No-start or intermittent start failure on the 2018 Jeep Compass
3 fires 3 of the 72 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 no-start or intermittent start failure gets reported
Owners of the 2018 Jeep Compass report no-start or intermittent start failure at a median of 17,500 miles. A quarter of the reports come in before 7,500 miles and a quarter after 30,000 miles, from 35 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 6th most-reported problem on this model year.
The mileage distribution
The reported range runs from 7,500 miles at the tenth percentile to 42,500 miles at the ninetieth, a spread of 35,500 miles across the middle 80% of reports.
A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.
83% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 7,500 miles | 7,500 miles | 18,000 miles | 29,500 miles | 43,000 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, 3 a fire 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 $200–$1,800 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 9 model years of this car. It shows up earliest on the 2019, at a median of 2,200 miles, and latest on the 2015 at 135,000 miles.
By volume the 2018 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.
Vehicle would not start - error message parking break engaged. Push gas pedal and release brake. These operations were performed and the vehicle would still not start. It took several minutes and attempts to finally get the vehicle to start. This is not safe operation of the vehicle.
On friday march 30 2018, vehicle had 6000 miles and would not start. Extreme amount of steam was coming out of the exhaust. Car was towed to dealership. Internal engine issue (not clearly identified) caused the engine to internally explode leaving metal fragments all over the inside of the engine. The entire engine needs to be replaced. In addition the vehicle was missing a bolt in a bar in the undercarriage of the vehicle, which has been on order for several weeks. The undercarriage bar was an issue known previously.

How far this goes
Complaints are voluntary, so 72 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 no-start or intermittent start failure happen on the 2018 Jeep Compass?
Across 35 owner reports that included an odometer reading, half were filed by 17,500 miles. A quarter were filed before 7,500 miles and a quarter after 30,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is no-start or intermittent start failure on the 2018 Jeep Compass?
72 reports have been filed with NHTSA, about 2.6 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.
