Unidentified motor noise coming from rear end while car is off

I can't answer your question specifically but I've also heard our Clarity making noises long after being shut off. Having owned two Prius cars that make a lot of clicking, buzzing, and motor noises I just ignored the Clarity.

 

BMS at work. What's the temperature in your garage?

 

My Volt makes crazy noises in the middle of the night. Nothing to worry about.

 

That's nothing compared to the sounds a Tesla makes while just sitting there being charged. I've lost track of how many different noises it can make.

 

Same with both Volts that made more sounds than a small content animal, just sitting there and plugged in.

I wish we could find evidence of any life at all after the Clarity fully charges and is still plugged in (still waiting to see if we get answer from Honda via the dealer).

 

I often hear the buzzes and clicks, but I also get chirped at when I open the trunk. Not sure what that's all about. I suspect it's some kind of alarm - but I don't know what it's for. However, at least twice now I've closed the trunk, but it didn't latch. No alarm then. Seems like if a door is ajar or a trunk isn't completely shut, the car shouldn't lock without an alarm - and that's what I thought the chirping was about whenever I go to get something out of the trunk after I've already shut off and parked the car. Anyone else have this happen? (not the absent-mindedness, lol, just the chirping after the car's turned off and you are emptying the trunk)

 

I have the car set to automatically lock when you walk away, but if you get out, close the driver's door then walk around and open the trunk the car will give three or four short chirps and then not lock anything when you close the trunk. I could be wrong about that last part but I'm pretty sure the auto lock doesn't auto lock after it chirps at you.

 

Interesting. I bet that's exactly what's happening. I'll have to check next time and see if the car relocks itself. I have mine set to auto-lock as well.

 

Yes, I too have gotten that alarm when I’ve parked the car in the garage and began walking away. Each time I’ve checked that no doors were ajar. They weren’t and nor have I opened the trunk. It doesn’t happen all the time, but it’s happened more than a couple of times.

 

This explains what happened to me today. I locked the car using the button on the handle. As I walked away, it beeped a few times. I thought I had accidentally left the engine on because that's what my Lexus used to do when I walked away with the car still on. So I went back to check and the car was already off. I had forgotten that I just enabled the auto-lock feature.

Once I got home, I only recall one beep as I walked away. Has anyone figured out what causes the car to beep multiple times versus just once?

 

I sure haven’t. It happened again yesterday, yet the doors were all closed and properly locked. Very strange.

Bringing the car in today for a rotational metallic sound that increases or decreases in frequency with speed. I suspect we picked up something that was rubbing against one wheel. I couldn’t see anything obvious, and the sound actually stopped late yesterday. We’ll still take it in to be safe.

 

I never thought of it that way, but you’re right. Pretty ironic.

My rotational noise hasn’t returned and the dealer saw nothing wrong after having it on a lift and a test drive.

 

As a follow up to the auto lock beeping as I don't think the question was answered. I believe when the vehicle is in auto lock, it should beep once when you close the door and are within 5 feet and then again once you are beyond 5 feet, which is signaling that the door is locked. Today, I noticed a change as I walk away and hear one long beep. I checked to make sure vehicle was off and all the doors are closed. I can't find anything in the manual that provides assistance. I manually locked the vehicle with the remote key.

 

Yes, with no explanation sometimes the auto-lock will not work. If I get the regular "multiple chirps" (my Nissan Altima would make a similar sound if I left my keys in the car and tried to lock it), I now know that the car will NOT auto-lock and I have to lock it by hitting the button.

I have NO explanation for why it doesn't auto-lock occasionally. Strange.

 

Yup, I’ve had the same issue. Just had it today.

 

Same issue here. I have auto locking set. About every 15-20 times I walk away from car, instead of one beep, I get beep-beep-beep-beep and doors do not auto lock. I open and close driver's door and then it works. (The driver's door was already closed tight.) Same thing happened once with passenger door, so I don't think it is the door sensor. On my list of things I hope a software upgrade will fix.

 

Close the door again and then it usually works
