I purchased a 2018 Tacoma brand new last year it currently has 10k miles. I was driving and all of a sudden I couldn’t turn the steering wheel. I reached my destination lifted the hood and noticed the cap to the power steering reservoir had popped off and the fluid blew out everywhere all over the engine. I proceeded to fill it back up with fluid put cap back on and I took it to dealership and they don’t know what caused it. They finally told me that they are just gonna replace the pump and rack and pinion with all new parts. They did say that they found metal shavings in the fluid but still don’t know what that’s all about. Do y’all have any idea what would’ve caused the cap to blow off like that in the middle of driving and why the metal shavings? Obviously it’s under warranty and I will not be charged for repairs but my concern also is that this will be a slippery slope where issues will start happening all pointing back to this incident.
