Failure of the alternator belt tensioner bracket. The belt tensioner broke on the 2004 nissan murano, causing it to cut the coolant hose to the oil cooler. The belt tensioner, coolant hose to oil cooler, and belt had to be replaced. I belong to the nissanmurano.organization discussion group ,and several other people were having the same problem.

Idler pulley and bracket design default. I just took my car in after an all of the sudden clanging noise - at 35,000 miles. I was told by authorized dealership that I required a new idler pulley and bracket. Apparently it was broken. I believe this is a design default and should be looked into. I have heard many people complaining of this same thing. I ended up paying $99 for labor, $69.50 for the pulley, and $25 for the bracket. This part failing at 35,000 miles is unacceptable.
My wife and I noticed that the heater blower was only blowing cold air when turned to high. Also, the temperature gauge was showing anywhere from extremely hot to very hot. Upon inspection of the coolant level reservoir it was showing full. However, the radiator was empty and took 3/4 bottle of coolant to refill. Then I noticed that there was a puddle of coolant that had formed on top of a bolt. We also could hear a noise from engine compartment. Upon investigation noticed idle pulley was vibrating and make the sound. I investigated online at www.nissanmurano.org for similar problems. I found a series of reports that the bracket that holds the idle pulley was broken. I had the dealership inspect the vehicle and it looked to them like the pulley bracket was broken. Upon examination of how the bracket broke seem that the bracket is under-designed. The crack seems to indicate that the bracket broke by bending fatigue. This idle pulley tensioner had then severed the coolant hose. The failure to this idle pulley could lead to an alternator not providing energy to the car and even more serious consequences.
Alternator adjusting bracket - jan 29, 2007 today, I had to have my 2004 nissan murano serviced due to a coolant leak that I noticed. When looking at the vehicle, entire underbody was filled with coolant and no coolant remained in the resevoir. The dealer serviced the vehicle and documented the issue as the alternator adjusting bracket having broken and rupturing the hose, fan pulley and the power steering belt being negatively impacted. After speaking with the service tech., there have been multiple times that he has seen this issue. With an obvious repeating issue in the vehicles, the severity of damage to the vehicle (bracket breaks, alternator loosens in hood and damages surrounding mechanisms, or occupants (operation of vehicle not ideal with bracket broken, impacting surrounding mechanisms (power steering belt, fan, alternator, coolant system) that could result, and the customer dissatisfaction of having this issue and incurring the costs to repair.
Twice in the last two weeks my 2004 nissan murano has had a complete computer failure, resulting in loss of both steering and brakes. The computer failure only occurs when turning the car on. Turning the car off and on again appears to "reset" the computer. I have taken the car to the nissan dealership and have been told that because the problem did not occur in their presence, there was nothing they could do about it therefore there was no repair or replacement of any parts. Because there is no specific "event" which leads to this problem, I am left to drive a car with a serious malfunction which may in turn cause an accident resulting in bodily injury to myself or others.
Having issues with engine mounts. Had one replaced last november and getting two more next week. Purchased under extended warranty so everything is covered but concerned about when warranty expires. Want to know if others are having this problem.
Events leading to failure: replacement of alternator due to product recall failure: coolant hose location: where coolant hose touches outside edge of idler pulley adjustment nut. What was done: vehicle will be taken to dealership for repair. Assumption of failure: vehicle was recalled to replace alternator. When serpentine belt was tightened, coolant hose weakening occurred. Visual observation: coolant hose is pressed against adjustment nut depressing it 1/16-3/32 of an inch. This combined with vehicle engine natural vibrations a hole in the coolant hose occurred. Result of coolant loss: ultimately, engine failure could occur resulting in loss of vehicle control resulting in serious injury or death due to loss of coolant from failed hose. Possible solution: nissan will repair or replace idler pulley adjustment bracket and insure proper adjustment space between the idler pulley adjustment nut and coolant hose.
Dt: the contact stated while driving 30 MPH, the vehicle lost power. It was muscled home from the scene of the incident and towed to the dealer. The dealer determined the cause of the vehicle's lost of power was due to internal failure of the throttle chamber assembly. To repair the vehicle the thottle chamber assembly was replaced. Right before the incident, the vehicle's check engine light illuminated.
Heard noise from engine compartment. Upon investigation noticed idle pulley was vibrating and make the sound. I investigated online at www.nissanmurano.org for similar problems. I found a series of reports that the bracket that holds the idle pulley was broken. I disassemble the pulley and found the bracket broken. Upon examination of how the bracket broke seem that the bracket is underdesigned. The crack seems to indicate that the bracket broke by bending fatigue. I saved all the bracket pieces and I going to evaluate under a microscope. The failure to this idle pulley could lead to an alternator not providing energy to the car and a more serious consequences.
I have a 2004 nissan murano I purchased the vehicle new at 3000 miles the engine blew and nissan repaired it and spent $14,000 to repair. Now I have been contacting nissan and telling them that my tires are bald in the inside from the engine being taken out because they did not align it right and I have a foul smell of antifreeze in the vehicle and that the engine is knocking again. But instead they tell me that there is nothing wrong with the vehicle. I had spoken to someone at nissan of staten island and he was very nasty and even told me not to bring my car there. I need help what can I do please help me I want to give this car up I don't want the problems.
