Prius (2004-09) :: Front Parking Sensors Don't Turn Off
Nov 15, 2015
I have a 2007 Prius 90'000km with new 12V battery from last year. The problem I have is that the front parking sensors won't turn off when I park my car close to an object and shut the engine off. This fully drain my battery and I have to jump start the car everytime I switch it on. The technician from Toyota repair shop couldn't fix it and proposed to switch the front parking sensors off by unplugging the switch under the wheel. That didn't fix the problem at all since it didn't deactivate the front parking sensor but only deactivated the switch.

So I've seen a lot of people on here wrapping the mid section of the front bumper black to give it a more aggressive look.
For those that have done this, will I need to cut a hole for the sensors or will the sensors still work with the wrap covering them?

I have a 2008 LS. The buzzer for my front parking assist sensors is significantly louder than when the buzzer sounds for the rear sensors. I have adjusted the buzzer volume to the loudest position (#5), but the volume of the buzzer when the rear sensors activate is still much lower than for the front sensors.
The indicators on the nav screen for all the sensors are working properly. Do you find the volume is different between the front and rear sensors or do I have a problem?
I am asking because I inadvertently backed out of a driveway into a car that was parked directly across the street. I do not recall hearing the sensor sound before I hit the other car. At the time, my sensor volume was set on #3. When I checked, I could barely hear the buzzer from the rear sensors, but could clearly hear the buzzer from the front sensors. Resetting the buzzer volume to #5 has worked a bit, but I still wish the buzzer for the rear was louder.

My front right (passenger) side parking light is broken and I can't figure out how to change the bulb. The left (driver) one is a simple twist and done, but the right one is just impossible.

Every time I park the car there is a weird electrical noise that comes from the front. Is this normal?

My left driver side parking light is out.
Can you get to that light to replace it easily, without removing bumper, etc??
And if so, what kind of bulb does it take??

I live in the Cleveland area and we got pelted with snow yesterday. For the most part, the car did great. Great traction and visibility while driving on low lit roads...It was only 28 degrees so it threw the warning for black ice which caught me off guard lol.
Then as I'm going to stop I hear beep beep beep beep beep!!!!
The parking sensors start saying there's something in front of me within inches....yet there's nothing within 50 feet. Every time I went under 10mph it kept doing this...well I got home and see that a small layer of snow was covering the sensors. Granted I can turn off the beeping and such but in a place like Cleveland there's usually a ton of snow and I can see this getting annoying really fast. This is my third car with parking sensors and the only one to react to a tiny layer of snow....

What speakers do the Parking Sensors use? Do they have their own?
If you replace the radio head unit with an Aftermarket one, do you lose the Parking Sensor beeps....?

At first the passenger side front parking light would randomly not turn on until you gave the light assembly a hard tap. Now I am having the same problem with the driver side low beam light. I checked the harness connector and it clicks firmly into place. So, I am guessing there's something not grounded properly somewhere on the light assembly. I'm hoping that a light film of dielectric grease will work but I can't tell where to put it.

I wonder, how will we know if/when the parking assist sensors stop working? Will the display be missing some of the yellow lights or will we have to find out the hard way?

When I put the gear on reverse, parking sensors beep even there is nothing behind the car! I tried to clean the surface by my finger!
The Last time that they worked pretty well was before I unplug and plug the power cable of my stereo system while battery cables were connected!
Can the problem coming from for that? How can I take the sensors out and clean them fully? Do you think disconnecting the battery for one minute can work?

I am owner of brand new Golf Sportsvan 1.4 92kw petrol, 6 speed manual. Since day two ive been noticeing that something might be wrong with my car. Second day of ownership i was greeted by TPMS, ESC, Auto hold and Stop start system error all at once, and parking sensors were beeping and button was flashing. Ive been reading about it and its not new for MK7 owners as i can understand. But what worries me most is the revs when the engine is cold and i start it up first time. Did a video and uploaded it. [URL] .....
Weird thing is i only get errors when its cold start, i mean for example yesterday and today it was cold here (-5 degrees celcsius) and car started up with no errors, but the revs where bouncing up and down like seen on video. Sometimes i get those 4 errors aswell and rev problem, sometimes only rev problem, but when the engine is at the working temperature i get no errors, no shakey revs.
Otherwise love the car. Solid build quality, Spacious, Like the pyramid gold color, lovely car, beside those gremlins.

How is it possible that the 350 F-Sport can track cars that are possibly coming at you while you're backing up, but it can't alert you to when you're getting close to a wall or other car that is stationary (aka parking senors).. Although I did back into a space yesterday and got no beeps as the car got closer to the other cars in the camera.
Another thing is having radar assist cruise control and no front parking assist... what's up with this craziness? The systems are actually installed in the car, but not able to beep at you?!

About 2 months ago my Touareg was rear-ended. I just got it back from the body shop and am finding little things that are not the same and I am wondering if they just need reprogramming or if these could be a bigger issue (going back to the body shop today)?
1. They replaced the entire liftgate, but the rear wiper is not working even though the washer fluid does.
2. The interior lights are on, even though all doors are shut, when the switch is set to the open door setting.
3. There is no beep when I lock my vehicle with the keyfob, but the lights blink.
4. There are no warning beeps for the parking sensors, even though the dash lights up.

I hear water sloshing around in the front when I make a turn. I am wondering the vent holes by the windshield wipes near the windshield are used to vent air intake into the cabin. Could this sloshing be coming from in there? Is there a drain hole and it f so where Is it located can I clear it? 2004 prius .....

80% of the time my parking sensors are always on, like something is behind the truck. 20% of the time they work just fine.
I replaced all 4 sensors today with ones off ebay and I get the same thing.
Anything else I can try before I have to take it to the dealer?
The originals and my new ones all clicked when I put my ear up to them.

The dealer tells me my batteries in my low tire sensors are bad. The low tire light on the dash won't go out. So I need to replace the TPMS sensors in my '06 type 5 Prius. I know I can pick them online much cheaper than at the dealer. My question is, is there some reprogramming that will need to be done. I'm assuming it will be some convoluted sequence with buttons on the dash similar to turning off the backup alarm, etc.

Today the parking brake light didn't turn off when I released the parking brake. Other than the light staying on, nothing else unusual occurred. I did not notice any indication that the brakes were dragging. The brake fluid level was near maximum.
After reading earlier Priuschat posts on this subject, I found the cause which apparently is explained in technical service bulletin TSB BR002-07 (Parking Brake Light Won't Go Out | PriusChat)
Here's what happened to me. For some reason, the entire switch body loosened from the firewall and moved away far enough away from the lever arm such that it couldn't contact the switch and close it when the pedal was released. I think it happened because I pressed the pedal too quickly and with too much force somehow. The switch is at the top of the pedal assembly and it's not too difficult to reach
So, I pushed the switch back against the lever arm and presto, the brake light turned off as it's supposed to. I tried the parking brake several times and it is fixed for now. Now I need to determine how to tighten the switch so it won't move again.

My work truck that I drive, a 2006 F-150 Lariat 4x4 extended cab, rear parking sensors quit working. The button on the dash is lit up all the time like when you shut it off. I posted this on the F-150 section too and was able to find a suggestion that you can listen to each sensor while in reverse and if you don't hear a clicking at the sensor it has failed. All (4) sensors are clicking away while in reverse so not sure what else to check, no one in the F150 section, so that is why I put it here.
