Nissan Murano cvt transmission causes delayed acceleration. After 65,000 miles the vehicle did not immediately respond when the accelerator was pushed. It would inch forward then surge. At one time I barely avoided a major accident when merging into traffic and the engine did not respond to the accelerator; then suddenly shot forward a couple seconds later almost causing a collision from the delay. When I took it in they said I needed a new transmission; but I noted that there was not a rise in rpm's when it did not accelerate as would be the case if it was slipping. When I asked about that they said it was probably the solenoid switch that keeps the engine from revving when there is a transmission problem. After checking on the internet I found web sites with many people reporting the same problem. Many said they found it was the switch getting dirty and then shutting down the rpms. I tried a transmission fluid change and it solved the problem for about 30,000 miles then starting doing it again. I changed again and it is once again resolved. Besides the fact that Nissan has a manufacturing issue here this problem is very dangerous. When you step down on the gas and there is a delay it causes you to divert your attention from driving; typically you automatically pump the gas again. Then the sudden surge forward is unexpected and may put you in a place you did not now (after the delay) want to be; especially if merging into traffic.
