Fuel gauge or level sensor failure on the 2004 Buick Lesabre
When fuel gauge or level sensor failure gets reported
Owners of the 2004 Buick Lesabre report fuel gauge or level sensor failure at a median of 55,000 miles. A quarter of the reports come in before 50,000 miles and a quarter after 75,000 miles, from 16 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 4th most-reported problem on this model year.
The mileage distribution
The reported range runs from 50,000 miles at the tenth percentile to 90,000 miles at the ninetieth, a spread of 43,500 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 47,500 miles | 50,750 miles | 57,000 miles | 75,860 miles | 91,000 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $300–$1,200 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 4 model years of this car. It shows up earliest on the 2000, at a median of 35,000 miles, and latest on the 1998 at 120,000 miles.
By volume the 2000 carries the most reports, with 16; the 2004 has 16. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

My 2004 buick lesabre limited had about 49,000 miles when all of a sudden the gas gauge stopped working. It is most often pegged in the 6 o'clock position, which also is affecting the heat gauge. I called buick, after conferring with my mechanic who assured me it was the instrument cluster and not the fuel sensor in the tank. Buick made it sound as if they were going to fix the problem if I jumped through their hoops and take it to a dealer and pay $85.00 to put it on the computer. The computer confirmed that it was a malfunctioning instrument cluster, after waiting a week, buick called me back and said they were not going to fix the problem and that it was up to me to pay the over $600 to replace the cluster. I have not done so as of yet. Now the speedometer is totally useless. The car now has 52,000 miles and on a recent road trip, the gauge quit working all together. I consider it luck that I have not gotten a ticket yet. I can live without a fuel gauge since the dash computer tells me how far I can travel before running out of gas. I cannot, however, live without a speedometer. It has now become a safety issue. I know from…

How far this goes
Complaints are voluntary, so 16 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does fuel gauge or level sensor failure happen on the 2004 Buick Lesabre?
Across 16 owner reports that included an odometer reading, half were filed by 55,000 miles. A quarter were filed before 50,000 miles and a quarter after 75,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is fuel gauge or level sensor failure on the 2004 Buick Lesabre?
16 reports have been filed with NHTSA, about 0.5 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
