Why this car show records until 2012

Hi, last time I did get a Dodge Charger but It comes with the Check Engine Light, So I return the car bc a mechanic told me that it need a repair of 800 dollars But the Dealer mechanic said------ Its nothing bad and an hour after check the car, said is the transmission------- So, the dealer give me my money back after a hard discussion.

Now Im very nervous, I lost the confidence in the dealers.

So, I want you guys to be my guide, Why this Hummer shows records until 2012? I mean, no maintenance records are available.

Here is the car
