Prius (2010-12) :: Alarm Went Off While Driving
Jun 1, 2010
After buying my Prius III, the dealer installed a Karr alarm system which has a blue LED light underneath the steering wheel which blinks when it's armed and, if the alarm goes off, blinks once to three times to tell you what set off the alarm.
Tonight I was at dinner and afterward entered my car using the SKS. When I started driving the car I noticed that the LED was blinking making me think my alarm had gone off. After the alarm was first installed, the installer showed me how to reset the LED by holding or clicking the button behind it (I didn't remember how exactly) so I tried pushing and holding the button but nothing worked and it kept blinking.
I continued to drive home and all of a sudden my alarm started going off while I was driving. I pulled over, turned off the engine, and with the key fob locked and unlocked the car. I started driving again and would hear intermittent honks before the alarm went off again for 20 seconds before it stopped on its own.
Finally when I got home I again turned off the engine, locked and unlocked the car, and the blinking LED finally went away. As I was walking around the car inspecting it to see if it had been hit to start all of this in the first place, the car beeped and locked itself automatically as if I held the door handle for the SKS or pushed the lock button on the key fob. I unlocked the car, tried to recreate it, and everything went back to normal.

I have a 2006 with 155k miles. I took it into the dealer for a mini service this week. Drove home after the service was complete, then drove to work yesterday. On the way home an alarm sounded and the red triangle light with !, the break system light (O) with !, the VSC light and the engine CHECK light came on.
A friend used his scanner to read the error code for me and it reported a "p0a80" code. What does this code mean? Replace the hybrid battery?

I have the 2010 Prius with 23K on the dial and over the past few days when going to use the vehicle, at the time of applying the brake pedal and pressing start, all fine, then when we attempt to move the shift leaver to D or R we are greeted with a continuous audible alarm and the display, is telling us to shift to Park with a few other words for Parking the vehicle. No other warning lights occur but we found out the car will drive or reverse with the continuous alarm and message displayed for selecting P.
Okay, put techstream on and I have no trouble codes, at all in fact which is a good thing and I can also hear the car working as normal with P engagement, neutral etc. So the only way to correct the alarm is to turn it off and try again. Any try many times indeed! So its happened to the wife and now myself. Eventually for some reason all back to normal. I've also tried variations of brake pedal application and trying to move vehicle thinking P pin locking problem but it appears to be a signal malfunction or something simple.

Twice this week I have received the Yellow Triangle alarm with the message Key Battery Low. This is the first time I have seen this alarm since I bought the car in August 2009.
I changed the battery the first time after 3 years based on recommendations from the forum. This time the batteries lasted just over 2 years.
I tested the batteries on both Key Fobs and they were both in the 2.9V range. The new batteries tested at 3.3V which is their rating. So ~2.9V must be the low alarm setpoint.

Just had new tire installed and now noticing that the original stem cap was not used. Alarm is not lit, but wondering if I should try to retrieve the original one, since we notified the tire shop that afternoon......or purchase a new one.

Once I was driving down the street, stopped at a red light, and then the alarm just started going off! I sat there and looked around for a couple of seconds and realized that it was my car. I figured out hitting the panic button turned it off. Happened again the next day, but not since. Whats up with that?!

Still getting used to my 'new to me' 2011 Prius II. I am loving the car it's a joy to drive, very smooth and quiet.
When I pull the car out of the garage it's obvious when the ICE starts. But after that I never am aware of the starter being used at all.
Is it just road noise that prevents me from hearing it? Or is it like a manual transmission car that you restart by letting out the clutch once it's rolling?

2 months ago while driving both headlights (low) went out. Had to drive with my high beams on to get back to the house. Next day they worked again. 2 days ago both low lights went out again. My son checked and the bulbs are fine, the fuses are fine but the voltage meter says very low voltage with high resistance. What does that mean? I know there was a class action suit for the same reason for up to the 2009 model.

I was driving 71-72 on an interstate with a 70 mph limit. In the distance, on a bridge I saw a bunch of police cars. Suddenly the Prius started beeping. No alarms went off on the MFD.
Within seconds of the Prius beeping, I saw a cop crouched on the side of the highway pointing his radar gun right at the car. As soon as I passed the cop, the beeping stopped.

2010 Prius III. Purchased at 75,000 miles now at 135,000 miles.
At all different speeds I'm getting a vibration. It used to be much more slight. But in the the past few months it has gotten progressively worse. I have read many other threads about it happening at near idle speeds but haven't found any previous topics concerning my dilemma.
But it happens when I'm trying to accelerate. Not hard acceleration but rather moderate or less. If I take my foot off the accelerator and reapply it it stops. I don't know what to think considering how different the problem is compared to descriptions of the mr2 acting funny.

I was driving through the Appalachian range in WV last weekend. During an upslope, I could hear the car dragging, the noise that we hear when we go on a steep slope. But even after I reached a plateau, I had a hard time going above 65. The more gas I pressed, the car never went above 65. The noise was still evident. After a few times, I switched to Normal mode (from ECO), and it marginally seemed to improve but not completely ok. For about 120 miles of Appalachia, I had this thing happen. Is this normal? I thought newer cars, especially on a plateau should not have this much loss of power.
I am going to get my 5000 mile service today, and anything obvious I could bring it to the dealer.

When I first got my generation III, I had it on Eco. I found this hard to adjust to after being in a Camry. So I got the car out of Eco mode, but didn't put it in either EV or Power mode. I've been assuming this is OK for over 35,000 miles now. Is there something wrong in what I'm doing?

Last night I was driving my '99 Passat when suddenly I heard this loud alarm in my car. Quickly looking down I saw what I think were my ABS and brake indicator lights on. It happened so fast, maybe less than a second and everything was back to normal.
I was driving on dry pavement on country roads at about 60 mph. Outside temp was 37 and there were major gusts of wind, maybe 40 mph or so. Vehicle has about 115,000 miles on it.
Checked my manual and it said to have it checked.

A few nights ago while driving my 2010 Prius III on the highway I suddenly heard a whistling sound, as if my window was cracked open. It was not, and I guessed that there was some other piece of the car that had come loose (similar to a previous incident with my splash guard under the bumper and I just popped it back into place and re-secured the pin).

During a recent vacation, while driving at night, the MPH display went black. I completed the drive to the hotel, resolving to change the fuse in the morning. When I started the car in the morning, the display was still black. I checked the fuse I thought should be involved (#22), but it was good. The MPG / MPG screen was still bad. Not wanting to drive an additional 400 miles back home without a speedometer, I called the closest dealership to get an appointment. The 2010 has 33K miles on it .
When we packed up and started the car for the trip to the dealer, everything was working. One week later and all is good. I plan on getting this anomaly recorded with Toyota just in case it happens again after the warrantee runs out.

I've never had a car before where rolling the window down put in so much gale force wind into the car. I used to be able to drive with windows down (not on freeway and sometimes even on freeways) quite comfortably but now it is just too much wind blowing into the car.

2012 Prius V w/24k miles. Have experienced a noise while driving. (best I can describe it is like when moving a straw up and down through the lid on a styrofoam cup). It is intermittent. Have discussed this with the dealer service department at least three times. One tech drove with me said he found a bad front strut which was replaced. It took some time but noise returned. I can hear it when others can't and can feel it through the floor board. It may be muted but also so loud my wife says it sounds like something is going to fall off. Does it at slow speeds across parking lots on smooth surfaces or on road on smooth and rough surfaces in any kind of weather conditions. Will be taking it in for 25k service soon but what to look for.
