Hi mate. I knew that Nissan have had a few issues with some of their CVT units.
However I think that generally Nissan’s reliability is not what it once was and I wonder if that’s a consequence of their relationship with Renault.
Toyota have recalled some of their units, particularly in Corolla cars but I’ve it heard of issues with the CVT units on the hybrids.
I’m surprised that they would refuse to cover a repair on a two year old vehicle though, as the warranty should cover the transmission for three years? I could be wrong, but I wonder how many of those owners have had their vehicles serviced outside the main dealer network. If an independent garage are not aware of the specific needs of a specific CVT unit then they could cause issues....such as topping up or replacing the fluid with ATF instead of the particular CVT oil that the transmission to hand actually requires.
I raise this as my old merc is 17 years old and hadn’t been to a Mercedes dealer or even a Mercedes specialist since she was around five years old. I’ve had to sort out transmission faults and other bits and pieces simply as a result of previous owners taking her to independent garages who have no idea what this car actually needs and think that a full service is just an oil change with air and cabin filters thrown in for good measure.
Similarly, the Honda we recently bought for my wife (so I now use her ageing Prius as a daily runabout) had a full dealer history up until late 2017. The independent dealer we bought it from said that they gave it a service so the history was up to date.
Unfortunately all they did was an oil change. When I rang Honda they pointed out that the 72 month service (which is what it should have had this year) is the most major service that this vehicle has....full service with plugs and transmission oil also replaced. I booked it in and had that done, but how many owners would just have left things and been happy with an independent garage changing the oil once a year and being completely oblivious to major additional jobs that weren’t being done, before then complaining to Honda when the transmission fails?
The old Prius has always been serviced by main dealers and personally I think that’s important to ensure that all required maintenance is actually carried out when it falls due. Maybe that’s why it’s never let us down yet.
This is just my personal experience of course, I’m sure that there are some very good independent garages out there, and at times I’ve used a very good old fashioned mechanic I know to trace faults on other vehicles where main dealers couldn’t find the issue. However, in the long list of cars I’ve owned over the years, the least reliable ones have been non Japanese vehicles and particularly ones not previously maintained fully by main dealers.
