I have 2016 CRV SE with 37000 miles. It has gotten regular oil changes at the dealership. Yesterday, I turned the car on and it started shaking and jerking while in reverse. The check engine light, VSA light, electric power steering light, oil light all turned on. I shut the car off and restarted it. The shaking stopped but all the lights turned on. I checked under the hood and the coolant and oil were low. The oil was about a quart low. I brought it to the dealership today and all 4 spark plugs were fouled. The 2 cyclinder was the worst. The dealership accused me of using bad gas. Has anyone run into this issue yet? I fear this may mean something much more serious is wrong with the vehicle. I asked the dealer to run a compression test and I am waiting for the results.

Bad gasoline certainly could cause the warning lights to come on as you observed. (Look at the SIMILAR THREADS at the bottom of the page.)

But we would need more details to answer your question. The 'rich' running at cold start could have made the plugs sooty looking but that would be normal.

What was the code that the CEL indicated?

Also, how long has it been since the dealewr's oil change? You should be doing an under-hood fluid check at least monthly.

At 37K miles there probably isn't any major issue.

I will ask the dealership for the code today. They said there was a misfire in cylinder 2. I will try upload photos of the spark plugs

The dealership said the code was P0302 that indicates that cylinder number 2 is experiencing misfires. ... A misfire from one or more cylinders can be caused by many reasons from a faulty ignition system, fuel system or internal engine failure.

So what is the dealer doing nto resolve the issue?

If you indeed have bad gas (contaminated with water from leaking tanks) they will drain the fuel and re-fill.

Years ago a certain brand locally had improperly mixed gasoline additives and they repaired many engines due to damage.

The dealership replaced all 4 spark plugs and did an oil change. Never mentioned draining the gas. The charged me $500 and said we found nothing wrong

:kaboom

$500 just for $75 worth of spark plugs and an hours' labor????????

Did they give you the old plugs (so you could provide a picture)?

At least, they confirmed my belief that there wasn't anything major wrong.

I took a picture of the spark plug from the 2 cylinder where the misfire happened.

Hard to tell with the shadow, but again doesn't look THAT bad. Gap might be wide. (Should be 1.1mm)

Electrodes otherwise look normal (white-ish color, not black as with rich running)

What do others think????

That should have been a warranty issue.

Edit:. Misread the year

Bad gas very possible.

As for the plugs, plugs are a warranty issue depending on your warranty (over 36000k may not cover it)

Now as for what's on the plug:

Oil, that's what's left behind when oil is burned off in combustion chamber. Yes it can and WILL fowl plugs.

Water in the gas mixed with everything will cause this ash build up as well

Now $500 for the dealer to do that, I probably would have been arrested for punching the service manager in the face.

Do you drive with the ECO button pushed ON a lot?

Misfire, low oil, low coolant....sounds like possible head gasket issue.

The OP asked the dealer to check compression, 'nothing found wrong'.

The unanswered question was "How long since the last dealer oil change"? If it was several thousand miles, those underhood items should have been caught by routine underhood checks from the owner.

Granted I've only owned my 2016 CRV for about a month (and only put 1300 miles on it) but I've had it on Eco the entire time; it suits my leisurely driving style.

Now you're implying that I'm damaging it?

The spark plug looks OLD. Electrode looks OK. I assume they are the original plugs?

After 4 new plus and oil change, and a nice profit for the dealer, it should run better. Fill it with quality gas and run it for a week or more.
If it doesn't run as it should, take it back as they haven't fixed the problem.

You cannot damage the engine by running in ECO. It's possible (but not likely) that short-trip use in ECO will require more frequent service. (There I go, advocating the 'Italian Tune-Up' again...) :Jestera:

Still, the OP's plugs should have been had plenty of life remaining @ 37K miles. Our '06 plugs were fine (even acceptably gapped!) when I changed them as maintenance at 115K miles. I DO run our engine to red-line once or twice a month!!!!:BigGrin:
