O2 sensor issue with CEL code

I had my CEL come on and had autozone check it. they said it was the Bank 1 Sensor 1 O2 Sensor, or the MAF Sensor or an Injector. So I bought a MAF sensor Cleaning Spray and took it to it on the MAF sensor. that removed the code for 3 months. Then my CEL came on again and this time I check the code myself when the autozone guy read it. and it read that it was the B1S1 O2 sensor nothing else. No MAF or Injector code strictly O2 sensor. So since AutoZone doesn't carry the 5 pin O2 sensor for the XD2 GLS Elantras I when to the Hyundai Dealer and spend the ungodly amount of $179 for a new one. that's non returnable once you install it. the CEL immediately comes back on once I installed the new sensor and cleared the codes. So while I'm having my tires changed at a service garage the mechanic reads the code and says that its the B1S2 O2 sensor failure with misfire.
so I get a scanner of my own and this is what I currently have. P0038 & P0136.
code P0038 = Heated Oxygen Sensor Heater Control Circuit High (Bank 1, Sensor 2)
code P0136 = Oxygen Sensor Circuit/Heater (Bank 1, Sensor 2)
So my question is, is it really possible for both O2 sensors to go bad back to back or is this a programmed failure in the ECU? has anyone else had these codes? it just seams odd that right on the mark at 80,000 miles both o2 sensors fail.

This next question is off topic but have any of you guys used or know of some one who has used one of the Universal pillar gauge pods either from glowshift or elsewhere instead of buying the costly one from compactdivisions?
