TL- the contact owns a 2005 Nissan Altima. The contact stated that while driving approximately 45 mph the vehicle was shaking and hesitating. The vehicle was taken to the dealer for diagnosis. The technician stated the catalytic converter had detached and caused engine damage. The engine would have to be replaced. The manufacturer was made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 183,300.
This year I am required to obtain a smog test for my 2005 Nissan Altima tha I purchased used from power Volvo in California. My car is throwing off a P0420 code which requires a replacement to the pre-catalytic converter. Per the owners manual, my car should be covered under California emissions for 15 years, 150,000. Yet when I took it to the dealer to have the converter repaired, I was informed that my car originally came from New York and California emissions did not apply and therefore not covered under the states emissions warranty. I have owned the car for 4 years and have driven it and lived in California since I purchased the car. I can't believe that a dealer could be able to get out of a repair to this pre-cat defect because the car was "first sold in New York". I have filed a claim with Nissan requesting assistance but have yet to hear back (claim #7271179). I have also started consuming oil which is not due to an outside leak and my driver's side floor board is rusting. Please help!
The contact stated the fuel system and cluster module had to be replaced with less than 800 miles on the vehicle. There was a pinging noise coming from under the mid section. The vehicle was taken to the dealership, and they stated this noise was normal. A local mechanic determined it was a broken catalytic converter. Based on complaints on a website she felt that a clamp nut may be loose. This has not been addressed by the dealership. After 90 minutes in the vehicle the contact became dizzy by what she felt may be related to the exhaust system. The transmission jerked, and hesitated in low gears. The dealership has not been able to diagnose the problem with the transmission. The front windshield defroster partially defrosts the driver's side, but did not work at on the passenger's side. The vehicle has not been seen by the dealership for the defroster.
