Front and middle crossmember rusted out to the point they have no more structural effects issues discovered while fixing a know issue to these models : rusted out and leaking engine and transmission oils pans I had confirmation from the dealership and other independent repair shop that leaking oils pans are common for those models and can cause engine and transmission failure. For the crossmembers they are important structural components that directly affect suspension/direction and drivetrain secureness. If the plastic shrouds/cover are not taken off during inspection those issues will gs undetected until one of them reaches failure
