What Are Some Common 2003 Oldsmobile Alero Problems?
The most common problem with the 2003 Oldsmobile Alero is the failure of the passlock sensor in the ignition lock cylinder. This causes the security system to prevent the car from starting. Replacement of the lock cylinder corrects the problem.
The 2003 Oldsmobile Alero's second most commonly occurring problem is the failure of the turn signal switch. This causes the turn signal to flash when the switch is in the off position. Replacing the switch corrects the problem.
The third most common problem with the 2003 Oldsmobile Alero is the failure of the front window sash brackets. This causes the window to come off of its track. The brackets can be replaced to correct the problem.
The Alero's fourth most commonly occurring problem is the failure of one or more blower motor speeds. This is caused by the failure of the blower motor resistor. The motor and resistor must be replaced to correct the problem.
The fifth most common problem with the Oldsmobile Alero is the failure of the intake gasket. This allows the engine oil and coolant to contaminate each other. Severe engine damage can occur if this problem is not repaired immediately. Replacement of the intake gasket solves the problem.
The 2003 Oldsmobile Alero has been recalled by General Motors to replace the ignition switch. It was also recalled in 2004 for a sticking accelerator.
