I bought a 2006 Nissan truck from gary mathew Nissan last year, I was told it was check out and in good running shape I am a 65 year old recent window no one said nothing about a defective transmission cooler that could cause the transmission to fail or that it was factory caused problem that could occur. Last week I was driving it keep showing 4X4 and service engine soon in dash it would lose power to point it would not move until it sit a few minutes.I carried it next day the said it was a lose cable, went home it did same thing several times and lost power on road in traffic, to point it didn't want to move I went to dealer right then. Well they came out with a cost paper to fix it $ $5300 I just sit there couldn't figure how a truck I just got could of tore up I take care of my stuff, including my cars check fluids all I can do, well then a car sales man said maybe better to trade, after hours of this and me not able to trade couldn't afford the 5300 much less in dept 18,000 for another used truck with 90,000 miles on it, I told them to fix it, I'd try borrow money, I was also told may get help from Nissan but looked at their extended warranty only up to 80,000 miles on the transmission thing. We have had Nissan or Datsun too that had over 200,000 miles on them and did fine right up to being replaced, that's why I got my truck, Nissan knew about this problem and knew it would happen, so I am hoping Nissan will help me pay for fixing their mess up. I like Nissan thru years my husband and I had lots of them now I am alone and look what someone else's mistake is costing me I have to middle of week to come up with this money for someone else's mistake.. step up Nissan fix your mistake.

When I got out of college the first thing I wanted to do was to buy my dream car. I had been looking into getting a truck and I was debating between my number one choice a Nissan Frontier or 2nd choice Toyota Tacoma. I knew the Tacoma was probably more reliable in terms of minor parts yet I just loved the design of the Frontier and therefore I bought one in 2006 brand new. Ever since it has been my preferred and only way of transportation. I knew that maintaining it was imperative therefore when it came to an oil change, change of suspension trusts, transmission service, change of spark plugs; it was all done at the proper time. Yet my truck started giving me issues 4 months ago when it would shake or shimmer on road and freeway. Did several tire rotations, did suspension change, yet the issue still persisted. It all came down to a screeching halt when I was going up to sequoia national park for a hike with friends. My Frontier all of a sudden started loosing power and then the gears would just not change. Eventually my 'engine service soon' appeared and was forced to stop our trip. Had to hire a tow truck to bring down the truck and upon scanning I got a P1759 code. Upon researching I come to find out this is a common issue with not only this line of truck but also xterra and titan brands. You cannot believe my disappointment. If it were something simple I wouldn't mind but transmission"!? really?!? because of somebodies' mistake when it came to the engineering of the truck?!" and to find out Nissan is just ignoring the issue. Total disappointment and frustration! now I have to wait for our sweet government to take action since this is a perfect example of a major corporation irresponsibility and ultimately.... greed. Be warned all Frontier drivers, your time will come.

Radiator cracked and leaked coolant into my transmission, killing the transmission.

I actually had a problem with my 2006 Nissan Frontier stalling when driving down the road and found out it was because of ECM relay so I called Nissan dealer and found out there was a recall on the relay. Made a appointment to get it fixed and had them see why I had a hesitation when taking off. Long story short I show back up to get my truck and service advisor tells me I need a new transmission and radiator because of coolant and transmission fluid being mixed.the service adviser was very short with me and sure didn't want to explain anything about the problem, he just wanted me to order $5302.87 worth parts to fix it.I don't know about the rest of you but I don't have that kind of money sitting around to buy a new transmission and radiator.this should be something that Nissan recalls apparently it's a big problem.

The contact owns a 2006 Nissan Frontier. While idling or coming to stop, the vehicle would shutter. The vehicle was taken to the dealer for a routine oil change and diagnostic testing. The technician determined that there was a leak in the radiator causing the coolant to seep in to the transmission. The vehicle was not repaired. The failure mileage was 92,000.

- San Antonio, TX, USA

While driving, the truck stalled on a hill due to transmission failure. Truck began rolling backwards into traffic. Transmission failure was caused by radiator coolant leaking into transmission. This is a known issue by Nissan, and a safety concern.

- Chimacum, WA, USA

I was driving along at highway speeds when suddenly my transmission completely failed with no warning. Thankfully it completely disengaged and did not damage any other systems. When taking it to the dealer for repairs, I was told that there was a crack in the coolant system and transmission fluid and coolant mixed together, thus ruining the transmission. After some research, I learned that this was a known issue and that Nissan did very little in the way of recalls/informing their customers of this potentially dangerous issue.

I was driving on the interstate, and then all the sudden the rpms went up and I had no control with the gas pedal, like it was in neutral, I pulled over to the shoulder put it in park, put it back in drive and it started to go again, as soon as I hit 4th gear it did it again. Took it to the transmission shop and the told me it was the radiator leaking into the transmission because of a cracked line. See this has been happening frequently with this model, why no warning or recall?

- Highlands , TX, USA

Took vehicle to local Nissan dealership for noise that appeared to be coming from transmission with a slight rowing sound when transmission shifted between 40 mph and 45 mph. Shop manager informed me truck needed a new timing chain and fuel tank sending unit. After making repairs to the timing chain which the shop manager specifically indicated that the problem was with the timing chain, my truck still has the same exact problem. These repairs were made at my expense. Now the dealership want me to pay for additional repairs that may not be the problem when they specifically assured me that the timing chain was the problem. I feel that the real problem with my vehicle is the radiator and transmission, which is a nation-wide problem with Nissan Frontier truck transmission and other Nissan vehicles. Nissan is responsible for a re-call on these vehicle. (will seek Nissan Corp. & BBB assist to resolve this issue).

Recently purchased a used 2006 Nissan Frontier from a dealer and after a couple days of driving the check engine light came on, shifted real hard and about caused an accident. After further investigation, we found that there was coolant in the transmission and vis versa. Estimated cost of repair is 5-7 thousand dollars.

Transmission blew due to radiator fluid leaking into transmission. Known problem by Nissan, yet no recall issued and deadline to be part of class action lawsuit has passed.

- San Francisco, CA, USA

While in drive, vehicle does not want to shift into higher gear and took excessively long to gain speed. When this vehicle did eventually shift gears, it shifted extremely hard as if something was damaged. After diagnosed by mechanic, I was told that the radiator had leaked water and antifreeze into the transmission and both radiator and transmission needed to be replaced. I just purchased this truck two months prior. According to the mechanic, this is a problem Nissan has had and known about for several years and has not fixed or made known. I am told this will be an expensive fix, one that I can not afford anytime soon. This is a safety hazard because this vehicle could not speed up and I almost got rear ended several times. Please initiate a formal investigation of this vehicle and the above mentioned problem. This is clearly a manufacturer defect and should be corrected by Nissan.

My vehicle shuddered and felt to slip out of gear while driving! because of this known issue of leaking coolant causes transmission failure. I bought this Frontier with very low miles and was never told of this potential issue from the dealership. It should be a safety recall as it prevents the vehicle from accelerating and if you are driving can cause an accident. I am now reading that Nissan owners have no idea this is happening until too late. Once the coolant is mixed with the transmission fluid this lethal combination kills the valves, seals and torque converter -- rendering your entire transmission useless. I read that this issue is currently contained to the 2005?2010 model years. I have a 2006 with 64K miles! it is only time until this issue causes multiple accidents since this issue happens while cars are driving. Please push Nissan for a recall. I should not have to pay for a known engineering / manufacturing defect.

Transmission was shifting erratic had it towed to a transmission shop. They found that the valve body in the transmission was rusted from a previous radiator failure allowing the transmission fluid and anti-freeze to mix together, see ODI number:10641659. Had to replace the valve body and overhaul the transmission.

Vehicle ran hot, was towed to dealership. Needed a new radiator transmission fluid mixing with antifreeze.

When I was driving on I-4 in orlando fl my transmission suddenly failed from coolant leaking into it, I almost got hit by a tractor trailer when trying to get to the break down lane, come to find out this problem has been known by Nissan for quite some time and they didn't recall, I guess it will take someone getting killed before they are forced to step up and address this know defect, not only is it costly for the fix it's dangerous.

- Debary, FL, USA

The automatic transmission radiator cracked and coolant leaked into the transmission rendering it useless.

- Pflugerville, TX, USA

Issue started as a no start condition. Upon investigation, the truck had a blown fuse and continuously blew fuses. The mechanic determined the fault was with the tpcm contained internally in the transmission caused by the radiator leaking antifreeze into the transmission via the transmission cooler, thus causing transmission failure. Vver upon contacting Nissan customer service, they immediately requested that it be taken to the dealership for determination of failure that I was responsible for the expense. There was no further assistance offered and they stated they would escalate the issue once the dealer diagnosed the problem. Let it be known, Nissan has issued a recall on this vehicle due to the exact problem noted here. My concerns are 1.) why should I encounter a second cost for diagnosis (especially since this is a known issue from Nissan) and 2.) what is my liability and reimbursement once determined the cause of the failure since my mileage exceeds their allocated amount. Prior recalls state that >90,000 miles was $3000 deductible whereas my mechanic could repair the vehicle for approximately $3000. At 117,000 miles, average mileage yearly is less than 15,000 / year. I requested that the regional service adviser contact me (via social network) and telephone but have no contact with Nissan as of this writing. This is clearly a manufacturers defective part which failed prematurely,

Hello fellow "nissaners"! well, was so happy with this truck and my wife as well, because that was her first idea to purchase this good-looking vehicle. Our son was driving our Frontier to school and back home a few years ago, then to a local university. Everybody were so happy! then my son mentioned that truck is behaving very strange: Heavy shaking/jumping at highway speeds around 60-65 mph. I didn't believed it till I draw myself. True! a few times I felt like heavy hit from behind, looks like someone ended up to truck's rear side! then I searched web and after some exploration realized the problem is radiator coolant contaminates with automatic transmission fluid! how"! I opened radiator cup and saw milky substance on it and transmission fluid was not a clear pink color, it was more like pinkish milk shake color! that was it!!! after almost $32K were paid in full and happy family for a few years, now a huge frustration and helplessness!!! dealers "offer a help" only if we pay full price for transmission and radiator to change - about $6K. I have not so much money!!! I heard Nissan refusing a recall on this huge issue. Mr. Nissan or whoever you are, please do something about it, are you sleeping well every night"! we don't!!! are you (Mr. Nissan) afraid to go bankrupt of this big problem - I've bet you are! but think of those people who are behind the wheels of your trucks and SUVS and on this cars one day might get stuck in middle of fast highway because of this failure...!!! I really hope somebody can hear us out there. Please do something!!! please!!! other Frontiers, pathfinders, xterras - please write your complaints!!! don't seat and wait when something will happen, or till something happens!!! thank you!!!

Driving on busy road at approximately 40mph when my truck started to shake, I slowed my truck to approximately 37 mph, when it sounded like my truck exploded. I could not stop and could barely turn the steering wheel enough to get out of traffic just to smash into the curb where I finally came to a stop. The drive shaft came apart, grabbing the emergency brake cable, winding it around one part of the drive shaft, leaving me stranded with minors on the side of the road waiting for a wrecker to tow my truck. Had I have been on the interstate, doing the speed limit (70mph) when this happened, my children and I would have flipped nose over tail, possibly be struck by traffic and seriously injured or killed.
