Problems with 2007 Nissan Frontier POWER TRAIN

Within a few months of purchasing my 2007 nissan frontier, i noticed a disturbing grinding noise coming from behind my dash board. when i brought this to the attention of my dealership, they informed me that if they could not replicate this noise at the time, there was nothing that could be done. afterwards, the noise was only more noticeable. i searched the internet for other people with similar problems. it turns out that the noise coming from behind the dashboard was being produced by a defective clutch. i saw at least 5 to 10 of the same exact complaints and their dealings with service that determined the clutch problem. at this time, i was quite worried about the condition of my vehicle. it is very dangerous to have a defective clutch on any car, let alone a 2 plus ton truck. the ramifications are endless: getting stuck on railroad tracks, at an intersection, crashing into another vehicle... the dealership would continue to misdiagnose or not diagnose the problem. i made several complaints while the vehicle was under warranty. i provided them with evidence that the vehicle did have a defective clutch and even drove a technician around in the vehicle to reproduce the noise that they did not hear. i was informed that it would be covered under warranty by a service advisor. while they had the vehicle, a different person informed me 2 days later that they inspected the clutch, found it to be worn, and that i was responsible for it. i was able to do nothing except pay for the repair to get my truck back. nissan informed me that i should sue, because there was nothing they could do. in conclusion, a defect that was noticed at approximately 2,000 miles ended up costing me over $2,000.00 and potentially my life while the defect was dismissed and misdiagnosed. being that there are dozens of people with the same problem, i would have assumed that this problem would have been rectified without this much turmoil. *tr

Purchased vehicle new with 6spd manual transmission. at roughly 4k miles an intermittent noise was noticed and perceived to be coming from the dash cluster. at 7.8k miles truck was serviced as noise became more prevalent. dealer made repairs to dash cluster by inspecting and sound proofing area. at 9k miles noise had returned and was sent to a different dealer. they too troubleshoot and insulated the cluster. noise continued off and on until a return to the dealer for repairs at 14.5k miles. dealer at this time couldn't replicate issue. after owner of truck performed their own extensive online research the determined the noise to be coming from the clutch and transferring to the pedal on the drivers side. driver returned to dealer with new description of problem and suggesting of throw out bearing inspection. upon inspection dealership said that there was abnormal amount of clutch material on top of throwout bearing and was from the driver's driving habit. they want $1000 just to drop transmission and inspect clutch then more $ to replace clutch. from researching online, this is a common problem for nissan 6spd transmission on the 05+ frontiers and xterras. nissan won't warrant the item because it is considered a "wear" item. many consumer have noticed the noise from the day they purchased vehicle and others have had complete clutch failure at less than 15k, sometimes as little as 5k miles. how, other than factory defect, could this happen? noise was noticed at 4k miles originally. owner is concerned for safety where if the transmission/clutch fails under certain circumstances the vehicle will be rendered useless putting the driving into harms way. i.e. train tracks, oncoming traffic, emergency vehicles. the problem could leave the driver defenseless and unable to maneuver out of deadly situation. *tr

2007 nissan frontier automatic - the truck does not downshift automatically when slowing while climbing a slight hill. this began when the truck was new. the truck begins to jerk when slowing just as a manual trans vehicle jerks when driving too slow while in 4th gear. to force the trans to downshift i would press the accelerator pedal a little more. the dealer said it's normal but i have never experienced this event in any vehicle i've driven and does not seem normal to me. dealer "reprogrammed" transmission- problem still exists--but at different speeds and rpms. the fact there is a repair bulletin indicates nissan is trying to skirt around the problem by not replacing transmissions. *tr

First noticeable complaint is the automatic transmission that does not shift back down in lower gear when climbing a hill. it jerks and shakes at that moment.secondly, the tire pressure sensor does not go off after correcting the tire pressure and keeping it constant. were told the dealer will have to reset,which they did once and it happened again so for 2 years we have just lived with it, keeping check on tire pressure the old way. last but definitely not least for this is the cost factor involved, is the alignment cannot be done due to needing to purchase and have installed 4 camber kits! nissan should have done this already for a $25,000 vehicle!! oh and finally this just happened but the rear passenger power window switch went completely out! *tr
