Overall Excellent. Excellent communication and service. The electrical issue is apparently a common one to GM vehicles(battery cables internal corrosion or break) and should be a addressed as a manufacturing defect (sub standard materials by supplier) and not cost the consumer of these products another $594 to repair. The issue can be found easily on YouTube and it was mentioned that about one vehicle per week is repaired for this malfunction at this location. GM should stand up and address this problem as a safety defect. I will be reporting this to GM and the Safety Institute.
