Our 2017 CRV will not start. The battery in it is the original factory battery. About a month ago, we had the dash lights light up and all the system errors. Wife brought it to a shop that was doing her wheel alignment and he diagnosed that it was because the battery was dying. I didn’t believe it at first because the CRV didn’t sound like it had signs of a dying battery by listening to the motor crank over at startup. So we ignored it. Now we are unable to start it. It does the vibrating brake pedal thing like you described as well as random electrical issues and key fob problems. Did you get a new battery yet? Or are you still jump boosting it?When our 2018 decided to do the same thing you're talking about (a year and a half ago or so) and the brake pedal did weird stuff (sorta "vibrated" etc) when I went to start it, and it wouldn't start, I hooked up my "battery jumper" and started it. It started and ran OK but did that the next time. I read up on it and saw that it was the battery, which the car came with brand new, that caused it to do this crazy crap. I replaced the battery myself and have not had a problem since then. You'd think that a warning about the battery/charging system would've come up on the dash. I've since heard of this happening to other CR-Vs. As a result, I have two of those jumpers (I got a refund on the first one and was told to keep it, because the cheapie clamps were all plastic except for the "jaw" on one of the sides of the clamp, the wire going to that metal "jaw" and the spring/axle that held the two halves together - the plastic clamps crumbled and were useless, hence the refund and being told to keep it, but I digress). I bought a new jumper and put all metal clamps on the "old" one. So, that's why I have two... OH, and I recharge them whenever they get below about 50%..
