While driving, my engine light came on. After taking it in, it turned out that I had water/oil freezing in the intercooler. This could have been very dangerous when I was driving. I have had the GM Wrap put on it. I am hoping that this will not be a problem again.
turbo/superchargers malfunctioned, and I had to have it replaced back up sensors do not work properly. Say backup, assistant, malfunction.
I bought the equinox with 30,000 miles on it. It's at 67,000 now and I maintain the vehicle regularly. So why have I replaced the throttle body already because it gets dirty fast? And now I'm getting a check engine light for P2099 TurboCharger Underboost. When the vehicle is not old it's 5 years old, hasn't been driven hard. So why are you using a crap 1.5L engine with a turbo that is notorious for these issues??? And what's worse the engineering is horse s$*t, because the air inlet hose is only one time use. But the part is underneath it where you can't reach. Why has this not been recalled yet????????? It's not but a scam to make you take it to a dealership. I'll continue to write complaints this is not right. And I'll never buy one again.

Dealer got an extra $3k for me calling GM to complain and I “saved” or got $800 benefit from GM cost assist. What a scam.dealer refused to give me paperwork showing the details of repairs or breakdown of cost. I received a receipt that stated engine replacement $9072.

They additionally said they aren’t required to provide me with any details regarding the GM cost assist or pricing.
