CVT in my beloved 2010 Cube is about to die. The car has just under 30k miles. One morning I started the engine, begun switching into drive and when I came to reverse there was a dull bang in the transmission and car lunged forward once. After that it would not drive in reverse but after 5-6 ignition cycles it 'fixed' itself, still I have following permanent symptoms now:
1) When in idle or neutral there is a noise as if there is a bad bearing (which it probably is)
2) When I switch from neutral / park into drive / reverse and back there is audible 0.5-1 sec scratchy shift sound as if something is moving over sandpaper.
3) Once in drive or reverse transmission sounds absolutely normal in idle
4) When driving in reverse the "bad bearing" noises reappear
5) Normal driving is fine, no abnormal noise, acceleration / shift is good etc.
I am in Europe and Nissan Europe refuses to honor extended CVT US warranty for 2010 cube (No class action suits, Nissan / Renault can relax and sell broken cars). I have gotten a 'generous' offer of 9k$ for repair and fighting corporation now but if I will not succeed I would like to research other options besides scraping the car.
What went wrong down there? I have a feeling some bearing(s) lost ball or two....
If it is "just" a bearing, can a person with little car experience but two hands and a nicely tooled workshop attempt to replace it or is that a lost time?
The car is stationary now, I am not driving it but how long would you guess would it take this tranny to fail if I flush it to remove debris and continue to drive without repair?
How likely is some potentially catastrophic failure that would endanger the health / life of the driver?
