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.

problem #117

  • 92,000 miles


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.

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.

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?

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.

  • 107,482 miles
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.

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.

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.

Contacted a mechanic because my truck would shake at speeds at or above 50 mph. It was also starting to shift very hard. The mechanic checked it out and told me that there was a very common problem with the radiator failing and causing coolant and water to get into the transmission... which isnt good at all for it. Radiator and transmission are shot and need to be replaced. He tells me that Nissan has had this problem for some time now which was news to me. You would think Nissan would let owners know about a problem so severe and common. Now I'm on the hook for $4000 thanks to Nissan and it very unprofessionalism.

I am yet another victim of the transmission/radiator problem along with hundreds, possibly thousands of other customers. Defective radiator allowed coolant to mix with transmission which is now outrageously expensive to repair.
