Master cylinder or brake booster failure on the 2011 Dodge Durango
2 crashes 2 of the 9 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
Only 5 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When master cylinder or brake booster failure gets reported
There are 9 reports of master cylinder or brake booster failure on the 2011 Dodge Durango, 5 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 92,000 miles. It is the 17th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 56,100 miles | — | — |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Of these reports, 2 a crash is mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $450–$2,200 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 7 model years of this car. It shows up earliest on the 2013, at a median of 15,000 miles, and latest on the 2004 at 140,000 miles.
By volume the 1999 carries the most reports, with 16; the 2011 has 9. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Weather conditions were snowy and icy during my daily commute. While in route to my place of work I was driving down a mild incline toward a stop light which had just turned red. I was traveling at a lower speed (30 to 35 MPH) due to driving conditions. Due to those icy conditions my ABS immediately kicked in as I approached the stop light. For a matter of seconds I had the brake pedal firmly depressed continuously all the way to the stop light and I could hear the typical ABS noise until my vehicle stopped. Once traffic resumed I could feel a difference in the pressure needed to apply and activate the brakes. As I continued driving the pressure I needed to apply for braking increased dramatically but with less and less response from the brakes. After only 1 additional trip I realized the need for service work and scheduled service. On my second trip after the initial incident braking became extremely difficult and the dashboard brake warning lamp came on. My third trip was to service which was scheduled and the brake booster was found to be the issue. Initially the supplying dodge dealer had told the repair facility which…
Chrysler issued a safety recall for the brake booster on my vehicle and said the dealership would install a protective brake booster shield to prevent water ingestion and premature corrosion. In the letter, mailed by chrysler, I was instructed to "contact my dealer right away to schedule a service appointment" and that the dealer would inspect my vehicle, and then either install the shield or replace the brake booster if required, free of charge. Upon receiving the letter, I contacted the service department at ziegler chrysler dodge jeep at 208 w golf rd schaumburg, il 60195 (847) 882-8400. I was informed that they do not have any parts in stock and they told me the safety issue is not a problem until below freezing weather, and "that he didn't expect any below freezing weather for a while". And then he complained because every call he is getting today is about this recall. They claim to be a 5-star service dealer. Shouldn't the recall process be more coordinated with dealerships? Why don't they have the shields as indicated in the recall letter? The service adviser implied that I can wait until winter before finding out if there…
Tl* the contact owns a 2011 dodge durango. The contact stated that after having the vehicle repaired according to NHTSA campaign number: 14v154000 (service brakes, service brakes, hydraulic) and having the brake booster replaced, the "push to start" button malfunctioned. The contact mentioned that the brake pedal did not have to be depressed in order to start the vehicle. In addition, the brake lights were constantly illuminated, as if the brakes were engaged, and the forward collision warning alert system was disabled. Also, the ABS would activate continuously, but only on the front driver side wheel. The vehicle was taken back to the dealer, but the cause of the failures could not be diagnosed. The manufacturer was not notified. The VIN was not available. The approximate failure mileage was 56,100.

How far this goes
This page is kept out of search results because 9 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 9 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does master cylinder or brake booster failure happen on the 2011 Dodge Durango?
Across 5 owner reports that included an odometer reading, half were filed by 55,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is master cylinder or brake booster failure on the 2011 Dodge Durango?
9 reports have been filed with NHTSA, about 0.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
