    My 2014 Nissan Navara lacks power and has a slow gearbox

    My 2014 Nissan Navara Titanium edition has a lack of power and takes a while to change gear. With my foot flat to the floor, the revs go up but it can't get past 60km/h. It changes gear, the revs go down and speedo goes up over 60. When I reach an incline, the speed goes down. After a while the car accelerates properly. This happens daily. There’s some oil around the intercooler hose.

    This could be caused by any number of things, and an electronic scan of the vehicle will surely reveal some of its secrets and may point you towards the fix. It almost sounds as though the car is going into limp-home mode when you first start driving it, but then reverts to proper operation once the engine has warmed up a little. But this could also suggest a turbo-boost leak somewhere in the system that is closing up and disappearing once there’s some heat built up.

    If there’s oil around the intercooler hose, you may have oil in the intercooler itself. This can cause all sorts of problems and is often caused by a worn turbocharger. I’d definitely be having a close look at the turbo unit, checking for wear and damage as this could be the root cause.
