Get a diagnostic done by another mechanic, because clearly something is wrong and this person is unable to identify the problem.

Taking out the battery pole does nothing with the ECU. (Just as taking out the battery pole does nothing to the odometer) To effectively and effeciently remove all codes, a clear or rest needs to be done on the ODB or ODBII through a diagnostics. Usually the computer would ask if you're sure you want to erase all codes (even if none is generated). The reason why the computer u used said its all clear is because its probably outdated.

I used 3 different computers already and only 2 of them said the same exact codes and all 3 were different models. 1 listed 4 error codes and the other 2 listed only 2.

yeh its a 2005 model i have, never really had to change much parts other than the usual tune up part, and theyre pretty accesible. Body wise there parts available in the bamboo, i have the number for a place in the bamboo also that deals strictly with hyundai vehicles, so ur more or less good to go.
