How reports accumulate
Every report with an odometer reading, cumulative, from 0 to 200,000 miles. A further 6 reports came in above that, which is why the line stops short of the top. A curve that climbs early is a car with early problems, whatever its total.

Severity, and what it costs
Across the named modes, 14 mention a crash and 11 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 8.46, 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 powertrain problem at $400–$4,500, other brake problem at $300–$1,800 and seat belt or retractor failure at $200–$900. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
24% 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 2003 Lexus ES draws about 3.6 per 1,000 vehicles, which puts it in the 78th percentile of complaint rates among 2003 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 2003 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 turning from a side street onto a main road and applying the brake, the vehicle engine revved. Then, while pulling into a parking space at 3 MPH and applying the brake, the vehicle lunged forward and over a small embankment. The engine continued to rev for a short time. The vehicle was not inspected by a dealer.
Tl*the contact owns a 2003 lexus 300 es. The contact stated that the vehicle automatically accelerated while attempting to pull into a parking space. The contact depressed the brake pedal, but the vehicle continued to accelerate. The vehicle stopped only after it jumped a curb. The vehicle was towed to a dealer, but no failure was found. The contact has the repair invoice and pictures. The current and failure mileage were 50,313.*ak
Other powertrain problem
I own a lexus 2003 es. The transmission is performing unsafely! 1. At stop lights, while holding the car stopped with the brake, the trans wants to go and the car lunges forward. 2. At low speeds (20 -30 MPH) the car doesn't know what gear to be in. The trans will jump down causing the rpms to suddenly increase then slam into the next gear lunging the car forward. 3. My biggest concern driving downhill at highway speeds, when the brake is applied, the trans jumps out of overdrive into 4th gear lunging the car forward! I am afraid of what may happen when the road is wet! *nm
The car changes gear when braking to a stop or coasting. When I apply the accelerator the car may hesitate and the snap into gear and lunge forward or it may quickly go between two gears until it finally jerks into gear and lunges forward. I took this certified car to the dealer under warranty and they claimed to have updated the computer program but it is exactly the same as before. The car has now started to hesitate while driving on the interstate as if was changing gears but doesn't need too. T he car is under warranty but I am discouraged by my first service experience. *jb
Other brake problem
Driving out of my garage usually slowly and when I put my foot on the gas while in reverse to pull out the car just flew out into the street. The immediately tried to brake and couldn't work. When I hit a truck in the street behind me the car finally stopped. I had no control. This never happened before, a first time and a very frightening experience. The car is at the lexus authorized body shop waiting for the lexus inspector to go over the car. I would be afraid to drive this car in the future thinking this could happen again anytime. I'm the original owner and felt this is the best car I ever owned until now. *tr
How it ranks in the 2003 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.
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
Better and worse years of the same car
High risk for a 2003 — 248th riskiest of the 330 2003 vehicles we can rate. Every score on this site is a rank inside its own model year, which is what makes a 2004 and a 2019 comparable at all.
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 2003 itself at 65.
If the model year is negotiable, 2021 scores lower than 2003 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.
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
37 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 37 reports, 26 carried an odometer reading, so the mileages here describe 70% 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 2003 Lexus ES?
The most-reported failures are other speed control problem (6 reports, median 70,000 miles), other powertrain problem (5 reports, median 30,000 miles) and other brake problem (4 reports, median 260,000 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 2003 Lexus ES reliable?
It scores 65 out of 100 on our risk index, which is high — 248th riskiest of the 330 2003 vehicles we can rate. The score is a comparison against other 2003 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.
