only had a car for a year no issues, started hearing a knocking noise two days later in the middle of the intersection the car throws all the lights and refuses to move. The engine gives out we take it to the dealership and they confirm that it is the rod bearing issue which is a known issue with ACURA which is currently on recall. We send the issues to ACURA and they are refusing to advocate for us for the fact that this is a KNOWN RECALL ISSUE but even though our car is not vin specific for the recall this issue that we are having is the same issue as the recall. Like it was stated earlier that there was no issues with the car before the engine blew. This is a safety concern of Acura as to why they placed the recall on these make and models in the first place. We have asked for a goodwill recall adjustment as was denied which is also not fair because again an engine does not just give out like that. We are not being taken care of by our manufacturer for a manufacture defect and we know that there is currently a class action lawsuit with Acura for the same issue we are having and they are refusing to do right by people who are purchasing these cars.
