    Video: I get this noise while steering at lower speeds. I also get random clicks or pops from underneath while driving straight. What I want to do here is rule out the possibility of a power steering/steering rack issue. Does this noise sound similar for that kind of issue? I do however have...

    Hello to my fellow ST owners, I got my 2014 ST3 about 8 months ago and when I bought it, it had a slight split in the dashboard right at the seam of the passenger airbag. After a while the seam started to grow larger and now I am slightly concerned for the airbag and my dash. Anyone got any...

    Car info: 2014 Focus St Relevant mods: Straight piped Cobb tuner (running on eco when it happened) tldr; Highway speed throttle did not respond to gas pedal. Restart “fixed” it. Not sure what to poke around with or just take it into a shop. So the other day I was out on the highway about 15...

    Hello everyone, I'm new to this forum and new to the ST platform. I was hoping with such a largo community here someone might be able to help me out with a little issue I’m having with my car. The issue I’m having is when driving the car and pushing the throttle down hard enough to start...

    So I had a problem on the highway. I was going about 80, went to accelerate a bit to pass someone (maybe about 10% throttle) and I felt my car jerk forward a bit and it wouldn’t accelerate anymore. It wouldn’t go past about 3k RPMs. It will go into gear just fine, it just CRAWLS and will not...

    I just bought a 2016 ford focus st. I am already having issues with it. It seems that my ECU can’t match the amount of boost i’m pushing. Very weird noise when I hit boost and my BOV isn’t going off correctly. The car when you let off the gas throws you forward kind of. I am running very rich...

    While maintaining throttle and between -3 and -1 vacuum, the BOV has started to consistently blow off 1 pound for a split second, every second so long as i'm between -3 and -1, roughly. It doesn't do this on higher vacuum, it also doesn't do this while under boost, to my knowledge (leaking). Is...
