In owners' own words
I was driving approx. 70 MPH on the highway in my 2003 grand am gt when all of a sudden, with no warning at all, my car shut off completely!!!!
Hi, my grandam overheated while I was driving. I noticed that the coolant compartment was empty. I did not receive a low coolant warning from the car system.
The ignition switch/rear hub assembly, and fan motor, have been either serviced and/or replaced due to fluids leaking out.

Recalls for the 2003 Pontiac Grand Am: 5
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.
These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." These lamps do not contain the required amber side reflectors. Decreased lighting visibility may result 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 tradesonic combination lamps sold as replacement lamps for use on the above listed passenger vehicles. Combination lamps not equipped with amber side reflectors fail to conform with the requirements of federal motor vehicle safety standard no. 108, lamps, reflective devices, and associated equipment. Lack of amber side reflectors in the lamps will decrease lighting visibility to other drivers and may possibly result in a vehicle crash.
Certain passenger vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 124, 'accelerator control systems.' in hot ambient conditions, the accelerator pedal arm may stick at the attachment to the bracket and not return to the engine idle position when the operator lifts his foot… Failure to return to idle could result in a vehicle crash.
