When was your '09 put into service? March of -08 or later you'd still be in 5 year and your under the 60k.

Just missed warranty....

Yeah, it seems reasonable that if it is a 2009 it is still under the 5 year portion of the warranty, right? My car was built Feb. 13, 2008, and was first Placed In Service on March 14, 2008. I just missed the warranty period by a couple of days (the problem first occurred on March 16)!

The problem repeated itself on SIX tries to start or restart over a 2 hour period. On a good note, since I have changed the A/T fluid it has been flawless for about 20 starts/restarts over the past 2 days!

I will follow up with any problems I encounter, but for now, let's put this thread to bed and make the assumption that everything is now working properly unless I revive it. Thank you all for your contributions to this problem.

If I had that kind of trouble with my trany, I'd do at least one more dump. Couldn't cost more than $30 or so.

Make sure you are not parked on a hill. For whatever reason my transmison jumps and shudders "as close as I could call an auto grinding" when going from park to drive after having parked on a hill

I believe it has something to do with the parking gear itself Idont 100 percent understand the mechanics behind automatic transmissions but it has to do with the part that keeps your car from moving in park it seems hills stress this part highly,and wind up causing a gear grinding like affect.

I just don't park on an incline with the nose of the car higher than the rear bumper. It never happend with the rear bumper higher than the front.

The parking pawl can get jammed if you park on an incline without using the parking brake. Ideally when one parks on an incline, one should turn the wheels, towards the curb when facing downhill, away from the curb when facing uphill, and then engage the parking brake before shifting into Park. This will prevent the parking pawl from engaging and thus potentially getting jammed and if for some reason the parking brake fails, the vehicle will roll into the curb instead down the incline.

Follow up and problem determination.....

A few weeks after I changed the A/T fluid, and having been problem free the whole time, the problem started again, grinding in Park and Neutral. When I was getting ready to start the car, someone was talking to me from outside the car and I didn't turn the key all the way to start, but the starter started turning the engine over and it started. And again, the grinding noise. I turned the key quickly to start and released and the noise stopped.

The problem was in the key assembly. I took some electrical lubricant and sprayed it into the key hole, put the key in, and started and turned off the engine several times, to work the lubricant in.

So, once again, after several weeks of no problem, it appears that the problem has been fixed. The "grinding" was not in the A/T, but in the starter motor somehow being activated when in Park or Neutral.

I'm sure the dealer would have wanted to replace the whole key assembly at mucho $$$$$.

Glad to see you fixed the problem and that you came back here to give a resolution to your problem. So many posts have open threads here.

Ignition switch symtoms and fix

I have a 2008 Santa Fe and had to replace the ignition switch due to this issue. It was an easy job (if you do it correctly).

Symptoms of a bad ignition switch on these models are:

The starter will engage when you turn the key to "ON" (usually intermittently)
Starter will stay engaged after the engine has started (usually intermittently)
Starter will engage when you shift into "Park" and/or "Neutral" (usually intermittently)


Ignition switch replacement procedure for 2008 Santa Fe:

Tools needed - Phillips head screwdriver, flat head screwdriver, small ratchet w/ 10mm socket and extension (or a 10mm nut driver), flashlight (preferably with adjustable stand or an assistant to hold).

Disconnect the negative battery terminal (10mm)
Disconnect the positive battery terminal (10mm)
Insert the key into the ignition, turn to the "ON" position (leave it there until done - do not turn the key to another position with the ignition switch removed)
Remove the lower panel (4 phillips head screws - 2 visible on bottom and 2 under side flip panel in door jam)
Disconnect plugs from panel cluster and OBD II connection (all of these are easily disconnected with a medium size flat head screwdriver)
Remove inner panel (4 - 10mm bolts)
Disconnect large and small plug from ignition switch
Remove ignition switch (1 phillips head screw) (should slide out nice and easy)
Disconnect small plug harness from switch (medium flat head works well here too)
Inspect old and new switch to make sure they are exactly the same (also look at the center pin receiver to make sure it is not misaligned on the new switch)
Install using these instructions in reverse order.

The whole process should take the average person no more than an hour being very careful and not in a rush.

Hope this helps someone....

I had the same grinding noise coming from one of my 2009 Sonatas. After replacing the white ignition switch part, my problem was solved. I even got an extra ignition switch part incase my other Sonata later have the same problem.
Thanks to advise from people here, I was able to fix the problem myself saving hundreds of dollars!
