Are these listed as a "manufacturer vehicle"--just curious how you got the information. I definitely would want the GMVIS report--lots of useful information. You should get it and have us all take a look.
Just took a look at CA's lemon law--besides the "serious" issues, there are two other ways to make a car a "lemon" in California:
(2) the same problem has been subject to repair four or more times by the manufacturer or its agents and the buyer has at least once directly notified the manufacturer of the need for the repair of the problem as provided in the warranty or owner's manual or (3) the vehicle is out of service because of the repair of any number of problems by the manufacturer or its agents for a cumulative total of more than 30 days since delivery of the vehicle. https://oag.ca.gov/consumers/general/cars
I can tell you from personal experience that having a low volume vehicle can make a 30-day "out-of-service" time very possible. There are sometimes just issues with getting parts, even if it's a minor problem. And the way this is read--it's cumulative, which means just a couple of repairs that took more than a couple weeks each could possibly trigger this right. An angry customer could very well have exercised this.
Either way, get the information on repairs and also make sure the dealer knows you're VERY concerned about this history--and demand a corresponding discount in price to help quell your unease.
