The brake booster accumulator is leaking so it makes a 'chirping' sound from the left side of the vehicle. This is a recognized fault with this vehicle and a recall was issued I did not get notification of the recall so did not get it fixed. It has now become a problem which I am told could cause the brakes to fail, obviously a serious safety issue. I have spoken to Mitsubishi and they will not honor the recall.

The hydraulic brake booster, manufactured by aisin, failed due to a worn out pump motor. This is a brushed motor with no service interval so much as mentioned in either the owners manual or the factory service manual. Moreover, you can not purchase brushes for the motor from the dealer or anyone else. Here is a photo of the motor: I.imgur.com/dui0X0K.jpg as you can see it's completely worn out. This was taken after it was cleaned with compressed air. The motor was filled with the remains of the brushes and commutator. It is extremely irresponsible to power a breaking system with such a low quality motor and not even give it a service interval. When this motor fails, so do the brakes. Every single generation three Montero will suffer from this failure, some catastrophically. As more vehicles rely on electric power to stop, this is surely going to be an issue that NHTSA will be dealing with.

On July 8, 2014 I noticed that when I applied the brake pedal, I would hear a noise from the left side of my truck. I wasn't sure what it was and I asked a few friends to look at it. One indicated that it had to do with the brake assist and found under the hood where the noise was coming from. After that I did some research on the item and found through safecar.gov that this vehicle was apart of a recall from 2001 for the accumulator that is installed on the hydraulic brake booster. I am not the original owner of the vehicle and proceeded it to go the local dealer to have them fix this. I was told that the car had been fixed under the recall back in Nov 2001 and due to this they refuse to fix the item. I filed a complaint direct with Mitsubishi ([xxx]). this is obviously a known safety hazard and the Mitsubishi refused to fix a problem they know exists. How do I know if the part they replaced isn't also faulty. The recall report indicated that over a period of time, it could result is leakage of the pressurized nitrogen gas from inside the accumulator and could result in a crash. When I asked the cost to repair the item I was advised it would be $2,000. This is simply insane. They know they have a problem so now Mitsubishi raises the prices on the item so they can recoup the costs of the recall.

Was going down a hill when I couldn't press my brake pedal because it was too stiff! the ABS and brake light turn and with a constant beeping noise. Thankfully there was a hill going back up so I was able to slow it and pull it off the road fine. Glad it didn't happen at other points of my trip! my brake booster has gone bad and Mitsubishi says it's not part of the recall. Seems like they have a lot of problems with this and it's never part of the recall.

Recall on ABS accumulator was performed years ago. Brakes once again failed almost completely with wife and 3 children. Luckily she remembered the parking brake and was able to stop. New accumulator replaced and brakes were again fine for 3 days...complete failure again. Dealer informs us that the entire ABS assembly needs replaced at a total cost and labor of around (between) $2800. And $3600. The recalled part (the accumulator) I am finding is a direct result of the entire ABS assembly damage. If the pump tries and continues to try and fill the leaking accumulator the pump fails. As a result the pump and ABS control (brain) module are all in one and the entire assembly needs to be replaced. What recourse do we have? how can we get Mitsubishi to replace this defective "complete assembly" the vehicle is now useless as we save our pennies and scrape together what we can to fix a problem that we nor anyone else should have to fix. I see many reports of accidents due to this very problem. Please help!

When I step on the break pedal I hear a buzzing sound coming from the front compartment of the vehicle. The break is not functional since it is hard and stays up while I depress with my foot. While driving or when the engine is running I hear this sound periodical and a steady sound with the anti lock/ break light

I'm driving downhill when my brakes start acting up. It was so hard and no power brakes, I needed to use the hand brakes to make sure I wasn't going hit the car in front of me. Took to the dealer cost a couple hundred bucks for diagnostic and they said my power brake booster needed to be replaced. I cant afford to have it fix right away it cost few thousand bucks for the new one and I don't want put a used one because I'm not sure if its going to last. How come Mitsubishi motors can't help us for this they know these parts are not going to last. That's why they changed it and put a different one on their 2003 and up models.
