Prius (Gen 3) :: 2011 DRCC Freezes Locking Onto Car / Hitting Brakes Even While No Vehicle Is Ahead
Jun 18, 2012
We’ve been running into a problem with the DRCC on our 2011 Model 5. In simple terms, the DRCC freezes locking onto car in front and activating the beeper/hitting the breaks even when no vehicle is ahead! So far, this has happened once to my wife (when she was making a 90 mile trip)
In all cases this has occurred as the car was passing a semi, when the front of the car was even with the semi drivers door. In one case, there was no car in front, just acted like there was one.
Whenever this occurs, the car continues to brake and the only immediate solution is to turn off the Radar. Also when we re-engage the DRCC, the unit is still frozen – braking for a non existent vehicle.
No problems turning the DRCC off and using the ordinary cruse. What seemed to “clear” the condition was pulling off the Interstate and turning off the car. I also noted that (after it had froze again) that when the ambient temperature had dropped below 90 degrees that the DRCC cleared. The first time my wife ran into this was hot too.
In summary, this has happened only when:
· Passing a semi
· Temperature is high (above 90).
I don’t believe that it is an alignment issue, as I’ve been amazed at how narrow the radar pattern seems to be (and very nicely tracks the steering).

My boyfriend ( a mechanic) has a 94 Lexus car for me to use how ever it has problems. It has rear brakes locking( they were changed) and the car freezes won't move in anyway. Every time when it's driven 3-4 miles it freezes steering locks in place won't move. What can be done?

When hitting the brakes, the 3rd tail light turns off and on in the middle portion of the reflector. The panel is removed from the inside of the car, as the truck has metal surrounding the top area.
How do you remove the 3rd tail light to check for loose connections or to replace the bulb? 2011 ES350...

I've generally gotten used to trusting the car to maintain distance and slow down autonomously with DRCC. However today I'm not sure I trust it completely.

On several occasions, with SKS fob in pocket, I have parked, turned off the car, opened the door, locked the doors with the interior door lock button (on the panel, not the physical door lock), exited the vehicle and closed the door, and then right about the time I make it to the rear of the car on my way to whatever store I'm going to, I hear the unlock "beep" and all the doors unlock.
Sometimes I'm more than a few steps away from the car. And sometimes I don't catch it, and come back to the car and find it's been unlocked all the time. It's like the SKS realizes I'm sitting in the car when I lock the doors, and maybe I'm too quick and it still thinks the fob is in the car when the door closes, so it unlocks the doors. But it's not the long "the-wife-stuck-her-purse-back-in-the-car-with-the-fob-again-even-though-she-knows-it-can't-lock" beep either, although maybe it's because it will let me lock the doors with a fob inside if a door is still open.

My daughter, after turning 16, has claimed our '07 with 170K as her own. Both my wife and daughter have been complaining that the car shudders when hitting the brakes.
For background, last fall, they heard a loud scraping noise coming from the front wheels, I decided that after 155K, it was time for a brake job. I pulled off the wheels and proceeded to swap the pads and rotors to discover that the scraping noise was coming from a rock caught between the hub and dust shield. Didn't really think about it prior to doing this, but this is a different beast when it comes to brakes and the pads still had plenty of life left on them. The piston on the right caliper refused to go back in to allow space for the new pads, so that needed to be replaced. Quite the frustrating job.
The brakes had been fine up until a month ago or so. I took it out for a test drive, but only detected a "shudder" when braking through about 20 mph. I didn't detect any pull in the brakes and the stopping power seems fine. They seem to experience something different than I do.
I plan on pulling the wheels off and having a closer look when our schedules allow. Is there anything in specific I should look for? The mechanical brakes kick in under 10 mph, correct? If the shuddering is happening above this speed, what in the regen braking system could cause this?

Relatively new Prius owner. I have a 2007 Touring model. I have two concerns I'm hoping some veterans can address for me.
1. I noticed last night that my left HID headlight turns off randomly (I saw it in the reflection of the car in front of me). I turned off the lights and turned them back on, and the headlight was working again for about 5 minutes before turning off again. This consistently happens so I'm pretty much driving with only one headlight on. The right headlight isn't having this problem, luckily.
Looks like Toyota had a settlement over the issue. I would post a link but since I'm a new users it's not allowing it.

I drive a 2006 Ford Escape Hybrid. For about three months now, sometimes when I brake the pedal only moves a couple of inches, freezes and the car won't stop. The car also makes a strange intermittent sound like someone humming with his mouth open. Sometimes the brake light comes on the dashboard, sometimes the ABS light, sometimes both, sometimes neither. When I take it in to the garage, everyone reports there is no code for them to read. During this time I have had the bearings (noticed road noise) and the brakes (squeaking) replaced in the rear right wheel.
Before the brakes were replaced, when the pedal froze, I stopped the car by pulling on the emergency brake, putting the car in neutral and/or turning the car off. When I restart the car, everything goes back to normal. Since the brakes were replaced, I haven't had to go to those extremes. I take my foot off the brake, depress it again, and the car usually stops. If the ABS/brake lights are on, I turn the car off and on again, and all goes back to normal. The problem could occur three times in a day or once in a month. I never know when it's going to happen. After reporting these symptoms to my local Ford dealership, the place where I buy my tires and my garage mechanic, they all shrugged and said they couldn't do anything. I'm thinking no one wants to be liable when the crash comes.

I have had my 2011 model III for a month, and today I had to brake rather abruptly. I heard my tires squeal! Is this normal? I have owned at least two other vehicles with ABS, and I recall the pulsing of the pedal, but not tire squeal.

Just recently bought a 2005 prius. It had a few issues that I have been addressing.
Last issue is that the steering wheel has a very slight bind/sticking in the straight ahead position. Very slight steering corrections needed when driving straight down the road are annoying because of this bind/sticking. Steering is smooth and bind free through the entire range of left to right travel, except for straight ahead (center).
Does the steering gear have oil or grease that is replaceable? If so, what id the procedure?

There's no beep or flashing parking lights when I lock my doors on my 2011 Prius 2 when using the remote or the door handle sensor. I still get the 2 beeps/light flashes when I unlock. The lock beep was working fine and then just stopped. The doors still lock fine with the remote or handle sensor, just no beep/flash.

I have a 2005 F250 & both front calipers are locking up. I have replaced the front pads, no change, my mechanic installed a new master cylinder. No lockup for about two weeks until today. Front calibers are locking up again.

I have a 1999 f250 super duty, that was wrecked a few months ago. I have put the truck back together with the mechanic. The front drivers side was wrecked. The power steering fluid tank was cracked and had to be replaced. Also had problems with a box behind the drivers headlight? I did hard wire it together and it fixed the problems i was having the the speedometer and the transmission not shifting correctly.
Everything is put back together now but I drove it today and the brakes locked down after driving it a few miles? Had to push the truck hard to get it back to my house, a mile or so. If i let off the gas it would come to a quick stop. It is ALL four brakes locking up. If it sits for awhile they unlock but will lock up again after driving. The truck is lifted and the ABS light has come on.
It was not on before but i am pretty sure the ABS is disabled on the truck. the wires are hanging down by each tire. This is how they truck was when i bought it. Not sure what is causing the brakes to lock up.

A couple months ago my VW Passat started locking itself and sounding the horn spontaneously, and now it is rolling down the windows randomly as well. My key isn't in the ignition when this happens. I got locked out once which was annoying, but now the windows rolling down make it a security issue and I really don't want the windows down in a parking lot during the next snowstorm. The heater quit working last week, too.
The car is only 2 years old and the dealership said they can fix the heater but they aren't sure what would be wrong with the spontaneous horn/window/locking problems.

I have a 2014 Prius Three with basic stereo (non-JBL). I'm trying to use a 64GB USB thumbdrive with about 5,000 mp3's grouped into different folders. Each folder has about 200 songs. Any song I play, doesn't matter which one, the headunit just stops playing on the middle of each song. What can I do to resolve this?

I just purchased a 2012 Prius Three. It has the touchscreen radio and whenever I use the USB port with either my iPod or USB drive the song would randomly freeze and would not play any other songs. When I switch source to Bluetooth it would just display loading. The FM and SAT would still work fine. If I listen to Bluetooth through phone it never locks up.

The release hatch in back of the 2010 thru 2015 Prius is horrible in the winter. It freezes and gets stuck causing the back hatch not to open. Maybe they should have had some kind of setup like the back window defroster where it defrosts the hatch...

2003 toyota Camry. when coming to a stop and hitting brakes there is a poping sound. It almost sounds like metal hitting each other. What is this or causing this!?!? Also it is a 4cylinder automatic with 100000miles.

Got a POP noise when I hit the brakes. I have to apply some pressure for it to make the sound. Does it once when going forward. Doesn't do it again until I drive a few minutes, then it does it again.
If I go back and forth between reverse and drive, it does it every time as I hit the brakes, but only once until reversing direction again.
Takes some moderate pedal pressure to make the noise. If I turn the steering wheel to either side, it doesn't make the noise.
I've gone over the brakes, nothing there is wrong, and besides it wouldn't go away when I turn the wheel. Nothing is loose in terms of tie-rod ends, wheel bearings, nothing.
It's not bad enough yet to be able to see movement in the ball joints when the wheels are off the ground. Is this the ball joints?
