I was driving home from work tonight, put gas in my 2017 Cruze Hatchback and about 5 miles later the check engine light came on and it was shifting rather hard on the highway between 60-70 mph. My assumption is the cold/low levels possibly of transmission fluid are to blame, but I'm here looking for advice.

Might I add that is also about -20 degrees here in Wisconsin as well right now. Haven't had any issues prior to this which this Cruze. Any ideas as for how I should proceed? Appreciate any help. Thanks.

I, unfortunately, don't have a scan tool. Guessing I won't get too far diagnosing it without that huh? It seems to be shifting okay anytime I was in the lower gears but up towards 60-70 mph is when it was struggling.

Being that you had just filled up, it possibly could be related to the gas you just put in.
Pretty much just guessing without the code.

Appreciate the feedback. I'll just have to pony up the cash and get the code at the very least. Thanks

One of the codes was

Barometric Pressure Circuit Range/Performance. [h=2]P2227[/h]
Basically, it's very cold out and the turbo is having a hard time overcoming that is what the mechanic told me. It's supposed to get back into the 30s and 40s the next couple of days so hoping that will be better on the vehicle.

Pay attention and address only the first code that is stored. Any following codes are generally a result of the primary code (#1)

The top code was P0299 engine underboost along with the P2227.

And sorry. It is not a diesel.

With my limited knowledge of car mechanics, do you guys think those codes are something that will fix themselves with warm weather coming in(going from -20 to 40 degrees tomorrow)?

How long would you wait before taking it back into the mechanic? Definitely can still feel the "no boost" in my car when getting up to higher speeds.

It may clear up once the weather warms.
It is not uncommon for frost to grow in the intercooler tubes.....especially if the car is being used for short trips.......this will affect turbo pressure as a obstruction.
There have been reports of PCV systems making frost as well.......I do not know what codes could come up if this was the case.

I would recommend not getting too excited till the weather is above freezing for a couple days.

Just an update if anyone is interested. Today the weather is about 25 degrees. A whopping 50 degree difference. I got a car wash and almost immediately after the car wash I had normal "boost" in my car. Almost positive stuff was just frozen with ice and couldn't perform.

I appreciate everyone's responses and learned a few things. Thank you
