In owners' own words
Engine coolant leak at the intake manifold, or at the lower intake manifold to lower intake manifold gasket. This condition may result in a low engine coolant level or coolant pooling on manifold.
Head gasket failure. Head gaskets are defective on the 3400 series engines. The coolant used in these vehicles causes premature erosion in the head gasket.
2002 chevy impala ls V6 engine, required to have intake manifold gasket replaced. The gasket had dissolved and was allowing oil and coolant to leak onto the engine block, and mix within the engine.

Recalls for the 2002 Chevrolet Impala: 7
The affected vehicles were previously repaired under recalls 08V-118, 09V-116, and 15V-201 to address the possibility that engine oil may drip onto the hot exhaust manifold. Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
This defect can affect the safe operation of the airbag system. The key fob (if applicable), should also be removed from the key ring. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
Some of these vehicles have a condition in which drops of engine oil may be deposited on the exhaust manifold through hard braking. If the manifold is hot enough and the oil runs below the heat shield, it may ignite into a small flame and may spread to the plastic spark plug wire channel and beyond increasing the risk of an engine compartment fire.
A potential material or design defect could result in the steering knuckle breaking in the hub area. A broken steering knuckle could result in loss of steering control and a possible crash without warning.
These replacement steering shafts can be used on the vehicles listed above. The weld connecting the inner tube to the outer tube may be defective. If the weld fails, loss of steering could result, possibly resulting in a vehicle crash.
Certain delphi fuel pressure regulators, p/nos. FP10020-11B1, FP10026-11B1, and FP10027-11B1, sold after january 9, 2007, as aftermarket equipment for various passenger vehicles listed above. The universal pressure regulators (Upr) were produced without an o'ring and retainer. Fuel may leak, possibly resulting in a fire.
Certain passenger, Mini vans, and sport utility vehicles have an air bag inflator on the driver's side that could fracture at a weld during a deployment. Pieces of the inflator could strike and injure vehicle occupants and the air bag cushion would not inflate fully, reducing the capability of the bag to protect the driver.
