Other driver assistance problem on the 2011 Hyundai Sonata
1 crash 1 injury 2 of the 31 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 driver assistance problem gets reported
Owners of the 2011 Hyundai Sonata report other driver assistance problem at a median of 60,000 miles. A quarter of the reports come in before 22,500 miles and a quarter after 85,000 miles, from 26 reports that carried an odometer reading.
A part like this is normally expected to survive 45,000 miles. It is the 31st most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 112,500 miles at the ninetieth, a spread of 102,472 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
38% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 9,000 miles | 23,500 miles | 60,000 miles | 83,913 miles | 111,472 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, 1 a crash and 1 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 $250–$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 16 model years of this car. It shows up earliest on the 2024, at a median of 100 miles, and latest on the 2019 at 125,000 miles.
By volume the 2007 carries the most reports, with 40; the 2011 has 31. 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.
I have a turbo limited sonata. It has a severe left pull. If I am driving on a flat surface and let go of the steering wheel, I would be off the road to the left in about 5-6 seconds. If I am accelerating, I would be off the road within 1-2 seconds. It is a real problem. My dealership does not have the specs to fix the issue. I called the next closest dealer and they also do not have a fix. I am constantly assured that hyundai is working on the issue, but lets face it, it has been over six months. I have lost faith that they are working on a fix. The newly sold 2011 sonata limited turbos are being sold with the 17" wheels, not the 18" wheels I have. Therefore, it looks as though they are trying to change it to fix the problem. But what about those of us with the 18" wheels? Do we have to wait until someone dies before this gets fixed? That is not acceptable to me. There are already over 165 complaints and I hope more are added daily. I am a repeat hyundai sonata buyer and very discouraged with the quality of safety in this car. Please investigate the problem and force a recall!
The "esc" indicator light (not the "esc off" light) frequently comes on and stays on. If you stop the vehicle and put it in park while this is occurring, the gear shifter will not work. You can not put the car in gear. Once you turn off the car and restart it, the light goes off. However, after 10-15 miles the light comes back on and stays on again. Dealer ran computer check and found no codes but the problem continues. I've had the car 2 days. *tr
Esc light came on in perfect dry conditions and then the car was unable to be put into gear. Turned car on and off a few times and it stopped and I was able to get it into gear. *tr

How far this goes
Complaints are voluntary, so 31 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.

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.
