Ford is not alone in this situation. My daughter bought a 2009 Nissan Murano with a V-6 engine. It had 60,000 miles. Problems started immediately. Dealer kept it 10 days, said it was a corroded cannon plug. It ran great for another 30,000 miles, did it again. Another dealer, (were she went to school) said it was a cylinder head gasket. The repair lasted 10 days, the charge was $3500. Another 30,000 miles go by, the same problem. The original dealer diagnoses cylinder head gasket failure, and admits it was the same problem they fixed originally, under warranty. I asked why they told me it was a corroded cannon plug. He said the factory was having problems with that year's head gaskets, and did not want it publicized. I called Nissan Customer Service and laid out what I knew. The nice lady told me that the same repair had been done on the engine at 30,000, 65,000, and 95,000 miles. I made the point that it was time to correct a manufacturing problem with a solution. She told me that the car was out of warranty, and Nissan had tried to correct the problem in good faith. I asked if she thought concealing a major repair was good faith. She would not give an answer.
I dug a bit further into the problem with two large engine rebuilders. I was told that they would not rebuild the Nissan V-6 from 2009. Later models had cured the problem, but the 2009 solution was never found. My daughter loved the car, but neither she nor I will ever purchase another Nissan. Regards, Clark
