Here is my old thread on this car:

So wife has a 2010 chevy equinox w/79k miles on it. Its been a good little car. It had the HPFP replaced a while back by the dealership. No other big issues. It does use a little oil here and there but Its maybe a qt in 7k. Nothing huge.
Wife drove it to CO for a spartan race and said she checked the oil when she got there(I told her too on trips). When she got home she said it sounded funny but still ran ok. On the way to work yesterday it was running rough. She said it about stalled out on her. I told her it was probably bad gas and to add some iso heat to the tank which she did. She calls me after work and now there is a CEL and a "reduced power" warning in the dash. She ended up leaving it at work.
This morning after I get off shift I go look at it. Start it up and its running rough, whining and knocking. I shut it off and check the oil. Nothing. I ended up adding 2 1/2 qts (holds 5) and it came up to half on the dip stick. I started it again and it sounded better but was still rough. No leaks found. Just a small weep on the bottom of the motor/trans.
So off to the parents to grab the car hauler. Got it loaded and ran it home. I called my buddy who works at a dealership in missoula and he talked to a tech. Said there is a oil consumption issue with that motor and I need to take it into the local dealership. I dropped it off and they called me a couple days ago. They covered everything under the oil consumption TSB and the timing chain TSB. New pistons, rings, timing chains and a bunch of other parts.
We just picked it up today and its crazy how much quieter it is. I noticed it was louder but never realized how loud it was. So now we have to figure out if we are going to keep it or sell it...
Its crazy how just a short bit ago I had asked about issues and then all the sudden they hit. Im Just glad we didn't have to eat this one..
