Hi! I drive a 2022 Honda Insight touring edition and recently I was having a flashing check engine light and shaking (which I later found out to be a misfire on cylinder 3) it would go away if I turned the car off and back on after about 5-15 minutes later. It came back two other times very intermittently and was told by dealer unless they can reproduce it then they can’t fix it and would charge me $200 to scan. Very expensive.
I pulled the code today when it popped up and it showed cylinder 3 and I was wondering if that’s a common issue and if it could just be a coil pack going bad? I have swapped coil pack 2 and 3 and am planning to see if I can pull the code again once it pops up to see if it’s changed but now I got a bunch of lights popping up on the dash for my power steering, adaptive CC, ABS, Lane assist and other electronic features.
I’m at a loss on what else could possibly be wrong unless, once again, it’s just a coil pack.

Common? Not really. Honda's wiring is very tasty. You might check if mice have been chewing on the engine harness first. Also as a side note, your dealer is a d*ck.
I did all I could to figure out the issue whether it’s a coil pack, spark plugs, etc. but it’s gone past what I could do with my limited mechanic experience.
The wiring harness had rodent tape on it but there was a scrape that looked like it came from a tool cutting the material rather than a rodent but I doubt they would believe that. Hopefully the repair doesn’t destroy me too bad.

Your post reminded me of a Shell gas station review I saw when I was hunting for cheap gas in the Summer. The review saved me from filling up at that gas station. Perhaps you've bad gas in the tank from a poorly maintained gas station?

If it follows the coil pack, you'll definitely know. Step 2 would be a plug swap between cylinders, I guess. Anything beyond that is going to get a little more difficult.

if it is a 2022 shouldn't this be covered under warranty?
Yes, but the way the dealership works is that... If they can't replicate the problem, Honda doesn't reimburse the dealership for labor during the diagnostic hence why they're asking for $200 as insurance. @AMysteriousGuy just needs to be sure it's a manufacture defect with the vehicle and not something like rodent or bad gas. The diagnostic fee would be cover by warranty for manufacture defect.

The other things @AMysteriousGuy can do is complain to Honda directly that his dealership is charging him $200 to scan his vehicle for misfire. Or try another nearby Honda dealership for help.

I’ve honestly thought that too but I go to a speedway and I don’t know if they have that kind of reputation from doing something like that but this issue seems to come from something more than just some bad fuel.

I'm not saying it's intentional but the systems in place to prevent it from happening is highly dependent on the employees. Gas stations use a monitoring system to alert them when it detects water in the tank. Also the filters on the gas pumps need to be change frequently which is another defense against water and debris from entering your tank. If the employees ignore changing the filters and the warning system alerting them to water then you have customers pumping bad gas. It can happen at the name brand stations and not just mom & pop gas stations due to careless employees.

Wow! I didn’t think it was this frequent at all! I guess tomorrow I’ll see what the diagnosis is. I’ll post it in this forum as an update so maybe someone facing the same issue can use this.

It happens more frequent than most people expect. The ground tank is protected by a cover and gasket. If the cover isn't latched tight enough or the gasket fails, water from rain will enter. I've seen enough news report about this over the years that I always get a receipt after filling up. You'll need the date & time as proof to file a claim with the gas station's insurance.
