One problem related to underhood wiring has been reported for the 2004 Chevrolet Silverado. The most recently reported issues are listed below.
Truck cut out while on the freeway; able to get it restarted. Later while trying to get home it stalled in the middle of an intersection. Chevy service dealer knew exactly what it was-- he told me it was due to a broken wire primary at coil connector. That this happens all the time. Part was replaced at a cost of $141. 37. If this part is defective why is not recalled?.
