Stalling while driving on the 1998 Buick Lesabre
Only 2 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When stalling while driving gets reported
There are 10 reports of stalling while driving on the 1998 Buick Lesabre, 2 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 75,000 miles. It is the 11th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 78,500 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 5 model years of this car. It shows up earliest on the 2002, at a median of 25,000 miles, and latest on the 1997 at 105,000 miles.
By volume the 1998 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.
The vehicle stalled while driving at 30-MPH without warning. The vehicle was taken to a local garage and they found that the intake manifold was cracked and caused coolant to leak inside the engine. *ph when the vehicle stopped, the consumer was unable to restart it, the engine was hydrostatic locked due to the coolant leaks. *sc *jb
On 07/21/03 my 1998 buick lesabre (VIN [xxx]), suddenly and without prior symptoms, began to run extremely rough and the engine stalled and was unable to be re-started. Fortunately, I was able to get off the road before the engine stalled. I am now saddled with a $2,000 repair bill all, apparently, as a result of the failure of the plastic gm plenum. The plenums failure caused other failures within the engine (including, but not limited to, the ignition control module and the starter). According to the mechanic that serviced the vehicle, this is not uncommon in gm vehicles that utilize the plastic plenum. I would seek restitution from general motors for what appears to be a historical and systemic failure of this plastic plenum resulting in extraordinary engine repairs.*ak information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

How far this goes
This page is kept out of search results because 10 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 10 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 stalling while driving happen on the 1998 Buick Lesabre?
Across 2 owner reports that included an odometer reading, half were filed by 80,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is stalling while driving on the 1998 Buick Lesabre?
10 reports have been filed with NHTSA, about 0.2 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.
