2003 Nissan Murano: engine overheating

Filed Oct 11, 2016 · Acceleration, Engine · 108,000 miles · ID

Purchased this vehicle in 2012, used- bag an having issues immediately, including , no heat, stalling, windows rolling down on their own in winter- returned it to the dealer and they kept for 1 week, said there was nothing wrong except the fuel pump. We replaced it and trouble continued. Contacted nissan and they said to take to dealer for diagnostic, a certified nissan mechanic now looking it over and claims there is nothing wrong, we have thrown so much money into trying to get it to work. Overheats and can not climb even the smallest of incline without overheating, the nissan company wants us yo pay for all the testing they require, we have been paying for a vehicle that is not drivable or reliable in any way- after 4 years there is still no answers as to why it will not run properly, so disappointing yo purchase a vehicle that looks good and is comfortable, and has become a lawn ornament that still has a large balance to pay- does nissan produce things they walk away from laughing at the consumers for purchasing a non reputable vehicle. So aggravating to be told it is our problem, feel as though I could have gone to the junkyard and purchased a wrecked vehicle and had better results, we just want to be able to depend on a vehicle we purchased without the run around. Sounds like they made a problem car from the other comments on how others have experienced the same issues, without any answers. The unexpected stalling and overheating and no production of heat in the vehicle has been issue since purchasing in 2012 to now 2016, just would like some sort of answers.

I own an '03 nissan murano. Since 114k miles, I have experienced stalling following idle. The problem usually occurs when the vehicle is very warm (not overheating). After sitting idle for a few minutes (I.e. At a redlight or stop and go traffic) when I press the accelerator, nothing happens for a few seconds. The RPM's do not indicate any change. And then all of a sudden, the vehicle "realizes" I am pressing the accelerator and takes off at excessive speed/rpms. The problem has put me in very dangerous situations such as when I am trying to make a left hand turn across traffic and suddenly stalls. Or like the first time I experienced the failure, I was trying to pull onto a major highway. By the time my vehicle decided to go, another vehicle was approaching in the lane I was trying to turn onto and I had to slam on my brakes to avoid pulling out in front of the oncoming vehicle and causing a wreck. Several vehicles were behind me waiting to get onto the same highway and were very aggravated I was holding up traffic since my vehicle was stalling. The problems occurs as regularly as I sit idle in traffic or get into a congested traffic area. Every single time. After reading hundreds of early year murano owners are having the same problem, I feel nissan should recognize this as a defect and take responsibility for this costly danger. I have read that many have had to replace the entire CVT transmission and that nissan is often misdiagnosing the problem. A code reader indicated my tps sensor was bad. I changed it with barely any noticeable changes. Later a dealer's code reader said I should replace the cadillac converter. After that pricey repair, I still have the same problem. Extremely dangerous.

I have a 2003 nissan murano. Yesterday as I was pulling into the driveway, I noticed it was overheating a little. I immediately called the repair place and had them come and take it to be serviced. They just called to inform me that the radiator is cracked and the thermostat housing needs to be replaced at a total of $1144.60. T here are 75000 miles on this car and it has always gone for scheduled maintenance, oil changes, and everything required to keep it running optimally. Have read about radiator cracks from several other murano owners, and knowing the other problems I have had with my lemon of a car - they had to replace the alternator 3 times - I would seriously believe that there are going to be more and more problems with the radiators cracking on other vehicles.

Heard noise from engine compartment under low RPM range. Took vehicle to local nissan dealer for inspection of problem and mechanic could not duplicate but was advised by shop mechanic about worn drive belt. Vehicle is @ 34,000 miles. Upon investigation at home from top of engine bay, I noticed AC/alternator idler pulley was vibrating and rotating of axis to the crack pulley. 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 and causes cutting into the adjustment arm and causing the noise (eventually failing). Returned vehicle to the dealer and informed dealer of idler pulley problem researched online and request belt service. When mechanic removed the belt, the idler pulley assembly was found to be broken. I believe this is a serious design issue and nissan should provide a better design and recall a $16 part. Potential issues of failure of pulley: 1) nearby vicinity of the radiator coolant return hose can cut by broken bracket and can cause engine to overheat. 2) could lead to an alternator not providing energy to the car and a more serious consequences. *tr updated 01/11/08. *lj updated
