Prius (2010-12) :: Servo / Motor Noise Under The Bonnet When Unlocking Door
Oct 4, 2012
Whenever my Prius has been at rest for a while, such as sitting overnight, and I come out in the morning for my drive to work, as soon as I grab the handle and the door unlocks there is a distinct sound like a motor/servo/positioner under the bonnet that runs for about 3 to 4 seconds.
I am curious as to what this is. It's 100% consistent, so it appears the car is prepping something in anticipation of starting the hybrid system - part of the "pre-flight prep" procedure perhaps?

I've had my 2014 Prius II for about a month now and am really happy with the car. I do however have a question. Every time I go the garage and open the driver's door to get in the car, I hear a servo-like noise under the hood lasting for a few seconds. probably 5-6.

I have a new to me 2010 Prius. What I'm trying to do (I did it with my 2008 Prius) is to be able to unlock any door from the outside as long as I have my fob in my pocket. I've tried following the directions in the manual but to no avail. I've tried holding lock and unlock on the fob simultaneously for 5 seconds, all doors open shows up on the control panel, but when I approach any door except the drivers door, nothing happens.

Having issues with the rear tailgate door unlocking. Seems like mine on occasion is only making a noise but not unlocking completely and showing the door ajar light with the beep. When it happens, its a pain to get it to stop and close completely, or even open. I have to push hard on the door to get it to stop.

After the car is parked for a while, when you open the driver side door or just touch the door handle an electric motor starts running. After several seconds it stops. Sounds as though it is running a pump and building pressure or vacuum. Just wondering exactly what it is?

My FOB is only unlocking my door. It's not locking doors. Thought it might be the FOB battery. I changed it and still no locking, just unlocking.

I'm having a problem with my remote lock/alarm system in my 2010 Corolla LE. The driver door suddenly stopped locking and unlocking with the remote. The other 3 doors work fine, but the driver door won't work. When I lock the driver door with the key and press the lock button, everything locks and unlocks like normal. If I wait awhile and try to unlock the doors again, the driver door lock again won't work.

The fob of my 2006 prius stopped unlocking the driver's door, it does unlock, however, all other doors. Also when locking the car all doors lock no problem, so the weird thing is the "unlocking of the driver door" that doesn't work unless I use the little key inside the fob. I already changed the battery in the fob and it is still doing the same thing.

I just purchased a 2012 Prius. I tried to program the all doors are unlocked when the driver's door is opened within 10 seconds after turning the Power switch off. On page 89 of the user manual, it explained how to do it but me and my dealer could get it to work.

The SKS on my 2010 Prius V used to open all doors when I grabbed the door handle but now it only opens the driver's door. I remember seeing somewhere in this forum that this is one of the few driver customizable options (unless it is for Gen II only) and I should be able to make the change on my own.

This afternoon my Gen II Prius started smoking from under the bonnet, and a strong electrical smell is present. The car does not start into "READY" mode. I am having it towed to the local dealer right now.

Just walked by the back end of my new Prius III and heard what sounded like a electric motor running from the general area of the exhaust pipe at the right rear end of the car. This was about 5 hours after I last drove it.

When I get near the driver's door on my 2008 Prius in attempt to unlock the door, nothing happens. However, when I get near the passenger door or the rear hatch, they will both open but the car chirps 5 times. The driver's door remains locked. It's not the battery in the key FOB, because if it was, no doors would open unless I remove the key from the FOB and physically open the door the "traditional" way.

I got the car running again, so no need to go into details on that (I used the physical key on the keyfob, you really do have to turn it further than you'd think, but that got me into the car, after several tries was able to get it to stop cycling through the locking/unlocking and was able to jump it).
Got the 12v battery in my Prius replaced by the dealership in the last 2 years. Last winter, one day my Prius refused to start even though it had been running fine earlier that day and was parked in a semi-heated garage. Jumped it and got it working.
Last Friday I went to get out of my car and my Prius kept beeping at my any time I had the door open, and the clock on the dash seemed to be a little dim. I doubled checked that the keyfob was in my pocket (and not in the holder thingy), eventually the car seemed to lock fine and I went up to my apartment. Didn't drive the car until this morning.
This morning I come down to find that keyless entry does not work, nor does pressing the unlock button on the keyfob. (The car is parked in heated underground parking fyi.) About every 1 second on repeat, the car is making this sound like it makes when you hit the lock/unlock button from the inside of the car, so it seemed like it was stuck in an endless loop of locking or unlocking. I go back upstairs, leave my key fob in my apartment (which is around 300 meters away or so), come back down - it's still on the loop making that sound.
I get into the car with the physical door key, try starting it - the lights will come on but the car doesn't seem to actually start. And the endless lock/unlock loop starts up against once I turn the car "off". I got upstairs and switch to my other backup keyfob. Come back down. Car is still in the endless loop. Try to start it again, car still doesn't seem to start, but this time when I turn it "off" the endless lock/unlock cycle finally stops. Do finally get it running by jumping the battery, then it seems to run fine.
So I bring it to the dealer, and the guy their rather vehemently insist there must be something wrong with my keyfob. First he immediately confidently assures me that I just need to replace the battery in the keyfob, which makes no sense. Then he changes to saying he thinks the lock button on the keyfob was stuck down, which doesn't make sense either as like I said it continued doing it even when I removed any keyfob from being anywhere near the car.

My Prius just reached 200000 km this week. I bought it at 180000 km 2 years ago, I don't drive it that much simply because I work from home.
Today, a sunny day, 0 degrees, the check engine just lit-up. I opened the hood and checked fluid levels, all OK. I started it and listened to the engine, running as usual. However, when the motor stopped (hybrid ON), I can hear a high frequency noise. I don't remember hearing this noise, but I don't think I ever opened the hood with the engine Off but powered On.
How can I get the check engine code ? I assume I need a connector, right ?

How to go about turning off the signal flash when unlocking the vehicle? I grab the door and the signal flashes twice indicating unlocked, I do not like announcing to my neighbours every time I unlocked my car. My dealership tells me they do not know how? I was hoping there is a series of buttons to press or something like that. I have a 2012 base model (one).

The noise seems routine. It happens when you get close to the car and open your door. I guess the car is anticipating that you will start the car soon and under the hood, some subtle mechanical noises occur. Just wondering what that noise is?

I bought my prius about a month ago and noticed something odd about the door sensor recently. I would place my thumb over the groove of the door handle and hear the beeping noise, but the door is still locked. Placing my thumb again with another beep would open the door. When I first got the car, I only had to do it once.

Today was the second time I have walked into the garage and heard my Prius making a weird noise. It's not the noise that comes from the front when you open the door or press the brakes....It's coming from the rear of the car. It stops when I press the start button. I made a video of the noise (nothing to see, as it was dark in the garage, but you can hear the noise.
My concern is that it's something running that will wear down my battery if I happen to not notice it is doing it sometime in the future.

I just recently noticed that when I come to my car and on my key fob, i press the unlock button only once, the only door it unlocks is the drivers door, the other 3 remain locked. Only when double clicking the unlock button does it unlock all 4 doors. Is this how its suppose to work?
