Loss of braking on the 2003 Chevrolet Tahoe
2 crashes 2 of the 34 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 loss of braking gets reported
Owners of the 2003 Chevrolet Tahoe report loss of braking at a median of 105,000 miles. A quarter of the reports come in before 67,500 miles and a quarter after 127,500 miles, from 31 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 52,500 miles at the tenth percentile to 177,500 miles at the ninetieth, a spread of 123,512 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.
3% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 53,000 miles | 68,500 miles | 105,831 miles | 128,001 miles | 176,512 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 $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 on other years
The same failure is reported on 18 model years of this car. It shows up earliest on the 2012, at a median of 2 miles, and latest on the 1996 at 145,000 miles.
By volume the 2001 carries the most reports, with 36; the 2003 has 34. 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.
The brakes failed to stop the truck when depressed between 10-15 MPH upon approaching a traffic light. This resulted in the truck rear ending another vehicle. All the dashboard warning lights and the check engine light started flashing an hour before the brake failure. Also, there was a rattling/thumping noise in the steering wheel when turning. The truck was towed to the dealership, who together with insurance company had to inspect the truck to determine the cause of the brake failure.*ak
Tl*the contact owns a 2003 chevrolet tahoe. While driving 5 MPH downhill and approaching a stop, the antilock brakes pushed back on the contact's foot. The vehicle became difficult to stop and another vehicle nearly crashed into the contact's vehicle. The dealer repaired the brakes under NHTSA campaign id number 04v045000 (service brakes, hydraulic). When the failure occurred a second time, the dealer had a technician inspect the vehicle. It was discovered that the antilock brakes failed and the vehicle was repaired at the cost of $200. The failure mileage was 53,000 and current mileage was 59,000.

On the evening of july 13 my wife was driving the tahoe when the check brake warning light came on. She was able to enter our driveway and stop the vehicle. The next morning I checked the vehicle and there was no resistance on the brake pedal and the pedal went to the floor. Looking under the hood I found the brake fluid reservoir was empty. The mechanic that repaired the vehicle found the rear steel brake line rusted out. The vehicle is only 11 years old and has 116,184 miles and I feel that it is a bit premature for the brake line failure due to rust. I owned two chevrolet's and a ford product for over 20 years each and never had a problem with the steel brake lines. *tr

How far this goes
Complaints are voluntary, so 34 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 2003 Chevrolet Tahoe?
Across 31 owner reports that included an odometer reading, half were filed by 105,000 miles. A quarter were filed before 67,500 miles and a quarter after 127,500 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is loss of braking on the 2003 Chevrolet Tahoe?
34 reports have been filed with NHTSA, about 0.9 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.
