general problems of the 2007 Nissan Xterra - part 2

Internal leakage of engine coolant in to transmission.

Radiator leaked into transmission just after 100,000 miles. So why didn't Nissan tell us this was going to happen?.

The radiator leaked and the coolant went int to the transmission and now has totally screwed up the transmission to the point of having to replace it and the radiator. Nissan knows about this problem and will not make a recall on either parts which is completely wrong.

At varying speeds above 45mph the vehicle will shudder as if you were driving on a rumble strip. This can be startling as there is no indication of when or where it will occur. When the radiator failed our mechanic informed us that the transmission was destroyed because of design of the radiator and transmission cooling lines, which allowed coolant to seep into the transmission fluid thus destroying the transmission. .

I took my Nissan Xterra 2007 into boulder Nissan in October 2013. At the time, it had under 100,000 miles. Upon examination of the car for lack of heat, they said they flushed it and eventually I would have to replace the radiator. They did not tell me that there was a class action lawsuit against Nissan for defective parts leaking coolant into the transmission. I returned to Nissan in Jan. 2015 for the same problem and was hit with a bill for $5,200 to replace the radiator, transmission, timing chain and termostat.

The airbag lite began flashing on the dashboard. Took vehicle to the dealership and the only fix action was to begin replacing parts that Nissan recommended until it was fixed. No exact fix was given only the following: visually check wiring harness for connection and damage. All ok. Next step in procedure is to replace driver's airbag module. Subsequent procedures are to replace spiral cable, then diagnostic unit, and related harness. These are all costly steps and the parts being replaced may not be bad. The dealership couldn't determine exactly which portion was failing. In conclusion: the fix action was being replacing parts (extremely costly) until the problem is fixed. Computer code: b1054 (driver airbag module open).

In January of 2013, my car was towed to the kraft Nissan in tallahassee, florida and there I learn that my computer/brain that makes my car function needed to be replace. However, I was told that my car could be at the dealership approximately 6 months or longer because the part is on back order. The part could not be found anywhere in the state of florida or in the united states. I was told by the dealership service dept that the part needed to be reproduce. I inquired if this part was a deflect issue or a national campaign for deflected car parts, and was told no. I paid approximately 1800 dollars for the repair bill. While my car was in the shop, I received a letter that explained the coolant fluid in the radiator can become contamidated with the transmission fluid and cause the transmission failure. I was having a issue with my transmission; however, after the car was repaired I requested that someone from the service dept test drive the car and indeed they drive it and stated they heard nothing. Later, I requested it be driven by a mechanic; therefore we went for a drive and indeed I was told it was transmission problem, but it will cost me 7500 dollars for a new transmission because they are not honoring any letter I received according to the owners of kraft after showing the letter as proof. As of today, I was told the computer /brain was a defected part and Nissan should have replaced the deflected part along with the transmission; today my car is at Nissan for an oil change and still to this date I am being told that they are not aware of any national campign for the transmission issues I am having even though they have confirmed today that the fluids are contamidated. Service rep quote me a extended warrant I can purchase for 3000 dollars since my car now have 103000 miles prior to it had approx 95000. I need help with this issue.

The radiator fluid and transmission fluid have some how mixed together cause damage to both my radiator and transmission. I purchase my Xterra brand new in 2007 and kept up with the maintenance. I have read several articles and even received a letter about a class action lawsuit. But at the time no symptoms were showing on my vehicle. So upset that this is not a recall!!! I am a single mom and this was my only means of transportation. Now it just sits in my yard. Frustrating!!!.
