Other engine problem on the 1996 Toyota Avalon
1 injury 1 of the 20 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 other engine problem gets reported
Owners of the 1996 Toyota Avalon report other engine problem at a median of 115,000 miles. A quarter of the reports come in before 95,000 miles and a quarter after 165,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 65,000 miles at the tenth percentile to 190,000 miles at the ninetieth, a spread of 127,887 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 63,313 miles | 92,750 miles | 116,500 miles | 164,354 miles | 191,200 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 an injury 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 $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 17 model years of this car. It shows up earliest on the 2010, at a median of 900 miles, and latest on the 1996 at 115,000 miles.
By volume the 2006 carries the most reports, with 47; the 1996 has 20. 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.
Engine cut out/stalled in middle of expressway with no warning. Pulled to emergency lane, turned off engine, waited a while, turned engine back on, engine light was on. Took to dealership, who indicates it is oil sludge due to failure to change oil. Oil has been changed every 4000 miles. Getting no satisfaction at this point from dealer, who indicates minimum repair cost will be $3300 - $3500 for rebuilt engine. Made complaint to toyota corporate, who also are not providing assistance. Getting run around as complaint was filed, which they are sending back to regional office for handling. Regional office already indicated that they probably aren't offering any assistance. Engine has less than 65,000 miles on it. Bought it one year old with 29,000 on it. There is no reason for this car to have engine trouble with less than 65,000 miles on it. Only 35,000 miles have been put on the car in last 6 years. Toyota needs to stick by their product, and make repairs that are required. Consumers at being placed in very poor position, and we are being taken advantage of.
I am the owner of a 1996 toyota avalon and need a new engine due to oil sludge problems. My car is not covered under toyota's csp program although it has the same problems as the engines covered under this program. This has caused my family emotional and financial stress. *jb
I own a 1996 toyota avalon. My car has been putting out a white smoke during cold start-ups. I am adding two quarts of oil a week. I change my oil every 3,000 miles. I even replace some seals, believing that was the problem. Now the problem has come to a-head. My car stalled on the interstate going to work on july 13, 2003. The car engine light came on after it stalled. I was able to park the car and it will be my mechanic. I have read on this site that there has been others complain of the same problem. Please help us in not only finding the problem but fixing it. Thank you for your time and have a blessed day, michael t. Marchand.*ak

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.
