#9882 of 10048 CVT Inferiority
May 01, 2013 (10:30 am)
CVT's are terrible 99-cent type transmissions.
I just found out my friends 2007 Nissan with the generic 4-banger motor is going to soon be on its third CVT transmission at about 65,000 miles. The first one didn't last longer than 24 hours, as they replaced his engine and transmission on day 2.
Now again he needs to get it checked as it's making all kinds of noises. He also was told to replace his AC, and recently replaced his CAT converter.
He has paid for the AC ($1,400), but Nissan has the long emissions warranty thanks to CA, so that was covered (saved him about $1,400 too), Nissan obviously paid for the 2nd engine and 2nd transmission replacement when the car was new, and he tells me Nissan decided to warranty these 99 cent disposable CVT transmissions to 10 years or 120,000 miles. So it looks like he'll be covered again.
I told him Nissan has no quality control, his car has lost the equivalent of its brain, heart, lungs, and penis in less than 66,000 miles! Although they've been lucky and had no issues until recently, these 4 HUGE issues are like having 4 different stage 4 cancer diagnosis'.
Even the Neon's ancient 3-speed was good for about 60K miles, the Nissan CVT is averaging 32,500 miles per unit for my friend, who doesn't drive it hard, and only has the meager and weak 2.5 4 cylinder engine.

I doubt that's typical, but that really sucks!

that I ever heard of was one described in Popular Science back in about '59 or '60. The issue they cited at the time was longevity, especially if significant power was involved. For a lawn mower, they were perfect.
I'm going to guess that the 50 year haitus from then until CVTs became production pieces on actual cars had to do with figuring out how to keep all those variable components and the belts (or whatever) from packing it in. Perhaps there is more work to do.

I think their biggest (non-car) use is on snowmachines. Something you really don't want to break down on you.

for the record, it was an amateur mistake of mine to not mention it was an Altima Nissan model, 2007 model year.
I'm sure it's not typical, but I bet given the voluntary warranty extension it isn't uncommon either.
As to how an engine could die on the 2nd day........ I have no idea.
I told him he was lucky. My Neon had to be towed to the dealer on the 2nd day (first morning we had it), and from now on, if that ever happens again, it's staying at the dealer as a lemon law claim .
I've learned my lesson; a bad start often is a signal for worse things to come.
#9887 of 10048 best non-manual transmission for a manual transmission driver.
May 04, 2013 (6:15 am)
how about let's talk about what is our favorite/least-favorite non-manual transmission.
FAVORITE NON-MANUAL TRANSMISSION: GM 4L-80E slushbox, with 3rd & 4th gear TCC/lockup
MOST DESPISED NON-MANUAL TRANSMISSION: any CVT . (minicooper in particular).
let's invite one of the 7 people in USA driving a porsche cayenne with manual shift!
I want one of those, but lately i keep not winning the lottery .

I've only driven 3 CVTs for any length of time---a Dodge Caliber, an Audi A4 and a Mini Cooper, and I hated all three equally. Not a big database, but so far, I am not impressed.

It's the Prius syndrome, as I call it. The main reason people get such high MPG with it is because of the video game type interface that trains you to drive like an 85 year old man to eek out every last drop of economy. You can get caught behind one at a stoplight and have to switch lanes as soon as the traffic starts to move. You can always count on one to be going 5 mph under the speed limit. And it's always one that's holding up everyone in the carpool lane.
Note - that since most Japanese speedometers read 2-5% slow so as to have an acceptable margin to not get sued over it if you run one size larger tires/snow tires/etc, the driver is always going exactly 63 Mph in the fast lane.
The CVT merely takes it another step. Unless you absolutely put the accelerator flat to the floor like a switch, it goes into "I'll drive like my computers tell me to and you'll enjoy it" mode. Great MPG. Utterly soulless puttering around town.

I've driven the CVT in the A4 and the Nissan Murano, and ridden in the late model Altima.
I hated the CVT in all 3. Just didn't like the way it felt slow and false.
My friend said he thought the cool "push button" start in the Altima was made possible by the CVT, which is why he got it.
Funny the things that will sell CVT.
Obviously, he's not a car guy.

I think the only way I'd buy a car with an automatic transmission, of ANY type, would be:
1. My left leg became useless
2. If they'd put a fake clutch pedal in for me to play with.
