Radiator problems of the 2006 Nissan Frontier - part 2

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!.

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.

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.

Hello, I have a 2006 Frontier on it's way to the dealership right now having the radiator & transmission replaced. That is caused from the coolant mixing with the transmission. I don't know how Nissan can say this isn't a safety issue when your vehicle can stop in the middle of highway traffic due to your transmission dying. Recall needed! thank you!.

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. .

Transmission failed completely while my daughter was driving leaving her stranded in a busy intersection. Vehicle was towed. Transmission was found to have radiator fluid in it as well as transmission fluid in the cooling system. After investigating this issue on the internet it is obvious that Nissan has been aware of the issue with faulty radiators for a long time. (when I was still under my extended warranty. ) had Nissan informed owners this could have resolved with a radiator change that I would have gladly done at my expense. Now I'm looking at over $4000. 00 in repair costs. Shame on Nissan!.

Hasn't happened yet, but from all the complaints from 2005-2010 Nissan pathfinder, xterra and Frontier owners concerning major transmission failures while driving due to cross contamination from a failed transmission fluid line running through the radiator, it's only a matter of time. This defect has been known by Nissan for years and as a band-aid solution offered extended warranty coverage for these specific components to 8 years/80,000 miles, knowing full well most problems have a record of occurring just after 100,000 miles. Class action law suits against Nissan for this defect are now pending in the state of new york. This defect and Nissan's lack of concern for preventative action placed this in the 2nd worst problem on carcomplaints. Com top vehicle problem trends of 2012 list. As more and more of these model years approach 100,000 miles, more and more catastrophic failures with potential for injury and loss of life will occur. Repair after the failure is quite expensive; enough to warrant scrapping the vehicle for those that can't afford the repair bill. Time to hold Nissan accountable for the problem they have created and allowed the public to bear responsibility for. A recall of all affected models to install an improved automatic transmission line in the oil cooler or rerouting the line to a different add-on oil cooler is needed.

Camshaft sensors (cps?) replaced today at dealer. Friday my truck stalled as I pulled into a highway at night. Almost got broadsided by tractor trailor truck. These sensor failures cause a rapid stall under power and hard starting after the stalls. Last month I had the crankshaft sensors replaced as well. Before that the ipdm relay recall gave me problems. I'm still fighting to get my fuel sending unit replaced (Nissan will only cover customers that spend a lot of money at the dealers, I was told this by Nissan!). I've had the rear end, transmission and radiator, driveshaft and propeller shaft replaced due to failed u-joints. Axle seals (on the new rear) are leaking again I understand a clogged vent may be to blame. Tire pressure sensors are shot and catalytic converters shot. Get this company to recall some of this stuff and force them to pay to fix this junk before someone gets killed!.

On my 2006 Nissan Frontier my radiator coolant mixed in with my transmission oil and it caused my tranny to blow out and also for my timing belt to get messed up and so I had to replace my tranny and radiator and timing belts at a total of over 4 thousand dollars. I really think Nissan should make this a recall regardless of your mileage because if they don't hundreds and thousand of people will stop buying Nissan. Please inform me of anything with the investigation with Nissan.

The transmission has been compromised due to a faulty radiator. The radiator leaked coolant into the transmission contaminating the transmission fluid. I noticed the vehicle would occasionally shudder and when I had it checked out discovered the problem. Hard to believe Nissan did practically nothing to notify owners of the problem because it sure was evident that the local Nissan dealership was aware of the problem as well as a couple of transmission shops I've visited.

Mechanic stated antifreeze is leaking into transmission. Replaced radiator, flushed transmission.

My 5-speed automatic 2006 Nissan Frontier's radiator cooler tank ruptured forcing coolant into the transmission through the transmission cooler lines causing "catastrophic failure" at 92000 miles on the odometer (12000 miles outside the extended warranty on the faulty radiator). This is apparently an "uncommon", but known problem with Nissan truck and SUV models. I was traveling at 65 mph on interstate 70 near frederick, maryland when the transmission failure occurred. I lost all forward momentum but was able to maneuver the truck to the shoulder before causing an accident. I had it checked by an independent shop in mount airy, maryland and they quoted the replacement of the radiator and transmission at $4350. After making inquires with the Nissan dealership where I bought the car new in 2006, their initial estimate was between roughly $6000 - $10000 for replacement of the radiator and transmission! they were able to negotiate down with Nissan corporate and the final cost of replacement of the radiator and transmission was $3000. My transmission failed without any sign or warning at 65 mph on a 3 lane interstate - the financial burden to fix the problem hurts, but it could have gone much worse.

Was parked at store with truck running when it ran hot. With further look it was the transmission oil mixing with the coolant. Replaced radiator. Now transmission is slipping and now not pulling.

I have a Nissan Frontier that has had failed in a number of things which are not wear and tear. They are design flaws. The fuel gauge module. The radiator/transmission leak flaw. Because of the design of the radiator, now a perfectly working tranny needs rebuilt. I also hear the tensioner for the timing chain is a defective design. My Frontier began falling apart before the 100. 000 miles with design flaws. Nissan never again. A simple warning letter that my radiator needed a $300 repair would have saved me $4,000 later and not leave me stranded in traffic.
