I was wondering if anyone is having a LOCKING UP PROBLEM ON THEIR XA OR has had the Master Cylinder GO Out. Intermittent problem happens with no warning signals, front end nose dives and car starts skidding to the right, currently has 13000 miles has been having problem since 962 miles brake pads changed at 5K and again at 9K at the same time as master cylinder was changed, brake pads currently are at 5m front and 2m rear the car continues to lock up causing major front end damage from the asphalt it scapes on...are we the only one with this problem....please reply

The brakes shouldn't be locking up since the car comes standard with abs. Should all be covered under warranty. Problem is most likely the abs module.

The ABS according to Scion FTS inspectors is working fine, the brakes randomly lock up the Master Cylinder Brake Pads and Rotor Turned was covered under warranty the problem is this has not solved the problem.

keep taking it back to the dealer...the car is a hazard on the road. they have to fix it.

Has been there more that at our house this year. This last trip they kept it for 2 days. Time before 5 days.

so you damaged it skidding into a curb? yeah, that isn't a warranty repair issue. but yeah, you got to get that fixed. you could try taking it to a different toyota dealership.

Actually the curb was the only way to stop the vehicle or go threw a very busy intersection, The Master Cylinder was stuck engaged on the right when they changed it and they said that was why it would skid to the right but that was changed could it be no good again???

don't know. but i suppose if it is skidding to the right, for some reason the right brakes are getting more braking power than the left ones.

lemon law!!! SWEET!!! Use that, i mean it is your brakes that are failing, not your radio....

It's lemon law time......the dealer should have told you that by now.

I meet with Scion today,

It seems that the damage should be covered as well, it was caused by the defect. That fight might not be worth fighting, depending on what documentation you have... But, good luck and let us know!

I actually picked up some parts out of the street that fell off the car and they reinstalled them for me at no charge so I do have documentation for some reason documentation appears to mean nothing.

Thanks for the props! I changed my pads at 30k, went with ceramics....but they weren't worn out, I just couldn't wait....:lol:

That sounds more like the mileage we normally get on a set of pads on all of our other cars and even more on the rear, I am going on the third set on the front at 13K.

No, that is flat out wrong. Even if the driver rode with their foot on the brake, you'd be hard pressed to wear out 3 sets of pads that fast....have the rotors hot spotted?

Thanks I will look into that and also the ceramic pads you mentioned

I'd try another dealer or at least get an inspection from an independant mechanic about the cause of this. You don't play with brakes.

I would also take it to a different dealer. It seems the current one is not fixing your problems. I'm not sure what to say, but if the dealer has been doing all your brake work, I would beholding them responsible for the damages as well and demanding a rental until the problem was properly solved.

shouldn't the rental already be covered if the dealer keeps the car overnight?

Just ran into another thread with an xA experiencing something similar:

Clean sounds like a wise man.

I just came from my hearing and have a ten day waiting period to hear the results. I did learn something when Toyota tells you they are sending out an FTS inspector to inspect the vehicle we should all check credentials because the one that we met at the dealership that decided there was nothing wrong with our braking system was at the meeting today and when I asked him if he was a certified by the state of California to be a mechanic, I FOUND OUT HE IS NOT A MECHANIC AT ALL AND HOLDS NO MECHANICS CERTIFICATION.

That is the meeting I came from today it is with Toyota and National Center of Dispute Resolution. I will post results when I get them. Hope for Lemon Status. If not I will trade in and get new one.. I can only hope they will not resale this car but destroy it.

GOT LETTER IN MAIL TODAY FROM HEARING WON LEMON VERDICT.

Great!!! :clap:

Bossy, if possible, and if you are comfortable with it, could you please feed us some detail about the letter - and keep us informed, of course, about how things work out for you.

Couple ?'s....
I'm not sure how Scion does it, but in my last car, the master cylinder was ahead of the ABS pump in the circuit. Meaning, if one wheel locked up, it's most likely the pump's fault, not the MC. The MC feeds pressure to the pump, and the pump inhibits that pressure if the need arises.
The brakes randomly lock up. Meaning, just driving down the road, or while you are in the process of normal braking for whatever reason?

This is how mine reads:

After reviewing the complaint(s) and hearing the proofs and arguments of the parties and taking into consideration the applicable manufacturer's new vehicle warranty, and the applicable law including the applicable State Statue commonly referred to as the "Lemon Law," and after due deliberation, I find and Award as follows:

The Customer's request of Replacement/Repurchase is hereby: AWARDED

I have reached this conclusion because:

The customer provided what I deemed compelling evidence in support of her claim in the form of repair orders and her testimony that the problems with her vehicle involve a substantial nonconformity (i.e. brakes or braking system). It is my award that the vehicle be replaced or repurchased.

YAY for you!!! Glad you got some satisfaction and glad you are staying in the xA family!!

Manufacturer is saying they can not replace his vehicle.

Seems like they don't want to keep your business....Time to call Scion Corprate again....

Hi, Bossy. I have two things to say. First, your braking problem may be from a bad proportioning valve or an intermittent problem with the abs computer.

If you are having problems getting a replacement, you might have to force the issue. Let them know that you are well aware of the abundant availability of replacement vehicles. Then let them know that you do not appreciate their insincerity and that you are considering having an interview with the local newspaper about the mistreatment, lack of professionalism and ethics at their dealership

I would hope they will figure out what the problem is after they get it back to their Engineers at the Manufacturing Plant. I should hear more today. I have agreed to give Toyota 30 days to comply with the arbitrators decision. Then I will enlist the help of outside sources. The deadline for compliance is May 29, 2007. I hope this is resolved before that date, so as my son may have his own vehicle to drive to all his Senior Activities for High School.

I know it has been mentioned by tom, but look into your local lemon law, in my state is an issue has to be address four times then it is a lemon.

To be honest it sounds to me like your brake calipers are sticking which is why your pads are wearing out so quick as for the locking up part i dunno.... are you driving along and it locks up or is while you are stopping it locks up? cuz if its when you are stopping my guess would be a stickly caliper. if its while you are driving i have no idea then.

what was the final status of your claim? did toyota ever replace your vehicle?
