I hear ya, and I've done a lot of searching and reading on the subject of CVT's over the years too, but what I was disagreeing with was your statement "they frequently have problems". This may be a percepton but the actual numbers don't support this. Look at published reliability ratings, specifically for the CVT component and you'll see that they don't frequently fail. And don't get me wrong, I'm not biased here, if anything I was like you and biased against the CVT until I really studied the numbers and put perceptions aside.
And I believe that CVT's are becoming more widely used in some cases, not less. Most hybrid vehicles are using or plan to use CVT's.
The conclusion I've come to is that the CVT is AT LEAST as reliable as a conventional transmission and in a lot of cases it is superior, depending on the specific manufacturer you're comparing too - basically CVT is middle of the pack and to be fair conventional tranny's have lots of problems too. A lot of the bad perceptions of the CVT come from early "trouble spots" such as the 2003 first production Murano - this CVT was very bad and the complaints were well documented.
Here's the key point I'm trying to make, if today you research "CVT troubles" you'll get a lot of 03 Murano hits because a lot of people complained. But you'll see very few later model Murano, Rogue, Cube, Altima, Sentra etc. problems because the current CVT design is quite different and vastly superior.
If you search "tranny problems" for any other manufacturer you'll get a lot of hits, just like for the CVT. I had a friend who purchased a 2007 RAV4 and his tranny was replaced 3 times before he finally traded it in and who knows what eventually happened to that vehicle.
My questions is, based on my story and other horror stories of bad Toyota RAV4 transmissions (a simple google search will reveal a long list of complaints against the RAV4 tranny), should we conclude that conventional transmissions are "bad" and should be avoided?
Again I'm not biased, I don't work for Nissan and I'm not really brand loyal, I buy from whoever gives the best product at the best price. But if you put perceptions aside and just look at the stats, Nissan's and the CVT are never below average and in most situations are above average in reliability. There are probably some better products out there but there are also those that are worse, I have cousin who works on Ford tranny's all day long, they have a very high rate of trouble.
