Major engine problems
By rahni on


2004 Buick LeSabre Limited 4dr Sedan (3.8L 6cyl 4A)


LeSabre's 2000-2004 are made with a
phenolic resin intake maniford that
warps and leaks antifreeze into the
engine's cylinders - basically blowing
superheated steam into the combustion
chambers. The factory-recall fix (put
locktight on 3 bolts) doesn't work.
According to a factory trained
mechanic, many engines have had to be
replaced because of this cheap
construction. Also, "permanently
lubricated" tie-rods wear prematurely
and have to be replaced at low milage.
Plastic window grips on electric
windows break easily.

Best Features

Battery under the back seat saves it from engine heat.

Worst Features

Aluminum or magnesium intake manifolds.
