On 11/10/2018 while driving on the freeway with no warning light my 2006 Nissan starts to lose power!!! I was able to get off the freeway and pull into a gas station to call aaa to tow it to a mechanic. The mechanic told me the transmission has coolent in it and the transmission will need I be rebuilt or replaced with a rebuilt transmission. He said there was a crack in the coolent hose that was a manufacture defect. I never got any warning light until after the transmission failed.

The contact owns a 2006 Nissan Frontier. While the vehicle was idling, the transmission failed and the vehicle could not be moved. The vehicle was not taken to a dealer to be diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 128,000.

- Fairfield, CA, USA

Due to design flaw resulting in mixing of transmission fluid and radiator fluid, transmission was destroyed and had to be replaced. Vehicle was in motion on a city street at approximately 45 mph whenever failure occurred. I have since been made aware that this is a common issue with many Nissan vehicles with similar systems. Documentation of transmission replacement is not currently in my possession, however if necessary, all documentation can be obtained from transmission repair facility.

Apparently coolant mixed into my transmission and it is now slipping. And repair will cost $4500 or more. I heard a slight clunk when driving then it started to slip.

- Clearwater, FL, USA

The contact owns a 2006 Nissan Frontier. The contact stated that the vehicle slowly reduced speed and came to a complete stop several times without warning. The dealer (robert woodall Nissan, 132 union St, danville, va 24540, (434) 797-1411) replaced the transmission; however, the failure continued. The vehicle was taken back to the dealer who only inspected the vehicle and was unable to determine if the failure was electrical, engine, or power train related. The contact was uncertain if the vehicle was included in NHTSA campaign number: 1V0517000 (engine and engine cooling). The manufacturer was notified of the failures. The approximate failure mileage was 108,172.

I own a 2006 Nissan Frontier and after doing research I found the article about several recalls for 2005-2010 models. The persons involved reported the same symptoms we are experiencing such as transmission fluid leaking into the radiator coolant spontaneously and now transmission failure while towing a pop up camper that is 3200 lbs which is within the towing range reportedlyfor this vehicle. I got an extended warranty and they report they will only cover up to $1900 and my mechanic states the total costs are $4800. I am very concerned my vehicle is doing the same. Can anyone help us?

I just had to replace my transmission due to a recall. Oil and water in the transmission and radiator. I did not own the truck at the time of the recall.. how can I get reimbursed "?" this is terrible!!

Transmission shudders when shifting from drive to overdrive. Around 40-45mph shudder can be felt from transmission vibration. Had the driveshaft replaced ($1400) but the shudder is still present.

While driving truck on highway it occasionally felt like I was driving over rumble strips.

- Lancaster, PA, USA

The evidence of engine and power transfer evidently progressed over of days and regressed within a matter of hours, then minutes to the point where engine would barely start and obviously barely propel the truck over 10 mph w/engine dying out regardless of throttle or automatic shift position. I limped the vehicle to the nearest respected and qualified tech bob wells -total car care. This is the second time Nissan's lack of "due diligence" left customer down, all within a year or so. A frustrating, time consuming, and costly experience.

Having major issues. Noticed a recall but it was already settled. What can I do? radiator affecting the transmission.

- Benton, KY, USA

I have a apparently common problem which is radiator transmission cross contamination apparently with Nissan Frontiers and xterras from about 05-2010 and the problem is they used a radiator with a built in transmission cooler but there's a seal or area where it fails and the two fluids mix resulting in a strawberry milkshake appearance and when this happens the transmission will likely fail at any point I've personally had problems that were intermittent over the last few weeks with trouble shifting and a shuddering/rumbling which occurs while driving in all weather and road conditions plus is very noticeable while going from a stop to start moving turns out to be radiator fluid leaking into the transmission my truck has 99,000 miles on it and has started having problems just now which according to other accounts on multiple forums about this particular problem is a little later than most but I have a short commute to work and have another car I use. So perhaps it was that. But the issues are getting worse and it's a shame that the company knew of the problem and did nothing to remedy it. Especially as it affects many years and models of cars

Trans. Went out due to radatior leaking into it, went out while driving

Transmission tcm fried by coolant

- Pahoa, HI, USA

Radiator/coolant has mixed into transmission fluid causing transmission failure.

- Rosendale, NY, USA

2006 Nissan Frontier - a defect that permits cross-contamination of engine coolant and transmission fluid, ultimately causing the radiator and transmission to need substantial repairs or fail entirely. The truck was in motion on a highway. When accelerating the transmission did not downshift - it felt as if the transmission went into neutral.

- Chicago, IL, USA

Bought a 2006 Frontier a year ago, I was unaware of the major defect they were having with the radiator cracking and mixing coolant with tranny fluid. Now my transmission is shot with no warning and I'll be out 4/5K !! it went out as I was trying to turn left and on coming traffic was coming at me. I could not accelerate as obviously without a transmission your car wont go into gear, just a sitting duck with oncoming traffic baring down. Thankfully the people speeding towards me seen me before I was smashed into and possibly killed.

The contact owns a 2006 Nissan Frontier. While driving 25 mph, the vehicle failed to accelerate without warning. In addition, the vehicle slowed down and the contact was able to drive back home. The local dealer was not contacted or made aware of the failure. The vehicle was diagnosed by an independent mechanic who diagnosed that the radiator fluid spilled into the transmission. The radiator was replaced; however, the radiator fluid contaminated the transmission and fluid, which caused the transmission to fail. The vehicle was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer stated that the vehicle was not included in a recall and did not offer any additional assistance. The failure mileage was approximately 89,000.

- Guilford, CT, USA

Transmission failure caused by leaking fluid cooler in radiator at 114000 miles. 8000 dollar repair estimate is over trade in cost of vehicle. This caused truck to stall on freeway, endangering occupants.
