2015 Honda Fit: misfire or rough idle

Filed Jul 2, 2023 · Electrical, Fuel system · WA

Before I parked, all was fine and the car felt safe, two hours later, I start the car and it has four warning lights on. Now I don't have Hill Start Assist and the car feels like it might 'go out' on me, I think something will keep it from running soon. About two weeks prior, even with keys in the car and with a full battery in both the keys and car, the car doesn't start with the first push of the 'engine start' button (maybe there is a connection here). O'Reilly helped me check the codes, and it states that I should replace the Ignition Coil, as well as the Throttle Body and it is giving the code, P0303: Cylinder 3 Misfire Detected. After some research online, it seems like the Fuel Injectors might need to be replaced as the ones that come with Honda tend to malfunction. Perhaps the TSBs (www.truedelta.com/Honda-Fit-tsbs-99,2015) should be put into consideration. I believe this is what has caused the Hill Start Assist to stop working which further makes me feel like the vehicle is unsafe to drive for me and for others. We are both put at risk because I am not sure what will happen with it next. I live where there are a lot of hills, Hill Start Assist was a huge factor as to why I thought this car would be safe to drive here. I have yet to visit a Dealer or Independent Service Center. The Vehicle has been inspected by O'Reilly's Code Scanner only and myself. In the attached pictures, one is showing the warning lights that now come on at the start of the car, and the other is showing about a minute later how another light turns on.

A couple of days ago I went to turn my car on, while stationary the dashboard lights lit up out of nowhere.the TPMS sensor began flashing, the check engine light came on, along with the eps & vsa lights. The car just got to 68k miles. I went to get my car scanned and the result was a misfire on cylinder 4. After doing more research, I found that many other cars (of this exact model) had this same issue & have been recalled, but mine hasn't. I'm worried it may become a bigger issue to my safety.

My vehicle began running roughly and all the dash lights came on. I was told there is a misfire in one of the cylinders and this could be an extremely expensive repair. My vehicle has 48000 miles on it and this shouldn't happen. From doing some online research, this seems to be a recurring complaint by several people.
