Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

My son bought me the 2006 Nissan Pathfinder on March 8. the check engine light and tps lights were on the day we got it, I also could smell antifreeze constantly. Took to mechanic to check. He said engine coolant was leaking intotransmission fluid and that Nissan was having alot of troubles with this. He said it could cost thousands dollars to fix. My vehicle has alittle over 73,500 miles on it and I cannot afford a huge repair bill. My son is worried about my safety. Can you point me in the right direction in regrds to this please! thanks!

While driving on interstate 25 in South denver, my Pathfinder began to sputter and stall. The engine started to overheat as I pulled into a service station about two miles away. I had it towed to christian brothers auto in parker Colorado. A radiator part blew, the engine overheated and was destroyed. The steam from the plastic radiator part also damaged the main computer. It was close to $10,000 for all repairs related to the radiator part failure. Approximately 8,000 miles later, my daughter and I were driving on I-70 near the vail, Colorado exit, and the Pathfinder started to jerk violently on the highway going 65mph. I was able to pull over to the side of the road. Scary experience for us both. This happened today, 03/24/2016. Smoke was coming from under the car. I had it towed to avon auto in avon Colorado. They said the transmission is damaged, but they did not have time to look into it further. Please call or email me with further questions. 303-726-6211 or L.fab@comcast.net

The contact owns a 2006 Nissan Pathfinder. The contact stated that while driving at 65 mph, the vehicle decelerated independently as the check engine warning light illuminated. The failure recurred three times. The vehicle was taken to the dealer where it was diagnosed that coolant from the radiator leaked into the transmission which caused the transmission to be severely corroded. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 113,000.

Vehicle is currently showing symptoms of the bad timing chain/tensioner issue reported by many other consumers. The repair will be expensive for a component that should last the life of the vehicle. Should the component fail and result in catostrophic damage while driving, this will result in immediate loss of power steering and potentially cause vehicle instability and loss of control

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.

My cars radiator cracked and leaked into the transmission. The mix of coolant and transmission fluid damaged the transmission and quite possibly damaged my engine. Nissan knows about the radiator because they extended the warranty on it. The repairs for this incident are high the Nissan dealer I took it to quoted me $4,591.43 to replace the transmission and the radiator and that is with the warranty they claim they have on it. The dealer also told me any other damage caused by this faulty radiator would not be covered and I would have to pay for the repairs to any other components as well they told they me might be an additional $2,000 so nearly $7,000. I had know choice but sell the car off as scrap as the repairs would cost more than the car itself. A failure of all these parts at once is a safety hazard to everyone.

I backed out of my driveway onto the main road and went to put the vehicle into drive and it would not go into drive. When I got it to the repair shop they said that the radiator had leaked into the transmission and caused it to ruin the transmission.

Radiator fluid has leaked into the transmission causing it to fail. The dealership has issued a fix where the radiator coolant is bypassed from the transmission but then that has not helped. The fix was for $500+ the repairs for the transmission are at $4700/- now. This is ridiculous the amount of repairs is more than the cost of the vehicle now.

Purchased vehicle from car lot Feb. 28, 2015. Drove this vehicle 5 times and the coolant leaked. Flushed system notice there was stop leak in radiator. Now my transmission slips and truck shakes during acceleration. This was a previous issue before I bought the vehicle because the shaking occurred when driving home. I thought this was just the tires needing to be balanced, but after research I know that it was from the coolant previously leaking into the transmission, and now I am left to deal with it.

The transmission started to slip, which needed to be taken out of overdrive from time to time. After a few months the transmission gave out completely on the highway. It will rev up, but will not drive. Apparently they are famous for the gasket leaking engine coolant with the oil. They should have all been recalled.

Check engine light indicated a problem. After review by a Nissan dealer, there is a crack in the radiator assembly that will cause fluid to leak into the transmission, rendering the vehicle inoperable. Nissan knows about this issue and a class action lawsuit was brought against Nissan. A settlement was made giving only an extended warranty, not a recall. Data shows that it breaks on most cars after the so-called extended warranty time. Leaving most with no help from Nissan to fix this issue. This should have been a safety issue not a money issue.

Pathfinder 6-cyl

  • 76,000 miles
When I purchased my 2006 Nissan Pathfinder from a dealer in 2012. Vehicle was inspected and deemed safe to drive. I noticed my tire pressure sensor stayed on all the time. Even after filling to the recommended psi. Didn't think much of it. Went on to drive the vehicle with no issues until the next year when I would get this shaking and rumble at about 2500 RPM. Took it to a local mechanic and he couldn't find anything wrong except for needing new brake pads and engine tune up. Had that done but still my car continued to rumble when I would accelerate. It was intermittent on and off until it got so bad that I had to pull over and let my engine cool before it would do it again. Recently I took it to a different mechanic and had them look at it. She ran a test on the computer and the car gave codes that linked back to the transfer case. She then had it looked at by her transmission expert and he discovered coolant and fluid inside the transmission. Only then was it linked to all other occurrences that fall back on Nissan. I read online that there is a class action lawsuit against Nissan for failing radiators and transmissions. It was never brought to my attention when purchasing the vehicle even though this was during the height of the dispute. With it being out of date for any coverages under the lawsuit. I'm now left without a vehicle and a hefty $3,600 repair bill that should have never been there to begin with. I hope Nissan has a plan to fix this issue without the consumer paying out of pocket. If not I will be pursuing a case against the dealer for selling me a car that is unsafe to drive.
