The problem is with Nissan continuously variable transmission (cvt), in particular my 2010 Nissan Murano. When the car is driven in hot weather for more than 200 miles in heavy stop and go traffic, the car will not accelerate. No matter how far the gas pedal is depressed, the car will slowly accelerate from 0 to 15 mi/hr in excess of 10 seconds! once the car is moving above 15 mi/sec, normal acceleration resumes. This problem is so prevalent, Nissan Murano owner's call this "limp mode". if you search google.com for Nissan cvt issue or limp mode, you will get thousands of complaints. Nissan knows this is an issue but have not figured out exactly what is causing this problem. Their genius idea is to extend the cvt warranty to 100K miles instead of fixing the safety issue. This has occurred to me two times once traveling from Washington DC to nyc in April, 2010 and DC to outer banks, nc in July both under the same conditions (high temp and bumper to bumper traffic). I've taken my car to the dealer both times and the response was we can't fix it because we can't duplicate the symptoms or never heard of such issues even though there are tsb related to this issue for 1st generation cvts. Supposedly Nissan fixed this issue in 2nd generation cvts (2009-present models), but I have the same issue and believe Nissan has failed to fix the cvt design flaw. This is a real safety hazard! although I did not get into an accident, however came close multiple times because I had a difficult time merging onto high ramps, or even pulling out of intersection to merge with traffic. My family and I were almost rear-ended multiple times in outer banks just making turns. Please force Nissan to address the cvt design flaw as all their vehicles are being replaced with such faulty transmissions.
