Other brake problem on the 2011 Hyundai Sonata
11 crashes 4 fires 3 injuries 18 of the 86 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.
When other brake problem gets reported
Owners of the 2011 Hyundai Sonata report other brake problem at a median of 75,000 miles. A quarter of the reports come in before 25,000 miles and a quarter after 117,500 miles, from 59 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 11th most-reported problem on this model year.
The mileage distribution
The reported range runs from 7,500 miles at the tenth percentile to 145,000 miles at the ninetieth, a spread of 136,900 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
34% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 6,900 miles | 24,000 miles | 75,149 miles | 117,500 miles | 143,800 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, 11 a crash, 4 a fire and 3 an injury are 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 $300–$1,800 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.
The same failure on other years
The same failure is reported on 21 model years of this car. It shows up earliest on the 2018, at a median of 10,000 miles, and latest on the 2020 at 120,000 miles.
By volume the 2012 carries the most reports, with 87; the 2011 has 86. 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

I purchased the 2011 hyundai sonata june 2010. I was really enjoying the new sleek look of the sonata. I have never owned any type of hyundai vehicle before. Well as I began to drive the vehicle - I noticed that there was a bit too much skidding on water or during rain fall. This was during a simple take off from a stop. January 2011 I was traveling at about 35 miles per hour light snow was falling but the roads were clear. As I was approaching traffic ahead the light turned green and traffic began to move. I noticed the car in front of me not quite taking off with traffic so I began to brake. To my surprise - guess what - the car was not stopping. My nice picture of the skidding car lite up and the vibration under the brake pedal started. So I let off and pressed again and there was still no stopping. I began to blow my horn in a panic to warn the driver ahead I was coming. (well as you all may or may not know - the horn is pretty lousy and according to the other driver - after I hit him - he didn't realize it was my car until it was too late.) I literally had my foot pressed to the floor blowing the horn and trying to stop this…
Failed components: brakes & shift gear the brake pedal is not working most of the time when shifting the gear from park to drive mode (followed by reverse mode) I need to press the brake pedal very hard up to several times to shift the gear. I brought the vehicle to the dealer and it works fine for two days. It started happening after two first services to the vehicle by dealer. I brought the vehicle again to dealer after 1 week and explained the problem again. They did some troubleshooting again, they told me that they didn't identify the problem this time. I spoke with hyundai customer support and they directed me to another dealer and asked me to document the problem. I took the vehicle to another dealer and they told me that this is a common issue and suggested that I unlock the "shift lock" in case of emergencies! I told them that shift lock is only useful in case of emergencies. But the brake pedal is not releasing the gear most of the time which is not acceptable. There is no answer from the dealer. Trying to contact hyundai official support but nothing heard back from them at (after 2 weeks.) status update 02/23/12
Tl* the contact owns a 2011 hyundai sonata. The contact stated that the push to start button switch failed. When depressing the brakes and trying to place the vehicle into gear, the vehicle would not move. The failure recurred on an intermittent basis. The vehicle was taken to the dealer and they advised him that the brake switch failed and needed to be replaced. The vehicle was repaired for the brake switch. The failure mileage was approximately 24,000. The VIN was unavailable.

How far this goes
Complaints are voluntary, so 86 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 other brake problem happen on the 2011 Hyundai Sonata?
Across 59 owner reports that included an odometer reading, half were filed by 75,000 miles. A quarter were filed before 25,000 miles and a quarter after 117,500 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other brake problem on the 2011 Hyundai Sonata?
86 reports have been filed with NHTSA, about 0.4 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.
