Other engine problem on the 2017 Lexus Rx350
Only 5 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 5 reports of other engine problem on the 2017 Lexus Rx350, 5 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 4th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 4,500 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 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 2017 has 5. 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.
When accelerating hear a loud groaning noise and feel a hesitation in the gas accelerator pedal. Have brought to the dealer 3 times, as it seems to be getting worse. Dealer acknowledges their is an issue, but says will not fix because their is no recall. They said will notify us if/when lexus has a remedy. Apparently this is happening on 2016 & 2017 models. I am worried that my car is just going to lose power when accelerating as it seems to be getting worse and louder groaning noise. This happens first thing in the morning when the car is cold and accelerating between 0 to 20 MPH.
Tl* the contact owns a 2017 lexus rx350. While driving various speeds, the vehicle began to hesitate while the accelerator pedal was depressed. There were no warning indicators illuminated. The vehicle was taken to an unknown local dealer, but the cause of the failure could not be determined. The vehicle was taken to another dealer (bell lexus north scottsdale, 18555 n. Scottsdale, scottsdale, az 85255) where it was diagnosed that the computer software needed to be updated. The contact took the vehicle back to the unknown local dealer and was informed that the failure could not be repaired. The vehicle was being serviced as a lemon law vehicle. The manufacturer was notified and confirmed the information provided by the dealer. The failure could not be remedied. The failure mileage was approximately 4,500.
At 1800 miles, vehicle started to hesitate when pressing on gas pedal. When accelerating from stop, vehicle is hesitating and studdering very badly. This is affecting accelerating and causing a severe safety issue while driving. While at highway speeds, vehicle constantly is lunging hesitating when trying to merge into traffic. This has almost caused 3 accidents as in stop and go traffic, when pressing on gas to accelerate, car is shuddering and not finding right gear. Do not feel safe in car. Feels like car is going to stall out !!

How far this goes
This page is kept out of search results because 5 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 5 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 2017 Lexus Rx350?
Across 5 owner reports that included an odometer reading, half were filed by 5,000 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 2017 Lexus Rx350?
5 reports have been filed with NHTSA, about 0.2 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.
