ABS module or sensor failure on the 2003 Jeep Grand Cherokee
1 crash 1 injury 2 of the 7 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.
Only 5 reports 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 abs module or sensor failure gets reported
There are 7 reports of ABS module or sensor failure on the 2003 Jeep Grand Cherokee, 5 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 95,000 miles. It is the 24th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 30,671 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 $500–$2,400 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 19 model years of this car. It shows up earliest on the 2014, at a median of 10,000 miles, and latest on the 2008 at 155,000 miles.
By volume the 1999 carries the most reports, with 91; the 2003 has 7. 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.
After conducting business at a drive in bank consumer proceeded to leave. Consumer placed foot on the accelerator and the vehicle accelerated. Then, he applied the emergency brake, however, it did not stop the vehicle. It stroke a four foot embankment, the only thing that stopped the vehicle was a concrete retaining wall, which was struck at 30 MPH. Upon impact, the air bags did not deploy, the emergency brake and the anti lock brakes did not kick in.*ak
I own two jeep grand cherokees 2003 models, both purchased in dec 2002. Both of these vehicles have had brake problems, consisting of warpped brake rotors. I have owned 9 jeep grand cherokees since 1992. 6 of the nine jeeps have had brake problems. 4 of those jeeps have had their brakes repaired or replaced at no charge to me. However the 2003 jeeps I currently own have the same problem. I have had them both repaired in 2004 and I am having the same problem in 2005. One of the jeeps has 13,000 miles since the 2004 repair and the second one has 7570 miles on it since the 2004 repair. My understanding of the problem is that the calipers used to apply pressure to the brake pads never fully release, therefore there is always some pressure being applied to the rotor and the rotor is warpped from the heat caused by the pad being constantly in contact with the rotor. *ak

How far this goes
This page is kept out of search results because 7 reports 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 7 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 abs module or sensor failure happen on the 2003 Jeep Grand Cherokee?
Across 5 owner reports that included an odometer reading, half were filed by 30,000 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 abs module or sensor failure on the 2003 Jeep Grand Cherokee?
7 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.
