I am in the Bay Area myself and I regularly get the overheat warning on my 2014 Zero SR during the northbound climb on I-280 from (California 92 intersection to California 35 Skyline Blvd exit). Just doing highway speeds (75-80 mph), pretty much at any ambient temperature. This is a demanding climb at those speeds, so I am not very surprised.

From my experience, the QuiQ charger will initially draw up to 9.5 amps (110V) for an hour or two, then settle on around 7 amps. I was not able to charge my 2012 DS when I had both chargers on the same 15A circuit (I tried). 20A circuit was doing fine.

Zero SR onboard charger draws about 11.5 amps initially then it stabilizes at around 10.5. This trips the 20A circuit breaker if I connect both chargers at the same time.

6000 on my 2012 DS
300 on my 2014 SR to date.

Update on my cut-out problem. I dropped my 2012 DS ZF9 at the dealer just before Thanksgiving. They apparently shipped the bike to Zero and it came back yesterday. I also got a recall notice via certified mail (recall number: 13V-635, dated 1/15/14) for the cutout problem. Going to pick up my bike tomorrow and see how it performs.

Edited to add: it performed ok, no cutouts, but I decided to trade it in for a 2014 SR. OUCH, my wallet.

Any updates from people having issues?

I noticed that my "glitch" happens when I walk the bike backwards (i.e. from a parking spot or garage) while the "ignition" is on. The bike then emits noises from the engine and starts having problems shortly thereafter.

For the last 2 weeks or so I have been careful to turn the bike off with the key if I had to back off somewhere and didn't have any recurrence of the "glitch". I have put about 400 miles on without a glitch. It might be a coincidence though, I am not sure.

This is exactly what I am experiencing on my 2012 DS ZF9. I had both dead throttle and the power cutouts while moving. Reset cures it sometimes but only temporarily. The glitch has been happening with increasing frequency since about late February. I have 5700 miles on the bike now.

Last Friday it took me about 7 times to get the bike moving. Then I got the "thunk" and lost power in a tight curve and almost fell. Also, sometimes the throttle is completely dead and sometimes applying throttle while standing still will induce a slight *backwards* motion. Sunday, I lost power four times on the road and in fact, it has became so bad that I was wondering if I make it back home.

The bike is always fully charged and garaged, it was never in the rain. Heck, I didn't even wash it since new ;-)

My 2012 DS ZF9 has developed an annoying glitch. I feel and hear a little "thud" sound from the motor and all of the sudden all the power is lost. Applying throttle even causes a slowdown if moving; applying throttle while standing still will induce a slight *backwards* motion. The usual reset with the ignition key takes care of that glitch usually, however I needed to do that at least 7 times Friday to get moving

Saturday, I lost power while in a tight curve and almost fell.

Is this a known problem? Is there a solution?

And the tires were installed today, no pictures though since the bike is now at the dealer, awaiting new charger installation.
