I own a 2004 Nissan Murano sl and have had troubles with vehicle hesitation for quite some time now. It seems to be most present when in stop and go traffic and the engine is warm. After approximately 10mins of stop and go, the gas pedal does not respond for a few seconds and the vehicle suddenly lunges forward aggressively presenting a very dangerous situation. The dealership does not know what is causing this but numerous reports on the internet point to a valve body malfunction.

Uses oil!! I heard a rattle or a chattering noise form the engine on light acceleration. Checked engine oil it was low. Put about 1-1.5qts in. Fixed problem. Next oil change about 1500-2000 miles into the oil change heard same thing. Again low oil repeated last process. Changed oil and again about 1500-2000 miles into the oil change same problem. There isn't a leak one any wear out side the engine must be leaking past the rings and into the cylinders and being burnt. If not caught in time will eventually lead to engine failure which means no power steering no power brakes, caught in traffic, or out in the middle of no wear.

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.

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.
