One problem related to ignition has been reported for the 2002 Chevrolet Express. The most recently reported issues are listed below.
The vehicle shuts down without warning while driving, found a gm service bulletin stating to replace the distributor cap and rotor but have done that now 4 four times but this doesn't correct the cause just the effect. To date it has redendered our vehicle undriveible due to it's unrelibility. Gm isn't doing anything to help us our our wheelchair bound son who relies on this vehicle for medical appointments.
