Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: For years, Nissan trucks and SUVs have had problems with coolant destroying the transmission. And for years, Nissan has done nothing about it.

The 2007 is no different than the 2006 and 2005. Just avoid it.

Truck would not start. Towed to auto garage. Told radiator has a defective coolest line that runs thru transmission. This caused cross contamination of radiator fluid and transmission fluid, causing breakdown of transmission and radiator. Found out online that this happens with three types of Nissan vehicles made between 2005 and 2010. Nissan will only cover if under 100,000 miles but I have to pay first 3000 on a fix averaging 3800 to 4000. I was never notified of any problems by Nissan. They knew their was a problem and I believe that are stalling and covering this problem. They should be 100% responsible for this liability. Car company's paid for all types of recall for their design flaws, what is the difference here other than the amount needed to do what is right.

I first began noticing a problem with my 2007 Nissan Frontier when the heater was having trouble heating up the cab as I was driving. At first the problem was intermittent and the heater would warm up for a while and then get cold again. Shortly after that I began to notice a vibration or shuddering at higher speeds as if I was hitting a rumble strip. I began doing some research on the internet and found that this is a very common problem with several Nissan models between 2005 and 2010. I took the truck to the local dealership and they knew immediately what the problem was and what was needed to repair it. The radiator develops a crack that leaks into the transmission and starts tearing up the internals of the transmission. The dealership recommended replacement of both the radiator and the transmission. The cost to do this repair was about $5,100. The cost was not covered in the Nissan extended warranty because the truck had over 100,000 miles. I am extremely frustrated that Nissan does not stand behind their vehicles. I did not receive any notice from Nissan that there was an engineering defect in their cars.

I took my vehicle in for service 12-17-14, since the heater was not working properly and just found out the that radiator cracked and leaked radiator fluid into the transmission, possibly contaminating the transmission. They are replacing the radiator and flushing the transmission a few times to try to salvage the transmission. They informed me of a recall on this problem but I'm past the permitted mileage. I bought the vehicle used in 2012. The service dealer said the recall included a new radiator and transmission for $3800 but that the deductible was $3000"?" this is a serious design flaw that should be fully covered and fixed by Nissan!

The D for drive would no longer show -to took it transmission place and they detected coolant leak into transmission. Found out Nissan had lost a class action suit over this and realized my truck is over limit for milage this is second major repair for this vehicle had a transmission control module replaced and was partially reimbursed after a big fight with dealer and Nissan. Will never buy another Nissan after this I hope you hang them out to dry over this.

Purchased the vehicle on 8/16/2014 and I was driving the vehicle to work and transmission wouldn't shift out of gear along with the check engine light came on. I scanned the vehicle and pulled a code for the transmission output sensor. Took the vehicle to the dealership where they said they found coolant in my transmission and I was outside of the previous extended warranty and they've never seen this before. They told me I needed a whole new transmission and radiator. And Nissan wouldn't cover any of the damages due to it being out of the last extended warranty that was added to the vehicle. Now they want to charge me $6,756 to repair my vehicle I've owed for less than a week.

Transmission failed due to radiator leakage into transmission fluid. Just out of warranty! Nissan claims powertrain warranty will not cover since it is a radiator problem which causes the failure. ----- leaking coolant causes transmission failure an alarming number of Nissan xterra, pathfinder and Frontier owners are stepping forward with stories about how cracked radiators are causing coolant to leak into the transmission. Once mixed with the transmission fluid this lethal combination kills the valves, seals and torque converter -- rendering your entire transmission useless. This issue is currently contained to the 2005żż2010 model years. Some articles online claim that being aware of the proper warning signs may help prevent your Nissan from needing a rebuilt transmission. These warning signs are: Heavy vibration while shifting heavy vibration while accelerating abrupt stalling shuddering noises car doesn't warm up when sitting owners who have had their radiator crack are claiming that even if you catch it early, your transmission is still doomed trouble due to this engineering / manufacturing defect. You can read their stories over at for the three Nissan models that are showing the defect: Pathfinder: 2007, 2006, 2005 xterra: 2005, 2006, 2007 Frontier: 2005. 2006, 2007 perhaps even more troubling is owners who have already had their transmissions "repaired" by an authorized Nissan dealer are still reporting catastrophic transmission failure. Through no fault of their own, Nissan owners who are out of warranty are left to cover the hefty repair bill, which can be over $4,500 when all is said and done.

Over the course of approx 2 weeks the vehicle experienced transmission slippage and engine overheating. Then the transmission ceased to function. The vehicle had to be towed to a transmission shop. The transmission failed due to radiator coolant leakage into the transmission. The vehicle needed a completely rebuilt automatic transmission, and radiator. Total repair fees were $3495 including towing. Was told by transmission shop that this was a very common problem for Nissan radiators. Called Nissan local dealership, they quoted a price of over $5500 just for the transmission. Radiator and towing would be extra. I was informed that Nissan refused to offer warranty or other compensation.

I was driving down a back road. While traveling up a slight hill the truck slipped out of gear. When I pressed the gas pedal the engine would rev but it would not accelerate. I pulled to the side of the road and turned off the truck. When I restarted and put it in drive I started rolling backwards. I ended up getting towed to my mechanic. If this was the original transmission I could understand that at 155K miles it could fail, however this truck has now gone through the factory transmission as well as a factory refurbished transmission all within 7 years. I read online about many Frontier owners having the same issue as I have. I brought the truck to my mechanic who informed me that the radiator fails which causes the transmission to fail. I feel lucky that I was on a back road because the failure happened quickly, had I been on a highway with moderate traffic I could easily been stranded in the middle of the road.
