Other engine problem on the 2015 Chevrolet Silverado
1 fire 1 of the 10 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 other engine problem gets reported
Owners of the 2015 Chevrolet Silverado report other engine problem at a median of 10,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 25,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 1,500 miles at the tenth percentile to 60,000 miles at the ninetieth, a spread of 56,660 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.
80% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 1,540 miles | 3,123 miles | 8,888 miles | 26,600 miles | 58,200 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 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 $300–$4,000 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 21 model years of this car. It shows up earliest on the 2014, at a median of 2,000 miles, and latest on the 2008 at 85,000 miles.
By volume the 2001 carries the most reports, with 62; the 2015 has 10. 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.
Driving towing a travel trailer. Felt a vibration. Pulled over and nothing visible. Resumed but engine had no power. 30 MPH max speed. Called onstar and they could find no codes. Tried to continue but no engine power beyond 30 MPH.. Called onstar again and this time they identified 2 codes. Dropped trailer at a church parking lot. Truck now in reduced power mode and leaking liquid. Arrived at a dealer who identified problem as return fuel line had become disconnected. They reconnected and truck ran normally. Approximately 20 gallons of diesel fuel had leaked during this 8 mile ordeal. *tr
Tl*the contact owns a 2015 chevrolet silverado 3500. The contact stated that while the vehicle was parked, a fire started on the engine compartment that consumed the vehicle. The vehicle was destroyed. There was a police and fire department report filed. The manufacturer was made aware of the failure. The failure mileage was 30,000.
This is the 10th time this has happened, and 3rd time the vehicle has entered the service center. Own a 2015 chevy silverado 1500 crew cab z71, and when attempting to start the vehicle, it does not turn over, indicating that there is a theft deterrent issue. The first time the dealer was unable to replicate the issue or error code. The second time several error codes were present, which the dealer reset. This appeared to fix the issue, until 1 month later the issue presented itself again. The vehicle is currently with the dealer on it's third repair attempt. This can be very unsafe for a vehicle since in an emergency need the vehicle could be incapable of being driven.

How far this goes
Complaints are voluntary, so 10 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.

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.
