Grinding noise after turning truck off - need help locating it

[theblet]

I don't think so, because I don't always hear it. However, I often am not waiting around to see if it happens every time.

I’m going to make it a point to wait, listen, and time it up

Is it consistant?

Not consistent. I actually haven't noticed the noise lately. Also, I can't seem to find the auto engage setting. Can you tell me where it is on the uconnect 8.4? Thanks

does it sound like an acuator
motor? i hear it all the time after i shut her down and pump gas comes on 2
or 3 minutes later coming
from underneath area near drivers side back tire, all normal
noise dont sweat it if this is what your hearing..

Mind does this. It's the rear brake engaging and disengaging. I thought it was odd, but to test the theory, I put the parking brake on when I pull into the garage. When I put the parking brake on, it doesn't do it ever (over the course of 2 weeks). When I started leaving the parking brake off, it started again. The noise has changed over time, which would be indicative that it's changing with the brake pad life.

That was my conclusion. My dealer had no clue.

It kind of sounds like that, which was my first theory

Sounds similar to mine. I thought we could turn off the “auto park brake” option but can’t seem to find it.

I believe it's under the "engine off options"

This is what the manual says,

Thanks I will look again.

again, electric park brake. It's not the auto park engage feature. Under certain circumstances, it engages automatically and when u crank up next time, it auto disengages.

never intentionally, but I’ve triggered it before

A friend had his truck backed into at a parking lot and broke the parking pawl. Shop that fixed the transmission told him if he’d set his parking brake there would’ve been no damage to the trans. He always sets his parking brake now. A parking pawl is very small for the amount of work it has to do.

Plus using the parking brake regularly keeps it in good working order for its other important job as the emergency brake. A brake pedal on the floor is not the time to find out it’s seized from lack of use and maintenance.

I wonder how to tell if the park break is engaged when I put it in park. Would the light be on ?

Yes. Both the "brake" light on the dash, and the LED on the switch.

I wonder if auto park brake is a/the reason for brake moan. Hard to avoid unless you service calipers every other week.

 

[theblet]

Yes. Both the "brake" light on the dash, and the LED on the switch.

Cool. I’ll see what it does when I put it in park today.

I have the auto option turned off, and it still does it

Just checked mine. When I put it in park, the e brake light does not light up. Tried it multiple times. Not sure if I don't have the feature, or it's just off. The only option I've seen in the uconnect screen is the brake when backing up with the door open. That one I have disabled.

Yep! An actuator that is protesting a little, maybe like a worn motor or it is being overworked with some resistance.

could just be the sound it makes. Haven’t had it happen in a few weeks.

e brake is off.

That's the brake making that sound? For some reason I thought it was like the fuel pump shutting off or something.

Right … Most agree that’s what it is, but many off us have turned the auto e-brake function “off” in Uconnect, and it still does it ….. Maybe Uconnect not turning it off correctly …. God knows it can’t save my stations presets for more than a month, so why would I think it could handle a brake function correctly …. Sorry, mini rant over …..

Ha. Yeah I turned off the e-brake after the first time it slammed my truck into park when backing into a parking spot and the sensors saw a shadow. Felt like my engine seized up.
