Other electrical problem on the 1999 Toyota Corolla
Only 2 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 4 reports of other electrical problem on the 1999 Toyota Corolla, 2 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 14th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 35,000 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
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 24 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 2021 at 130,000 miles.
By volume the 2010 carries the most reports, with 51; the 1999 has 4. 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.
Replaced three denso starters in 1/2010, 9/2006, and 9/2003 in '99 toyota corolla with only 90k mileage in car. I believe these starters are defective because in 2003 mechanic replaced original denso starter with remanufactured denso. I had 42k mileage on car. He inspected the starter and the invoice states that the starter was defective. I emailed denso salesperson to complain about the product and request reimbursement. He said no because there is only 12k warranty on starter. Again I had a starter replaced in 2006, and 2010. Something is seriously wrong that I am replacing starters every three years. I have never had to replace a starter in my life. I want this company investigated and want my money back. *tr
1) key would sometimes not turn in ignition. This became more and more frequent. ) eventually the key would not turn to start the car and I could not remove it and had to call a tow truck. 3) the first time the ignition was under warranty and replaced free of charge. The 2nd time they gave me more trouble about it but fixed it free of charge. The third time they suggested that I change the key which I allowed them to do and I haven't had a problem since but they did charge me part of the cost. I belive the "key" and ignition system obviously had a design flaw. I don not have the old parts but I do have records of the repairs.*ak

How far this goes
This page is kept out of search results because 4 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 4 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 1999 Toyota Corolla?
Across 2 owner reports that included an odometer reading, half were filed by 35,000 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 1999 Toyota Corolla?
4 reports have been filed with NHTSA, about 23 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.
