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.

Nissan Frontier; truck pick up an vibration that turn into alot of jerking.T alk to the dealer about it, they said to check trans fluid to see if it had a strawberry color to it. If so the radiators was probably cracked and that coolant seep into the trans causing server trans failure. Have no in trans is damage. Now valve body got to be replace with computer board along with all new clutches and radiator going to cost around 5 grand to fix.

Nissan radiator/transmission cooler needs to be replaced at a cost of $3,000 for vehicles up to 100,000 after a class action suit was done. Nissan is acknowledging the problem and I feel this should be cause of a recall and that Nissan should pay the full cost to replace. This cost represent 1/2 of the kelly blue book value on the vehicle. The vehicle is non-operable. The cost also represents about 15% of what the vehicle was originally purchased for. After speaking with Nissan consumers affairs, they say there is nothing else to but to contact you to try to change it to a full recall.

As I am driving, the transmission will not shift at 40 mph. I pull over and find out that it will not go into reverse, either. I drive over to the Nissan dealership and find out that the part of the radiator that connects to the tranny has cracked and dumped all of the radiator fluid into the tranny, killing it. I need a new radiator and transmission. Nissan is covering the costs (for repairs but not alternate transportation for the week that it is taking to fix this) but upon returning home and looking online, I found out that Nissan has known about this problem for about 5 years and instead of doing a recall (costing lots of money), they extended the warranty on the radiator assembly from 3 years/36,000 miles to 8 years/96,000 miles hoping that problems will occur after that time and then they are off the hook for repairs. How dangerous could this have been under different circumstances. I am angry and disgusted with the way Nissan has handled a problem they know could have caused a serious safety risk.

This issue is my radiator and transmission contamination. First noticed heat didn't work. Mechanic checked radiator, found leak. Began installing new radiator and saw that coolant was already contaminating tranny. Truck dead at dealership. Called Nissan and they created a case. Denied. Escalated case. Denied. Started new escalation today. I have lost my job because I cant get there!!! what's next my home"??? paid outright for this truck brand new. Drove all the way to Maryland to get it. Less than 5 yrs old!!! but because my mileage was over the 80,000 they wont help. This product already had the flawed components when I drove it off the lot brand new so wtf should mileage have to do with it??" all the faulty sensors were annoying enough but this type of potential for failure should demand total recall....instead they issue warranty extensions and mileage limitations. I was never notified as a registered Nissan owner when this issue was supposedly sent out last fall. And even if I had been my mileage was already over. That should not have mattered as this issue is such a safety and monetary concern. Luckily it didn't fail while I was driving home at 8pm doing 70mph or when I had my kids in it. All in one week I lost vehicle because of flawed product, my job because my flawed vehicle died and my reputation as a reliable and responsible employee. Heartbroken. I want my money back!!!!!!!!!!! never will I buy another Nissan. Greedy & irresponsible company with no sense of commitment to their consumers.

Known issues with faulty radiators is causing it to fail and mix antifreeze into the transmission causing the transmission to fail.. the result is a ~$9200 bill from your dealership for a new transmission and radiator.. Nissan absolutely refused to take ownership of this issue making me the owner of my 4th Nissan truck to pay..

On July 2011 had to pay for new transmission for my truck after the radiator leaked in to the transmission, talked with Nissan and tried to get them to stand behind it and they said they would have if the truck was, in side the new warranty they had put out but I was at 91611. They know what is wrong and how to fix this. They have to put the transmission cooler on the out side of the radiator about $ $200 fix.this replace cost, me more than $ $6000 to get fixed. Now at 97980 miles we are back at the shop having the same thing, done over again, this time they are covering after I had to have a out side tech come in and prove that this was happening again. The first said it had to be replaced and then they had another one check it and said I was hearing the tires and the transmission was good. I would not pick up my truck because the 12 month warranty was about to run out on July 26 2012. After the out side tec checked it out and said the transmission had coolant mixed with it they ordered every thing new again...should not have had to pay for the first one..

I am the original owner of a 2007 Nissan Frontier with 114,000 miles. I took my car into the local Nissan dealership for service due to transmission issues. Their assessment astounded me. They informed me that the transmission and radiator needed to be replaced due to a known manufacture defect in the radiator causing antifreeze to be spilled into the transmission. The quoted repair was over $6000. This is my only vehicle and I'm still making loan payments on it. I've treated this vehicle with kid gloves and followed the maintenance schedule religiously. This mechanical issue is due to something that was originally sold to me defective and Nissan of North America is unwilling to cover the repairs. This is a widespread issue and has affected many Nissan owners. There are even class action lawsuits against Nissan to get reparations for repair bills already paid.

The contact owns a 2007 Nissan Frontier. The contact stated while driving at 25 mph, the vehicle lost all power and he had to utilize the emergency brake in order to stop the vehicle. The vehicle was towed to his residence and the dealer was contacted. The dealer advised there were no recalls on the vehicle and any repairs would be at the owners expense. The manufacturer was not contacted. The failure and current mileages were 81,000.
