NHTSA Complaint #11517323 — 2012 CHEVROLET EQUINOX

I bought my 2012 chevy equinox Lt 2.4L because I owed one just like it but a deer totaled it at only 10 mph! It been nothing but issues since I purchased it drove it off the lot the check engine light comes on and then I go to get it checked and it states that I have a permanent catylic converter code that no one can fix except gmc! When I idle at a stop for longer than 1 min it starts stuttering and jerking like it’s gonna die! So I clean my throttle body like the mechanic said I should do and I found this dark brown whitish sludge in my pvc tube that runs up into the air box which now my air box is full of this gunk! I have to put oil into this vehicle every 3 days cause it will be full then three days later it’s just a smidge above out on the dipstick! I am poor I can not afford huge repairs or replacement of yet another vehicle 🚗! GMC needs held accountable since they seem to know about this and it’s not recalled they need to do better in taking care of us poor customers who just want a reliable vehicle!! So VERY upset yet again!!!
