I have reviewed many many postings on the website Edmunds and I have a similar problem to them... my AC system no longer works and I'm being told that the evaporator coil will need to be replaced. I currently sit around 110,000kms. It seems to me that from the number of issues and complaints there should have been a recall, but there's nothing. This is not a mechanical system that is affected by number of kilometers driven and this is clearly a defective coil.
GM won't even have the conversation with me about coverage. They want me to pay for the repair at a GM dealer and they will then review the case. AKA: We are going to get boatloads of money from you and then leave you high and dry.
Would I buy GM/Buick again? *** NO.
