Bad Oxygen Sensor at 14k miles

[Truckin1999]

Hey guys, I have an 06 GT with 14,000 miles. The oxygen sensor is bad already and I was wondering if its a common problem on these cars. I searched the site and didn't find anything to say it was but I figured I'd ask. The code just popped up after not driving the car for most of the winter. The first real drive this spring the light came on and I scanned it and got a P0134 Oxygen sensor no activity bank one sensor one. I've reset it a few times and it always comes right back. The car is still under warranty, but I hate letting anyone else touch my cars. Seeing as how the thing is like $200 I'm not paying to replace it. I figure I will set up an appointment and wait for them to fix it. I refuse to leave my car there and let them test drive it afterwords. I'm expecting to hear some *****ing about my mods saying they caused the issue. What do you guys think?

O2 sensor failures are rare at low mileage on the Vibe. They might rag you about the Magnaflow but obviously it has no influence on the first sensor.

not really, but I do remember Mavrik had his MAF replaced with very few miles on it.
