Not that beleaguered automaker General Motors needed any more bad news, but now the company is recalling nearly 1.5 million vehicles because an oil leak could cause an engine fire. Affected vehicles are all powered by GM’s 3.8L V6 engine (though only non-supercharged engines are being recalled) and include: 1997-2003 Buick Regal; 1998-2003 Chevrolet Lumina, Monte Carlo and Impala; 1998-1999 Oldsmobile Intrigue; and 1997-2003 Pontiac Grand Prix.
At the heart of the recall are three incidents where, under hard braking, oil has leaked from the engine and past a heat shield and splashed onto the exhaust manifold, catching fire. That fire spreads to a plastic spark plug wire guide and beyond. GM dealers will replace the spark plug wire guide with a redesigned version. (I have no clue how that fixes the problem, but apparently the government is satisfied.)
