Hey everyone I just had the break booster recall performed on the 2012 CX-9 with 75,000 miles. I was driving last week and suddenly lost break power, you'll know because your driving without power breaks and it requires you to put a lot of weight into the peddle. I was able to apply additional...

I was running late, so I started with some quick shifts and high revs right out of a cold start, then a stop and a quick u-turn. Within sixty seconds (right after the u-turn) I noticed that my acceleration had gone from peppy to pathetic. I drove about 40 miles and went from 1/2 a tank to 1/4...
