Vehicle Shudder problems of the 2006 Nissan Xterra

While driving, average speed 40-50 mph the vehicle started shaking violently, rpm fluttering. Also going from park to drive, it will slam into gear. Checking the coolant, it is a milky white color.

Vehicle shudder like rolling over rumble strip. Problem is related to manufacture defect with radiator.

I was traveling to work that morning. I live on top of a mountain so I was going down a mountain. I started to hear a grinding sound between 40-60 mph. Then the vehicle began to shake. When I would slow down it began to stop. I got to work and when the technician looked at vehicle he stated the coolant had mixed with transmission fluid. I am in the car buisness so I knew that this was major damage. I called a local Nissan dealer and to my surprise learned that this is a well know issue with this vehicle. I am very upset and this could have caused a major accident being on a mountain and having the transmission go out. I have taken very good care of this vehicle and am very displeased with the service. I wrote a complaint to Nissan north America and the only reply I recieved wa to tell me about an open recall on the vehicle. Well since the vehicle can't be driven I guess that recall will have to wait. I did replace the radiator and flushed the transmission several times in hopes that it would save the transmission but so sorry to say I still have the shutter and vibration at 40 -60 mph. The extended warranty that Nissan has come up with is a laugh! most complaint I have seen the consumer has problems well after 100000 miles and why should the consumer pay anything on a defected part that caused the damage. Shame on Nissan!.

I purchased my vehicle brand new in 2007 and have had it regularly maintained since this time. I was driving down the highway at about 60 mph, when the vehicle began to shake violently. I was in fairly heavy traffic and had difficulty maintaining control of the vehicle as I struggled to pull it to the side of the road. I had it towed into my local dealership who informed me that the radiator had cracked and coolant had worked it's way into the transmission. I am being told that I need to replace the radiator and transmission which will cost me $5500 in parts and labor. In addition to this, transmissions for this vehicle are on backorder and I must wait even longer for the repairs. Of course, I have 95,000 miles on the vehicle and that means I am outside of the warranty coverage. My biggest complaint is that this problem is likely a manufacturer defect and seriously puts owners at risk of injury or even death. I wish Nissan would be more accommodating in reimbursing the repairs and warning owners about this problem in the future.

I bought a new Nissan Xterra from sloane Nissan in 2006, after 70+ miles, the car vibrates at around 40mph while shifting automatic gear (I did not know why it was vibrating). Finally aft 80+ miles, I took it to the dealer to only find out that the radiator blew the transmission. That is a shame, I just finished paying for the car and now I have to spend more money to fix it. It seems to be a very common problem with Nissan Xterra, pathfinder & frontier. The radiator is junk and needs to be recalled.
