In owners' own words
I used my horn to let someone know that they were in my lane, and all of a sudden my horn was stuck. The window clips on my car broke off, as I have read of these same complaints of other 2003 Oldsmobile Alero owners.
1200 miles after J02 recall car runs sluggish going up canyon. Stop car and engine is misfiring. Turn around and coast downhill in neutral until check engine light turns on then stop and park car for several hours.

Recalls for the 2003 Oldsmobile Alero: 3
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.
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 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.
