I bought a 2017 Cruze diesel new and I am pulling the plug on it. I informed GM that I was initiating a buyback. Why you ask. Since i bought the car it has been in the shop 13 times for check engine light with codes related to the DEF system. They changed every component in the system and some of them several times. Today is May 24 and the car has been at the dealer since Feb 24. This time it gave 3 codes one for the emissions, one for the mass air flow and one for #4 cylinder imbalance. The dealer told me that they are waiting for parts???. There is one part they said that isn't available in the country after checking all GM dealers and warehouses. I don't know what part they are talking about but the car is less than 3 years old and even though they stopped production, parts should be available. The service manager said I was not able to claim a buyback because it was only applicable for the first year, but in the state I am in I have 3 years from the date of purchase to request a buyback. Waiting to hear from GM advisor.
