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 contact owns a 2005 Nissan Pathfinder. While driving, the contact stated that the vehicle would drag or hesitate while shifting into the next gear. The dealer diagnosed that the radiator fluid was leaking into the transmission, causing it to fail. The transmission and radiator were both replaced, but the failure recurred. The manufacturer was notified and assisted with the initial repair. The failure mileage was 80,000 and the current mileage was 112,000.

Pathfinder 6-cyl

  • 106,000 miles
The vehicle had difficulty changing gears and the check engine light came on. On 8/22/11 I took the car into a Nissan repair shop and it was confirmed that due to a faulty radiator, coolant leaked into the transmission causing corrosion. I was told that I would need a new radiator and transmission at a cost of approx. $6000. I called Nissan Consumer Affairs and spoke to 2 representatives and a supervisor who stated that due to the milage on my car, they would offer no assistance with repairs. I pointed out that this is a result of well documented defects with the radiator however they stated that Nissan has no obligation to assist me as the product has not been recalled.

Pathfinder 6-cyl

  • 85,208 miles
I am a car dealer in Montana, purchased a 2005 Nissan Pathfinder at the auction with 85,000 miles for re-sale. Showed it once to a customer, it ran fine, I drove it home 8-6-11. 78 mph on cruise control on the interstate. The transmission dis-engaged, I barely recovered from hitting the medium at that speed. Turns out this is an issue that the transmission cooler leaks fluid into the trans on 90% of this model year. Even though I am a dealer...this is not right. $4500 repair. Thankfully it was not one of my customers. Nissan should re-call every one of these and make it right. I cannot believe there has not been a death from this failure. I am sure there has been many stranded travelers that may have died as a result.

I was driving along at approximately 60 mph when the Pathfinder seemed to be loosing power and it appeared the transmission was slipping. I pulled off the 4-lane; put the vehicle in park; turned the vehicle off; restarted the vehicle and continued on my trip. It initially seemed as though it was corrected; however, when I stopped for a traffic light the vehicle would rev but was slow to pull out. I was able to take the vehicle to a Nissan dealership. Later that evening I received a call that the transmission fluid appeared burnt and that the transmission would need to be replaced to the tune of approximately $6,900. The service rep told me that there was radiator fluid mixed in with the transmission fluid in the transmission. I also have reported this problem to Nissan through its website. The vehicle has approximately 149,000 miles. This is a serious problem that cause serious injuries or death if one was pulling into or out of traffic when this problem is encountered. A recall must be made for the safety of Nissan owners and the community at large who also may be impacted by this problem.

The family and I all got into the car after grocery shopping, it seemed to be a normal night except when my mother went in for reverse to get out of the parking spot the car accelerated backwards and the car took over, our mother was yelling saying ' the brakes wont work ' everybody was in such a panic the car hit two circles in the store parking lot. Luckily no one was there. We ran into the store gate which was there just in case those sort of things happen but my brother who was sitting in the passenger seat stop the car by putting it in parking.

Pathfinder 6-cyl

  • 102,000 miles
I was driving on the highway and the transmission failed. It was sudden and there was no warning. I was driving along fine and all of the sudden I had no power. I was able to pull over and get help. When I took the vehicle into a repair shop I was told the radiator leaked fluid into the transmission and ruined it. I had to pay to replace both the transmission and the radiator. I also received a letter from Nissan stating this was a known design flaw. When I asked to be reimbursed I was told I was outside of the warranty mileage. I disagree if the damage was caused by a defective part, not wear and tear and not misuse of the vehicle they should recall this on all vehicles regardless of mileage, etc. I have tried contacting Nissan several times and I have been told there is nothing they can do. The damage cost about five thousand dollars to fix and it all had to come out of my pocket. I am so disgusted with this company and the terrible way they handle their mistakes. I will never buy another vehicle from them and I have warned others to get their vehicles checked before they get stranded somewhere or possibly have an accident because of the gross negligence of Nissan.

I own a 2005 Nissan Pathfinder and at 81,500 miles began experiencing transmission vibration while traveling between 40-45 mph. During this vibration, my acceleration abilities were limited. The transmission vibration was the result of defective radiator which caused radiator fluid and transmission fluid to mix. I received a letter from Nissan informing me that the warranty on the radiator assembly of my 2005 Pathfinder is being extended because a crack in the radiator assembly might occur at higher mileages leading to internal leakage of engine coolant. the radiator and transmission have since been repaired and Nissan is unwilling to reimburse the cost of the repairs. As the radiator failure and affected transmission is a well know issue by Nissan and the Nissan consumer community, Nissan should be responsible for all costs to repair the radiator and affected components. Nissan being responsible is ever more evident by the fact that the transmission is affected, which causes intermittent acceleration issues.

Nissan Pathfinder cooler/radiator/transmission are faulty and Nissan is aware of the issue but refuses to warranty every cooler, only a percentage of them. Nissan has extended the warranty for vehicles up to 80,000 miles or 96 months. Nissan should be made to recall all cooler and cover the expenses for the ones that have had to have it fixed. Make Nissan warranty every faulty cooler.

  • 20,000 miles
The transmission in the 2005 Nissan Pathfinder slips and jerks while driving at highway speeds. The slippage can cause the vehicle to rapidly decelerate in traffic increasing the likelihood of an accident. The rapid jerking of the vehicle can cause the vehicle to loose control on its own or frighten or disorient the driver causing the driver to loose control of the vehicle.

In March 2010 we took the vehicle to a dealership for a check engine light staying on and the fuel gauge malfunctioning. The problems discovered were a fuel sending unit failure and an evap air control valve failure. Estimated repairs cost around $1300. We were told the fuel sending issue did not effect fuel delivery so we elected to wait and save up for the costly repair. On Oct. 23, 2010 while driving the power steering and brakes stiffened and the vehicle died while crossing traffic leaving a stop sign. It started rough and we proceeded to a fuel station thinking the broken fuel gauge reported fuel in an empty tank. When I attempted to fuel the vehicle it only took about 4 gallons. The tank had plenty of fuel. This stalling and dieing then happened more times in traffic causing us to barely maneuver out of the lane to safety. Each time it died it was rough to start, but started. We made a service appointment for Nov. 12, 2010 to have this looked at and get the fuel sending unit repaired under the new warranty extension (thank you Nissan!). on Nov 11, 2010 after pulling out of a parking space the vehicle died again and this time would not start. As a result of our location (no local Nissan dealership), we then had to have it towed (at our expense) 38 miles to the nearest dealer to look at it. We also had to cancel our original appointment for service at another dealership. They informed us that the new non-starting and stalling problem was a faulty ignition power distribution module (ipdm). This ipdm is a known recall issue in other 2004-06 Nissan but Pathfinder was not listed. Our new estimate to replace the ipdm so it will start and run is approximately $700. The ipdm failure almost caused multiple accidents, stalling in traffic. I can't believe that Nissan used a different ipdm in just the Pathfinder and will own-up and recall their mistake.

Radiator/transmission fluid mix the trans started shifting in and out of O/D at just over 40mph (vibrating) at about 99,000 miles. Took it to the shop and found the radiator busted and mixed with trans fluid. Had the radiator replaced and the transmission flushed twice. At a cost of $1,058 it worked fine until 103,000 miles. It just made a thump noise and the transmission started slipping so bad it barely got me home.

2005 Nissan Pathfinder. Transmission failure due to coolant contamination. Radiator had to be replaced as well as the transmission. Many other problems with car. The fuel sending unit, air conditioning/heater fan, drive shfts/universal joints, brakes. Just about everything has failed and cost me massive amounts of cash.

After transmission flush, transmission failed shortly thereafter. Replaced transmission June 2009. March 2010 had vibration problem and returned for transmission repair again. Second torque converter replaced. Within 1 week vibration issue returned. Dealer review confirmed that coolant from radiator had leaked into transmission and that radiator and transmission need to be replaced. This would be my second transmission, and third torque converter in less than a year, due to a faulty radiator used by Nissan in '05 & '06 models.

I own a 2005 Nissan Pathfinder and I have been having problems with the heat staying consistent (does not blow hot air when idle) as well a vibration when driving at certain speeds. I also begin to notice that transmission began to slip. I would stop at a red light and go to take off and would not be able to pick up speed which can be dangerous when entering the highway. I researched this online and found many others having the same problems. I took the truck to a Nissan dealership and they told me exactly what I already knew, the radiator was now no good and leaking antifreeze into the transmission which has caused both of them to be ruined and they want to charge me 5K to replace. I asked if the dealership has seen this before and it was confirmed that several of the same vehicles have been in for this very reason. He advised that Nissan has not paid for these services as the vehicles are always out of warranty on the radiator. I still have 2000 miles left on my powertrain and advised that I would be contacting Nissan for "goodwill" assistance. Nissan finally contacted me and advised that since the problem was initially caused by the radiator, they would not honor the powertrain warranty. They also advised me that since I was not considered "loyal" to Nissan as this is my first vehicle with them they could not help me. I do think it is fair to hold the consumer responsible for fixing the transmission as clearly the radiator is defective and the problem doesn't begin until after it is out of warranty. I cannot afford to pay 5K for the transmission and I shouldn't have to. If this was a rare case or caused by the consumer then, yes we should be held responsible but this is clearly a defect as all Nissan dealerships are aware of this problem. Please assist us and issue a recall for these parts as driving this vehicle is unsafe.
