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

  • 77,558 miles


I purchased my vehicle directly from the manufactured on June 27, 2006. On or about September 26, 2014 my 2006 Nissan Frontier started having a strong vibration causing my steering the be unstable and the automatic transmission seemed to slip and then catch when my car changes gears from 30-35-40-45-50-55 mph. On October 3, 2014, I took my vehicle into the Nissan dealership here on kauai and after 5.5 hours I was informed my radiator had a crack and was leaking into my transmission. I was told there was a class action lawsuit file regarding this issue and there was now extended warranties on these parts for failure. The extended warranty for no cost to customer is 80000 miles/8 years. My vehicle is under the 80000 miles, but I am over the 8 years by 3 months. I spoke with the manager and he called Nissan North America to see if there was anything they would do regarding the fact my truck was only 3 months over the 8 years and below the miles on the extended warranty. I received a call back from him stating they would not cover anything additional and I would need to cover the $2500 co-payment to replace the radiator and transmission. I was however told if I wanted to trade in my vehicle for a new one, they would deduct the $2500 from the price of a new vehicle. I told him I would not buy another Nissan sine they do not stand by their product. There are hundreds if not thousands of people who bought Nissan with this issue. Nissan is aware of the problem and there should be a recall on this item as it could cause the transmission to cease. I now have to drive this vehicle with the vibration I believe is unsafe until the parts come in. I guess they are going to wait until this causes an accident and someone gets hurt to recall the defect in their automobiles.

Follow up to complaint 10584635 -- timing chain failure resulting in catastrophic engine failure. Known issue by Nissan, but hidden from consumer. Nissan has issued several service bulletins related to defective timing chains, and noted that these can result in catastrophic engine failures, exactly as occurred. Dangerous. No warning and complete failure on a busy roadway, with loss of the ability to maneuver and extremely hindered ability to get to safety in time. Had I been going faster than 35mph, or had I been on a freeway, this could have been deadly. I discovered a class action lawsuit regarding this issue, and it appears this is affecting thousands of people. Nissan sold vehicles after it knew about the timing chain defects (the bulletins went out in 2005, and this vehicle was a 2006). Nissan deceptively kept this from consumers. Timing chain defects occur typically after warranty expiration, and they do not make you aware of the potential prior. Consumer unfairly burdened with full loss of engine and nearly the entire value of their vehicle.

While returning home, the vehicle lost all power and power steering. Difficulty navigating to safety on the side of a busy roadway. The engine in the vehicle had completely seized. Complaints to Nissan that something was wrong with this vehicle had been ongoing. The entire fuel system had failed at 40K miles. Both catalytic converters failed at 55K miles (thought to be related to an engine problem, but they would not fix it even under warranty). At 63K miles, the engine started to show signs of problems. Repeated analysis, for which I paid, resulted in no conclusion. Only that "something was wrong". tried to engage Nissan multiple times to fix this. They refused. Now, the engine has failed entirely. Nissan will not acknowledge defective manufacturing. The vehicle was purchased brand new and has been meticulously maintained. The engine failure and the resulting loss of the ability to maneuver or operate the vehicle was, thankfully, on a road that had a low speed limit. Subsequent research related to this issue shows that there is a class action against Nissan for premature engine failures in these vehicles, and that they allegedly hid known issues and were deceptive to consumers.

We bought this Nissan new in 2006 -great little truck. But recently the engine would stall and all the lights on the dash came on. Took it to our mechanic he said it was a tran code took it to the Nissan dealership and they said the coolant had gotten into the trans or vise versa (a lot to take in),so I needed a new transmission and radiator. I found this issue on your website for a recall but my vehicle was within the years of the recall but it has over 100,000 it has130 so the dealership said there was nothing they could do to help with the $5500 bill they just quoted me. Is there any help out there for me on this issue"?" please.

At low speeds the transmission stutters / hesitates. I've been told by Nissan that I need a new valve body. I believe my vehicle suffers from the radiator / transmission issues as experienced by many other customers.

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.

Frontier 4WD 6-cyl

  • 99,000 miles
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 attempting to shift into reverse, the vehicle failed to respond without warning. 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 and the power transmission needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure and current mileage was 106,000. The VIN was not available.

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.

Frontier 6-cyl

  • 82,893 miles
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.

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.

Frontier 6-cyl

  • 99,800 miles
When driving, a "rumbling" noise would come and go and a "whining" noise while accelerating. The rumbling noise was not consistent but would sound like a was driving on the side of the round. It would usually appear around 40-60 mph when I would let off the gas and "coast" and try to press the gas again. I did not know there was a "warranty extension". I was not notified. Took the truck into the shop only to find out my transmission was going out due to the fact I have radiator coolant (antifreeze) in my transmission fluid; (over a gallon) cause by a factory defect. Something to do with a transmission piece going through the radiator and leaking. Mileage for my truck is right at 99,800. Barely made the 100,000 miles 3000 dollar so-called Nissan warranty extension..
