One problem related to starter has been reported for the 2007 GMC Envoy. The most recently reported issues are listed below.
Window power module caught fire, shut down engine, stranding us. Recall replaced the module but GMC will not address the fact that the high current draw never blew a fuse first to prevent the fire and not shut down the engine. Car started up and we started driving when smoke came out of door and engine stopped. Calls and e-mails to GMC have not been answered other than the basic recall to replace the module then later added sealer on 2nd recall. No electrical fixes. Electrical issue killed my remote engine starter but they refuse to reprogram or replace as it was an after market remote starter that came with the car. . Their electrical problem killed it, then they should be responsible and replace it.
