NHTSA Complaint #11436698 — 2012 MAZDA MAZDA3

my power steering has randomly failed for a second time. It happened once before as I pulled into a store -this time it happened while I was travelling southbound on highway 1 a very curvy road with steep cliffs where the speed limit is 55 so it was very scary when my steering suddenly went to manual steering. Turning the car off and waiting a few minutes seemed to remedy it. I continued to have a check engine light which cleared the next time I turned the car off. The power steering pump is an electric hydraulic pump so no belts involved. No weird noises just sudden scary failure. I researched on Mazda forums and found quite a few others with similar complaints and having spent money on dealers with no resolution. The car has 65k on it. The mfr does not have a change cycle for the fluid and I have verified the fluid clean. I did install a new battery and cleaned the ground on the terminal for the power steering pump as it seemed to help someone else. Mazda of course wants to take it and charge me to diagnose but based on other experiences with the dealer i do not trust them. Here is another person's similar story https://www.mazda3revolution.com/threads/power-steering-failure.108977/#post-1439705
