When other electrical problem gets reported

Owners of the 2001 Chevrolet Blazer report other electrical problem at a median of 50,000 miles. A quarter of the reports come in before 45,000 miles and a quarter after 60,000 miles, from 9 reports that carried an odometer reading.

A part like this is normally expected to survive 85,000 miles. It is the 4th most-reported problem on this model year.

The mileage distribution

The reported range runs from 40,000 miles at the tenth percentile to 100,000 miles at the ninetieth, a spread of 60,240 miles across the middle 80% of reports.

When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.

11% of the dated reports were filed under 36,000 miles.

The whole distribution

Percentiles of the 9 odometer readings owners gave.

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, 3 a fire and 2 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 2001 has 24. 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.

Gas gauge goes to empty and "low fuel" light comes on at anytime while driving, stays on for several seconds to several minutes and then gauge goes back to correct reading and light goes out. After several weeks of this "service engine soon" light came on. Personal technician reported that this is a common problem in vehicles of all brands and related to, the gas cap. Advised to turn gas cap for at least 3 clicks when done fueling and not to take the cap off the tank when the motor is running. Replaced gas cap and reset the computer, it was fine for 2 weeks. Gauge acting up again, mechanic going to pull tank and check if a lose baffle is interfering with the sending unit. May have to replace sending unit. *la

46,000 miles NHTSA complaint 433495 filed 2003-10-04

I am pregnant and very scared to drive this vehicle again. I was told by rick, service manager, toni hall at flow chevrolet a year ago that this 4x2 and 4x4 wheel drive was corrected while under warranty. They refused to fix the major problem and changed out a switch. During this whole year I haven't been able to drive comfortablly. Now they have had to replace the whole front end. A brand new car now with only 39,000 miles. The noise is terrifying and I've been insulted by gm with a loyalty incentive for $700 to take off on a new vehicle. No one can asure me that I will be safe, even after they told me it was fixed a year ago. I'm scared to drive it. I will leave it at their place until they can get me a safe car to drive.*ak

Caller stated that vehicle was in park with the ignition off, and about fifteen minutes after caller parked the car, someone notified him that the vehicle was on fire and burning heavily. Fire seemed to be confined to the engine compartment. Caller speculated that the fire began on the passenger's side of the engine compartment. By the time the fire department showed up, the fire was put out through the application of water.*ak

How far this goes

Complaints are voluntary, so 24 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 2001 Chevrolet Blazer?

Across 9 owner reports that included an odometer reading, half were filed by 50,000 miles. A quarter were filed before 45,000 miles and a quarter after 60,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is other electrical problem on the 2001 Chevrolet Blazer?

24 reports have been filed with NHTSA, about 0.5 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.
