Differential or transfer case failure on the 2007 Jeep Grand Cherokee
2 crashes 2 of the 27 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 differential or transfer case failure gets reported
Owners of the 2007 Jeep Grand Cherokee report differential or transfer case failure at a median of 80,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 90,000 miles, from 26 reports that carried an odometer reading.
A part like this is normally expected to survive 110,000 miles. It is the 9th most-reported problem on this model year.
The mileage distribution
The reported range runs from 30,000 miles at the tenth percentile to 112,500 miles at the ninetieth, a spread of 82,500 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.
15% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 30,000 miles | 54,750 miles | 81,000 miles | 90,000 miles | 112,500 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 $900–$4,200 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 23 model years of this car. It shows up earliest on the 2021, at a median of 5,000 miles, and latest on the 2016 at 125,000 miles.
By volume the 1999 carries the most reports, with 115; the 2007 has 27. 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.
Tl*the contact owns a 2007 jeep grand cherokee. While driving 65 MPH, the vehicle began to lose speed. The contact stated that the vehicle was serviced for the transmission control. Two days after replacing the transmission control, the shifter and transfer case failed. The manufacturer is aware of the failure and stated that they would investigate it further. The contact was advised to call NHTSA. The powertrain was unknown. The current mileage was 9,901 and failure mileage was 3,652.
Tl* the contact owns a 2007 jeep grand cherokee. The contact stated that upon acceleration, the gear independently shifted into neutral. The vehicle at first did not respond but rapidly accelerated within several seconds. The failure was recurring. The vehicle was previously taken to the dealer to have the transfer case updated however, the failure was not corrected. The manufacturer was contacted and advised the contact that the vehicle was not included in NHTSA campaign number: 13v175000 (electrical system, power train). The vehicle was not repaired. The VIN was not available. The failure mileage was 90,000 and the current mileage was 100,100. ..updated 12-05-13 *bf
On two occasions the transfer case has shifted to neutral on it own. One time it left me in the middle of the road with traffic. Also, 4WD low rand of transfer case does not work. There was a recall done, known as the "n23 recall" first, it was done incorrectly resulting in no low range. Second, it was redone correctly and it worked as it should. Now a couple months later it is shifting to neutral on it's own and no 4low. It is a known problem among jeep owners. The dealers only want to replace parts at customer's cost and very unsuccessfully. *tr

How far this goes
Complaints are voluntary, so 27 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 differential or transfer case failure happen on the 2007 Jeep Grand Cherokee?
Across 26 owner reports that included an odometer reading, half were filed by 80,000 miles. A quarter were filed before 55,000 miles and a quarter after 90,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is differential or transfer case failure on the 2007 Jeep Grand Cherokee?
27 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.
