I notice a slight but noticeable occasional misfire/stumble at idle. Does anybody else have it? I'm not thinking it's a problem, but maybe a characteristic?

This is specifically with a manual transmission in neutral, fully warmed up. not sure if the CVT would cause it to act the same sue to potentially different load on the engine, but the question still applies.

I've heard of people misfiring and are unable to accelerate at all and both cases were with touring model, haven't heard of it stumbling yet.

It shouldn't really stumble at all. I have heard of other new cars doing it but it's usually a cam positioning sensor acting up on the odd occasion. If you aren't stalling out or getting any serious shudders, you should be good though

I wonder if it's a sign of things to come, or if it will just always be like this. No issues with driving or accelerating. Just a slight bit of a "rough idle" for lack of a better term.

It will be interesting to see if this thread grows as more people buy these, especially the 6MT.

Can you correlate any thing, like with clutch engaged/disengaged? Or totally random? Engine should not stumble or hesitate when idling...does the blip show on the tach?

My LX idles perfectly smooth, but when you roll the windows down you get a real droan from the exhaust and its not a steady droan its all over the place. You would think the cars not running well at all, but its all in the exhaust, the motor is just purring, no vibrations, shakes or misses. It's like the exhaust is too open and theirs not enough back-pressure at idle! P.S. this is a good thing it means theirs more room to drive air down it's throat. Could you be picking up on this unevenness in the exhaust note?

Modern engines throw misfire codes even if you can't detect them, so I wouldn't expect it to be a misfire issue unless you have a check engine light.


Cold start misfires are very common with direct injection motors after a bit of miles on them, I wouldn't expect it on a new motor this soon.

Take advantage of that fresh warranty while you can.
That's just about the biggest take away from any advice you can get from anyone when it comes to owning a new vehicle.
These have so many things going on that you have no choice but to go that route just to protect your wallet and not be sucked into more years of ownership just to feel like you got your $2k+ worth of maintenance out of pocket.

A video would be ideal but warranty definitely should be stepping. Something is clearly wrong.. a stumble on cold start would make sense but not a misfire.
