Car started to jerk forward when I was 2 hours into a 3 1/2 hour drive. This occurred when I came upon heavy highway traffic, and had to idle in traffic. Temperature outside was about 98 to 100 degrees, and the car was not overheating (no smoke/temp gauge was normal). Later on into the drive, the car began to jerk forward and cut out at stop lights. I had to turn the car off at the stop light then turn it back on to get the car to drive. Later on in the day, the car got progressively worse. It started to make a laboring/whining sound and would not accelerate beyond a particular speed or respond to the gas pedal. Eventually, turning the car off then on did not work. The car would drive about 20 feet then would not accelerate, then coast to a stop. I had to be towed from philadelphia to virginia because there were no nissan shops, nor auto shops open during that time of a saturday. Sunday would not have been a business day for mechanics either. I live in virginia.

On the morning of 9/15/07 when starting the vehicle I heard a belt squeal. When investigating the belt squeal, noticed coolant leaking from engine compartment. Upon further investigation noticed the idler pulley bracket was broken causing the coolant hose to rupture from rubbing against the idler pulley adjuster. All in all, we had to replace the idler pulley, pulley bracket, and the coolant hose.

Alternator adjusting bracket - 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 reservoir. 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.

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.
