I've Nissan Sentra 2014 1.6 cvt 170k kms [105k miles] driven. I've had an issue with cvt while accelerating from full stop, a jerking at around 20kmph which feels like clutch is disengaged for a second and then suddenly reengaged . When I took it to nissan they advised cvt fluid flush &change and luckily the issue was resolved. Now the issue I'm facing is with a slightly increased rpm. Originally at 120kmph the rpm was 2k but now it goes up to 3k to 3.5k at the same speed. Before the cruise was silent at 120kmph now there is noticeable engine noise inside the cabin. The car was always serviced with nissan but now they are recommending cvt replacement. Any advise will be highly appreciated.
