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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2005-2007 Pathfinder appears to have a widespread defect where coolant leaks into the transmission, causing transmission failure around 90,000 miles. Repair costs are typically upwards of $3,500.

According to the New York Times & a class action lawsuit, the defect actually extends through 2010 model year. More info here.

  • 70,000 miles


At almost 70,000 miles, I started getting a vibration when accelerating at or above 40 mph. I was told by the Nissan dealership that it was coolant intermixed in the radiator and transmission and they needed to be replaced at a cost of $6800. Nissan knew about this problem back in 2007 and didn't notify owners. Not happy!

2005 Nissan Pathfinder 92,000, vehicle won't start and had it towed, was told it was due to the radiator leaking into the transmission. After having spent $800 @ vadan Nissan, because my car would jerks and stop whilst driving, was told it was a coil problem, and a sensor issue, nothing was ever said to me about this huge problem the 2005 to 2010 Pathfinders are having, totally disgusted with Nissan.

Purchased a used 2005 Nissan Pathfinder. Had the vehicle about 2 years. Driving home one day the vehicle started to loose power as the RPM's started to spike. We had to pull off the road in a very unsafe spot because the car could no longer move. There were no warning signs of the transmission failing. We had the vehicle towed. With a quick glance into the coolant tank, seems to have a mixture of coolant and transmission fluid. Repair cost are estimated from 2500 - 5,000+. something needs to be done about this problem.

Our 2005 Pathfinder lost all power while driving on a local highway in our town to take our daughter to school. It has an automatic transmission and would not change out of first gear. We live up on a slight hill, and it honestly felt like I was pulling a semi behind my vehicle just to get it back home without requiring a tow. Needless to say we had to keep both of our children home from school that day because this is the only vehicle we own. It angers me that Nissan refuses to make a recall on this issue!! this transmission issue has caused us to be without a vehicle for almost a month now!! it's not always easy to find people that are willing to help you out long term!! this is a huge inconvenience to our family, & we don't have the money to pay out of pocket to get this fixed. A local mechanic near where we live said he has seen this issue tons of times, and has fixed numerous amounts of Nissan vehicles due to the crack that causes the antifreeze & transmission fluids to combine and mess up everything in the transmission over time. With this being an issue on Nissan's part, I feel that they should pay to have the problem resolved!!! my husband is out of work due to an injury and will be out for an undetermined amount of time. I work part time at a local bbq restaurant in our town, and don't bring home very much each week. I pray the corporation will do the right thing and finally recall all the vehicles affected by this. $3500 dollars is the best we can find & when it gets fixed, the person we have spoke with said they will bypass the radiator when the transmission gets reinstalled making sure we never have this problem ever again!!!! sadly we don't have the money for the repairs or I would not be making this complaint. If anyone knows of any information that I don't know of please let me know!!! I am desperate to get my vehicle back!!! we have no one to help. Thx

8/31/2016 - check engine light came on during normal driving, I brought it to my local mechanic for inspection which showed the transmission has failed. This is due to the radiator and transmission intermix problem is how Nissan notes it and validated by my call to the local Nissan dealer. The car is outside the Nissan extended warranty period for this issue which is 10 years but well under the 100,000 miles as it has 80K miles at time of event. Nissan is unable to offer any financial assistance so the out of pocket cost to repair ($5-$6K) makes it not worth the repair so I'm stuck with a car that to date I have maintained very well. There was not warning signs and I am sure this problem has been going on for some time as it does not happen overnight. Very disappointing that Nissan does not take ownership of the problem that has plagued hundreds of Nissan Pathfinder owners.

The contact owns a 2005 Nissan Pathfinder. The contact stated that the radiator failed and caused coolant to penetrate the transmission. The contact stated that the vehicle was taken to the dealer to have the manufacturer warranted radiator replacement performed; however, the repair did not correct the failure. The radiator coolant penetrated the transmission and caused the engine to overheat. The vehicle was taken to the dealer where it was diagnosed that the radiator and the transmission needed to be replaced. The manufacturer was notified. The approximate failure mileage was 89,000.

Coolant and transmission fluid are mixing! the transmission is starting to skip and the coolant is milky/ creamy looking and I added 3 quarts transmission fluid 7days ago and now have to add more. The coolant is being pushed out of the overflow do to the transmission fluid and coolant mixing together.
