My Sonata rolled over 10K on Friday so today was oil change and tire
rotation day. A few observations and comments:

1. The care has been very trouble-free during this time. I've really
only had one issue that required a visit to dealer (the noise in the
dash over sharp bumps), but that remains unresolved as I was unable to
reproduce it with the tech in the car. And it is less pronounced and
largely nonexistent in warm weather so I'll try again in January.

2. My overal fuel mileage is 29.30 MPG.

3. The front wheels were hard to remove, with the driver's side front
being very hard to remove. I had to beat on it for several minutes with
a hard polymer head hammer. I was about to get out my 5 lb. sledge when
it finally broke free. I've never had this problem with a car before.
I brushed grease on the flanges to avoid some of the rust in the future.
I've never had a car where the flange protruded so far through the
wheel hub hole.

4. Another first for me ... the oil filter gasket didn't come off with
the oil filter. I didn't notice this when I pulled off the filter as I
immediately turned it upside down and let it drain into the pan.
Fortunately, I always wipe the gasket flange with a paper towel before
installing the new filter. The old gasket came off with the paper
towel. I'm really glad it came off! I've changed my own oil for 30+
years using a wide range of filters, including early on the now infamous
Fram filters, and I've NEVER had this happen. Makes me question the
quality of Hyundai brand filters. The gasket is differently shaped than
most other filters and it appears to not be crimped in very well.
Anyone else have this happen?

5. The OEM Michelins appear to be wearing very fast. I typically get
60,000 miles given my driving style and regimen, but it appears that
nearly half the tread on the front tires is gone after only 10,000. The
wear is quite even so I don't suspect misalignment, but I suppose that
is possible.

I'm now ready for my second 10,000 miles, except I've got to check the
AC filter as that also calls for inspection/replacement at 10K as I recall.

I have had this happen to me one time in my life Matt. I don't remember
what type of filter it was though. I don't worry much about this kind of
thing though. If the gasket is doing its job there will be no leaks and
that's all that it is there for. If it does not come off with the filter,
then that does become something I have to watch for in changing the filter,
but not something that concerns me at all from a functionality standpoint.
I would not find this to be a quality concern.

I always wipe the flange so I should always catch this, but the fact
that the gasket comes off of the filter at removal is a quality issue to
me. The part isn't designed to do that, and anything it does that
violates the design intent is a part failure. And it greatly increases
the chance that a new filter will get put on top of an old gasket and
that will almost guarantee a serious oil leak. The hope then is that it
gets caught in time.

I agree it doesn't affect the functionality of the filter that lost the
gasket, but it may affect the functionality of the next filter if this
isn't discovered. It is a failure and thus a quality lapse. I'm
curious now to see how often this happens. If it happens again, I'll
switch to NAPA or another filter brand whose quality I trust. But I
have a whole case of Hyundai filters so that will be a while, lost
gaskets or not!

Matt, Glad you are enjoying the Sonata. Great fuel economy -- I
somewhat regreat not buying the inline four GLS. A thought about the
unsolved dash rattle you mention. I had a similar one that took some
time to locate. Mine sounded like it originated in the glovebox area.
Turns out it was the wood/black trim running across the dash (divides
the top and bottom colors). It was not properly seated (most likely
when an audio installer pulled the head unit to connect an amp). This
piece is accessed/removed with screws visible when the glovebox is
open.

I'm surprised to hear your Michelins are wearing quickly. Michelin
Energy tires are known to be fairly hard and long-lived. It's a good
idea to report it to your dealer and have them check the alignment.

These tires are rated high, but always wear fast. I can't find too many
people that managed to get the expected wear out of them. This is my third
car with them and I've had to replace them at between 20-25K miles on all.
Mind you, they were't worn out at that mileage, but once you hit 1/2 of the
tread life on just about any Michelin, you will notice a dramatic decrease
in traction, especially in the rain or snow.

Mine sounds like it is coming from the glovebox also so it may be the
same thing. I plan to have the dealer take a look at it again this
winter when it happens more repeatably.

Yes, I'm surprised also as I've had exceptional mileage in the past from
Michelins.
