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.

The transmission failed on my 2006 Nissan Pathfinder due to a poor engineering issue from Nissan. This problem is a very dangerous problem. Transmission can fail at anytime.

Driving down the road the transmission started slipping and quite pulling in traffic and was almost hit from rear on the interstate. Found out radiator failed and filled transmission full of coolant and caused complete failure of both systems.

The contact owns a 2006 Nissan Pathfinder. While attempting to complete a left turn, the vehicle stalled without warning. The vehicle was towed to the dealer where it was diagnosed that the radiator hose cracked and leaked fluid into the transmission, which contaminated the transmission. It was diagnosed that a component within the steering column fractured and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was 157,000.

Vehicle jerks and stalls and even cuts off during driving. I was driving on the interstate and went to change lanes and the engine just shut off. I tried to pull to the side of the road quickly but I had no engine power. I coasted to the shoulder of the road and called my husband to pick me up. I had the vehicle towed to my mechanic and he advised us that the automatic transmission fluid had contaminated the anti-freeze and vice versa and that I'd need a new transmission and radiator installed for $5500. He also added that Nissan had just lost a class action lawsuit to repair the vehicles affected but the catch is that your vehicle can not have over 100,000 miles on it. From my research in the forums, the issue does not arise until the vehicle mileage exceeds 100,000, so we're basically screwed for repairs on our Nissan with 100,001 miles or more. I'm double screwed as I have 2 2006 Nissan's. my other vehicle is currently inoperable due to atf contamination.

At first I thought my heater was the problem. I took my truck down to the dealer for inspection, and a mixture of coolant and transmission fluid was noticed. The dealer told me I was going to need a new transmission, radiator, and hoses. They said all of that would cost me $8,000.

Our 2006 Nissan Pathfinder was having issues where it would shutter heavily while trying to accelerate, the power would drop off and the car would rev high. After taking it to the local Nissan dealer, they found the cat converter bad and the plugs fouled. They fixed that and the car ran "better" but was not quite running perfect again. Several months later we were suspect of a similar issue as last time where the car would lag before shifting especially when we would step on it. So, we took it back to Nissan and this time they found the issue that thousands of people are having where the radiator cracks and leaks coolant into the transmission. After being quoted $5900 for the fix, I asked about this issue I've seen online and not until then did they look into it and see that Nissan put out an extended warranty on this matter. I still have to pay a $3000 deductible which is bs but it is better than $5900

I bought this SUV brand new back in 2006, never had major problem till now. We just found out Nissan's radiators are a huge problem they leak into the transmission and that explains why our transmission died. While I drove on the freeway the transmission slipped. Luckily the car didn't stall after I pulled in the driveway. I brought it to the repair shop they said the coolant leaked in to the transmission. They told me that I needed to have the transmission replaced because it got coolant in it and damage the inners.

Transmission needs to be replaced due to radiator fluid leaking into transmission. Nissan had an agreement to help cover costs but it only covered vehicles with less the 100K miles.

I have a Nissan Pathfinder with 88,000 miles on it. Somehow coolant leaked into my transmission causing severe damage. Nissan is telling me oh well since my warranty was up at 5yrs 60,000 miles. I've heard that this is a known problem with Nissan and that they aren't doing anything to help. Does anyone have any ideas"?" thanks!

Brought my vehicle into the local Nissan dealership in 2013 for a basic service and oil change. The complaints about the radiator/transmission cooling system were well established. There was no documented information in the service visit file on my 2006 Pathfinder to show that an inspection for this known defect was done. This brings us today where my Pathfinder currently sits at the Nissan dealership in need of a new radiator and transmission. As a result of the defect, while driving my truck started to overheat and then the transmission dropped into 1st gear while going 50 mph. While in traffic with one of my children in the car, this caused the vehicle to rapidly decelerate. So now I have to decide to pay for this repair, that is done using the same parts with no guarantee it will not happen again. This is the third serious issue that I've had with this truck.

It was on Saturday Aug 8th, while on a family week end get away, while driving in stop and go traffic in the carpool lane of the freeway, the transmission started to slip and jump a couple of times.. I was pressing the gas pedal with no movemen, I didnt know what to do, so I turned it off and back on again and put it in 44 fearing for the safety of my family that was with me, I got it to move and pulled it over to center devider. I turned it off again and took it out of 4X4 and let it set for a few minutes. We were going to call aaa, but I decided to try it again, and was able to drive away safely. That was 2 weeks ago, I have only driven it around my house and haven't had that happen again. I am hesitating taking it to the dealer because I was just there a couple of months ago replacing the timing chain tensioner. $1850
