In owners' own words
Engine fire engulfed the whole front end. There was a recall by GM #15757. Received a letter indicating possible engine compartment fire.
Since september of 2013 this is around the 5th time this happens. When you turn the ignition to start the car the engine just won't turn over.

Recalls for the 2003 Chevrolet Monte Carlo: 9
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 minivans, passenger and sport utility vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 225, "Child restraint anchorage system." The owner's manual does not explain the meaning of the location symbols for the child restraint lower universal anchorage system. This does not meet the requirements of the standard.
On certain Mini vans, passenger and sport utility vehicles, some of these vehicles have a driver's side air bag that may not deploy as designed. In addition, the air bag inflator could rupture. This could result in reduced capability of the air bag to protect the driver. Also if the air bag inflator ruptured, pieces of the inflator could strike and injure the vehicle occupants.
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.
