ABS module or sensor failure on the 1997 Jeep Grand Cherokee
5 crashes 2 injuries 7 of the 62 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 abs module or sensor failure gets reported
Owners of the 1997 Jeep Grand Cherokee report ABS module or sensor failure at a median of 105,000 miles. A quarter of the reports come in before 90,000 miles and a quarter after 170,000 miles, from 11 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 7th most-reported problem on this model year.
The mileage distribution
The reported range runs from 85,000 miles at the tenth percentile to 235,000 miles at the ninetieth, a spread of 151,000 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 84,000 miles | 91,000 miles | 105,000 miles | 170,000 miles | 235,000 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, 5 a crash and 2 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 1997 has 62. 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 rotors warped. As a result the brakes wore out prematurely. A recall was issued for this male/model, and year. However, the vehicle was not included in the recall due to VIN. *ak the ABS light had come on due to the ABS pump assembly, there was a vibration when braking, and the rear brake pad were metal to metal. *sc
Dt: the contact stated that twice the driver's door had to be put back on. It had a defect in the body frame. The first time was in 4-04, the second time it was in 4-05. Currently, ABS brake system malfunctioned. A month ago, all of the pads on front and rear were replaced. Three days ago, the ABS light came on and would not go off. The contact took vehicle a service dealer, and they told him the control unit module and the hydraulic pump motor needed to be replaced at a cost of $2,300.00. *ak

How far this goes
Complaints are voluntary, so 62 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 1997 Jeep Grand Cherokee?
Across 11 owner reports that included an odometer reading, half were filed by 105,000 miles. A quarter were filed before 90,000 miles and a quarter after 170,000 miles. 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 1997 Jeep Grand Cherokee?
62 reports have been filed with NHTSA, about 0.2 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.
