Hello everyone, I bought a 2014 civic si august 12th. I test drove the car and checked it over and everything seemed great. I got the car about 75 miles from where I live. On the way home I needed to get gas so I stopped and put 20 of premium gas in and 15 minutes later the car went into Limp mode with all the systems lights flashing like Tpms, auto hill start, power steering etc. I can disconnect the battery cable and the car will reset and drive normal again for awhile then right back into limp mode. I took it to get the codes scanned and it shows that it is misfiring on all cylinders. I've taken it to a Honda dealer close by and they seem to think after a week of having the car that I've gotten bad gas because the pulled samples and said it didnt smell or look right, so they are draining the gas, cleaning the tank and gonna refill with good gas and see if it happens again. Does anyone have any idea if this could be the cause or have experience with a situation like this.
