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.

CarComplaints.com 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.

After reading about previous complaints online and an investigation performed by NHTSA I think the transmission is leaking fluid into the radiator. What was the conclusion of your investigation?

Vehicle began running poorly and stuttering between gear shifts. Knew about the potential for the transmission and radiator fluid to mix and destroy the engine from the lawsuit that was filed and correspondence we had received from Nissan. Sure enough, took the vehicle to a Nissan dealer and an independent car shop and both diagnosed the same thing - radiator and transmission fluids mixing. No option but to get it repaired for a whopping $4,409.26. It is disgraceful that Nissan will not formally acknowledge this defect and pay for the repair bill no matter what your mileage. This was our first and last Nissan.

The contact owns a 2007 Nissan Frontier. The contact stated that while driving at various speeds, the vehicle would exhibit a loud whining sound. The vehicle was taken to the dealer and the technician diagnosed that the timing chain was defective and needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was not repaired. The VIN was not available. The failure mileage was 59,188 and the current mileage was 59,350.

Engine whine started before warranty expired but thought it was a power steering pump or pulley bearing. Progressively got worse, so looked it up on youtube & engine whine videos are widespread - turns out this is a timing chain issue that Nissan knows about, but declined to tell me before the warranty ran out. They have done all the maintenance so they surely heard this engine whine. They even have a bulletin out for the repair of this "defect". the timing chain tensioner shoe is too soft & is wearing out prematurely. This job will cost approximately $1200 & I am currently having the repairs made. I was in talks with Nissan factory reps, & she will not help me any with these repairs, even though it was doing this before the warranty expired, I just didn't know what this noise was. There should be a factory defect recall so all the owners like me could get reimbursed, & so the people nearing warranty expiration could be forewarned to get the repairs done. This is the Q40 V-6 engine.

About 2 weeks ago I started to feel as if the truck was not shifting correctly, soon after that the check engine light came on and I brought it right in to our regular service station. A diagnostic check revealed code P0717 for a turbine revolution sensor and I was told to take it to the dealer. The Nissan dealer did their own diagnostic (no test drive) and found it to be a bad value body, as well as bad timing chain and tensioners, and replacement of all 6 coil packs, along with a few other general findings gave me an estimate of nearly 5 thousand dollars. The 2 diagnostic checks have cost me close to $250. I was in shock and did not have the ability to pay for the repairs up front, so I took the truck to 2 other service stations, one being aamco who specializes in transmissions. None of the 3 other stations found any other issues aside from the transmission. Aamco after a test drive and diagnostic check determined there was an issue but would need to remove the transmission to determine the extent of the problem. Aamco found there to be water being pumped into the transmission, and also claimed it was the 3 problem of this type they had seen so far this month. Apparently the radiator leaks water into the transmission. The fix is a rebuilt transmission and separate cooler for the transmission to assure this won't happen again. At a cost of 3200 to me! this particular aamco is across from the dealer and claims that have done work for the dealership to fix the same problem! I also received a letter back in Oct. /Nov. Indicating a possible radiator problem and an offer of an extended warranty. Nothing was mentioned of the damage that could occur to the transmission! I feel cheated, and in my research have found this to be a very common problem. Nissan should stand by their product and do the right thing by their customers!
