just to add some more perspective
At work we have 7 late model Colorados
All have been taken bake to dealer within last 12 months with issues
All are under 60,000 kms
Issues include
1/ Wiring looms rubbing on firewall where enter cabin causing short circuit in computers
2/ Wheels wearing irregularly
3/ Alternaters/ battery failure
Bad Batch? The dealer has repaired all under warrantee
