NHTSA Complaint #11482709 — 2011 CHEVROLET EQUINOX

I purchased a 2011 Chevy Equinox LT from a used car dealer in April 2022 with 153,000 miles on it. The second day I had it the brake caliper completely fell off of my front passenger tire causing my wheels to lock. Couple days later I noticed that after an extended time of driving anything more than 10-15 minutes it. The RPMs would fluctuate sometimes dropping down to zero and the vehicle stalls. The excessive amount of oil used in this vehicle is ridiculous I literally got an oil change and a week later it said I was low but my oil notification on my Dash messages said oil life remaining 95% check engine light comes on and it's the p0042 for catalyst system not at threshold. This literally should be a class action lawsuit because this is ridiculous
