The good news is you will be happier when you get your car back!I brought my car in today to the dealer. Diagnostics showed both rear actuators failed (which I expected) and they will be covered under the extended warranty. Dealer also agreed to do the software update for the backfire/pop from the exhaust - also covered.
The bad news is that they won't have the parts in until Monday so I am stuck in a loaner over the weekend. The worse news is that the loaner is a base-model Malibu LT
