We found out the problem was the catalytic converters were broken apart and got sucked up in the engine and ruined the bores on the cylinders thus the engine has failed. My problem is that Serramonte Nissan in Colma, Ca, knew the problem but had us drive the car around for another week or so and then bring it back to tell us the engine failed and needs to be replaced with a new or used engine for a whopping $13,000 price tag, and couldn't or wouldn't tell us what caused the failure, so I took it to an expert mechanic in Millbrae who did check it thoroughly and said the engine had failed due to the catalytic converters breaking apart and getting sucked into the engine and ruining the bores, therefore no power to drive up hills and going through a quart of oil every 250-300 miles. We wrote a letter to Mr. Charles Goshen and Mr. Colin Dodge of the corporate offices of nissan in Franklin, Tenn. (thats--- One Nissan Way, Franklin, Tn. 37067) and at first they wanted to talk to our Expert mechanic and a week later called and said they will only need the information from their mechanics and don't need to talk to my expert mechanic. ( I wondered why?) So a week later their representative called and said after assessing all the information, they decided that We were over the 100,000 mile warranty and they was no call for them to do anything for us. All we were seeking was to show some corporate fairness and help pay 50/50 or whatever and that would show us that Nissan was a good Corporation to do business with. Well, thanks a bunch Nissan. DON'T BUY NISSAN MURANOS, unless you want to throw your money away. Believe me, as I am not the only Murano with this problem, check out other websites for yourself and don't believe the consumer reports magazine article on the murano either, it's misleading.

I had the catalytic converter replaced on my '04 Nissan Murano. The invoice says the labor is warranted for 12 months, but products are sold "as-is". Well, 18 months later when returning from an out of town trip, the engine fails. The car is towed to the nearest Nissan, not the one who replaced the CC. They discover that catalytic converter debris got into the system and ruined the engine. Repair estimates through Nissan run $8,700 to $10,000. Nissan will take no responsibility for the repair, even partially. I went up the ladder with Nissan to no avail. I am currently waiting for a used engine to be installed through an auto shop with a limited warranty for less that Nissan quoted. Besides the engine replacement I am faced with extensive towing charges and car rental. Nissan should put my future business and my friends, family and anyone else 's business first... before trying to make a profit from their negligence.
