Other engine problem on the 2002 Toyota Corolla
Only 7 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 engine problem gets reported
There are 10 reports of other engine problem on the 2002 Toyota Corolla, 7 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 95,000 miles. It is the 2nd most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 40,400 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 $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 26 model years of this car. It shows up earliest on the 2004, at a median of 10,000 miles, and latest on the 2021 at 100,000 miles.
By volume the 2020 carries the most reports, with 85; the 2002 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.

Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
While driving, the engine light illuminated on the dashboard. *jb dealership wouldn't service vehicle without any appointment. When the consumer took the vehicle for service, she was informed vehicle was out of warranty because of the mileage. The defective part. The dealer "good willed" the part since the vehicle was just outside of warranty and the consumer just had to pay for the labor. *ph *nlm
I am writing regarding an issue with my 2002 toyota corolla. I recently had to replace an emissions control device in my car, a charcoal canister due to it being clogged. I am concerned that this may be a wide-spread problem because on the day that I had my car repaired, I met another person at the toyota service station with the same issue and who also had a 2002 toyota corolla. However, fortunately for her she was still under warranty so she did not have to pay for the repair. The warranty for this part is 3 years or 36,000 miles. Unfortunately for me, I was at the 38,000 mark on mileage and so I was out of warranty. Before I had the car fixed, I contacted toyota customer assistance center at 800-331-4331 (reference #: 200309021930) and after a bit of back and forth, they informed me that they would good will the part to me since I was right out of warranty, but I would have to pay for the labor. As a side to this story, toyota north in mt. Kisco (where I purchased my car) labor fee to replace this part is a $90 diagnostic fee plus 1.5 hours labor adding to a total of about $225. After shopping around, I found that toyota city…
A few weeks back my car's check engine light came one (this was when the mileage was around 40,500). Since it was out of warranty so I took it to a aaa certified repair shop for investigation. I later came to know that the engine light was due to charcoal canister failure. Since the charcoal canister can only be obtained from the dealer so I later inquired about the repair cost. The total repair estimate was told to me around $480 which prompted me to search the web about similar repair issues. I came across several similar complaints related to charcoal canister for many toyota vehicles. I have always taken the car to the local toyota dealer for regular oil-changes,etc. I was alarmed that such an important part of the car would fail just a couple thousand miles after the warranty expiration. So I called the toyota assistance at 800-331-4331 on 6/3/2005 (reference # [xxx]). I was told that the dealer would contact me some time within the next 3-4 days but that never happened. Upon calling the toyota assistance center today again (6/16/05) I came to know that the dealer had never bothered calling me and had instead just left a…

How far this goes
This page is kept out of search results because 10 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 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.
Questions this page answers
At what mileage does other engine problem happen on the 2002 Toyota Corolla?
Across 7 owner reports that included an odometer reading, half were filed by 40,000 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 engine problem on the 2002 Toyota Corolla?
10 reports have been filed with NHTSA, about 17 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.
