“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. …”
