I have a 2015/6 Outlander GX4 2.3 diesel automatic. Owned from new and regularly serviced by Misubishi. Just recently there has been some slight jerkiness in the driving. Mostly, it stops after a few miles but can be intermittent later.. The weather here in East Sussex has been very hot lately. I am concerned about the clutch drive (whatever it is called in an automatic) CRV ?? etc. Is there any remedy that I should look at first before thinking about very expensive repairs.
