Need help with OBD2 error codes on a 2012 CX-9

[borisbecker]

I am looking at buying a 2012 CX-9 GS FWD. I did an OBD2 DTC scan and got the following results (attached). I see one confirmed DTC and another 246 DTCs. Can someone help me interpret these and advise?

How many miles are on the vehicle? That's a pretty important data point.

There are plenty of codes there related to some expensive components. The cam position sensors are the biggest red light though. If they are throwing codes the issue could be timing chain, or related parts.

I have not yet reached that mileage on mine but I have heard the 3.7 can have timing chain tensioner and guide issues. Throw the potential water pump issue in and I'd be looking for a discount for the cost of the replacement of the chains and the pump (since it's all related).
