My truck stopped in the middle of the freeway and when it was taken tothe mechanic it was collant in the transmission. Not onky do ineed to replace the transmission but also the radiator. There wereno signs of this issue or any warnings.

Radiator leaking fluid into transmission . Notices slight shutter at high speed, approximately 65 mph, in the transmission. Vehicle was checked by dealer at 89,000 miles without any issue at that time . Dealer would not replace radiator due to no problem at that time. Vehicle is at 112000 and now radiator fails. Nissan would not cover due to out of extended warranty. Faulty designed system and potential safety hazard in my opinion. Vehicle at my independent mechanic for new radiator and transmission flush out to see if it will fix problem. Major expense for poor design passed onto customer. I will not spend any more money with Nissan.

The contact owns a 2005 Nissan Frontier. While driving approximately 35 mph, the vehicle stalled when the contact attempted to slow down. The vehicle started normally after a few minutes.

Radiator and transmission failure due to coolant leaking into the transmission. This poses a significant safety issue when I lose power on a busy interstate. The transmission loses power when trying to upshift. Inspection completed via an authorized Nissan dealership. Efforts to rectify with Nissan have failed. This issue has been known for quite some time and is marked as an open NHTSA investigation.

When entering hwy 17 (70 mph speed limit) I pressed the gas pedal to the floor to enter oncoming traffic. Instead of increasing speed the truck stalled. I pulled onto the right side emergency lane in order to prevent traffic from running over my vehicle. I placed the transmission in park and it seemed to smooth out . Motor was running with excess rpm's and transmission was slipping. This was a near accident. I could hear cars behind placing on brakes and blowing horn. When returning home was told by Nissan dealership radiator cooler and transmission had to be replaced due to faulty lines. Nissan should have recalled this problem.

Entering 4 lane highway with 70 mph traffic. Kicked Frontier into passing gear to enter ongoing traffic. Frontier stalled and slowed instead of increasing speed. Transmission slippage and jerking caused motor to increase rpms. I had to move my truck over to right of paved lane and onto pulloff area in order to prevent accident. I was told at the Nissan dealership that I had transmission damage due to radiator fluid leaking into transmission . It cost me $2500 to repair a problem that could have cost lives. I understand this was a problem that was not recalled by Nissan.

The contact owns a 2007 Nissan Frontier. While the vehicle was being serviced for an oil change, the contact was informed of a leak in the radiator. The vehicle was taken to the dealer where it was diagnosed that the radiator was defective and was leaking fluid into the transmission. The vehicle was repaired. The manufacturer was made aware of the issue. The failure mileage was approximately 109,000.

According to the mechanic, the transmission coolant reservoir (which is connected to the radiator) collapsed causing water, antifreeze and transmission fluid to mix. These fluids then made their way into the radiator, transmission and coolant reservoir. This, in turn, caused extensive damage to my transmission. My transmission then required replacement/rebuild. The first possible sign of the problem was rough automatic shifting of the vehicle. I then noticed a leak of transmission fluid from the front passenger side of the vehicle (which was parked in my driveway). This was followed by a loss of power/drivability.

Transmission failed due to coolant intermixing with transmission fluid. This is the second time this vehicle has had catastrophic transmission failure due to a crack in the cooling system. First time was just over the warranty so I was forced to pay a $2500 copay. The vihicle started showing signs of a secondary failure just prior to 100000 miles and when I brought it to the dealer they lied to me and said there was just residual oil in the radiator from the first failure. . . Now I am past any warranty copay and the transmission is failing at just 100500 miles. That is just two years (less than 18000 miles) after they replaced the radiator and transmission. This is unacceptable that consumers are being forced to pay for a known issue of poor engineering especially when it was supposedly fixed by the dealer with Nissan parts. They have obviously not fixed the problem but just replaced with another defective part. On top of that they denied there was a problem to so I would continue to drive the vehicle until it was past the extended warranty (from 2012 class action lawsuit). While there was no accident in either indecent there was a near collision the first time as I was in the middle of a busy intersection and the second there was traffic behind me that had to avoid rear-ending me as the vehicle stopped, this is a dangerous defect that could result in injury or death.

The contact owns a 2007 Nissan Frontier. While driving 30 mph, there was an odor emitted into the vents and the contact noticed smoke under the hood. The contact coasted over to the side of the road and noticed oil and antifreeze fluid spilling from the reserve tank onto the transmission. The vehicle was taken to the dealer where it was diagnosed that the spill caused the transmission and radiator to fail. Both the radiator and transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The VIN was unknown. The approximate failure mileage was 94,000.

In 2013 I received a notice of class action about a Nissan vehicles related to possible radiator fluid leak into the transmission due a defect that permits cross-contamination of engine coolant and transmission fluid. It did not include vehicles before it happens. In 2013, I went to a authorized Nissan dealer to check if my radiator can be affected but they told me that in that moment the radiator was working well without given me the option of replacing it to prevent damages. At the time I was under the warranty limits, less than 10 years and less than 100,000 miles. Now in February 13, 2016 my vehicle began to have problems to move , had a harsh shift , it slowed down and did not drive at times. I clearly saw a transmission problem. I called united Nissan service for a diagnose . They check my vehicle and told me that my radiator leaked fluid into the transmission due the radiator defect. I couldn't understand why this class action did not include vehicles that will face this damage in a future . It did not include prevention of damages. Nissan did not released a recall for the faulty radiator. I know I am now outside the warranty limits, but at the time when I visited Nissan service to prevent this no one provided my help or information that would help in prevent such damage. The price for a new transmission is 6,000 dlls. The total cost of repair all goes up 9,000 dlls. Also I received a rude customer service by the service agents of Nissan service . Now I have to cover these costs by myself. My son was driven the vehicle when this happen. The good thing is that the failure occurred while he was driven on the freeway making it so dangerous. What will happen with people like us? the legal case was closed in 2012 but Nissan still having vehicles suffering this this damage . This is a negligence that pass the financial burden to consumers.

While driving down the highway at 60 mph, my 2006 Nissan Frontier suddenly was running very rough, it decelerated and I only had low gear enough to barely make it off the hwy and out of the way of high speed traffic. No dash/idiot lights came on identifying any problems, there was no warning at all. Truck was towed to Nissan dealership who said the transmission, and radiator, and thermostat all needed to be replaced!! they charged us $5,500. This truck only had 135,000 miles, and was kept in great condition, at time of it's failure. Nissan should be ashamed of making the consumer bear the cost of Nissan's faulty parts!! they are flat out lucky if no one's been injured, or killed due to this failure! had I been on the interstate as planned the very next day, in this truck, I wonder if I'd be here today. There should be no question or hesitation that this "transmission failure" is a safety issue and needs to be a full fledged recall. And we should not have to foot the bill for Nissan's screw-ups with our hard earned money. It is simply wrong.

About 3 weeks ago my truck was not shifting correctly I take to the dealer and they found a code p0717 for a turbine revolution sensor. They found there to be water being pumped into the transmission. Apparently the radiator leaks water into the transmission.

Cross contamination of coolant and transmission fluid due to factory defect in radiator. Began with no heat suddenly in the middle of January. No check engine light to warn of issue. Changed out the thermonstat and noticed the strawberry foamy liquid in the radiator then search 2006 Nissan transmission problems on line. Vehicle also stops and starts very, very, slowly in intersections, on ramps.

Tl- the contact owns a 2006 Nissan Frontier. The contact stated that the vehicle shifted out of gear independently which resulted into deceleration of the vehicle and stalled. During the failure the check engine soon light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the vehicle's radiator coolant tank had leaked fluid onto the transmission and they needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 154,000. Kh.

The vehicle has 86,700 miles, I always took care of it, changing oil at 3000 mile intervals, never towed with it, etc. , etc. , while driving the trans slipped out of gear, luckily I was able to pull over and nobody was in back of me, when I got it to the dealer, they said the timing chain and guides needed replacement plus the radiator leaked and the trans cooler contaminated the transmission and they both had to be replaced and it cost me near $5000. 00 for total repairs.

2005 Nissan Frontier. Consumer writes in regards to coolant leaks from radiator into transmission.

Bought the truck used at a Nissan dealership. Had under 50k miles. 2 months ago check engine light came on and heat was not working. Had it looked at several times spending money each time but they could not find problem. Last month truck started running rough. Found out this week it needs a new transmission/radiator due to a problem that Nissan has known about for years. There was a class action lawsuit about the problem. They said my truck is too old to qualify for help. According to sites I see we do qualify and I need some help. It overheated today and broke down on highway and is not drivable. I need someone to help me with this.

I was informed that there was a cracked radiator in my truck that was leaking fluids into my transmission. This was on Sunday 9/27/15. The employee of my local dealership informed me about this. The following I was informed by the service department that I would need to replace the radiator and transmission. I was told that this was an "ongoing" issue going on with vehicles that match my make and model.

Tl- the contact owns a 2006 Nissan Frontier. The contact stated that after taking the vehicle on a trip, it was witnessed that the vehicle was leaking transmission and radiator fluid. The vehicle was taken to the dealer where it was diagnosed that water was mixing with transmission fluid, which resulted in the engine failure. Details of the repair was unavailable. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 142,000. Wh.

I bought my 06 Nissan Frontier with 95000 miles great truck loved it when it got to 118000 miles the radiator messed up causing me to replace the rad and trans flush 500$ two weeks later no reverse one day headed home from work going up lick hill second gear gos out causing me to get rearened then there's 200$ for towing and a smashed up truck just spent 8000 on the truck and can not afford to put 4000 more in it what the hell this is a joke my truck will rot to the ground before I spend 4000 more I hope this is taken care of nobody should have to deal with this now I a piece of just that's not worth 2500 Nissan u suck.

Tl- the contact owns a 2007 Nissan Frontier. The contact stated that while driving at various speeds the vehicle would hesitate to shift gears. After examining the vehicle the contact discovered that transmission fluid was present in the radiator coolant. The cause of the failure was not diagnosed or repaired. The manufacturer was not notified. The VIN was not available. The failure mileage was 80,000. Jft.

The contact owns a 2005 Nissan Frontier. While parked, the vehicle failed to start. The vehicle was towed to a dealer, who diagnosed that there was contamination by the engine coolant. As a result, the transmission and radiator needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 104,000.

The contact owns a 2005 Nissan Frontier. While driving at approximately 35 mph, the radiator overheated and allowed coolant to spill into the transmission. There were no warning indicators illuminated. The vehicle began to decelerate and was towed to a local dealer. The dealer diagnosed that the transmission and the radiator needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 85,000.

The radiator fluid leaked into the transmission and ruined the transmission. I understand that this is a known problem by Nissan and they never notified us. If we had been told about the problem before the radiator leak we would have fixed it and would never have had to replace the transmission. We contacted Nissan consumer affairs and they refused to help pay for this so we were stuck with paying over $5000 for a new transmission.

Nissan Frontier has been jerking sporadically for a month driving locally at different speeds city or highway. I assumed it was cheap fuel and a needed tune up. I decided to take the truck in for a diagnostic test at firestone and they were unable to determine the cause or issue of the jerking. Requested diagrams of the engine was unreadable and no help. Firestone recommended I take it to the Nissan dealer. I took the truck to the Nissan dealer and they quoted a $5000 plus repair bill. This seem out of the ordinary for simple jerking and no other symptoms. In addition they had noted on the diagnostic and repair bill some other repairs that obvious needed fixing as good condition. Immediately I knew that the diagnostic test performed was false- the mechanic did not diagnose/test my vehicle correctly and the repair quoted was due to an issue they new about from the start. That's when I started doing online research to see if there were any recalls are problems going on with the Nissan Frontier. My guess was correct. Nissan is aware of this fault regarding the transmission and subsequent issue of the radiator. Nissan dealers are then charging customers to fix an issue that will re-appear. Customers should have some recourse other than spend thousands of dollars on product defect and that recourse should be a recall of these defective vehicles to be repaired. Where is the fairness and why does someone have to die or be seriously injured to prove this is a known defect in the product, Nissan knows its a defect.

My 2005 Nissan Frontier has cross contamination between the radiator and the transmission. Nissan new about this problem years ago. To fix the problem they extended the warranty out to 10 years. Now I need a new radiator and transmission. My cost 3000 dollars. I only had a month left before I was [xxx] out of luck. I have been driving for 35 years and have never had to replace a transmission that only had 67000 miles on it. Poor design and the consumer pays. They wanted to know if I was going to fix it. I told them I had 2 choices fix it or set it on fire. They gave me a strange look. I told them to repair it and I would but Toyota next time. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

With no warning the truck would not start, and just stopped working. We hooked it up to the code reader and did some research online. What we found was really troubling. We bit the bullet and paid to have it towed to the dealer. The dealer looked it over and said that the radiator contaminated the transmission causing a failure in both. They would have to replace the transmission, all the seals and hoses, the radiator and the computer. These repairs were quoted to be $8,000. We just bought the truck which is worth $11,000 and now we are hit with an $8,000 repair bill? this is a major manufacturer failure and was already part of a class action settlement, but since you had to be a part of the class action suit before we even owned the truck we are just out of luck? Nissan needs to buy this truck at full value from us, instead they are trying to take us for another $8,000.
