Ice built up on intercooler?

I live in regina, SK, all the service advisor told me, after he check for, the codes, that the intercooler has ice buildup on it, and to replace it, he wrote down both code s for me, when I got home, I check out what those code mean, both of them were showing, number 2 oxygen sensor is bad, I never had that problem before with my car, most of the driving I do is city driving, the day before the car started acting up, I was out on the ring road, I maybe put 8 miles on the car, going from one dealer ship to the next one. It was not very cold that day, minus 15 Celsius. The car was running fine, my car is park outside all day, 2 days later when I went out to use it, the check engine light came on, right when I started it. It is solid, not flashing. In the city the car was running good, but I wanted to see if it would act up at highway speed. So once I got out on the highway, I went maybe about a mile, the car was running fine, all at once the power drop right down, it would go about 80 clicks only, I could tell it wasn't shifting properly, after about 5 minutes, when it started losing power, the dash monitor was showing, engine power is reduce, as soon as I could turn off from the direction I was going, to go back into the city, I drove about a mile and a half, then it started running like it should, when I got back into the city I went to put more gas in it, I filled it right up, then went to a restaurant, I was in there only for a half a hour, come back out, I wanted to take it out on the highway again, to see if it would keep running normally, in the city it was alright, the minute I get out on the highway again, it lost power, and the dash monitor was showing the same message again, the questions I have, is will they trough a code if there is a problem with the inter cooler, and also the turbo, or the transmission. I have been told it is a common problem with the Chevy Cruze intercoolers, icing up, I had it check again if any other codes have come up. Only the 2 from before showed up.

The only codes that are showing, have to do with, the number 2 oxygen sensor, my questions, were very simple, all I want to know is if there is ice buildup on the intercooler, or if there is a problem with it, if a check engine light code, will show up for it, and I was asking the same question about the turbo, if it went bad, if a code will show, for it, the reason I want to know about this, after the gm service advisor, check it to see what codes were showing, I as him what has to be done, he told me, there is ice buildup on the intercooler, and when that happens, they have to be replaced, of what I have seen, on the Cruze forum, that is only a problem, that occurs, with highway driving, witch I wasn't doing. At the time, also on the forum, it states that people had the intercooler replaced, and it did not resolve the problem.

Greg, yes ken, I am living in regina, Saskatchewan, we do get very cold spells here at times, but my understanding is, that it happens, with highway driving mostly, not with city driving, as I stated in my first post on here, last week, I was out on the ring road, but that day, we had normal temps, for here. I have had this car for a bit over 5 years now, and drove it out on the highway, in very cold weather, and never had a problem with it, until now.

I have been told buy one of the mechanics to go out and look to see if there is ice buildup on the intercooler. I took a flash light out with me, first I shone it though one of the opening on the upper grill to see if there was ice buildup showing on the air conditioner cooler, or frost on it, the is no ice on it or frost at all on it, or wet spots on it, it is completely dry. Just like it would look in the summer. Then I bent over, to shine the flashlight in the opening on the lower bumper cover acted like I expected, even before doing this. There was no ice buildup on it or frost, or wet spots on it also. Again, it looked like it would be in the summer time. The codes that show are p2277/ and p2099. As I said before, I checked what those codes are for, it shows in the code lookup manual I have, that that has to do with the number 2 oxygen sensor, that it went bad.

I finely look last night, there is no ice buildup or even frost buildup, or wet spots showing on it, . Ni new from before, there wouldn't be ice buildup. Because of not doing any highway driving, at all. My car exterior is kept very clean the inter cooler, transmission cooler and radiator still look like they did from day one. When the car was new, there isn't even any dust or dirt built up on that stuff. Also, I don't abuse my vehicle.
