Vehicle2007 Chevrolet Impala LT 4dr Sedan (3.9L 6cyl 4A)
ReviewAt around 75,000 miles the 3.9L engine went from not using any oil and 29MPG gas usage on highway to using very excessive oil ie: 1 quart every 150 miles and fuel efficiency dropped to 23 MPG. Nothing could be found wrong with the engine, no exterior leakage, runs perfect, but oil disappears. GM finally admitted they had a problem, but would not pay for the fix for this engine.
Best FeaturesGood running economical car with good power and decent size.
Worst FeaturesGM should stand behind the engine defect on the 3.9L V-6 and do a recall/fix.
