2015 GMC Terrain body problems

STRUCTURE:BODY

2015 gmc terrain sle awd. Suv was taking in for oil change found excessive rust on frame under all four doors. On both sides rust and holes near the front of both rear wheels. I believe its called the "rocker" I'm unsure. I bought the car at a little over 71,000 miles in 2022-2023 now just getting to 94,000 in February 2026. If there was rust which there probably was the car should have not been sold if the rust was enough to cause problem later on. I may need to go purchase a new car while still owe some money in the car loan. Rust and hole in the rear control arm. The amount to replace and repair all the parts with labor exceeds current value.

First occurrence in September 2015. Rear lift gate acted abnormally, when I was parked,y son opened the lift gate using the normal door handle button, it raised, but as he was loading it lowered onto him. He is small, I had to get out and pull it off of him, it went up and down a couple times and then closed. You cannot stop it from closing down on you if you are trying to load or unload into that compartment. We have had to stop using altogether.
