2004 Toyota Corolla: what breaks, and at what mileage

What breaks on the 2004 Toyota Corolla

On the 2004 Toyota Corolla, the failure owners report most often is other speed control problem, and the reports cluster around 42,500 miles. The earliest to appear is other engine problem, reported by a median of 10,000 miles. Overall it scores 69 out of 100, high risk for a 2004.

High risk for a 2004 — 125th riskiest of the 329 2004 vehicles we can rate. 560 owner reports; fleet size estimated from this year's own recall paperwork.

The failures owners actually file about

Owners have reported 49 named failure modes on the 2004 Toyota Corolla, and the three most-reported carry 20% of everything filed, which is an unusually even spread for one model year.

Other speed control problem leads with 47 reports, about 0.3 per 1,000 vehicles and with the middle half of reports between 22k to 70,000 miles.

Other engine problem follows with 39 reports, usually reported between 250 to 65,000 miles.

Airbag inflator rupture follows with 28 reports, usually reported between 6k to 190,000 miles.

By system, the reports fall mostly into airbag (68), adas (58) and engine (54).

At what mileage it happens

289 of the reports on the 2004 Toyota Corolla came with an odometer reading, and half of those were filed before 58,000 miles.

Cumulatively, 46% by 50,000 miles, 74% by 100,000 miles and 87% by 150,000 miles of the dated reports had been filed, with 12 filed above the top of the chart.

The busiest stretch is between 0 and 10,000 miles, which alone holds 17% of the dated reports.

37% 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.

In the order they tend to show up: other engine problem around 8k, other fuel system problem around 20k, seat belt or retractor failure around 25k and airbag failed to deploy in a crash around 43k.

How bad it is when it goes

Across the named modes, 63 mention a crash, 3 a fire, 32 an injury and 3 a fatality. 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 5.03, 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, airbag inflator rupture at $0–$0 and other visibility problem at $150–$1,400. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

13% 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.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. 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 Toyota Corolla draws about 3.8 per 1,000 vehicles, which puts it in the 77th 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. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.

The working figure is 147,951 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

I bought a brand new 2004 toyota corolla in may this year. A few days later I was driving on the free way and the new car accelerated by itself. I tried to step on the brake to slow down, it became uncontrollable. I was driving at 60 miles per hour. Finally I have to exit the free way and the car hit the divider and got totally crashed.*ak

Other engine problem

2004 corolla bought 32 days ago with 92 miles. Noticed sulfur smell when exiting vehicle only after first refill -- not noticed with fuel that came with it. Dealer said to try different gas and to make sure that my entire tank is empty before filling. Basically recommending that I wait. (they did say to fill the tank -- not just put in a couple gallons) after the second refill (and about 16 days since purchase) I noticed that the smell wasn't as bad, but a friend reminded me that it was particularly windy. I later noticed the smell when the wind calmed down. No luck with the third refill either. All of these are at different stations. Called the dealer again and they recommended that I now try the higher-octane fuel. Needless to say, the days are slowly passing. After talking with sales dept and the service dept about what can be done, they agreed to take it for a drive as soon as they learned that I smelled this from inside the car when driving. I sense that it is a more-serious matter if it gets inside your car. They gave me a loaner for the day -- another corolla le, which also smelled of sulfur. The service manager at the…

Unexpected and without warning while car is in drive and stopped in traffic or at red light, engine idle speed increases when compressor from heating/air conditioner unit engages (when heater/defroster or air conditioner are in use) resulting car to lunge forward. If hard and constant pressure is not applied at all times on brake pedal while stopped, car could lunge forward resulting in; rear-end collision with another car; auto/pedestrian mishap while stopped at a crosswalk or hitting another vehicle board side if at a four-way stop. This design defect needs immediate investigation by NHTSA and if found valid, require toyota to recall and repair all 2004 toyota corolla les at no cost to car owner. *la

Airbag inflator rupture

Got the takata recall. Last spring, we received a letter from motorcars toyota, cleveland heights that they had the parts so we made an appointment. When we arrived at the appointment we were told they did not have the parts and we would be informed when they were in. Never received a letter. This month received another notice of recall. Contacted motorcars toyota again. They said that they did not have the parts and would not for 2 months. We contacted another dealership in cleveland, metro toyota, and they made an appointment the following friday, then did the repair. Clearly motorcars toyota is not pursuing this recall like other dealerships. If someone in the cleveland hts area is hurt as a result, we would be happy to testify against motorcars toyota.

54,000 miles NHTSA complaint 1236370 filed 2015-11-08

Takata recall: I was told that the recall takes 3 hours. I can not be without a car for 3 hours. I tried to call the nearest toyota dealership and they couldn't even schedule this appointment over the phone. They said they were busy and would have to have an "adviser" call me back. I will need a rental car paid for in order to get this service done. I would think that this would the utmost of importance and systems/personnel would be in place to handle this more efficiently and more timely. Since this is the manufacturers' negligence, I expect toyota to deliver on it's legal commitment to pay for all costs associated with this burden. If it takes 3 hours, I need a rental car for 3 hours.

Recalls on the 2004 model year

NHTSA has issued 13 recall campaigns covering the 2004 Toyota Corolla, affecting an estimated 520,463 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.

The campaigns cover air bags:frontal:driver side:inflator module, air bags:frontal:passenger side:inflator module and air bags. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.

Recalls also distort complaint counts. Publicity about a campaign reminds owners that complaining is possible, so reports for a recalled component often spike after the recall rather than before it.

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.

How 2004 compares with the other years

High risk for a 2004 — 125th 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 31 model years of this car that carry enough reports to score, 1997 comes out best at 62 and 2010 worst at 82, with 2004 itself at 69.

If the model year is negotiable, 1997 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 2003–2008 generation specifically, 2004 is the strongest year at 69 and 2007 the weakest at 72.

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 2003-2008 generation, 2004 Toyota Corolla scores best at 69 and 2007 Toyota Corolla worst at 72.

What to look at before buying one

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 engine problem from about 250, other body or interior problem from about 5k, other fuel system problem from about 5k and airbag inflator rupture from about 6k.

On a 2004 Toyota Corolla with more miles than that on it, the useful question to put to a seller or a mechanic is whether other engine 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.

None of this is a diagnosis. It is a list of what other owners of the same model year reported, ordered by when they reported it, which is a good place to point an inspection and a poor place to stop.

What this page cannot tell you

560 owner reports; fleet size estimated from this year's own recall paperwork. 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 560 reports, 289 carried an odometer reading, so the mileages here describe 52% 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".

Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.

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 Toyota Corolla?

The most-reported failures are other speed control problem (47 reports, median 42,500 miles), other engine problem (39 reports, median 10,000 miles) and airbag inflator rupture (28 reports, median 80,000 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 2004 Toyota Corolla problems start?

Other engine problem is the earliest failure mode to show up, with a median reported mileage of 10,000 miles and a quarter of reports before 300 miles. Across all failure modes on this year, the median report sits at 58,000 miles.

Is the 2004 Toyota Corolla reliable?

It scores 69 out of 100 on our risk index, which is high — 125th 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 Toyota Corolla is best?

Within the 2003–2008 generation, 2004 scores best at 69 out of 100 and 2007 worst at 72. 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.
