Other electrical problem on the 2002 Chevrolet Blazer
2 fires 1 injury 3 of the 8 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.
Only 6 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 other electrical problem gets reported
There are 8 reports of other electrical problem on the 2002 Chevrolet Blazer, 6 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 85,000 miles. It is the 10th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 31,025 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 fire and 1 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 $250–$2,000 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 13 model years of this car. It shows up earliest on the 2021, at a median of 20,000 miles, and latest on the 2000 at 130,000 miles.
By volume the 1996 carries the most reports, with 42; the 2002 has 8. 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.
Left work and arrived at gas station. Put vehicle from drive to park and car died. Started back up no problem. Got home, put it from drive to park; died again. Vehicle dies whenever put from drive/reverse into park. Took to dealership; couldn't duplicate. Taking vehicle to chevy for them to look over & run tests. *ak
I've had the blazer for one year and the fuses keep blowing taking out all dash information.I've had it in the shop three different occasions so far and the mechanic can't pin point the problem..(in other words they like to make you look as if your lying)my warranty does cover for them to look at it.but its time off work and inconvenience that it is causing that doesn't seem to matter to them..cheverolet don't want to work out anything to resolve this matter..
August 24, 2008, myself and my three daughters headed to church traveling along 91n in ct to exit 35 when another passenger car waived at us to get off the exit - not knowing why we got off the exit any way since that's the one we needed and as we slowed down an abundance of smoke came from the front of the car - I pulled over and the gentlemen continued to waive at us - not known to me why until we got out of the car and saw flames brewing under the car...immediately I sought after my children to get to a safe distance and called 911 - state trooper was at exit 33 so he arrived quickly however front of car already had flames coming up towards windshield - front of car was covered with flames before fire truck arrived (pictures available) - insurance company had inspection completed and according to the inspection (report available) reference was made to the point of origin being the electrical system...outside of emotional distress (seeking therapy) no physical injuries occurred. This fire left me without a vehicle and as a real estate agent my vehicle is everything...this vehicle also was our family car. *tr

How far this goes
This page is kept out of search results because 8 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 8 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 other electrical problem happen on the 2002 Chevrolet Blazer?
Across 6 owner reports that included an odometer reading, half were filed by 30,000 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 other electrical problem on the 2002 Chevrolet Blazer?
8 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.
