Nissan Murano Failing Engine Mounts Will Cause Thumping in Floor
Nissan Murano Problem
Average Mileage: 89,444 mi (3,500 mi - 243,000 mi)
I have a 2007 murano that I have had a problem since it was under 36K. It has a drone in the motor when under a load at approx. 1500rpm and 40mph. You can feel a slight vibration in the drives compartment and in the pedals. I have been to 3 dealerships and it is currently at the forth for repairs. I have been told to replace the tires, exhaust and trans. fluid. nothing has fixed the problem and I have been told the the motor mounts are more than likely the problem but it is a $1500.00 guess. I do not feel that a vehicle of this price (fully loaded) should be having a problem like this with such low mileage.

Everyone... Go to Rockauto.com. Dirt cheap prices.... Motor mounts were extremley cheap as well as other parts i had to purchase. Lower right and left arm were damaged as well and they cost about a 3rd less than dealer or autozone....

I've had the exact same problems as everyone else and I'm sure they are aware of the problem but my question is, why haven't they did a recall on these things? I love my Murano but after this I will never purchase another one new or used. I love Nissians period but next I think I'll try Honda!

I noticed that when I would accellerate there was a thump noise in my front end floor board. I thought it was just my amagination since the car is only 2 years of age. I had a bad feeling and took it in to be serviced. To my surprise it was my motor mount. My engine was shifting when the car accellerates. The service person said it was ok to drive it until my appointment on Wednesday. My last 4 cars have been Nissan. I was so disappointed.

While having a rear brake job and inspection at the dealership I was told that the front motor mounts in to be replaced soon. We are having no issues with our Murano at this time. The cost quoted was $479.12. He said it needs to be repaired soon. I was checking to see how to make sure he was being truthful and after reading this web site perhaps he is telling the real deal.

When taking from a stop quickly , there was a clunk or dip. Same think happened when turning. Diagnosis: right upper motor mount torn and lower front motor mount torn. Got them replaced for $675 + taxes.
