I have a K&N in my 06 Yukon and no problems. I have used a K&N in my Grand Prix GTP for about 80,000 miles and have no problems. I have also used a K&N in my 01 Saturn SC2 for 225,000 miles and have not had a problem. The problems are usually caused by over oiling the filters after cleaning. Just make sure the filter is coated evenly but not dripping with oil. Only use the special K&N spray filter oil.
