CarComplaints.com Notes: Radiators are still cracking, leaking coolant and destroying transmissions. Which is a shame when you consider that otherwise, this would be a great small pickup truck.

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.

The contact owns a 2006 Nissan Frontier. While driving 40 mph, the vehicle shifted out of gear independently. The vehicle decelerated 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 radiator coolant tank leaked fluid onto the transmission. The radiator and transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 154,000.

My vehicles contain a defective radiator cooler tank that ruptures and forces coolant into the transmission through the cooler lines. When the coolant mixes with transmission fluid it creates a frothy liquid that eats valves, errodes seals and causes corrosion. It's toxic, irreversible and killed my 5-speed automatic transmission on my Nissan Frontier 2006. Now I have to pay $3,700 for the repair of the transmission. Why Nissan did not repair all the cars? they knew that most of the car will brake pass 100,000 miles. Like mine. Also when you buy a car from the dealer, they do not tel you this problem.

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 for total repairs.

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.

Recently my 2006 Nissan Frontier transmission started to make a grinding noise at speeds when shifting to a lower gear. I checked the computer about possible problems; that is when I found out about the transmission lines failing inside of the radiator. The water was leaking into my transmission. Nissan and the dealership that I was getting my truck serviced knew of the problem for many years. When I asked the service adviser about the problem, he told me my Frontier had 7,000 over 100,000 miles and that was the cutoff for Nissan to help. What made me mad was that I had my 90,000 mile service done at the dealership on 01/28/2014, paid $523.38 and nothing was told to me so I could take action to save my transmission!!! I should had been told of the defective transmission lines before it ruined my trans. Now I am out $3,228.78 for a rebuilt transmission. They knew I had the Frontier, why didn't they tell me of the defective transmission lines... I don't understand...

In February 2015 I started having transmission shutter/shake at 35 to 40 mph. Transmission continued to get worse with the transmission banging into gear at approx 65 mph. Took vehicle to my mechanic who informed me of the ongoing cracked radiator leaking water into transmission problem. Within 4 weeks of first problem, transmission failed completely and I was forced to have it replaced at a cost of $4535.47.

Car would not start, towed to mechanic. He reported transmission needs to be replaced due to contamination. To my family this is a safety issue due to the fact that we live in a very rural area that sees little traffic nor does it have good cell phone reception.

Transmission failure due to a defective radiator. Warning signs of failure. Truck stalls out while driving at normal speeds. The day it went out I was crossing a bridge and came hair of getting rear ended. By the time I got close to home it was just slipping so bad I had to park it. Nissan will not take any responsibility for this and thousands of people are stuck with a $5000 repair bill which the average person like me can't afford. This problem should be a full blown recall on all affected vehicles.

I went to kerry Nissan where I bought the truck when I got the notice about the cross contamination of the transmission fluid and antifreeze due to a defect in the radiator. My truck had 88,000 miles on it at that time. I was told by the dealer not to worry because it was rare for this problem to happen.I asked about preventive measures and was told there was none. I asked about replacing the radiator. I was told that wouldn't help because it would be the same radiator. Now at 108,000 miles my transmission is shot because it's full of antifreeze. The truck has been garage kept, maintained, and looks like new. The dealer has quoted $5,236 to repair. I contacted Nissan they told me I had to take it to the dealer who is charging me $95 to tell me what I already know. Nissan knowing at that time they weren't going to do anything to help me. How do they settle a class action suit for 80,000 miles when all the incidents happen closer to 100,000? there should have been a total recall on all the vehicles affected to replace the radiator with a redesigned one. This is so wrong. I was planning on driving this truck another 5 years.

  • 130,000 miles
The transmission on my truck suddenly went out with no warning during my morning commute in heavy traffic on the 202 loop in phoenix. Shifting to a different gear had the same effect as stepping on the gas, which was that the engine revved with no increase or decrease in speed. I had to coast across 4 lanes of fast moving traffic. It was an incredibly dangerous situation. I am told by the Nissan dealership that transmission fluid mixed with coolant and that it was a catastrophic failure. I have received no notices of any kind from Nissan and was shocked to learn that this is a known, commonly occurring defect and that the defect manifests instantaneously and without warning most of the time. Nissan should be held accountable for the defective system and for not notifying me that I should have the dealer fix it before they put my life and property and that of every person around me at risk.
