nycarguy: I think some earlier Altimas with the cvt did have trouble. Specifically the belt, which as you might imagine has big stresses placed on it, could wear out. As you know, it's not a regular belt, but a very high tech "super belt." I think the Nissan CVTs are now more reliable.
Honda has developed a new and supposedly better belt for its new earth dreams CVT. Here's a short link to a Honda site with a press release about it:
"....Key features of new CVT for midsize vehicles
The newly developed high-efficiency electric oil pump, high-strength belt and exclusive CVT oil raise transmission efficiency to enhance fuel economy.
The wide ratio range offers cruising with enhanced torque in the lower rpm range, thereby enhancing fuel economy. At the same time, the wide ratio range increases drive power during off-the-line acceleration to help realize an exhilarating and sporty driving feel."
Honda's "G-shift" design and software apparently much reduces the acceleration lag that you can get with Nissan's cvt. In other words, if you floor it in a 2013 Honda Accord cvt it's supposed to respond pretty quickly.
Honda has probably spent a billion or two dollars developing this transmission. The belt on the new Honda unit is supposed to be something of a breakthrough for strength and durability. Right now I think they are making the belts in Japan, but they are about to start producing them in Ohio.
I think the Honda CVTs will be quite durable, but I would probably buy an extended warranty just in case....

While that itself impressed us, what's the most noteworthy in the Accord's CVT is how quickly it can respond and bring revs up when needed. For instance, a number of CVTs (including the one in the 2013 Nissan Altima, surprisingly) will feel completely flat-footed and off their game if you roll around a corner at 15 mph with your foot off the gas and then accelerate at full throttle. The time to tap into full thrust is delayed for a surprising time. But in the Accord, it very quickly raises revs all the way up to the Accord's 6,600-rpm redline. Pull off the same test, dipping into half throttle out of the corner, and it very quickly finds the right ratio for the throttle opening—feeling a lot like downshifting and with no slow, muddled ramp-up.
How did Honda achieve this far better (we think) CVT calibration when rivals like Nissan have been working at it for so long? According to the project leader, Honda's CVT isn't much different in the mechanical design, but Honda put a lot of time into oil pressure control and electrical systems, along with the control software.

Appreciate the info and enthusiasm for Honda you provide but could you bold or italicize and add quotes when you are directly cutting and pasting. Really would like to differentiate between your actual comments versus copying of reference material. Tks.

Sure. Usually do add quotes but forgot that time...

My wife had a black 2004 Mazda 6 Sport-wagon V6. I drove a 2003 Mazda Protege LX, simply because I had a 40 mile each way commute and needed the fuel economy over space. The wife had both the girls and worked full time so she got the sweet ride.
Both cars drove awesome, but there were quality problems. The 6 kept having A/C problems and was plagued with wheel bearing issues, bent rims, and occasionally refused to start for no apparent reason. We found out later that the battery was bad. Our roads here in Northern VA are really good so I can't attribute the wheel issues to potholes, frost heaves, and all the other rust belt/great lakes area road problems. (no offense..I am from Buffalo).
The Protege' did NOT have ABS, but DID have summer tires. OMG. I almost died in that car. It hydroplaned at 60 mph on interstate 95 at the "mixing bowl"....slamming into two walls. Can you say med-evac? My first helicopter ride.
I think Mazda makes great cars, we probably had bad luck. I think I will pass on Mazda as long as I live though.

' My first helicopter ride. '
Really glad it was not your last...
Medevac = really bad, typically.......

Scary story! So glad you made it through ok.
Cars are significantly safer than they were even 10 years ago, and that's a good thing...

I had my right arm broken in two places, a broken rib from the seat-belt, lacerations of the face (looked worse than it was)...and I got to have black and blue marks in the shape of a seat-belt across my chest and gut.
Saved my life. The car still ran afterward. They drove it onto the back of the flatbed I was told.
I so didn't even ask if the car (Protege')had ABS when I bought it. The EX had it, but the LX and the lowly DX did not. I mean come on....it was 2003!
So much for making automotive assumptions that all cars have our safety as priority one.
