. Denso, who makes low pressure fuel pumps for a lot of different manufacturers, recalled several million of them a couple of years ago. They determined that there was a manufacturing defect that causes the pump impellers to crack and deform. Then they don't move enough gas to the front of the engine. I guess there is no pressure sensor between the tank and the high pressure fuel pump, so the problem isn't recognized by the car until the sensor in the fuel rail sees it. Several auto makers have issued recalls, including Mazda. But Mazda only went back as far as 2018. Toyota recalled cars as far back as 2013. There are now several lawsuits against various auto makers arguing that Denso knew about the problem in 2015, and the recalls should go further back in time. These two articles do a good job of covering the history of the problem:
When I was pulling into my driveway, approx. 5-10mph with my foot barely on the accelerator, the car started accelerating on its own, almost hitting the fence. I was able to slam on the brake pedal and it stopped. It was such a hard stop, left a tire mark on the asphalt and took out some patches of my grass.
