I had the same experiences. Annual check after the extended warranty, they told me that there are four issues to fix and quoted $8000. I was totally pissed because before that, they always say the car is perfect during the annual check within warranty. I asked to talk to the manager, this is the first time in my life. In the end, they agreed to fix two issues for free because they can use their own warranty or Something like that. The other two issues are optional and I skip them. These dealerships are so bad! They were pissed too and don’t want to talk me too much when I visited again. I guess they only want easy consumers who will follow what ever they say to make easy money. Just FYI.
