Chevrolet of Bend

Have only had our suv for 9 days. They said the 2011 suburban with only 80k miles went through inspection before we bought it. I found out through my mechanic that the breaks were bad and needed to be replaced also the oil cooler lines were leaking. They replaced only the break pads and said they would not replace the oil cooler lines doesn't really make sense to me. If something is leaking when it's inspected would t you fix it so the customer is super excited about there purchase of there new car. Super frustrated after spending 33k on a vehicle that's why I never buy a vehicle at a big dealer not trust worthy. I guess I learned my lesson
