Intake Manifold Problems in 3.8L also.
By GMGotmeagain on
2002 Buick LeSabre Custom 4dr Sedan (3.8L 6cyl 4A)
The 2002 Buick LeSabre is plagued by faulty intake manifold gaskets just like all GM 3.1 & 3.4 litre engines. Expect to pay around $800 to get this fixed at least once every 12-15k miles. Other than this problem the brakes will need serviced annually if you drive primarily in the city. This is due to heaviness of vehicle and constant stop and go driving under these conditions. Great fuel economy on highway. I've gotten as high as 32mpg on vacation trips in this car at 70mph. Amazing. In the city forget. Avg is 18mpg.
Great ride and comfort. Styling nice and plenty of room.
