2008 Lexus Rx350: what breaks, and at what mileage

What breaks on the 2008 Lexus Rx350

On the 2008 Lexus Rx350, the failure owners report most often is other body or interior problem, and the reports cluster around 70,000 miles. The earliest to appear is other speed control problem, reported by a median of 35,000 miles. Overall it scores 65 out of 100, high risk for a 2008.

High risk for a 2008 — 272nd riskiest of the 356 2008 vehicles we can rate. 160 owner reports; fleet size borrowed from other years of the same model.

What owners report breaking

Owners have reported 29 named failure modes on the 2008 Lexus Rx350, and the three most-reported carry 28% of everything filed, which is an unusually even spread for one model year.

Other body or interior problem leads with 19 reports, about 0.7 per 1,000 vehicles and with the middle half of reports between 54k to 85,000 miles.

Other engine problem follows with 14 reports, usually reported between 80k to 145,000 miles. 2 of those reports mention a fire.

Other electrical problem follows with 12 reports, usually reported between 50k to 75,000 miles.

By system, the reports fall mostly into body (31), engine (19) and steering (15).

The mileage the reports cluster at

129 of the reports on the 2008 Lexus Rx350 came with an odometer reading, and half of those were filed before 70,000 miles.

Cumulatively, 28% by 50,000 miles, 74% by 100,000 miles and 95% by 150,000 miles of the dated reports had been filed.

The busiest stretch is between 60,000 and 70,000 miles, which alone holds 14% of the dated reports.

20% of the dated reports were filed below 36,000 miles.

In the order they tend to show up: other speed control problem around 35k, other brake problem around 35k, other electrical problem around 65k and other body or interior problem around 69k.

Severity, and what it costs

Across the named modes, 19 mention a crash, 5 a fire and 7 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.

The average severity weight across every report on this year is 4.55, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.

What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: other body or interior problem at $200–$2,000, other engine problem at $300–$4,000, other electrical problem at $250–$2,000 and other brake problem at $300–$1,800. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

18% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.

How often, against how many were built

Scaled by an estimate of how many of these cars exist, the 2008 Lexus Rx350 draws about 5.8 per 1,000 vehicles, which puts it in the 84th percentile of complaint rates among 2008 vehicles we can rate.

That denominator is the weakest number on the page and it is fair to say so plainly. This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model.

The working figure is 27,738 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2008 vehicles, which is what the risk score uses, is far more robust than the rate itself.

How it ranks in the 2008 field

The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.

Risk score against the rest of the 2008 field

Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.

How 2008 compares with the other years

High risk for a 2008 — 272nd riskiest of the 356 2008 vehicles we can rate. The comparison is always within the same model year, so an older car is never penalised for having had longer to break.

Across the 13 model years of this car that carry enough reports to score, 2013 comes out best at 64 and 2011 worst at 80, with 2008 itself at 65.

No other year of this model scores meaningfully better than 2008, so if this generation is what you want, the year is not the lever.

Within the 2004–2011 generation specifically, 2007 is the strongest year at 64 and 2011 the weakest at 80.

Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.

Risk score by model year, out of 100

Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.

Within the 2004-2011 generation, 2007 Lexus Rx350 scores best at 64 and 2011 Lexus Rx350 worst at 80.

What the numbers say to check

The mileages below are where the first quarter of reports for each mode had already been filed, which makes them the point at which a fault is worth looking for rather than the point at which it happens: other speed control problem from about 20k, other brake problem from about 25k, other electrical problem from about 50k and liftgate, tailgate or trunk failure from about 51k.

On a 2008 Lexus Rx350 with more miles than that on it, the useful question to put to a seller or a mechanic is whether other speed control problem has been dealt with, and if so with what parts and at whose expense. A car that has already had the repair is in a different position from one that has not.

Treat it as where to point the inspection, not as a prediction. A well-maintained example can sail past every mileage on this page, and a neglected one can fail well before the first of them.

What this page cannot tell you

160 owner reports; fleet size borrowed from other years of the same model. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.

Of those 160 reports, 129 carried an odometer reading, so the mileages here describe 81% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".

The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.

And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.

Questions this page answers

What are the most common problems with the 2008 Lexus Rx350?

The most-reported failures are other body or interior problem (19 reports, median 70,000 miles), other engine problem (14 reports, median 110,000 miles) and other electrical problem (12 reports, median 65,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.

At what mileage do 2008 Lexus Rx350 problems start?

Other speed control problem is the earliest failure mode to show up, with a median reported mileage of 35,000 miles and a quarter of reports before 20,000 miles. Across all failure modes on this year, the median report sits at 70,000 miles.

Is the 2008 Lexus Rx350 reliable?

It scores 65 out of 100 on our risk index, which is high — 272nd riskiest of the 356 2008 vehicles we can rate. The score is a comparison against other 2008 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.

Which year of the Lexus Rx350 is best?

Within the 2004–2011 generation, 2007 scores best at 64 out of 100 and 2011 worst at 80. Same body, same engines, different luck.

Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
