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.

Pathfinder 6-cyl

  • miles
I was driving home from a weekend vacation in ocean city, md with 2 of my children in my 2006 Nissan Pathfinder. Approximately 45 minutes into the drive on route 1 in de, the vehicle abruptly 'jumped' and then slipped out of gear. Luckily, I was able to coast into the right lane and then pull to the side of the road. If not, we could have been hit by any vehicles that were behind us. For a brief time, I was able to get the vehicle to slowly drive in 1st gear and pull into a parking lot of a gas station/convenience store. I couldn't get it to go back into drive after that point. We then had to wait 2 1/2 hours to be picked up by my husband. The car was towed to a local shop and diagnosed as needing a new transmission. The price quoted was extremely high (probably because they knew we were out of state), so we opted to have the vehicle towed back to our town of residence to a transmission shop. The shop indicated that they have seen this problem many times in 2005-2007 Nissan Pathfinders. The radiator cracks, and the coolant leaks into the transmission, which ends up destroying the transmission. This appears to be a known defect. $6000 later, I now have a repaired Nissan Pathfinder. Nissan needs to issue a recall and fix these known issues. They also need to reimburse customers who have experienced these issues and have had to pay for the repairs out of pocket.

I was driving on I 20 hwy in atl ! I was going to pickup my kids from six flags amusement park. I was driving in the center lane, and out of the clear blue, my car cutoff, and indicated a slip light come on ! I was lucky the cars around me did allow me to pull over to the side of the road ! when I was lucky enough to pull over, I began to start my car backup, and surprisingly it did start backup. I was able to pickup my kids, and I did drive no faster than 60 miles an hour when I did take my daughter's friends home ! this surprise incident, could have taken my life easily ! thanks to other drivers being surprisingly accommodating and letting me pull off the road without my car having any power !

I bought this vehicle in June 2011 from benson Nissan in spartanburg, SC. I had no idea about the radiator/transmission problems these vehicles were having &of course it wasn't mentioned in the sale. It was already slightly past the 80,000 mile warranty (the previous owner was obviously aware of problems) for the radiator. Less than 2 weeks after purchase I told the sales person &a mechanic that the car was jerking at around 60 mph when changing gears. The mechanic blamed "bad gas? & ?ethanol? & assured me it wasn't the transmission. Less than a month later, I took it back to the dealer?S &told them the car was still jerking at 60mph &asked them about the transmission. They again told me there was not a problem with the transmission. The car continued to shake worse when shifting &I continued to call Nissan &complain. The sales person even offered to trade the car in for me, but reneged when his manager declined because I "got too good of a deal on that car &(they) couldn't trade it back." The shaking began to get worse &spread to lower gears &I accepted the fact that I was sold a lemon. Through all this, no one at the Nissan dealership mentioned the transmission or radiator problem. I found out about it only after I began to research how to repair it myself &by then all I could do was pray. Barely one year after purchase while on the way to my parent?S house with my child in the back seat, &while on a busy highway, the car stuck in 2nd gear. I barely got it to my parent"S house &endured a lot of angry drivers around me. It cost $3700 to rebuild the transmission &replace the radiator that leaked into the transmission &finally after getting it back the jerking while shifting has stopped. I should've been informed about the transmission problem at purchase or at least after complaining &Nissan needs to make good on their faulty parts before someone is really hurt.

Driving the car as I normally do and felt the transmission slipping and acting funny car lost power on hwy took to an aamco transmissions mechanic and was told that the radiator coolant leaked in to transmission. So to get it fixed had to rebuild transmission, new torque converter and new radiator. I see too many people having the same problems and Nissan dose nothing to fix the problem you call them and they brush you off. Mean wail everyone is spending any-ware from $5000 to $7000. Could this get looked in to?

Our 2006 Pathfinder had started shuttering in the transmission about a week before it just gave out on the side of the road. I took it to an independent transmission repair shop, who told me that the radiator fluid had gotten into the transmission and ruined it. I did some checking on the internet and found that I was not the only one that has had this problem. Nissan has known this was a problem and has not sent any notices or recalls. I also had another problem recently with the ECM relay, that left it on the side of the road. After research found that a recall was issued and no notice was sent out. I was thankful that Nissan replaced the relay. We have call Nissan customer service about the transmission, but I do not believe they will help due to the mileage. This should have been addressed when it was discovered with a new radiator and a complete transmission service.

The contact owns a 2006 Nissan Pathfinder. The contact stated that while driving 55 mph, the transmission failed. The vehicle was then maneuvered to the shoulder of the road. The vehicle was towed to a mechanic for an inspection. Several diagnostic codes were produced during the inspection, but they were unable to determine the failure. The manufacturer was notified and they stated that the vehicle was out of warranty. The failure mileage was 130,000.

Drove to wawa for gas and as car was idiling it over heated and check engine light came on. Got my car home and started poking around online just to find thousands of other people are experiencing the same issue. The radiator cracked and mixed with transmission fluid. Don't know if transmission is destroyed yet but time will tell. Horrible that there is no recall for this. And what a hazard I had my 3 children in car and had to tell them no baseball for them. And top it off there was no signs of any issues and car only has 59,799 miles on it.

Went to dealership and notified them of shuddering when driving in excess of 40mph and check engine light on. Was told by the service department that the transmission fluid is 'milky' as a result of coolant mixing in with automatic transmission fluid due to a crack in the radiator. Advised repairs to include a transmission cooler would be in excess of $8,000+. also advised that mileage of 91,033 voided extended warranty. (3 years, 80,000 miles) vehicle is non-operable due to total transmission failure.

  • 142,000 miles
While doing regular vehicle maintenance on my vehicle, found coolant had leaked into my transmission fluid. As a result of finding this problem, and not having the financial resources to fix it at the time, I stopped driving the vehicle on a consistent basis for around 18 months. I did the best I could to fix it by bypassing the defective transmission cooler under the radiator and flushing the transmission of contaminated fluid. Since discovering this problem I have driven approximately 6,000 miles, and now the transmission is slipping badly and when it shifts, the transmission shifts very hard. As a result of this transmission cooler failure I am now looking at being forced to replace my transmission.

Just purchased 2006 Pathfinder from local (Jeep/Dodge) dealer. Was literally driving it home from the lot when I encountered vibration and near loss of control at freeway speeds. I was able to get the vehicle home and after checking the fluids found a milky white (atf?) fluid in the coolant/radiator. The vehicle has 87500 miles and I'm beside myself right now. The dealer I purchased the vehicle from seems willing to work with me to remedy the situation but I'm not sure if they'll pay for a new transmission and radiator...? after a couple of minutes of investigation on the internet found the mass of folks dealing with the same radiator/transmission failure problem. I've got an appointment with the local Nissan dealer this week... we'll see what happens. NHTSA please help the hundreds if not thousands of Nissan owners dealing with this obvious defect!

Driving between 35-60 mph my 2006 Pathfinder was shaking as if I were on a rumble strip. It continued to worsen as the week progressed. I took it into the dealer and was told that both front and rear U-joints were loose and needed to be replaced. With only 81000 miles on my vehicle I asked if this was premature for both U-joints to fail at the same time. I was told it is considered "normal wear and tear". the cost of replacement was $1200.

At first incident, the transmission would start slipping causing a vibration while the overdrive was on, the vibration would go away when out of overdrive. Then the car would stall when you would try to take off at a stop, the car would not move until you would turn the car off and crank it again. As you would pull out into traffic the car would not go. Then even with the car out of overdrive while at speeds at 55 mph or higher the transmission would not work, you would have to let off on the accelerator and wait on the RPM's to drop and then it would go into gear again.I took the car to a local mechanic and he advised the trouble was in a solenoid in the transmission. I took the car to a transmission shop, they checked the fluid and said there was water in the transmission fluid, caused by a coolant leak from inside of radiator getting into the transmission lines causing the transmission to go bad due to coolant into the transmission.

As has been reported by many our 2006 Pathfinder has been found to have antifreeze in the transmission and we are now told it will take 4500 dollars to fix. This is no doubt a manufactures defect as there was no way to prevent this from happening or knowing for sure when it did. This SUV has been maintained by professionals and they did not catch it, I believe Nissan knew about this based on actions they have taken and now should have to repair these vehicles.

The contact owns a 2006 Nissan Pathfinder. While driving approximately 45 mph, the vehicle stalled without warning. The vehicle was taken to the dealer for diagnostic testing. The technician stated that the transmission would have to be replaced because transmission coolant had erroneously leaked into the transmission. There was a manufacturer's recall for the failure but the contact's vehicle exceeded the mileage limit for the repair. The vehicle was not repaired. The approximate failure mileage was 133,995.

Vehicle problem started with ECM/ipdm power train which stool on me. Replace for a cost of $17-1800. I paid about $1500-$1800 to get the ECM fixed and ipdm replaced. I was informed that my vehicle needed 2front converters for a cost of $2500. I contacted Nissan manufacturers and expresses my concerned. Nissan manufacturers did not want to pay attention to my concerns, but after about 3-5months of non stop complaining, Nissan manufacturers issued a recalled on the ECM and refunded my money, but refuses to fix my converters. In March 2011, I got a recalled noticed from Nissan manufacturers about a leak of coolant into transmission, so I took my vehicle to the dealership and the dealership refused to do the required inspection and claimed that my vehicle had more miles than the manufacturers required mile; and yes, my vehicle at that time was not 5years. Two weeks later my transmission went into heavy smoke with a strong rotten egg odor while I was driving. I was told that valve body inside my vehicle transmission is burned and to replace it for a cost of about $3000+, and sensor need to be replace as well and the 2 converters. Nissan gave me a bill of over $5000.

Pathfinder 6-cyl

  • 80,000 miles
Back in November 2011 (a week before thanksgiving) my car started to act up while shifting (shifting hard or not shifting). I took it to a Nissan dealer (bertera Nissan of auburn, MA) on my way to work. The mechanics there told me there was nothing wrong with my car. They never even took it for a test drive. The mileage at the time was around the 80K. In February to my local mechanic (ed's automotive, ellington ct) for routine maintenance (oil change). I asked him to check if I needed a transmission service since I was at 100K in miles. He checked the fluid and told me that the coolant was mixed with my transmission fluid and told me to take it to a dealer to see if it was covered. He informed me at that time of the service bulletin that Nissan has out. So I took it back to the same dealer that told me 4 months earlier that nothing was wrong. They gave me the info to file the claim and confirmed that I need a new transmission and radiator. I filed and waiting for a response. It took about a week. When I heard back from the customer line, they told me that they would not assist me with the issue. I called back several times to try to reach a different person to discuss this. I was never put through to anyone else. The woman on the phone told me that if I didn't like the outcome to contact the BBB and file a claim. That's great and all, but that still does not fix my car. I've only had the car for a year, I'm paying $20K for it. I was finally contacted by the Nissan corporate office after sending out several emails. Again, Nissan denied helping me. The reason I was given is because the mileage wasn't taken down by the dealership at the first visit. Really? how am I suppose to know your procedures. That does not fall on me as a customer. That falls on the dealership!
