  • 116,000 miles


At acceleration or while driving at lower speeds the transmission shudders, I am aware of a poorly settled class action lawsuit, however it does nothing to protect vehicles above 100,000 miles. The radiator is documented for cracking and leaking coolant into the transmission. This is my first vehicle purchase and I can assure you I will never purchase a Nissan product again, I realize all vehicles break down however Nissan was aware of the common problem and continued to disregard the value of their brand by neglecting to recall and repair this common failure.

Have experiences shudder while driving over last few months. On date of incident, I pulled over after one such shudder, then continued and had no torque but was able to proceed, as if lower gears were no longer working. This issue continued while accelerating after every stop light and sign. Got home (with sick child) and shut down vehicle. Tried to start 30 minutes later and would not restart. Towed to mechanic.

  • 80,000 miles
The contact owns a 2007 Nissan Pathfinder. While driving 50 mph, the vehicle shook violently. The contact released the accelerator pedal and had to accelerate again very slowly. The failure occurred multiple times. In addition, the air bag warning indicator was constantly illuminated. An independent mechanic stated that there was cross contamination with transmission fluid leaking into the radiator and coolant entering the transmission. As a result, the transmission failed. The radiator was replaced and flushed; however, the failure persisted and the radiator had to be continuously flushed of transmission fluid. Additionally, the contact asked the dealer if the vehicle was included in NHTSA campaign number: 08V690000 (air bags), but the dealer stated that the recall was nonexistent. The manufacturer was not notified. The approximate failure mileage was 80,000.

The transmission began to slip and the radiator fluid overflow cannister started to expel a purple liquid. Car was found to have a cracked transmission cooling tube in the base of the radiator and the antifreeze had mixed with the transmission fluid. Found out on line that this is a very common problem that Nissan refuses to acknowledge as a defect. Radiator replaced and cooling system flushed along with the required transmission flushing and fluid replacement. Repairs became very expensive. Only hope transmission doesn't fail next.

Transmission on the Pathfinder was very rough shifting from 3rd to 4th gear. We returned it to a dealer, who said it needed a new transmission. It seems that this has been a very common problem, and it seemed the company should have done more to remedy the problem than just hoping the newest extended warranties ran out before the cars needed repairs.

Discovered a small pool of purple liquid under front left tire of my 2007 Nissan Pathfinder in the garage yesterday. Thought that must not be good, so I started doing some research online. Behold, discovered it was most likely a radiator leak and most likely leaked into transmission as well. Took the vehicle in today, and my concerns were confirmed. Radiator replacement = $800. Transmission is working normally right now, but from what I can tell the damage may already be done and its only a matter of time before catastrophic transmission failure +$4000. The issue I have with this whole situation is Nissan is very aware of this defect, yet did not issue a recall. All they did was extend radiator/transmission warranty. This warranty does not apply to my vehicle being over 100K miles. All Nissan had to do was issue a recall, fix the defective radiator (probably a $500 fix for them) instead, they ignored it, and the customer is stuck with a $5000 fix they did not even see coming due to them not notifying us about it. I am not pleased.

I am a very loyal Nissan/Pathfinder owner. I'm on my second Pathfinder and always have my beloved 2007 serviced regularly at the puyallup Nissan dealership. Because I rely on my vehicle for work, I make sure to keep it current with all recommended services over the life of the vehicle. Until recently, ive been an extremely satisfied Pathfinder owner. Now, I am quite upset that a known defective radiator notice I received approximately a year ago, advised to do nothing if experiencing no problems, but now that I'm over the limit of 100K miles (115K), and experiencing the known radiator defect issue, I am now on the hook for the entire repair cost ($5000). I've researched the issue which can be summarized at what does the miles matter" does Nissan's obligation to their product and customer disappear after 100K miles? why didn't Nissan recommend replacing the radiators, as a preventative measure" further research of testimonials from other Nissan owners experiencing the same issue, suggests that the radiator problem seemed to typically occur after 100,000 miles anyways. So how is it that Nissan is ok with leaving their customer holding on to the (crud) end of the stick? I sure hope I am reimbursed for the hefty bill some way some day. (I've not yet pulled the trigger on having the repairs done, as I have been contemplating trading in and giving the problem back to the dealer, but how will this affect the trade in value, and if Nissan's past reputation is diminishing, why do I want to trade in for another Nissan. My passion for Pathfinders has suddenly dropped considerably...time for a new brand maybe.....:-((((( very disgruntled Pathfinder owner, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

When the car reaches speed of 45 mph, it begins to jerk and vibrate and a loud noise starts. If I press the overdrive button to turn it off, the car smoothes out. If I do not turn the overdrive off, once I lower speed or accelerate, it stops vibrating. Diagnosis from mechanic is coolant has leaked into my transmission fluid. Car should have new radiator and transmission put in.

Pathfinder 6-cyl

  • 156,000 miles
Radiator fluid mixed with my transmission fluid, making the car undriveable. At 65 mph the vehicle began to slow as the RPM's were increasing. The vehicle then slowed to only 40mph, and we barely got the car off the hwy. Then, eventhough in drive, the vehicle would not move; like it was put in neutral. Looked up issue online, and it is another known Nissan recall; but they limit the amount of miles that you can have to receive any reimbursement. Basically, I will get no relief for this known defect. I did get a recall notice but my vehicle was having no issues at that time, and now at 18 months later my vehicle is toast. I will never buy a Nissan again.
