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.

There is a leak in my radiator which as gone into my transmission rendering it inoperable. Mechanics recommend to replace the entire transmission due to this massive design flaw Nissan has been well aware of for years....updated 12/03/15 I've spoken with my Nissan dealer as well as the dealer that looked over the car when I purchased it and both said it's a massive problem and customers have no way of knowing if or when it could occur, and therefore no way of preventing it. I understand the North Carolina consumer council filed a petition back in 2012 and that the complaint volume has been tremendous on this issue. I hope the NHTSA comes to the conclusion that this part should have been recalled. I have no family vehicle now and cannot afford to pay $7500 for a new transmission, that had no issues at all until the defective radiator got a hole. Thank you

The contact owns a 2005 Nissan Pathfinder. The contact stated that while at an idle position, the vehicle shook and stalled. The vehicle was towed to the contact's residence. The contact was a certified mechanic and was able to determine that the transmission was damaged because of contamination of the engine coolant that seeped through a cracked at the line and contaminated the radiator. The entire transmission would need to be repaired. The dealer and manufacturer were both made aware of the failure. The vehicle was not repaired. The failure mileage was 142,741. Updated 02/12/16

This is the same as another complaint (# 10777718) filed through this site on 9/25. I took my truck in because of the service engine check light and the tech reported catalytic converter, heater hose vacuum & valve, power steering hose, and tire gps. We have taken the truck in for the 3rd winter season and now they are saying it cost $725 dollars to repair the issue. For 3 years we have taken it in and they flushed the system, replace a sensor, and now this" also the catalytic converter costing $1380 and power steering hose at $305. I noticed 4 recalls that we were never contacted about with the engine, and we have taken the truck in numerous times for these issues and they never mentioned the recalls. Our issue with the catalytic converter is exactly the same as the above mentioned issue filed in September. We also purchased an extended warranty, and none of this is covered. I wonder who else is having the same issue with the catalytic converter"

Issues with the transmission. Began with radiator issues. Come to find out, there has been many issues with coolant mixing into places it shouldn't. then the torque converter went out, and now the safety neutral switch and valve body. Very short engineering and problem after problem obviously known to Nissan but no recalls reported.

problem #375

  • 74,251 miles
After receiving a complimentary multi-point inspection from the local Nissan dealership, my wife told me that on the way home that the transmission seemed to not want to shift properly. Went to check transmission fluid and found that the dipstick is locked into place. Did some quick research to find out how to check fluid level and then found out about issue with Nissan Pathfinders radiators having a problem with leaking coolant into the transmission cooling system. Checked radiator and found frothing foam on the inside of the pressure cap indicating that the radiator had failed. Contacted dealership and asked them why the section of the inspection for the cooling system and transmission system were checked as "ok". did not receive an answer. Also, we were never notified by Nissan about the issue with radiator in our Nissan. The vehicle is currently parked since the dealership said it would cost up to $3000 dollars in repairs under the agreement reached. I do not understand why this was not a recall. This situation could of caused a catastrophic failure of the transmission at speed while driving or catastrophic failure of the engine because of lack of cooling causing the engine to seize up at speed while driving.

problem #371

  • 61,000 miles
The vehicle has had all sorts of issues starting with the brakes when one brake shoe totally disintegrated and evidently ruptured brake lines at around 61,000 miles. New brake replacement almost $900. Since that time (the vehicle now has 75000 miles) the transmission has continually slipped, the gas gauges and all other gauges work intermittently, and the emissions test last month showed possible catalytic converter issues (there are evidently two). When taken in for service the service technician suggested I get rid of the vehicle because it was notorious for cross contamination of coolant and transmission fluid. Continuing to drive it would eventually destroy the transmission, and even now may have permanent damage. When contacting Nissan about possible recalls and the supposed settled class action lawsuit concerning the transmission contamination, I was told I would need documentation of all service done to the vehicle to receive $800 toward the necessary $3800 repair cost just for the contamination leak. If anyone is considering purchasing this or any other Nissan product, I would avoid it at all cost.

I have submitted a previous complaint about the transmission failing as a result of a radiator leak into the transmission. The car was repaired and running fine however a new problem emerged, that is a result of the same radiator leak. My transmission control module failed on my wife while she was driving it. This is directly related to the radiator leak as there was coolant in the computer module. She was stopped at a stoplight on a busy freeway and suddenly could not move the vehicle. It created a huge safety issue for her and my sons. The repairs have now exceeded $5000.

The vehicle does not always go into gear from a starting position, or from one gear to the next. Also, it will suddenly lurch into gear. It's a consistent issue that happens every time the car is driven. I took the vehicle in for an inspection and was told it was an issue with the coolant leaking into the transmission and vice versa. I researched the issue and discovered that it had been reported to the NHTSA and is under investigation.
