Right after purchasing this vehicle the check engine light went on. Took it back to the dealer, they power sprayed the engine, said everything was fine. A few days later, vehicle is knocking. Took it back, radiator fluid was in trans. Replaced radiator and flushed trans. Week later, same thing now worse. Car is knocking load especially after hitting 40 MPH. Sometimes it wont pass 40mph.

I am an active duty marine and have served for over 20 years. My wife and I have been the original owners of this 2006 nissan pathfinder. While I was away on business my wife called me and told me the car was acting up. Upon my return I test drove the car. The car would not acceleration after I came to a stop. Soon after the engine light turned on. I took the car to the auto shop to get it checked out and found out the coolant and transmission oil mixed. I took the car into nissan and found out this is a common problem. Nissan extended the warranty to cover this problem; but I was over the mileage and they would not be cover my vehicle. We recently paid off the car; however, now I am stuck with this ticking time bomb. The car loses acceleration very frequently. I have to turn it off and turn it back on to get it back to normal. While I am driving it, I could feel the transmission disengage. It sometime feels like I am driving over a bumpy road. It may stop working anytime. I am getting ready to deploy and I am stuck with some tough decisions. Buy a replacement car, pay a lot of money to fix this car, or drive the car until it stops working. I don't want to leave my wife and son with this problem while I am gone. Please help.

I purchased my car new with may 3-7 miles on it in 2006. I've never had a problems as I keep it serviced on time at the nissan dealership. The car started performing weirdly this past week. The noise started out as a ticking sound when I would press the accelerator and by the end of the week my car sounded like a motorcycle when I pressed the accelerator! I would even "stutter" when I what on the interstate like it was not in gear. I got two separate diagnostics, one at the dealership, one at a non-dealership mechanic who said it was the transmission!

On december 12 2013 I was driving down highway 195,speed limit was 65 miles an hour, about ten minutes on my way home I heard a knocking sound coming from my 2006 nissan pathfinder, as I pulled over on the break down lane I got out and check under the hood and saw nothing so I continue to drive I got off the highway and drove it to the dealership where I purchase the vehicle ,and they looked at the vehicle and told me it was the transmission and it was going to cost me $5400.00 to replace it and if I don't like it, I can take it to nissan dealership in dartmouth ma, which I did, and they said the same thing and that there was no recall on the transmission so there is nothing they can do for me but put me in another vehicle with monthly payments, so I took my nissan pathfinder to a mechanic business call safe guard transmission located on dartmouth street in new bedford ma, which I ended up paying 3600.00 to replace the transmission. I need to be reimburse for the amount I spent on the transmission that a recall was on, if your company refuse I will contact the attorney general.

On august 19th while traveling on the highway when I noticed what appeared to smoke coming from my engine and noticed my temperature gauge reading that it was overheating. I pulled over on the shoulder and observed, what I now know was, coolant vaporizing from my engine. At this time all the mechanics I called where wrapping up for the day, so I had it towed and taken to a local nissan service the next morning. After paying $49.95 for the inspection the service center informed me that the radiator failed mixed coolant in the transmission fluid killing my transmission as well. They gave me an estimate of $5,901, $6,373.08 after taxes, to fix the damages. I remembered being sent a notice of a radiator recall, that I was told didn't concern my vehicle when I brought it in, so I asked about it. I was told that there was a class action suit against nissan for this issue and they extended the years/mileage on the warranty and I should call their 800 number. I called the number and was told that the recall didn't effect my VIN# and that my mileage was outside of the extension. I wasn't prepared for $6k in additional expenses so I started looking around for a more affordable price. I ended up finding a shop that was able to do the work for $2,784, and during the price shopping and repairs I spent $495.72 on a rental to get around. During this ordeal I both asked the mechanic who assessed my vehicle and google the issue on the internet. Both showed that I was experiencing the same issue that my VIN wasn't supposed to be effected by, and that it was a common issue for my model. Both sources also informed me that the situation was a ticking time bomb that nothing short of coolant system work around or replacing nissan's defective radiator would stop it from occurring.

Car began to make a knocking and "whoom, whoom" sound that got louder and louder. When I merged onto the highway (on my way to an unrelated nissan service appt.) all of a sudden it felt as though I had a flat tire. Then I lost control of the car. I lost the use of my brakes and could not stop the vehicle. I managed to pull the car over to the side of the highway (on the left in the grassy median) and my left front wheel flew off my car. I still could not stop the car as my brakes had become disengaged when the wheel came loose. Mercifully my rim digging into the dirt in the median finally caused the car to come to a stop. The entire front bumper was shoved back toward the back of the car and was damaged. The driver's side door was then damaged from the front bumper scraping against it when the door is opened and closed.
