We took to authorized dealer and the put on a replacement water pump to the cost of 1,657.00. they said the extended warranty that was issued to us was bankrupt, and we had no choice but to pay cash for the repairs or the would keep the truck. We paid cash for that truck and also 2300 more for the extended warranty that they say is now bankrupt procedures. So, $21,000.00 for a new truck and $2,300 for extended warranty for a total of $23,300. Plus the water pump replacement that should have been under the warranty. So we had $25,000 invested up to that point and We got the Shaft. Never again will we buy a new vehicle from General Motors
