Loss of braking on the 2004 Acura RL

1 crash 1 injury 2 of the 1 report 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 1 report 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 loss of braking gets reported

There are 1 report of loss of braking on the 2004 Acura RL, 1 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 78,000 miles. It is the 2nd most-reported problem on this model year.

The whole distribution

Percentiles of the 1 odometer readings owners gave.
10th25thMedian 75th90th
— — 107,000 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

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 $400–$3,000 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, every year of the Acura RL

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.

My wife was entering a bend in the road and came upon a car stopped in her lane, with no brakes lights!!! She attempted to swerve to the shoulder but it was too late. She impacted the car in the rear, slightly offset to the right (passenger) side. The front of her car impacted slightly offset to the left (driver's) side. She braced for impact with her left hand on the wheel. The passenger side airbag (empty seat!) deployed but the driver's airbag did not!! The full force of the impact was absorbed by her hand, shattering her wrist. She needs surgery to piece it back together and the surgeon estimates a 12-18 month recovery time. She's a professional driver with ~20 years experience and drives a school bus for a living. No way should her airbag not have deployed. Her career and our financial well being is in serious jeopardy because of the severity of her injury. I've never sued anyone in my life and don't care for the practice, but I don't see how I can't, this is just not right. *tr

How far this goes

This page is kept out of search results because 1 report 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 1 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 loss of braking happen on the 2004 Acura RL?

Across 1 owner reports that included an odometer reading, half were filed by 105,000 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 loss of braking on the 2004 Acura RL?

1 reports have been filed with NHTSA, about 0.0 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.
