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.

Frontier 6-cyl

  • 43,600 miles


My 2007 Nissan Frontier with 4.0 V-6 engine has 43,600 miles, and it making a knocking / banging noise, I contacted Nissan North America to file a complaint because the vehicle only has 43,600 and had all routine maintenance as scheduled. They sent me a reply back stating "a review of our records indicates that the above-referenced vehicle is not currently involved in any recalls or service campaigns. In order to look into possible assistance, a recent diagnosis by a authorized Nissan dealership is required. So I contacted my local dealership to have it diagnosed. And dropped off my Frontier at my local dealer on Monday evening (1/30/12). Tuesday afternoon (1/31/12) the service manager called me and said that the knocking is from a lower piston rod, the timing chain and components are worn out, there are metal shavings in the top of the engine, and it is also blowing oil into the air intake. Basically, the engine is completely shot!. the cost to replace the engine is $6,000 not including labor. He then went on to tell me, that he called Nissan North America and informed them of what he found so far, and said that according to company policy, he needs the vehicle "a few more days" to further investigate if there is in fact a defect, because more information is necessary to determine if it is covered under warranty. It is obviously very upsetting that this vehicle only has 43,600 miles and the engine is shot, not to mention, now I am without a vehicle. Since there are so many complaints and problems with this 4.0 V6 engine, there should be a recall to replace/repair the defective parts, or atleast be covered under my extended warranty at no cost to me. It is my opinion, not only is this a "mechanical defect" it is also a "safety issue", due to the fact, while driving on the hwy, the engine can fail, causing loss of control of the vehicle.

Frontier has developed a buzzing/whining sound that is a well documented and common timing chain problem this is not just my vehicle, but with most of Nissan's models since 2005, which is when they redesigned and began using the 4.0L V6 engine in these vehicles. Nissan recognizes the problem in tsb's ntb 07-42A, ntb09-128, and ntb07-042C, but refuses to issue a recall and if your warranty is up you are on the hook for the repair. Ordinarily I would understand that, as all parts wear out, but in this case, the failure is common and prevalent in multiple Nissan models from the same time period, suggesting an engineering design defect in the engine and should be recalled. Frankly, if this was an immediate life safety issue, a recall would have been issued in light of the numerous failures and number of models involved with this same problem.

Excessive rust on oil pan bolts with rust spreading from bolts to oil pan. Excessive corrosion (white, powdery looking coating) on undercarriage bolts. Unexpected rust on hose clamp attaching filler tube to gas tank. 2007 Nissan Frontier, crew cab style, 4X4, SE model. This vehicle was purchased new in Virginia and driven in Virginia. Contacted dealer with photos of the rust and they inspected and claimed to have forwarded information to regional service director. After no action, called 1-800-nissan1 and they directed me to return to the dealer and assigned a case number. Dealer supposedly documented the rust and again submitted to regional service director (9/6/2010) - but I have not received a promised followup phone call. Two additional calls to 1-800-nissan1 (directed to phone box when I provided the case number) have not been returned.

  • Automatic transmission

The contact owns a 2007 Nissan Frontier. When the contact attempts to start his vehicle after it has been parked for a while, it begins to smoke. He stated that this is a brand new vehicle and the failure has been occurring since it was purchased. The dealer and the manufacturer stated that this was just the nature of the vehicle and failed to mention if it was due to a manufacturer defect or design flaw. The failure mileage was 2 and current mileage was 3,000.
