Question about 2006 Hyundai Sonata
I have replaced gasket o-ring on cap twice. Car will not leak for short period of time and then leak re-occurs. Is this a trademark of this model. Problem started when grease monkey oil change business
changed oil for $21.95. They supposedly didn't replace o-ring on filter cap. Now it leaks whenever it feels like it, even with napa's gasket kit.
I also continually have to change bulbs on brake lights. They last a couple of months, then go out, either side is not particular. I am using napa's heavy duty replacement bulbs,they still burn out with their higher amp suggestion.
I finally figured this out. I was putting the o-ring on incorrectly. I actually had two o-rings installed.
The o-ring should not be visible when it is tightened down. The plastic should be touching the metal housing. The o-ring sits inside the housing, right above the threads, but not at the top. Two pictures attached.

I had a service company change oil on my 2006 Sonata, V6.. The second oil change was done by an inexperienced worker. After a day, I saw oil residue on the ground and the engine. I discovered that the cap holding the filter was not sufficiently tightened. It needs to be more than hand tight for the average person, even with the O rings properly in place.
I have not experience the brake light issue you describe.

Same problem, 2500 miles on SantaFe 2009 oil leaking third filter. Looks like we may have recall. I used different filters, and if I tighten any more I will crack the cap. I will bring back to the dealer next week.
