T5i Err 02

[Rknea]

I recently purchased a used T5i and Pro Master 64GB SDXC card at a local camera shop.  I took 20-40 shots in the shop and it worked great.  I got to a Big Band show, took 2 pics and received the Err 02.  I reformatted and reinserted the card and still had issues.  Back to the camera store the next day and of course it wouldn't give the error.  They replaced the SDXC card with a new one.  I upgraded the firmware to 1.1.5 and for 2 weeks (about 55 pics) didn't have an issue.  Today as I was taking some pics, the error pops up again! I absolutely love the camera and quality of pics and videos I've been able to take, but this error is a pain!

Other than "take the camera back"...are there any other suggestions?

True...all things will eventually fail...if this were a shutter or mechanical issue I'd agree but this feels like more of a software/interop issue than hardware failure IMHO.  I have been in contact with the camera store twice and since the most recent failure was yesterday, I'm going to be reaching out to them this morning.  I'm sure they would take it back for a full refund...they're a very reputible place of business!

Well I purchased a 32GB SanDisk SD card and so far so good!  I'm really hoping that this is the solution!  Fortunately Idaho Camera said they will refund the $$ I paid for the ProMaster card as well.  Thanks everyone for your input and suggestions!

Merry Christmas!
