The fuel pump failed on my Tundra. Several dashboard check engine lights suddenly lit up to warn me of the issue. While I was able to safely get it to a mechanic to repair the independent Toyota certified mechanic I use shared they have seen a volume of these where the car stops immediately with the Fuel pump failing completely. I was lucky as the day prior to this I was driving through mountain passes on the highway in Colorado. I have since found out from the feedback from my mechanic that they have repaired a volume of these, and it is a known issue by Toyota who issued a technical service bulletin.

My power steering gear blew its seal on the passenger side losing all power steering fluid and almost making me crash into a car next to me, and Toyota refuses to cover it stating that I hadn't had the steering gear replaced prior to whenever their dates were this is clearly faulty equipment and faulty machine work on the steering gear itself. why won't Toyota cover it? I tried contacting One Toyota and Downtown Toyota here in Oakland California and they told me that they wanted $250 to inspect my vehicle and that I would definitely have to pay for it because my vehicle was not under recall it states it is a recall if you look it up.It is worded recall if they're not going to cover it sounds like they're trying to back out of covering it until someone gets seriously hurt or killed like I almost did, I will never buy another Toyota again as long as I live because clearly they don't care …
