2008 Silverado 5.3l Flex have had intermittent starter issues since purchased. Approx. every 2 years replacement of relay. 2years ago new starter. I turn key and dash lights up as normal and then lights go out and dash darkens. No noise under hood. Can anyone suggest why this would occur approx. every 2 years and not a constant issue.

 

The common causes for this problem are a break in the starter circuit's wiring, a faulty starter or a faulty solenoid. Before suspecting electrical or mechanical failures, however, ensure that the parking lever is in park and that electrical connections are clean and secure.

 

Thanks the mechanic has determined the starter is gone again. second since 2011
