IS 500 Parking issue (Shift **** jitter back to P)
Greetings,
My beloved IS 500 is showing unusual behavior that is really concerning me. I already had a very bad day on Thursday and Friday. Please bear with me for the full story.
Yesterday night (Saturday) it was a bit colder around 35F around 9PM, and my IS 500 did not see use for say 3-4 days (before this my car was not even used for more than 40 days and it was all fine). So I went to my garage, pushed the start button, the Redline was all the way up to 3K RPM as-usual. And I put it in Reverse from P. There was a very very very loud thud as if something hit. Usually when I start the vehicle I wait for 2-5 minutes. This time I was in urgency and immediately put in Reverse... Now after coming out of the driveway, I engaged D and then stopped for a while as I had to speak with someone and then put it in P then the Shift **** was jittering back to P as if it was not engaged to P properly. My car did not even pass that 615miles breakthrough mark. It was around 475miles when this happened.
After I drove like 15-20miles to a nearby Motel I did not notice that jittering. Now again today it is doing, it is not related to how long I drive or how fast I drive or which mode it is in. As I tried everything including applying brakes, revving to 5K RPM in S+ and doing Manual up/downshifts and it still happens.
One thing I would mention is sometimes when I engage the P to R there is a slight clunk, my guess when it happens is when we leave the Brake a bit early. Did I miss that brake period and screwed up something ? But that means the car is too weak, as it cannot even handle a bit of brake force difference, as I never experienced such with any cars I drove from rentals to etc. Is our shift **** system brittle as it operates by cable ?
The Parking Brake below the steering on the right side works by engaging although it disengages if we press the throttle in D / R modes (I suppose that's how it works)
Here's the video (Gdrive link) of that in action that I recorded. I'm really pissed off & very sad at this.
Any comments / thoughts please.

Regarding the loud thud, that's usually caused by the electronic emergency brake that has engaged and then not used in a while. Sometimes if I wash the car and then park it, the next day there will be a loud thud where the emergency brakes sort of get stuck due to slight corrosion on the disks. It's all fine afterwards and I experience this every time I wash the car and then park it with the emergency brakes on auto. I haven't noticed anything regarding the shifter jittering though.
Try setting the emergency brake so it doesn't automatically set and see what happens as you drive off.
If you shifted into reverse while the car was at 3k RPM you definitely could have damaged something. Automatic transmissions don't handle that well.
I think he meant he was idle and the redline was at 3k RPM, not he was traveling at 3k RPM and shifted into R. Lol if the car even lets you do that that would send you through the windshield.
The important question is, who were you meeting at the motel????

Well I read your post about 3 times and watched your video and don't see any issue. You put it in P and the shift **** was jittering back to P? I don't even know what that statement means. Transmissions naturally make clunking noises when you shift from P to N to D to R to N to R to P to D to P or whatever you did.
I'm filing this one under "nothing burger." There are a lot of those around these forums.
EDIT: Ok I think I see what youre saying. It makes a clunking noise when you go between P and R. Yeah that's normal. Is this like your first car?

Now that makes sense, the EPB system is the one causing that loud sound (whirring) as per the manual. But this time the sound was way too loud, exponentially very high pitch sound. Since I got the vehicle, the EPB mode is in Automatic from what I can understand through the manual. I will now disable that "EPB Shift Interlock Function" mode and see how it works.

Will try to do it, the Gauge Cluster is free of anything no warnings or such.

I think you may have overlooked it, please see the Shift **** at the end of 40 secs mark, when It put it from R to P, it jitters back to P and makes a slight sound. This was never observed with the ownership of the vehicle or even when I was doing a test drive.

Is your complaint about a sound, the shifter moving, or both? I'm super confused. Automatic transmissions do have a parking pawl that stops the car from moving when in park. If the pawl is not aligned it will "jitter" or clunk trying to slip in.
After reading all of this I'm surprised you haven't taken it in to the dealership yet.

Yesterday was Sunday so he couldn't. Dealership and service is open today on MLK though. I know bc this day 2 years ago I was the first one to get the CEL/exhaust fixed.
I think I've experienced this a handful of times on my prior ISes I've owned, but I didn't pay any attention to it. I don't believe I've had it happen on the IS 500 yet. Or, maybe I have. I always assumed this was normal.

I’ve never seen the RPMs as low as 3K on a cold start. Think that would freak me out. 😜
I believe the lowest I've seen is 3,500, but I do park in a garage that, while not heated, is attached to the house and is always warmer than outside in the winter.

Shifter moving back to P again even if it was on P, not the sound itself. I understand going to P makes a sound due to the pawl. Since It started having this new shifter movement backwards after that extremely loud clunk.
We had winter storm, I'm going to wait out until the snow is cleared out as its all rock salt and what not on the roads want to avoid driving the IS 500 for now. Once it is all clear, Ill stop by the dealership. And before doing that I will try to engage and disengage that EPB Automatic mode.
