    Power loss at upper rev

    Nissan Nissan Advice Nissan Navara Nissan Navara Advice Nissan Navara 2007
    I generally like my 2007 Nissan Navara, but I'm not happy with the fact that it loses power at the upper rev range. It's like it goes into a limp-home mode. There are no warning lights, just a loss of power, but you can turn the vehicle off and back on and all is good. This has happened on and off from near new. My dealer cannot find the cause, but they say it might be the fuel suction valve. They can replace it for about $850, but it might not fix the issue ether. It seems to be a global problem, but Nissan Australia doesn't think it is an issue. For me it is a very serious safety concern, as it can occur when towing up hills or at worst when trying to overtake other vehicles. Do you know anything about it?

    I can understand why you would think it's dangerous. We haven't had any other reports of this issue, so can't say that it's widespread as you claim, but it's something that needs to be addressed on your vehicle at the very least. It would not appear to be a problem of the vehicle going into a limp-home mode, as you would expect a warning light to come on. That said, switching the car off and on again usually reboots the computer and eliminates the problem. I would suggest it's a fuel supply problem, perhaps the pickup that the dealer is suggesting, or even the fuel pump or injectors.
