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.

Frontier 6-cyl

  • 87,870 miles


Vehicle began to shift upward and downward erratically at various speeds and RPM. It would also shake and shudder like the whole vehicle was on a rocky road -- everything vibrating from the frame to the steering wheel. Very sudden, alarming, and disconcerting.

When set in D, the RPM's dropped. Next day driving 20 sec. And looses all power. Can shift the gear stick, but the transmission does not engage. No audible warning or anything like that. Just stopped driving. Got code P1759 and P1769. Needs new transmission and radiator because the coolant leaked into transmission. $5500 is the quote from the dealer.

I have a 2006 Nissan Frontier that is having complete transmission failure due to the known issue of radiator fluid contaminating the lines to the transmission and causing internal failure. I have been quoted $5,000 in repairs for the radiator and transmission. There is a class action lawsuit against Nissan for this very issue for several models. The dealership acknowledged the lawsuit, however, said a settlement or recall has not been issued at this point and they could not discuss it any further with me. They suggested I trade the car in and buy another from them, even suggesting another Frontier.

I have a 2006 Nissan Frontier and for the last 9 or 10 months it becomes "herky-jerky" at various speeds. I only drive this vehicle in the winter so yesterday I took it in to the dealership and today they informed me the coolant had leaked into the transmission. The dealership informed me the cost for the repair is $6500. I asked them if this was something normal and they said it was unusual. I did some checking on the internet and found out there was a settlement agreement regarding this defect. Other sites directed me to make a complaint with you because this appears to be a widespread problem and due to the fact the settlement agreement was essentially worthless. Given this I am filing this complaint with you in hopes this will turn into a recall. Also, made a claim today with Nissan and expecting a case worker to call back tomorrow. If they do not agree to pay for the cost of the damage I will take them to small claims. Of note, I have only sued one entity before in my life (49yo) and it was Nissan back in 1997 and I won. It was a defect in the wiring of my previous Frontier. I can say Nissan likes to play hard ball and not settle or admit to any of their faults. I gave them more than sufficient evidence and was very patient in this prior claim, but they kept denying. I learned my lesson that time and this time I will not be so patient and will inform them I will taken more expeditiously this time.

The contact owns a 2006 Nissan Frontier. The contact stated that while driving approximately 35 mph, there was a sudden loss of power steering without warning. In addition, the contact stated that the fuel gauge failed to display accurate fuel levels. The vehicle was taken to a dealer where it was advised that the fuel level sending unit inside the fuel tank needed to be replaced. Also, the vehicle was taken to a private mechanic where it was advised that the radiator fluid was leaking into the transmission. As a result, the radiator, the power transmission, and steering shaft needed to be replaced. The manufacturer was notified of the failure and stated that the vehicle was not included in NHTSA campaign number: 10V075000(fuel system, gasoline). The vehicle was not repaired.

  • 101,000 miles
My 2006 Nissan Frontier SE crew cab check engine light came on at about 100,000 miles. I read the code and it indicated that an emission problem (I.e. a sensor or catalytic issue) was the matter. Soon after the truck began to exhibit a strange vibration in what appeared to be the engine specifically around 40-45 mph. I brought the truck in at 101,000 miles to have it serviced at the dealership. They determined that not only did the catalytic converter need replacing but also there was radiator fluid in the transmission and the bill was over $6,000. I declined the service and immediately called Nissan North America. They explained that I was 1000 miles over the extended warranty and wished me to have a nice labor day weekend.

I was driving on the freeway and notice smoke coming from near (it turns out it was coming from underneath) about few seconds later the check engine light is flashing, my Nissan pickup engine lost some speed and it appears to have lost power as well because it was not accelerating. I took it for inspection to 2 different auto shops locally and have gotten the same reports from both shops.I have a bad transmission and radiator coolant leaks seems to have caused the transmission failure. I have taken my pickup to Nissan after learning about the extended warranty to roseville future Nissan and they seems have agreed about this known issue. They said Nissan has extended the warranty up to 100K miles (so technical it should be covered), however they are asking for 3000K for deductible. I have contacted Nissan Consumer Affairs and they said they are waiting for court to decide on this known issue and will not be able to help until it's resolved. I did some research online and found out I was not the only one having this issue. Please help and advise if I need to take action against Nissan as this is clearly a known issue and they should not be asking for 3K.

I got a check engine light on my Nissan Frontier and brought it to the Nissan dealership to have checked and was told I would need to replace the entire transmission and radiator because engine coolant has leaked into the transmission and is destroying the transmission a quick search it seems there are hundreds if not more of people with this same issue of Nissan having a poor design and putting many people at risk by having their transmissions seize up at any given time while driving. Having coolant leak into the transmission is not a normal wear and tear issue and is gross negligence on behalf of Nissan to ignore this problem.

Frontier 6-cyl

  • 143,396 miles


I have a 2006 Nissan Frontier SE 4X4 crew cab with 143396 miles and going about 40-45 miles per hrs I hear a chatter in the rear of the truck. Made an appointment with a Nissan dealer in my area and the out come was.. the truck needs a transmission and radiator replacement and it is out of warranty the replacement at the dealer would be a cost to me of $5132.13. Nissan had a class action suite in New York and the only win for us consumers was that they extended the mileage to 100,000. I called Nissan and was informed that if I had 120,000 miles on the truck that there would be a cover under the warranty. Nissan knows that there is a issue with tranny and radiator but they did no recalls so now we are stuck. If you are on a fixed income who has over $5000 dollars laying a round for this kind of repair. I can still drive the truck but its not safe if the tranny shuts down on the hwy then what ? looks like a accident waiting to happen. Cant have that. So the truck will sit in my yard till I get some answers that will help me get this issue solved.

As I began to enter the highway and increase speed to about 65 mph, I noticed what felt to be a slip in gears. Each time I decreased by speed and increased over 50 mph, I could feel the same type of slip. Although I drive my vehicle daily, it is usually for very short distances, as I am in town driving. I have only noticed this slip of gears while on the interstate. Today I took my vehicle to the Nissan dealership for diagnosis. I was informed that I was no longer under warranty and would have a $2500 deductible for the replacement of the radiator & transmission. My vehicle is properly maintained at recommended intervals, with low mileage. I came home to do some research and learned about the reported radiator/transmission problems for some 2005-2010 Nissan truck and SUV models. I do not remember ever receiving any information from Nissan regarding the potential transmission failure for my make and model and I am disappointed to know that a recall was not issued, as this is a serious safety issue. The service manager also did not mention any of this to me. The only thing that clued me in to an issue was that he mentioned "deductible" and that I was just about 3,000 miles over the warranty. Knowing that a power-train warranty is usually 36/36000, I started thinking, how could I only be 3,000 miles outside of the warranty? Nissan should be held accountable as numerous reports have been made. Extending a warranty to 8/80,000 is also a joke, since most of the reported issues, have not occurred until after 80,000, as in my case. I should not be stuck with this maintenance bill; this is Nissan's responsibility. Sometimes doing the right thing as opposed to doing the most profitable is in order. Too bad Nissan does not care enough to keep their customers satisfied, but most importantly, safe!

I had driven aprox 20 miles on interstate when I noticed when truck shifted between 4th and overdrive the motor was racing. I turned off cruise control and turned of the overdrive with the trailer switch. I stopped at station checked fluids but everything seemed ok. When leaving station the transmission was slipping when shifting. I was able to drive it home. Next day transmission shop told me transmission would need to be rebuilt. After google info I told shop to also replace radiator also. I got the truck back 2 weeks later. After 5 days of driving while traveling home from job. Transmission locked up and truck came to stop in middle of road. I looked under hood and found oil in radiator. The truck was towed back to shop. Come to find out the shop had replaced with used radiator. The same thing had happened again where antifreeze mixed with transmission oil causing extensive damage, still in shop and waiting on its return. Spent 12000 on truck and in first month. 400 miles and 3000 in repairs. And still climbing.

Transmission cooler failed causing coolant to mix with transmission fluid. Transmission subsequently failed. Nissan would not cover the repair even though the problem is a known defect. ~$4000 cost of repair and an independent transmission shop.

Had a bad vibration in the drive line at a low speed. Thought it might be a U-joint. Began a search on line and found an article on the Frontier's anti-freeze mixing with the transmission fluid and coolant entering the transmission causing failure. I checked the overflow tank and it had trans fluid on top of the coolant and the radiator had a red foam coming out. Took it to the Nissan dealer and it was confirmed.

Whilst trying to drive forward, the vehicle is unable to have enough momentum to drive- in other words the transmission is not functioning correctly. According to the mechanic I brought it to, I was advised that he has seen this happen with this make/model/year before and it is caused due to an issue with the radiator leaking anti-freeze into the transmission system.

The transmission stopped and my vehicle would not go faster than 2 mph. I could not get it uphill. I had to have it towed. It was constantly jumping forward prior to this incident. On the highway it felt like it couldn't get out of gear.

I was driving on a major highway when all of a sudden the automatic transmission downshifted into second gear. The Frontier immediately slowed down. I was driving in front of a tractor trailer and just missed getting rear ended. I've since found out that Nissan has been aware of the radiator leaking and cross contaminating with the transmission fluid and blowing out the transmission. This is a dangerous situation with these vehicles involved and Nissan should be responsible for correcting their defect regardless of vehicle mileage. This vehicle needs to be recalled and fixed.
