Question edited into proper written English. Question moved to model category. Clean throttle body and MAF. If that doesn't work, you need an auto electrician with a pro grade scan tool computer to diagnose the electronics.

There's a small rubber pad which sits on the brake pedal arm, and holds the brake light switch OFF when the pedal is released. When this rubber pad falls off, the brake light switch is on all the time, not just when the pedal is pressed down. Find the rubber pad, and glue it back on, or make a replacement from cardboard, duct tape, whatever.

Most automatic transmissions have a separate belt for reverse and all forward gears, The reverse belt is commonly lighter duty that the forward belt (some Chryslers were affected so much it was advised to not shift into reverse until the engine had warmed up and the automatic choke idled down) Thus your car would be in "reverse" but with no motion getting to the gears.

usual on 4 cylinder around 175psi.225psi is very high for your car,150psi seems ok,you may have two problems.A leaking head gasket and high compression due to carbon build up on the pistons.Check your Hyundai Dealer to see is this problem is covered under their 100,000 mile warranty,it should be.IF not then
the head needs to come off and had gasket replaced along with clean the top of pistons since they are right there,sounds like and easy fix.also check condition of radiator,and I would rec. replacing thermostat since some Hyundai models had problems with their thermostats

Should be glued in with urethane.

Try to describe the sound as well as you can. Could it be an exhaust leak?

You shorted something out. Check all fuses and relays. I think you blew a relay not a fuse.

at the exhaust manifold there is a flex joint in the exhaust pipe what you describe indicates that that flex section has failed and need replacing There is no transmission problem

Hyundais have the tendancy to blow the ignition switch, yours was probabbly replaced, and by doing so you will need the Original key the car came with, not the new one included in the kit for the ignition switch.. also have you checked the little battery for the keyfob??? it probabbly went dry. best regards!

Remove the two screws holding the bracket to the back of the glove box and lower the bracket. Then remove the glove box and you can access the cabin air filter door

Vacuum leak is most likely candidate, but can also be a fuel pressure or injector problem. To test the sensor, the computer purposely commands a quick rich lean cycle to see how fast the sensors react. If injectors are dirty, pressure is off or there's a vacuum leak, it can screw up the response time.

Easy, find someone that has an OBD2 meter and get the error code # ( an example is Po256) Then plug the code number into google and it will tell you what is wrong. You have to have a sensor on the engine component for the ck engine lite to come on. Leaking fluid will usually not have a sensor, so this is not the engine light problem.

Check the power steering fluid

Check out all the wiring connections having anything to do with your transmission. Some wire has dislodged.

ask for a quality injector cleaner to be added to the tank ask that the fault codes be read as part of the service

Confirm ur fuel pump is working. Ensure ur pickup tube is not blocked. Then ensure u did not leave a rag or parts in the manifold tubes. Not laughing it happens. Is the distributor in the right spot. Etc etc. Did u rehook the alt up if removed . Is tje battery fully charged. And lastly is the fuel flowing and freash. Then recheck your work did u replace all parts right. Any air in the head gasket will make the fuel /air mixture off.
Good luck

I had same car different year and my transmission went for unknown reasons. I have also heard of others
