heated cat not supported catalyst not ready evap system not ready egr not supported air system not supported air conditioner not supported

the car does not overheat, and the dealer tells us that the coolant needs flushed. i have replaced the heat actuator under the glovebox and it did not solve the problem. wondering if it the problem is in the actual heat controls in the dashboard? The car is under warranty but the dealer wants to run diagnostics which they are going to charge me for. so i decided to try and figure the problem out on my own.

I have rattlening noise coming from right side of vehicle. Chevy 1500 Silverado has two smaller convertors coming off right & left side of engine, then going into master catalytic convertor. Right side of my vehicle has non-manufacuture weld and part on left side of catalytic convertor. Any reported issue of catalytic convertor recalls for 2003 Chevy Truck Models

Where is the dip stick and is there a portal to add?

The car runs fine. I did have the oil checked and it was a quart or 2 low. The light is still on after filling up the oil. What is necessary?

The only way to get the car out of park and into drive is using the Shift Lock Release. What could the potential problem be?

The guy at autozone said it seems there is a blocked vacuum hose. The code says IMRC is stuck open -- probable cause is Short circuit, damage to the IMRC, or blocked vacuum hose. The check engine light is staying on.

The car only has 7000 miles on it. How can the brake pads be bad? How can rotors be bad? Can the rotors be machined but keep the pads if they are fine?
