On the 1995-2005 Chevrolet Cavalier, cavalier ignition switches develop worn contacts causing engine stalling while driving and intermittent no-start conditions. The ignition key can become difficult to turn, and the switch may lose spring tension allowing the key to move out of the RUN position from vibration. GM acknowledged this issue with service bulletins. A related but separate defect was carried into the Cobalt that succeeded the Cavalier.

On the 2000-2005 Chevrolet Cavalier, the Passlock security system frequently malfunctions, reading the wrong resistance from the ignition cylinder sensor and refusing to allow the engine to start. The security light flashes and the car cranks but will not fire. This commonly occurs in cold weather or after the ignition cylinder wears internally.
The temporary fix is to turn the key to ON (not start), wait 10 minutes for the security light to stop flashing, then turn off and restart. The permanent fix is to bypass the Passlock sensor by wiring a 2.2K ohm resistor in place of the hall-effect sensor in the ignition cylinder. Some owners replace the entire ignition lock cylinder assembly.

On the 1995-2005 Chevrolet Cavalier, both the 2.2L OHV and 2.4L Twin Cam engines in the Cavalier are prone to head gasket failure. The 2.4L is particularly susceptible due to the aluminum head and iron block thermal expansion differences.

On the 1995-2005 Chevrolet Cavalier, the 2.2L and 2.4L engines in the Cavalier are prone to intake manifold gasket failure, allowing coolant to leak externally or internally mix with oil. The composite gaskets deteriorate over time due to heat cycling. Dex-Cool coolant interaction with these gaskets accelerates deterioration.
Replace the lower intake manifold gasket with an updated Fel-Pro design. Flush the cooling system and switch to conventional green coolant if desired. Check the oil for milky contamination — if present, perform multiple oil changes to flush the system. Torque intake bolts to specification in the correct sequence.
