simple state inspection ends up with hundreds of dollars. 1, I was told my transmission has an issue and my car will not pass state inspection. They need at least 3 days to fix. But it is under warranty. I was told I can also rent cars and GMC will do reimbursement. 2, On the same day, I was told I need to change batteries and my transmission issue was related to the battery. I spent more than $300 to change the battery. By the way, they also asked me to change oil, but this is what I know that is not related to my car inspection, so I declined. 3, Then the transmission issue is gone. (Of course it will be gone, my transmission has no issues at the very beginning) and I got my car returned and batteries changed on the second day. I have no reimbursement for rental cars because my car just changed batteries. Then I realized lots of similar red-flag patterns in dealerships: customers are warned by a severe issue in the first place and then after a change of a maintenance part (such as battery, engine oil, filters ), all severe problems are gone! But at the same time, the customer's trust is gone as well.
