After year 3 an oil pressure sensor went out, idling issue, not sure why. Dealer could never tell me why either. Since there is no fuel filter, i am wondering if there could have been something restricting the fuel flow!!!. Year 4, tensioner pulley bearing went out, Year 4.5 traded the Envoy in for a Jeep Wrangler Unlimited. Probably never buy this model again, it was transportation and cheap. Sticker was $29,500, after discounts and rebates i paid $19,500. it was a good price on a SUV to haul my kids around.
GM needs to go buy a Ford SUV and sit in their seats (very comfortable).
