Retailer failed VSI due to a defective cracked catalytic converter under warranty. Part is still in use because retailer refuses to service vehicle forcing me to operate my unsafe vehicle endangering myself and family including my then [XXX] son. Dealer confirmed defect and warranty coverage yet still refuses to address the issue. The vehicle has become notably louder as a result of the exhaust leak.
