The reason the car won't restart is due to the Check Engine light. You cannot remote start if there is a code triggering the Check Engine light. It started the first time because the code had not been triggered. The code must have set during the first 4 minutes while it was running. Only way to start the car in this situation is to manually start it by the button on the dash. It is a failsafe feature. GM doesn't want the car running for 20 minutes unattended with the check engine light on. That amount of time can mean the difference between a cheap repair or a new engine!

As far as gas getting into the oil.... Sounds funny to me, but I'm not there looking at your car. The obvious first step would be for them to data log fuel trims and 02 sensor readings during cold start, but that would actually require them to do their job. Good luck with that.

Thanks for that explanation, makes total sense.
They looked at the car today, no codes no problems. If nothing else I got a free oil change at about 2200 miles..........Just wait for the next big drop in temp and see if it happens again.

Came across this thread from Google, while i don't have a camaro i do have an ats with what i believe is the same 2.0T engine.

Interestingly I am also in Alberta and after the last cold spell i had the check engline light come on and it was throwing a p0172 code.

I also checked the oil and noticed it was above max and smelled of gas. I got the oil changed and cleared the code. Approx 3 weeks later the CEL returned, same code, che led the oil and it was above max and smelled of gasoline. This time I was 110% sure it wasn't overfilled.

I took it to the dealer last thursday, the service advisor isn't giving up much info- he even denies there is gas in the oil. They do have a new high pressure fuel pump on order.

I'll update further when I actually go to pick it up as the dealer is approx 5 hours away.

At this point I wonder if it is due to the very cold winter we've been having.. but just wanted to let you know, for me, at least, the problem did return after a few weeks from changing the oil.

Geez, 5 hours from the nearest dealer is rough. I would encourage you to post this on cadillacforums.com as well. There is quite an active community there, and a much deeper technical knowledge base. Please keep us updated. If the HPFP is failing, I really want to know. I don't want to deal with the same BS issues I had with my 2008 BMW 335i. This would be one of the first GM 2.0t HPFP's I've heard of failing.

Thought I'd add to this post. Had this CEL come on a couple days ago on my 2016 2.0t. Goes into dealership on Friday to see what's going on. Will update once they take a look.

When i took mine to the dealer they replaced the high pressure fuel pump, and changed the oil. A couple of weeks later (today) CEL is back. Same code.

Please let me know how yours goes, and i'll do the same when i get it in next weekend.

Anyone notice how all these issues are transpiring in Canada

[Tankman]

Our 2 Camaro's have not experienced this since! But winter 'ain't over yet!

[ymmbob]

As of now my best guess is idling the car in extreme cold causing the oil to become diluted with fuel. It lines up with everyone here being from Canada.. and the initial remote start question. Myself, I am guilty of idling it for 18 mins every morning in -40.

This time around I just got the oil changed and the CEL went out by itself. I won't idle it anymore and see if that makes a difference. I just ordered a new code reader that supports live data so I can keep an eye on fuel trims and get a better idea of when it's actually running rich and by how much. According to the service log, it was running at -8% live and on the freeze frame when the CEL lit it was at -30%.

[Evil-Bee-NH]

That's a good theory but I've done this not in -40 yet mind you but a few times in -10 maybe -15 with wind chill factored in.

Has anyone had success diagnosing this issue yet? just had this engine code pop up when i was driving on the highway the other day, and would like to know what has/ hasnt worked.

Geez... Another Canadian Camaro with the same issue. Hopefully your fellow countryman return to update their situations or possible resolutions! I'm starting to think there might be a difference in the Canadian fuel. Maybe a different additive that we don't use down here in Freedomland.

Wind chill has no effect on your car. All wind chill means is how the cold air *feels* to a person! So if it's -10, and -20 with wind chill, your car only knows it's -10, because it doesn't have *feelings*...

Gotcha you must spy on me using google earth to know my car doesn't have feelings. I think this issue is something in canada not the camaros themselves i mean chicago gets damn cold as well with that lake effect. Worse I've had is a -24 morning last year where it took a little to turnover but did start the first try.
