So there is the official recall for the 2012 S/DS "glitch" motor controller issue. No mention of the 2012 XU though.

Guess what happened while commuting this morning... odd noise/pulsing for about 1KM, I shut it down and inspected for anything odd, powered it back up and continued, then 1KM later the power cut out completely while riding through a corner. I've notified both Zero and Transport Canada.

It seems like one thing after another with this bike. Has anyone else experienced the "glitch" with an XU? I think vchampain mentioned it...

I think the original glitch was thought to be specific to the sincos encoder on the dual-rotor S/DS bikes. The PMAC motor on the XU is single-rotor.

Can you describe the noise/pulsing effect you saw? That sounds very much like the glitches I've seen on my S.

Do you know if the controller firmware has ever been updated?

[craigq]

Hi protomech! The bike's controller firmware hasn't been updated, whatever it shipped from the factory is what it currently has. The BMS was replaced/updated a couple of weeks ago, but the dealer only had the power pack, not the bike.

I'd describe it as an audible noise (can't describe further as I normally ride with earplugs, I'll describe it better tonight w/out earplugs) that coincided with what felt like very minor output power fluctuation even if the the throttle was kept at a constant position. That went on for a little bit, then I was coming out of a corner and attempted to apply throttle when the motor died.

Has your bike been repaired yet?

[protomech]

Yeah, that sounds pretty much exactly like what I've seen recently.

The last I heard was the motor had been shipped back to Zero, and it was expected to be repaired quickly. I need to follow up on that; I'll post an update to the 2012 glitch thread.

Spoke with Zero customer service, they advise getting the bike to the dealer, with it requiring anything from firmware upgrades to possibly a new motor. We'll see how long this one takes. Flatbed towing fees are going to be awesome...


EDIT: commute home was uneventful. Motor sounded normal, no odd noises.

Hello !

Yes I had the glitch : many times, the motor stopped either after a road bump, or after a few km, without clear reason. After stopping and restarting it worked again, but after the motor stopped while lane switching, I took the bike to my dealership. The XU is currently repaired, they sent it back to Netherlands. I still don't know what happened. In the meantime, i bought a Zero S 2013.

I've had that problem.. in fact I rode all of 14 days on my 2011 xu since May.  The rest of the time has been spent trying to get it fixed.  I'm about to consider a 2012 xu, but if that is still a problem I'm sincerely worried.  I wonder how many 2012 xu owners have not had a problem with this?

[vchampain]

If you go for a 2012 XU, ensure the seller has it sent to the factory and fixed before you get it !

[craigq]

Latest news from Zero is that it requires a firmware upgrade...

Hello everyone. I have 750kms trouble free on my 2012 xu so far. When did you guys experience this issue ie: at what mileage?

[craigq]

Around 1800 KM. Mine's an early build, one of the 1st XU's in Canada for 2012.
