Head gasket failure on the 2002 Toyota Camry
1 fire 1 of the 29 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 head gasket failure gets reported
Owners of the 2002 Toyota Camry report head gasket failure at a median of 110,000 miles. A quarter of the reports come in before 100,000 miles and a quarter after 140,000 miles, from 24 reports that carried an odometer reading.
A part like this is normally expected to survive 115,000 miles. It is the 10th most-reported problem on this model year.
The mileage distribution
The reported range runs from 100,000 miles at the tenth percentile to 155,000 miles at the ninetieth, a spread of 56,622 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 98,000 miles | 99,750 miles | 110,500 miles | 141,726 miles | 154,622 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 $1,400–$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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 7 model years of this car. It shows up earliest on the 2006, at a median of 75,000 miles, and latest on the 2019 at 160,000 miles.
By volume the 2003 carries the most reports, with 39; the 2002 has 29. 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.
I own a 2002 toyota camry purchased new from dealership and regularly maintained. The check engine light came on while my daughter was driving the car and so I took it to our mechanic who said it was a faulty sensor which he replaced. The next day the check engine light came on again while she was driving and she was just able to make it back to the mechanic's shop with the car running roughly. The mechanic advised that the engine (136,000 miles) had suffered a "blown" head gasket. He recommended replacing the head gasket but warned me that because of the aluminum casting of the engine that there was a good chance that when he removed the steel bolts they would strip out the aluminum threads and then I would be looking at a new engine. Unfortunately that is what happened - total cost to put in a reasonably "new" used engine (from a 2009 scion) was $5,800. I understand that things can happen and am not unduly upset that the head gasket was blown however, something as basic as knowing that you should not use steel bolts in an aluminum thread should be remedied by toyota. When a repair such as mine is undertaken there is a high…
Loss of coolant. Took to auto repair. Told to replace head gasket. Upon replacement of head, discovered head bolts would not tighten because threads in aluminum block were stripped. *tr
I kept hearing rushing water coming from somewhere but nothing seems to be wrong. So at the end of november my car ran hot I took it to the mechanic and was told the thermostat may need to be replaced. I replaced it'.it ran hot again the next day. Was told I had a coolant leak. To make a long story short' I need an engine! Stripped head bolts in the block, no not just a head gasket problem I was told the head bolts have let go from the block. I asked the mechanic for a write up of his findings: (paraphrased) 'the only option left is to remove the head, which requires an extensive disassembly (r and r cylinder head). After loosening the bolts in sequence, I notice the head bolts in the back of the engine are loose. From my experience in the field, I can confidently conclude that this only means one of two things: the bolts were left loose at the factory, or the bolts are stripped. ( I commonly have seen stripped bolts in the aluminum cadillac north star block discovered through leaking coolant.) next, I removed the head and sure enough, one bolt came out with aluminum in the thread...thus indicating a stripped bolt. My theory: the…

How far this goes
Complaints are voluntary, so 29 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 head gasket failure happen on the 2002 Toyota Camry?
Across 24 owner reports that included an odometer reading, half were filed by 110,000 miles. A quarter were filed before 100,000 miles and a quarter after 140,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is head gasket failure on the 2002 Toyota Camry?
29 reports have been filed with NHTSA, about 0.7 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.
