Lexus LS 2007+ :: Continued Acceleration When Brakes Applied?
Feb 2, 2014
While driving recently I experienced what felt like continued acceleration when I applied the brake. It was only a fleeting moment, but was scary nonetheless.

View 6 RepliesI just purchased a used 2007 Lexus GS 350 AWD. I had it inspected and there were some minor problems (air filter, small oil issue) but nothing big. Driving it, I've noticed that the wheel shakes a little bit when applying brakes and based on my google searches, it's likely a rotor problem. I've literally only driven the car less than 100 miles since it was inspected. Does the inspection place (Tires Plus) bear any responsibility for clearing the inspection on the car? Should I take the car to Tires Plus to look at or should I take it somewhere else?
View 11 RepliesI have a 2007 Chevy HHR. A couple of weeks ago I had to change the caliper on the driver's side of the car. I had some squeaking after, but bled the brakes and the squeaking went away. The other day I took the caliper off and painted it. I have custom wheels and you can see the caliper plainly, it was rusted so I painted it. Now I am getting the squeaking again, but it stops when I apply the brakes. I bled them again, but still the squeaking. This is driving me crazy. Could it be the "chirper" that is dragging on the rotor? Also I want to add, it squeaks until I get up to about 45 mph. Then it stops. And as I said, it stops when I apply the brakes.
View 6 RepliesI just purchased a 2012 GX Ultra! So in the contract from the Toyota dealer (where we purchased the truck from) offered a 36 day "warranty" which says they will cover any problem that we experience from time of purchase to the 36 day mark.
The vehicle came to us clean, one owner, and the Lexus warranty for the 4 yr OR 80,000 KM just ended. The warranty just reached the 4 yr mark and has only 78,000 KM. Firstly we we called Lexus Canada to try to get info on extended warranty or as they call it "ECP". They said the local dealer usually does provide the warranty in a short time frame after expiration like this.
Secondly we are experiencing a sort of rumble when the brakes are applied. We felt this rumble on the test drive, and told the sales person we wanted this fixed before we drove off the lot. When we did leave it still had the rumble. Now we might think it is a mechanism within the car to alert the driver the brakes are being applied.

I recently bought a 2007 Sonata V6, and the brakes pulsate (when applied) at highway speeds, so I am looking to replace the front rotors & pads. I have been told that the OEM rotors/pads aren't great & that as a result many owners have a brake pulsating/vibration issue.
View 9 RepliesMy '07 GS350 recently began exhibiting brake squeal when brakes were gently applied. I subsequently took it to my dealer for a multipoint inspection, with the results being the car was fine, including the brakes. I was told the squeak was the result of brake dust, and nothing to worry about.
Since the inspection, I noticed the right front wheel is accumulating brake dust, but none of the others are; and the noise is irritating. I called my SA yesterday and explained the situation. He reviewed the car's service history, and noted the front pads were replaced with noiseless/dustless pads 40k miles ago. I agreed. He again said it was nothing to worry about. My thoughts are I'll have to put new pads on the front, even though the current ones are fine.
I'm looking at buying a 2006 GS300 AWD with 91K miles for 18K. My husband noticed when you touch on the brakes they vibrate/chatter..? The previous owner took very good care of it and I believe it is all hwy miles. The part that is weird to us after looking over the car fax, we noticed from 2006 to present it has been in the shop anywhere from 2000 to 5000 miles getting new brakes, pads, tires fixed, rotations, tires fixed etc.. Does this year have problems with the brake system? Has there been a recall on the brake system? I'm finding 2006 has other problems but I can't find anything on the brakes. Also, when you look at the menu for service on the nav screen the brakes and oil are red lite...?

When apply brakes the front end shimmies until car completely stopped then go again & all is well until at some future time it happens again. Dealer checked twice & private repair checked also. Nothing found. Tires re-balanced & rotated several times. Newer tires with no issues. This is an INTERMITTENT problem. The rotors have been, new pads & spring installed.

I discovered that the brakes are not releasing quickly after application. Examples where this has been noticed:
When braking and accelerating at the same time to dry brakes after puddles. Noticeable lack of power to re-accelerate when you release the brake pedal, presumably due to continued braking. Noticeable continuation of braking when trailbraking into a corner (ok sometimes I'm a bit of a racer in a family car).
What concerns me is when the snow, ice or heavy rain comes back that I might find sudden instability if the brakes aren't releasing after slowing for a corner or that worse still I'm destined for total brake servo failure.
There are no ABS related error codes although in the ice and snow I did find that the ABS fired until the pedal raised stiff and all 4 wheels just locked up (that was a fun junction crossing).
I have noticed that the drainage ducts in the bulkhead are blocked but I've never had water enter the car so I don't think it's water in the brake servo although this could have happened prior to me owning it I guess.
Working theories:
Due to slave cylinder corrosion and calipers are releasing slowly
Due to brake servo fault - either water ingress of vacuum leak
Just today AC started blowing air rapidly from the vents when I didn't have the AC on. The AC continued to run even after I had turned off the engine and took out the key. In fear of my battery dying I unplugged it but as soon as I plugged it back in to drive home from work it was the same thing. Where should I start?!
View 4 RepliesAfter putting my Ford Ranger in park and pressing down on the E-break to get the news-paper or mail. I've noticed that there is a consistent squeaking coming from the back drum brakes when the brake pedal is applied. But only for a certain period of time; then the squeaking stops.
View 8 RepliesYesterday, my SC430 started screeching and the VSC lights came on. I had never heard this alarm before -- sort of between a whistle and a screech. I was a few blocks from home, so I continued on. I did not notice if the ABS light was on at this time, but I don't think it was, because I would have noticed an unusual light on the dash.
I disconnected the battery briefly, but not 3 minutes, and the alarm continued when I switched the car on. This morning, I disconnected the battery again, this time for more than 3 minutes. Again, the alarm screeched when I started the car and pulled out of the garage. I switched it off, and then back on, and the alarm stopped. I thought I had solved the problem. I was wrong.
Later this morning, I drove to the bank, and when I took it out of drive after visiting the ATM, the alarm started again. It continued until I got home. This time, the ABS light is on, in addition to the VSC lights.
On the way to the bank, I made one fairly hard stop at a yellow light, but I have made far harder stops without any lights -- and especially annoying alarms -- coming on.
None of the posts I have found here mention this alarm when the ABS light is discussed.
I have checked the brake fluid level, and it was full. The car was in a Toyota dealership last month for its 120,000-mile timing belt, and the rear brake shoes and rotors were replaced then.
I have yet to begin checking the fuses, but I don't really think this is the problem. Before I try bridging the post in the computer terminal, I plan to visit the local auto-parts store that will read the computer for trouble codes.
I lost a brake line on my pickup truck, had it replaced a couple days ago. Occasionally, when i apply the brakes i get a brake chatter. It has occurred 3-4 times in the last 4-5 days. No pattern to it happening.
View 4 RepliesMy dad purchased a new 2013 Nissan Frontier 4wd in June 2013. On occasion he has issues with acceleration in that he steps on the gas to go (from a full stop), or steps on the gas to speed up (and pass) and the accelerator does not respond. After anywhere from 3-10 seconds it will lurch forward and go. This is an inconsistent/random occurrence. He has taken it to 2 dealerships and they can't seem to find anything wrong.

View 1 RepliesYesterday I had my snow tires installed at Costco. Immediately afterward I noticed that the rear brakes squeak when I apply the brakes. I took the car back to Costco and asked them if they applied the proper torque or if anything unusual appeared during the change-over. They said no.... I loosened and retorqued the wheels and no change......they still squeak when I apply the brakes.
Questions: I assume there are wear indicators on the rear pads, could this be causing the squeeling? If so, aren't they supposed to squeel all the time when they reach their limit? I haven't inspected the wear yet...... What the tolerance is for the amount of lining on the pad. Could this be a rotor problem? I"m not feeling any pedal vibration.
Our gen 1 has developed a (currently minor) noise issue when braking. I'd like to sort it out before it becomes serious.
The brakes are still strong, and the regenerative system appears to be working. When the brakes are applied (even gently) there is a pulsing raspy sound, seems like it is coming from the front, driver's side. It is more rapid at higher speeds, and louder during rapid deceleration. I guess I'd call it 'grinding', although this is much less unpleasant than the classic 'grinding brakes' I've heard on other cars.
In any other car I would figure a warped rotor or worn out brake pad. But I had imagined that the regenerative system handled light braking, and conventional brakes took over beyond a certain threshold. Now I'm hoping they work in tandem, even on gentle braking and this is just a boring, simple pad issue.
I've had my 2011 Prius II for two months, and I love it. One little thing bugs me, however. I have noticed that sometimes when I apply the brakes, the car lurches forward a little bit. But I keep the brake pedal on, and the car does stop. Is there something wrong with my brakes, or is this something that has to do with the regenerative braking?
View 19 Replies2008 Passat Komfort Wagon with 34,500 miles. Started to get grinding sound when I applied brakes, which diminishes as I drive. Thought it was rust, but sound is very loud and sounds just like pads are gone and digging into rotors. The brake warning light is not on.
Dealer told me rear caliper was closing unevenly and recommended service---not covered by warranty of course. When I picked-up car same noise as before. The service manager told be that the car was just washed and the rust built up in the last hour---I could believe some built-up, but the sounds made my teeth ache. When we went for a test drive the noise got quiter, but was still apparent. The SM told me this is a "normal" noise. I have had many cars with disc brakes, dating back to a 1960 Jaguar; none have made this "normal" sound.
