Problems with 2007 Nissan Frontier ENGINE AND ENGINE COOLING

I had been noticing my automatic truck shutter before thumping into gear months before i actually took the truck into the nissan dealers shop for analysis. when they inspected, i was told my transmission had been damage due to contamination by engine coolant and i would need a new transmission. the source of the contamination is a cracked atf line that runs through an engine coolant chamber in the radiator. this defective part and design came directly from the nissan factory. nissan knew about the defect and failed to notify the consumer or replace the failed transmissions @ no cost. please advise of any recalls and results from the investigation. *tr

My transmission failed due to radiator coolant mixing with my transmission fluid. nissan knew about the factory defect but failed to notify the consumers or replace the transmissions. nissan was involved in a class action lawsuit and increased the transmission warranty to 10 years or 100k miles. but they required the customer to provide a co-pay of $3000.00 (which is ridiculous). however i noticed symptoms of my truck shuttering and thumping into gear around 95,000 miles, my vehicle had appx110,000 miles on it when the nissan dealership officially diagnosed the problem. furthermore, mileage should not matter because this is a "factory defect". i bought my nissan frontier new in 2007 and it was only a matter of time before the transmission failed due to the "factory defect". please inform me if there is any recourse/recall for this situation. thank you. *tr

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. *kb

At 7600 miles i hear a noise on the engine and check engine lights came on and gas gauge star reading empty went was full i took to the dealer they told me the noise was coming from some where in the engine they never told me was timing,chain,i took to a local repair shop and they found out that timing chain was the problem ,the check engine light at the dealer told me the was the that the reason for the gas tank read empty was t due a gas module. *tr

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 $6000.00. 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. *tr

Tl*the contact owns a 2007 nissan frontier. the contact stated the radiator was cracked causing the anti freeze to spill into the transmission which ruined the transmission. the dealer stated they had to replace the transmission for $7,000. there were no recalls or warranties related to the failure. the manufacturer was reviewing the case and will get notify the contact of the findings. the vehicle was not repaired. the failure mileage was 91,000.

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. *tr

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. *tr

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. *tr
