Mueller Services / Mueller Reports review: I purchased a used car from this "reputable" dealership and 6 months later it turned out to be a lemon

I purchased a 2009 Rav4, on January 29 2025 from Muller Auto Group Highland Park, IL
I researched purchasing from a reputable dealership as I knew I was going to buy a preowned car and wanted to make sure I was buying a decent car.
I was shocked to find out that after being told that they had looked over the car and advised that it was all in good order except the brakes that would be needing to be replaced soon. I accepted that as it was preowned. What I could not accept is the $5,000 worth of additional repair work needed on the car just 6 months later.
I feel that there is no possible way that a car that was looked at by a reputable dealerships technicians' could have missed such tremendous issues as stated in one of the documents attached.

I included the document from the dealership of everything that was looked over and also the repair bill and what was included in the $5,000 repair
