Owner complaint summary

There are a couple of issues causing our concerns about the car. 1. Alternator - The alternator was reported went bad after only 4 years of usage, the dealer refused to pay the fixing cost for this. Due to the failure of the alternator, the car lost all the power in the middle of the road with our entire family in the car during the night, very dangerous. The car suddenly stopped at the road with 50MPH speed limit. 2. Engine and Catalytic converter pipe - The engine light is on due to abnormal feeling of the engine power, the dealer could not fix the issue in weeks and no rental car provided and we were asked to drive the car home and waiting for order status of the parts. 3. Exhaust system failure - The dealer mentioned the welding of the connection is bad ( still under warranty ) but refused to fix it but ask the customer to pay for the replacement and labor.
