Fuel leak or fuel odor on the 2005 Mercedes Benz AMG E55
When fuel leak or fuel odor gets reported
Owners of the 2005 Mercedes Benz AMG E55 report fuel leak or fuel odor at a median of 70,000 miles. A quarter of the reports come in before 57,500 miles and a quarter after 90,000 miles, from 41 reports that carried an odometer reading.
A part like this is normally expected to survive 90,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 40,000 miles at the tenth percentile to 115,000 miles at the ninetieth, a spread of 74,856 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
7% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 40,000 miles | 57,000 miles | 70,125 miles | 90,000 miles | 114,856 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–$2,500 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 4 model years of this car. It shows up earliest on the 2006, at a median of 70,000 miles, and latest on the 2003 at 80,000 miles.
By volume the 2005 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
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.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
I smell strong gas odor at rear driver side, when I get the full tank of gas. I went to a shop and lift the car that I can see the gas leak around the tank. I just want to say this kind of leaking very dangerous, because under the tank is exhaust pipe. That would be fired when too much gas leaking and no mil light come on. Also no any recall for the problem when I call to ask the mb dealer.
After filling the vehicles tank with fuel, the vehicle will emit a strong fuel odor on the drivers side rear wheel well as if the fuel tank was leaking fuel. After inspection is was deemed that the fuel tank was faulty and was indeed leaking fuel when full. The issue has not yet been fixed due to the extreme cost of replacing the fuel tank at the dealer even though they admit that the part was known to be incorrectly manufactured. *tr
Tl* the contact owns a 2005 mercedes benz e55. The contact stated that the vehicle was serviced multiple times by the dealer for a manufacturer's voluntary recall for a defective fuel sender unit. The vehicle was still leaking fuel and the smell of fuel continued to emit from inside of the vehicle after the repairs. The vehicle was taken to back to the dealer. The manufacturer was not contacted. The vehicle was not further repaired. The failure mileage was 95,000 and the current mileage was 1114,000.

How far this goes
Complaints are voluntary, so 42 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 leak or fuel odor happen on the 2005 Mercedes Benz AMG E55?
Across 41 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 57,500 miles and a quarter after 90,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is fuel leak or fuel odor on the 2005 Mercedes Benz AMG E55?
42 reports have been filed with NHTSA, about 8.9 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.
