One problem related to starter has been reported for the 2002 GMC Envoy. The most recently reported issues are listed below.
I purchased a 2002 GMC Envoy new in 2002. Early this year the starter quit working, I had it towed to the dealer, they told me the starter was bad and it would cost $625. I repaired cars for 30 years before I became handicapped, now I am unable to repair, when I did repair I put about 20 starters in for $39 for the starter and 1 hour labor.
