Parking brake failure on the 2015 Jeep Renegade
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 parking brake failure gets reported
There are 5 reports of parking brake failure on the 2015 Jeep Renegade, 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 88,000 miles. It is the 34th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 700 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
Putting it right typically runs $250–$1,300 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 5 model years of this car. It shows up earliest on the 2015, at a median of 700 miles, and latest on the 2018 at 20,000 miles.
By volume the 2016 carries the most reports, with 40; the 2015 has 5. 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.
On 7-23-2014, when attempting to back up, the jeep would not move and no less than 5 warning lights came on. Multiple messages:service hill start assist, service engine, service electronic parking brake, service transmission. Shifted to park, huge clunk, shifted back to reverse, huge clunk, then was able to back up. Shifted to drive, wouldn't move. Repeated process, clunking transmission, then moved forward. Drove home slowly then had towed to dealer. See online that the 9 speed 948te auto transmission is a problem. Why isn't anyone looking at this?? Dealer has jeep and has done 7 software updates and aren't sure if it will fix the problem. I paid $28,000 and don't know if the &#@% thing is going to do this every time I leave the driveway. Please look into this. I understand the 2013 forward cherokee has the same problem and no one is helping these owners either.
When using "autostick" to downshift the 9-speed automatic transmission the computer "unloads" the drivetrain and at times it feels like the car is being shot out of a canon. This is worst at higher speeds, when towing, and on downgrades. It happens when shifting from 8 to 7 and 5 to 4. The dealership told me that the car is operating "as designed" so they can't do anything. The other fix is a software update but I've gotten all available and the problem persists. Jeep has the same attitude. When using autostick to downshift from 5 to 4 on a 9% downgrade the car speeds up from 45mph to 50 MPH during the 2 second shift. Then, because of overly conservative downshift protocols (the engine has a max RPM of 6500 but during downshifting the computer never lets it exceed 3000 RPM), the computer won't let me downshift the transmission at all, there is no engine braking and the car keeps gaining speed. As long as the brakes are working there is help but without normal brakes there is no way to slow the car. The computer keeps saying no to a downshift and there is no emergency brake, only a parking brake that is either all off or all…
This vehicle has no mechanical parking brake, which would seem to be a violation of cfr-2010-title 49-vo l5-sec 393-41. The electric parking brake is pretty well useless, and necessary since this vehicle has a manual transmission, and a tiny (1.4l) engine incapable of holding the car on a steep hill. Error massage about electronic parking brake problems keep popping up, the dealer has been unable to fix it despite many repeated attempts. Even when working, it cannot be used to turn the car on snow, ice., etc. As I said: useless.

How far this goes
This page is kept out of search results because 5 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 5 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 parking brake failure happen on the 2015 Jeep Renegade?
Across 5 owner reports that included an odometer reading, half were filed by 700 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 parking brake failure on the 2015 Jeep Renegade?
5 reports have been filed with NHTSA, about 0.1 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.
