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.

Recently my 2006 Nissan Frontier transmission started to make a grinding noise at speeds when shifting to a lower gear. I checked the computer about possible problems; that is when I found out about the transmission lines failing inside of the radiator. The water was leaking into my transmission. Nissan and the dealership that I was getting my truck serviced knew of the problem for many years. When I asked the service adviser about the problem, he told me my Frontier had 7,000 over 100,000 miles and that was the cutoff for Nissan to help. What made me mad was that I had my 90,000 mile service done at the dealership on 01/28/2014, paid $523.38 and nothing was told to me so I could take action to save my transmission!!! I should had been told of the defective transmission lines before it ruined my trans. Now I am out $3,228.78 for a rebuilt transmission. They knew I had the Frontier, why didn't they tell me of the defective transmission lines... I don't understand...

Vehicle's coolant is leaking into transmission, causing erratic shifting while driving. I'm told the transmission will eventually fail while driving.

The transmission is failing at only 75,000 miles. I had the radiator replaced after a brief overheating issue. There was a brown like puddy that began to develop in the vehicle's system at that point and a sluggish transmission, stalling and failing requiring constant restarting and constant sitting and repair costs for the vehicle.

I purchased a 2006 Nissan Frontier 4X4 truck on 7/28/15 and have since discovered it had serious transmission problems. I took it into Nissan of Tacoma to be looked at and was told that this is a problem that Nissan knows about so they will pay all but $3000 of the repairs. I was told this was an inherent problem with this model and others made by Nissan and Nissan has since changed how they built their cars. I have been told I can only drive it semi safely around town, no going over the mountains and absolutely no towing with it which is why I bought this truck, to tow my trailer. I am a disabled senior on a fixed income and have no extra money to fix much less buy a new vehicle. I owe around $27000. On it and went as far as to buy an extended warranty which will not cover these issues. I do not understand why if this is that big of a problem it has not been recalled. This vehicle has 7 other recalls per you website so this becomes a real problem.

Radiator developed leak and leaked antifreeze into transmission. Destroyed transmission. Had to have total rebuild on transmission and new radiator installed. Transmission fluid was bleeding back into radiator. Contacted 2 different Nissan dealers when it first started. They assured me Nissan was not having any radiator problems. Told me to check U-joints and drive line. Said it would be very hard to find problem since service engine light was not coming on. A friend recommended a mechanic and he knew exactly what was wrong. Big bucks to fix.

I bought a 2006 nissian truck from gary mathew nissian last year, I was told it was check out and in good running shape I am a 65 year old recent widow no oe said nothing about a defective transmission cooler that could cause the transmission to fail or that it was factory caused problem that could occure. Last week I was driving it it kepf showing 4X4 and service engine soon in dash it would lose power to point it would not move until it sit a few minutesw.I carried it 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, includinf 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 nissian but looked at their extended warrenty only up to 80,000 miles on the transmission thing. We have had nissian or Datsun too that had over 200,000 miles on them and did fine right up to being replaced, thats why I got my truck, nissian knew about this problem and knew it would happen, so I am hoping nissian will help me pay for fixing their mess up. I like nissians thru years my husband and I had lots of them now I am alone and look what someone elses mistake is costing me I have to middle of week to come up with this money for someone elses mistake.. step up nissian fix your mistake.

The radiator coolant drained into the transmission cousing the transmission to break down. According to my mechanic this was due to a diffect on the manufacture of the radiator, my truck, in this case is a 2006 Nissan Frontier. The total amount I had to pay for the repairs was $3963.08. Nissan should be accountable and responsible for this issue in this trucks.

Vehicle began to shift upward and downward erratically at various speeds and RPM. It would also shake and shudder like the whole vehicle was on a rocky road -- everything vibrating from the frame to the steering wheel. Very sudden, alarming, and disconcerting.

Coolant fron radiator entered transmission causing shuttering. Vehicle was brought to Nissan for repair. Engine coolant had entered the transmission causing failure to transmission. Coolant system was replaced and transmission was flushed. After 5000 miles the transmission had completely failed. The failure occured while attempting to accelerate from a stop sign in a dangerous intersection. The vehicle was stuck in 4'th gear. I accelerated from the stop sign but the vehicle would barely move leaving me exposed in a dangerous situation. A vehicle almost T-boned me as it came around the blind corner. Nissan has known about this defect for a long time. If I had known I could have replaced the coolant system before it entered the transmission. Now I am stuck with a bill of more than $5000 after already spending $2000 on a new coolant system and numerous transmission flushes. In my opinion Nissan neglect in notifying and remedying this defect is placing its custumers at great risk of injury and death due to this sudden loss of power.

2006 Nissan Frontier - steering wheel has become very loose, and physically moves, while operating vehicle. The steering has also become very tight and difficult to steer vehicle. A deadly combination!!!!!!!!!! came to a traffic signal, after traveling on the interstate for approximately 300 miles. While stopped I noticed alot of play in the steering wheel and steering became very tight at slow speeds. The movement in the steering wheel was very pronounced moving right and left up to two inches in either direction. I showed my wife and kids, who were in the vehicle, and I became very concerned for our safety, as we still had nearly 100 more miles to drive to reach our destination. No dealership was in our vicinity, so I drove vehicle back home two days later. On the return trip I was very aware and nervous for the safety of myself and family, I have never had a steering wheel move like that (and it shouldn't). Was concerned and very nervous the steering could either fail or the airbag could inadvertently deploy causing risk of injury or death to my family or other motorist. I called my local Nissan dealership (carriage Nissan, gainesville Georgia) on 6-18-2012 to discuss my observations and they informed me they had not heard of any issues or problems with steering. Unfortunately for Nissan, after I investigated my issue on the internet, "I am now convinced that Nissan is well aware of these problems with steering issues, as they have been reported numerous times to Nissan usa corporate headquarters". according to the internet, by Frontier truck owners, Nissan dealers are replacing steering columns to fix this design and construction problem. It is of concern to me that the NHTSA has not forced Nissan to correct this potentially life threatening issue, by forcing a recall, since it appears Nissan has no intentions of voluntarily fixing their problem.
