2004 Lexus ES: what breaks, and at what mileage

What breaks on the 2004 Lexus ES

On the 2004 Lexus ES, the failure owners report most often is other speed control problem, with 5 reports on file. Across every failure mode on this year, half the dated reports were filed before 135,000 miles. Overall it scores 64 out of 100, high risk for a 2004.

High risk for a 2004 — 242nd riskiest of the 329 2004 vehicles we can rate. 21 owner reports; fleet size borrowed from other years of the same model.

What owners report breaking

Owners have reported 8 named failure modes on the 2004 Lexus ES, and the three most-reported carry 43% of everything filed.

Other speed control problem leads with 5 reports and about 0.5 per 1,000 vehicles.

Other engine problem follows with 2 reports, median 110,000 miles.

Other powertrain problem follows with 2 reports, median 5,000 miles.

By system, the reports fall mostly into adas (5), engine (2) and transmission (2).

When these failures get reported

15 of the reports on the 2004 Lexus ES came with an odometer reading, and half of those were filed before 135,000 miles.

Cumulatively, 40% by 50,000 miles, 47% by 100,000 miles and 73% by 150,000 miles of the dated reports had been filed.

The busiest stretch is between 130,000 and 140,000 miles, which alone holds 27% of the dated reports.

40% of the dated reports were filed below 36,000 miles, which is early enough that a fair number of these cars were still under a factory warranty when the owner complained.

What happens when these parts fail

Across the named modes, 7 mention a crash and 2 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 5.86, 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 speed control problem at $250–$2,000, other engine problem at $300–$4,000, other powertrain problem at $400–$4,500 and other body or interior problem at $200–$2,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

19% 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 2004 Lexus ES draws about 2.1 per 1,000 vehicles, which puts it in the 72nd percentile of complaint rates among 2004 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 10,142 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2004 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Other speed control problem

Dt*: the contact stated while driving 5 MPH in a parking lot, the vehicle accelerated forward crashing into the front window of a credit union. There were no injuries; there was property damage and a police report was filed. Prior to the incident, the transmission was hesitating and lurching forward. In 2004, the dealership determined that the vehicle's computer was trying to adjust to the way he drove. Updated 8/30/2006. *nm

Other engine problem

I had a car accident approximately one month ago due to sudden unintended acceleration and loss of steering in a 2004 lexus es330. I am the only owner of the car and I had it serviced regularly over the past 13 years. The night of my accident I lost complete control of my car as I attempted to merge on to the local lanes of an interstate highway in northern, nj. The car accelerated to the left and crossed sped across 8 lanes of the highway, including over a median before it spun around and jerked to a stop in the left lane of the west bound lanes facing east. I was hit head on by another driver. I was not injured, but the car was a total loss. Both of my parents also currently drive lexus vehicles, and both models were noted to have similar issues. Furthermore, my mother recently received a letter indicating her car was being recalled due to the passenger air bag issues, the letter stated while toyota would offer what they considered to be a suitable fix at no charge. The letter further explained that they did not currently possess the parts needed for the repairs and would be in touch in the future, no indication of the expected…

135,000 miles NHTSA complaint 1358409 filed 2017-02-24

The driver was pulling into a parking space at the local train station. She was going forward at about 1 MPH with her foot on the brake pedal in order to slow the car down as she was approaching the curb at the front end of the parking space. With her foot on the brake pedal, the car suddenly lunged forward and went over the curb and into a metal and wooden fence. The car probably would have landed on the train tracks; but, fortunately, it went into the fence which is used to support a shelter that shields commuters from inclement weather. The damaged fence is owned by the union pacific railroad. The driver suffered a back injury and required medical attention, medication, and physical therapy. The incident was reported to lexus in torrance, ca. Lexus has a contractual arrangement with a vendor to inspect the event data recorder (edr) installed in the car. After the edr was inspected, the driver was informed that the edr in the 2004 lexus es 330 is very basic and not at all sophisticated enough to detect what actually occurred immediately before and after the accident. Lexus said the edr in the newer es automobiles would have been…

How it ranks in the 2004 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 2004 field

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

  • Left fewer and less serious reports
  • Right more, or worse
  • Marker this vehicle

Where 2004 sits in the model line

High risk for a 2004 — 242nd riskiest of the 329 2004 vehicles we can rate. Because the ranking is against the same model year only, age cancels out of it.

Across the 14 model years of this car that carry enough reports to score, 2021 comes out best at 52 and 2019 worst at 86, with 2004 itself at 64.

If the model year is negotiable, 2021 scores lower than 2004 by a margin worth acting on. Same body, same engines, different luck — usually a supplier change or a mid-cycle fix, which the complaint data can show but never explain.

Within the 2000–2005 generation specifically, 2004 is the strongest year at 64 and 2005 the weakest at 75.

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 2000-2005 generation, 2004 Lexus ES scores best at 64 and 2005 Lexus ES worst at 75.

Where these figures stop being useful

21 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 21 reports, 15 carried an odometer reading, so the mileages here describe 71% 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 2004 Lexus ES?

The most-reported failures are other speed control problem (5 reports, median 25,000 miles), other engine problem (2 reports, median 110,000 miles) and other powertrain problem (2 reports, median 5,000 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.

Is the 2004 Lexus ES reliable?

It scores 64 out of 100 on our risk index, which is high — 242nd riskiest of the 329 2004 vehicles we can rate. The score is a comparison against other 2004 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 ES is best?

Within the 2000–2005 generation, 2004 scores best at 64 out of 100 and 2005 worst at 75. 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.
