I believe the infamous oil filter TSB dates back well before 2011. That TSB scares so many people into buying only OE filters in the forums because how it is worded. The reality is, if someone posted about startup noise on any brand on this forum, most of us would suggest the oil filter as a potential cause... whether the car is a Hyundai, Ford, Chevrolet, or anything else. We all know a failed anti drainback valve can cause problems, particularly the nitrile rubber type found in most jobber or standard aftermarket filters. Quick lubes also are known to sometimes substitute the intended filter for another that they have in stock. A flat rate tech working a warranty claim quite frankly isn't going to spend the time to cross reference filter part numbers to make sure the right one was used or look at the different methods of construction to see if that might be the cause of an unusual noise. It is much easier to say that a known good filter should be used in this situation to see if it fixes the problem before going to more expensive and time consuming options.
What bothers me most is how some people interpret the TSB. I see this on other forums, and even from some dealers... they think the OE filter has a special valve that is missing in aftermarket filters. We all know that aftermarket filters include these whenever required. They also think that using an aftermarket filter automatically voids your warranty which is 100% untrue. Only damage caused by an aftermarket filter would cause the warranty to be void... a policy which every auto manufacturer has.
Actually started on the 2.0 Beta motor back in 2005.

USE OF AFTERMARKET ENGINE OIL FILTERS CAUSING ENGINE KNOCKING NOISE
DESCRIPTION:
Some vehicles may experience an engine knock noise with the use of an aftermarket oil filter. Aftermarket oil filters may use different materials, construction and specifications than genuine Hyundai oil filters, which may lead to pressure variations within the engine, thus contributing to an engine knocking noise.
VEHICLES AFFECTED:
All Models
REPAIR PROCEDURE:
Perform an oil change on the vehicle and replace the aftermarket oil filter with a genuine Hyundai oil filter.
WARRANTY INFORMATION:
Normal warranty procedures apply.
This is not a warranty repair.
Seems the PZ-37 has a problem,
had a similar issue on my sisters Santa Fe.
She is getting some TG filters on hers for a while (got a bunch of the TG3593a on clearance from Walmart).
