Other driver assistance problem on the 2009 Nissan Altima
When other driver assistance problem gets reported
Owners of the 2009 Nissan Altima report other driver assistance problem at a median of 80,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 115,000 miles, from 12 reports that carried an odometer reading.
A part like this is normally expected to survive 45,000 miles. It is the 19th most-reported problem on this model year.
The mileage distribution
The reported range runs from 30,000 miles at the tenth percentile to 125,000 miles at the ninetieth, a spread of 93,504 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.
17% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 32,496 miles | 55,600 miles | 80,000 miles | 115,500 miles | 126,000 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
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 15 model years of this car. It shows up earliest on the 2014, at a median of 2,000 miles, and latest on the 2003 at 130,000 miles.
By volume the 2019 carries the most reports, with 41; the 2009 has 12. 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.
Part 2 - confirmation number 10500119 part 1 --- I wanted to add that I purchased this car new in 2009. This will cost me out of pocket $685 and of course like a said previously the warranty of 3/36,000 being the years that expired first. I've only had this car 3 1/2 years you shouldn't have major problems like this with a car this early. This should be a big red flag to the nissan company!. *tr
Tl* the contact owns a 2009 nissan altima. While driving 45 MPH, the vehicle suddenly spun out of control into the median before coming to a stop independently. The failure recurred numerous times. The vehicle was towed away, but not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 80,000.
My car was not starting. It was indicated as no key. I called nissan customer care. They told that my cars warrenty expired on march 2015. My cars first registration date is november 2009. I have heared that the ecsl of nissan altima is having 6 years of warrenty. But I am told by the nissan authorised dealer - pinnacle nissan scotsdate phoenix that my warrenty expired. My car have not completed its 6 year and I am wondering how the warrently would void. I have replaced the part from my pocket as well, I am really disappointed. It would be great if nissan can refund the cost of replacing the part. Thanks, binu.

How far this goes
Complaints are voluntary, so 12 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

How common is other driver assistance problem on the 2009 Nissan Altima?
12 reports have been filed with NHTSA, about 1.8 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.
