Auto failed to start or if started failed to run with computer coordinated power production. Engine misfiring and powerless and immobile. Check engine light on. Garage said there have been several of these failures on Nissan autos and expect a recall to replace defective part failing with increasing regularity. Ipdm failure diagnostic is complete engine power failure and stop after extremely rough idling, even when accelerator engaged. The problem is without warning, instant and erratic onset with no preventative maintenance protocol. This is a part failure which will strand the driver wherever it happens until the part (ipdm) is replaced, after which the various computers on the car will perform as normal and auto functions normally. This part should be improved, recalled and reinstalled with defect free replacement to avoid further damage and stranding of other Nissan drivers. Nissan has not recalled the part as yet but the repair cost me $910 for diagnoses and replace the defective and failed ipdm on the 2006 Nissan Pathfinder and perhaps other Nissan vehicles. The records of Nissan should show the spike in orders for this part as other vehicles fail to function due to failure of the ipdm. A recall should be initiated to repair this defective essential and expensive part which cannot be maintained -just replaced when it fails.

Nissan issued an extended warranty to replace faulty radiators and transmissions affected by these faulty radiators yet did not increase the warranty by the normal 12mo 12,000 mile instead they increased it to 96months and only 80,000 miles not 96,000 miles simply because most failures happen over 80,000 miles. They also claimed this was not a safety recall. When the radiator affects the transmission and the vehicle can stall during driving. How is this not a safety issue. This is from their letter informing consumers: "in vehicles equipped with automatic transmissions, a crack in the radiator assembly might occur at higher mileages leading to internal leakage of engine coolant. While the majority of vehicles will not experience this issue, Nissan is extending the warranty as it applies to the radiator assembly to demonstrate our commitment to stand behind our products and our customers. Nissan is extending your vehicle's new vehicle limited warranty as it applies to the radiator assembly and its component parts from 36 months/36,000 miles to 96 months/80,000 miles, including damage, repairs, replacement, and related towing resulting from this issue."a crack in the radiator is caused from thermal schock. Which Nissan knew about before installing the original radiator in my vehicle. I know this because they applied for a patent on Jan 24,2006 which was published Sept 2006 therefore they knowingly installed radiators that would undergo thermal shock ie crack. See the entire publication where they are filing for a patent recognizing the existing problematic radiators: Vehicle cooling system, publication number US20060196634, application number us/11/337437, assignees Nissan motor co ltd calsonic kansei corporation, inventors sato yousuke ishikawa takayuki iwasaki mitsuru filing date 24 Jan 2006publication date 07 Sep 2006. Make Nissan replace all defects.

  • 85,900 miles
At 86,000 miles my transmission started to stutter. I took it to Nissan dealership in fairfax va and they just said I needed a new transmission for $7500. They mentioned nothing about a potential radiator problem causing this, they basically played dumb about it. If I were to have them fix it with a new transmission, I would have had the same problem all over. The service manager said I might want to "punt" on this one and let someone else deal with the problem. I decided to take it to aamco and they told me that there is a problem with this model where the radiator fails and fluid is cross-contaminated with the transmission. I paid $5000 to have this fixed. Nissan should fess up to this problem. I've been doing my research and it turns out that this problem has happened with numerous Pathfinder owners. Something needs to be done about this well known, documented issue. This type of issue could lead to a major accident if the transmission were to fail on the highway or a major personal safety issue if failure were to happen on back roads.

Nissan used bad radiators in 2005-2006 that break, leak into transmissions, and require users to purchase both a new radiator and transmission. This happened to mine, and then I found countless complaints online. Nissan knew that the radiators were faulty, but didn't perform a recall, which put a lot of cars on the road with transmission failures that are dangerous.

The contact owns a 2006 Nissan Pathfinder. The vehicle stalled without warning numerous times while driving at any speed. The service engine light illuminated after the failure occurred. The vehicle was taken to the dealer who performed a diagnostic test that located failures within the catalytic convert, the camshaft sensor, and the electronic control module. The dealer replaced all of the defective parts, but the failure was not corrected. The vehicles continued to stall without warning while driving at any speed. The vehicle was taken back to the dealer for further examination. The vehicle was not repaired. The manufacturer filed report 7134302. The failure mileage was 45,000 and current mileage was 47,000.

Pathfinder 6-cyl

  • 96,426 miles
I purchased a 2006 certified Nissan Pathfinder in 2008. I was guaranteed 100K engine and power train warranty. I currently have 96,426kmiles and the transmission gave out about 1 month ago in saline ks. I took the car to the Nissan dealer in Kansas and was told that it would be covered. However after waiting over a month for the part Nissan stated that the transmission gave out because of the transmission cooling system leaking therefore the transmission is not covered. I have contacted Nissan Corp directly and have received the same answer. This is hazardous because the transmission gave out without warning during a snow storm. Likely the car managed to coast to the side of the road. I had my car shipped back to my home in clarksville tn. And was informed by the delivery driver that the parts were in the back of my car. So now I have a car that was taken apart but not fixed with a bunch of parts in the cargo area and about $2000 in debt for a rental car and shipping the car back too clarksville. Since I have had this problem I have found out that the transmission and cooling systems have been malfunctioning since 2004.

I have a 2006 Nissan Pathfinder. I purchased it brand new at the end of 2005 and have been the only owner. Sounds like I have the same exact problem most of the people listed here have. Last week when taking in my car for its routine service I was told that both my radiator and transmission are out...they are done and I need to replace them. It is costing me approx. 5800 and I have been shocked and surprised because I had no previous obvious sign that this was going on. Not even strange sounds, signs of getting over-heated or even having the sensor light go on. I mean, if the sensor light goes on for something as simple as low air pressure in my tires, I would only assume that for something as serious as my transmission, it would light on, too. Apparently fluid from the radiator got into the transmission, that has damaged it all and needs to be replaced. My vehicle warranty expired at 75,000 miles...only 8,000 miles ago, but nothing can be done now and I have to pay. It seems to me that this is a general problem to many Nissan Pathfinders, mostly years 2005/2006. I have always taken my vehicle for service at the same dealership where I purchased it, and now this. Worse thing of it all, it seems to me that these service departments deal frequently with this issue and have done nothing about contacting Nissan's hq dept. Because it sounds like a manufactures malfunction. I cannot believe how frequent my same situation has occurred to other Nissan consumers and I strongly feel like something needs to be done. I live in los angeles county, California, and if anyone is interested in furthering some sort of investigation or legal action, please contact me.

I purchased an after-market engine cold air intake for my 2006 Nissan Pathfinder. Approximately a month after I installed the intake a piece of metal from the intake broke of and got lodged in the throttle of my vehicle during a trip to los angeles, ca. The metal piece caused my car's engine to stall the die completely on the freeway within a matter of seconds. I was able to safely get my vehicle to the side of the road. I had the vehicle towed to a mechanic in barstow, ca who removed the metal debris from the throttle. The mechanic informed me the metal had broken loose from inside the intake. When I removed the intake and examined the inside I found more pieces of metal ready to break free. The metal fragments were left hanging and cleaned up after the metal was cut and the O2 sensor fitting was welded on.

  • Automatic transmission
  • 693 miles
The contact owns a 2006 Nissan Pathfinder. Upon purchasing the vehicle, the contact noticed that the check engine light was illuminated. She was informed that the fuel gauge sensor needed to be replaced. She stated that the fuel gauge indicator needle remains on the empty symbol, even when fuel is in the vehicle. The contact took the vehicle back to the dealer two weeks later to have it repaired. The dealer informed her that the cause of failure was a short in the cluster and the part had to be ordered from puerto rico. The part arrived a week and a half later and the dealer replaced the cluster. One week later, the odometer began to display the incorrect mileage. The odometer was later repaired. Two weeks later, the vehicle began making a loud squeaking noise as soon as it was started. The contact took the vehicle back to the dealer and was informed that the cause of failure was the tension belt. The dealer replaced the belt, but later discovered that the part was defective. The belt was replaced again, but the dealer was unsure if the replacement part would be defective as well. The VIN, engine size, number of cylinders, speed, and powertrain were unknown. The current mileage was 12,566 and failure mileage was 693.
