The car was taken into steven lust automotive and we were told that a transfer seal needed to be replaced and that GMC was aware of the issue but would only warranty the issue if the car was produced in a certain factory. Same year same model all having same issue but produced in a different plant. Now the stabililtrac warning comes on and from research on the web this is a common issue that they are aware of also but refuse to fix. This car only has 66000 miles on it. We also contacted GMC and they told us that they are aware of the problem but will not warranty it unless is was produced at a certain factory. When the stabilitrac warning was noted I was driving down the highway and the engine just shut down. I do believe this issue is due to the excessive oil leak coming from the seal. This is the second time that I have placed this complaint. When I called to confirm that I placed the complaint no one could find it.
