2009 Lexus Rx350 at 55,500 miles

You did not give a mileage, so this uses 55,500 — the median reported failure mileage for this model year, which is a rough stand-in for “a typical example of this car”. Put your real reading in the box below for an answer about your car.

At 55,500 miles on this car

At 55,500 miles on a 2009 Lexus Rx350, 13 of the failure modes other owners have reported already have their median report at or below your reading, and 0 more fall inside the window where they are usually reported. The heaviest of the ones already due is steering rack, gear or tie rod failure.

Why the list is generic until you type a number

Every figure below is a comparison against your odometer, so with no reading given the page has to pick one: 55,500 miles, roughly what a 2009 car covers at 12,000 miles a year. A reading 30,000 miles either side of that moves failures between the columns, which is the difference between a useful list and a generic one.

Already inside the reported range

13 failure modes on the 2009 Lexus Rx350 have a median reported mileage at or below 55,500: steering rack, gear or tie rod failure (median 55,000 miles, 15 reports), other body or interior problem (median 55,000 miles, 12 reports), other steering problem (median 50,000 miles, 9 reports), other powertrain problem (median 30,000 miles, 6 reports), other electrical problem (median 50,000 miles, 6 reports) and other brake problem (median 10,000 miles, 4 reports).

These are the ones worth mentioning to a mechanic by name at the next service. Being past a median is not being overdue — it means the reports cluster below where you are now, so if the failure was going to be typical, it would already have happened.

Still ahead of you

12 further modes sit above your reading, the nearest being stalling while driving at a median of 70,000 miles. On a car you intend to keep, these are the ones that decide whether it is worth keeping.

What this list is not

It is a reading of what owners of other 2009 Lexus Rx350s reported, and at what odometer reading they reported it. It is not a maintenance schedule, not a diagnosis, and not a prediction about this car: two identical cars with different service histories are not the same car.

Complaints are filed voluntarily, mileages are typed in by owners and cluster on round numbers, and a failure mode with few reports has a wide window even when the median looks precise. Modes with fewer than 8 dated reports are shown without percentiles for that reason.

Where 55,500 miles falls on the curve

The three columns above sort the failure modes one by one. This is the same evidence in aggregate: every dated report on this model year, stacked up in the order the odometer readings arrived. The dashed line marked you is where your car sits. How much of the line is to the left of that mark is how much of this model year's reported trouble is, on the evidence, already behind you.

Share of reports filed by each mileage, with your reading marked
you: 56k

About 39% of the dated reports on this model year had already been filed by 55,500 miles. That is the share of the problems that show up in this record, not of the problems this car will have.

  • Line share of reports filed by that mileage
  • Dashed the mileages called out above

A steep early climb means a car whose reports cluster young, which is the pattern of a defect rather than of wear. A line that only gets going past six figures is the opposite. Neither shape says anything about the specific car in your driveway, and a curve built from a few dozen readings can be moved by one owner with a talkative afternoon.

Questions this page answers

What should I expect at 55,500 miles on a 2009 Lexus Rx350?

13 of the failure modes owners have reported on the 2009 Lexus Rx350 have a median report at or below 55,500 miles, and 0 more fall inside the mileage window where they are usually reported. That is a watch list drawn from other owners, not a prediction about this car.

How to use the three columns. The left column is the list to hand a mechanic before you buy, and to check the service history for if you already own the car. The middle column is what to budget for this year. The right column is not a reprieve — it is a reminder that a used car has a bill schedule, and this is roughly where it falls. All of it is drawn from 114 owner complaints about this exact model year, not from a maintenance manual. How the percentiles are computed.
