Can anyone relate or has anyone ever heard of their OBD port not working? I bought my 2005 G6 (base model) back in 2017. Now she’s got 220000mi on and really just needs shocks & struts... The port has never worked though, been to multiple dealerships.... They want to keep the car and figure it out but I’ve always said no- would rather diy any of the work- thank goodness every problem hasn’t really needed the obd (atleast I don’t think), but the check engine Has been on ever since & I would like to clear the code or figure out if there is still an actual problem...
