Other engine problem on the 2010 Lexus Rx350
1 crash 1 of the 8 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 2010 Lexus Rx350 report other engine problem at a median of 130,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 170,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 200,000 miles at the ninetieth, a spread of 195,690 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.
25% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 3,310 miles | 52,750 miles | 130,500 miles | 169,750 miles | 199,000 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
Of these reports, 1 a crash 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 9 model years of this car. It shows up earliest on the 2017, at a median of 5,000 miles, and latest on the 2010 at 130,000 miles.
By volume the 2007 carries the most reports, with 28; the 2010 has 8. 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 have a new 2010 lexus rx 350 keep stalling while I was waiting for traffic light, problem stated soon after I started driving , while mileage was around 1500, when the car stalled ABS (anti brake system) sign showed up. I took the cars several times back to lexus, they used their computer to check computer records of my cars and claimed nothing wrong with the car, until the third time I went back , the brake malfunction warning sign showed up while lexus's technician was inside the car with me, then they kept the car 10 days and repaired the problem, but still claimed nothing else is wrong with the car, cannot explain why the car stalled, they claimed computer of my car didn't record any stalled history therefore no proof car stalling problem. I told them the computer of my car is so defect that they didn't find brake malfunction problem until the sign showed up in dashboard, why are they still rely on the computer? They kept the car for 10 days to repair a brake, how come it takes 10 days? I believe they found out that the car has more than brake problems, and they know all the lexus car has potential pending problem, either…
As I reverse out of my driveway, which is on an incline, onto a flat main roadway, the vehicle stalls (while still in reverse). This has happened multiple times on my 2010 lexus rx 350, as well as previously on my 2008 lexus 350. *tr
The engine makes a noise like a sloppy piston or a rod knocking. The car is a 2010 lexus rx350 with 69,000 miles. What is interesting here ia the fact that the issue was discussed with the service group on a recent confrence call but the staff was told to keep it quiet. Is toyota playing the games again? *tr

How far this goes
Complaints are voluntary, so 8 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.

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.
