Car purchased, fraud, trades

I was given a car by my father. He bought it from a guy who said he didn’t give a guarantee. Now after 2 months oil pump broke, after 1 month engine control light went on,which still glows. Supposedly lambda probe,but changed,despite that without success. Today icv examined the contract,after almost 1 year (could have annoyed me so that I didn’t do it earlier). The following,it was bought from a dealer and Ga rantie,The guarantee was not ruled out. Could you do something else? Or is it too late? 1 year is not yet around,but if you could do it retroactively, I somehow doubt it.
