When turning the engine off in Neutral, the automatic transmission blocked, not letting me change to P. I unlocked it by pressing the button and the brake at the same time. I was then not able to remove the key. Why did this happen?

A full repair was made to my car's automatic transmission but, since then, I've been noticing that, after driving for a while, especially when it is along an inclined road, the second gear is suddenly put and it cannot be changed. In order to make it work properly again, it is needed to stop the vehicle completely and only then continue driving without the problem. I have also taken the turbo to be checked and have been informed that it is a bit distorted so it needs to be either repaired or replaced. How much time do you think my turbo can still work? Is it better to repair or replace it? In case it has something to do, the car has not lost its power. Thank you!

I own a Santa Fe 2010, engine v6 3.5 fuel, and when starting it in the morning or after 10 hours of being stopped, the engine makes a continuous "clip clap" noise. After three minutes of warming the engine, the noise disappears. I was told there must be a failure in the camshaft, what do you think about it? Is it something else?

Check engine on due to cam sensor

The Diagnostic results from auto zone states that ALL cylinders are misfiring. I replaced the spark plugs, wires, & coil packs all within the past 6-8 months ago. I have recently noticed a small amount of engine oil inside the spark plugs compartment. I was told it sojnds like the intake Manifold gaskets & rings. Will that fix the issue of it running poorly? Any help is greatly appreciated.
