Please verify the ODBII code.
Looking at Hyundai codes it is not listed and online there are OBDII P0052 codes, but no P052 codes.
P0052 refers to a heated Oxygen sensor, bank 2 sensor 1 problem.
Only trouble is your engine only has Bank 1 sensor 1 and Bank 1 sensor 2 which would cause P0030 and P0036 codes unless the code is a Hyundai specific OBDII code
Here's an image showing the location of the two sensors in your vehicle, just in case it is a loose or fractured wire connection to the sensor(s).
