Acceleration- no response

Try to repeat it on a empty stretch of road (no need to try and pass something) and literally count off "one thousand one, one thousand two, one..... ) or a passenger with a stop watch and see if it truly is three seconds.

 

No mention of location, were you possibly on an icy snow covered or bumpy road?

 

My guess... is you depleated the HV battery while following slowly and didn't have the power to pass. Did the engine rev loudly?

 

What did the speedometer indicate?

How often do you dropped the pedal to the floor prior to this?

The system is not supposed to respond with a "shift down, high rev" type feel. The initial power boost comes from the electric motor, which will basically be undetectable. The engine will then join in, but smooth from the CVT. Redline itself is lower than with traditional vehicles too.

 

Interestingly I had something similar happen tonight. Was waiting outside the store for my son to drop off a video (10min) and the SOC dropped to 3-4 bars. As I was going up a slight hill to get out of the parking lot, I laid into the accelerator and pretty much nothing happened. The engine started but did not rev up. I slowly proceeded up the hill. I didn't have enough room to floor it to see what would happen, unfortunately. It did seem odd.

 

ECO mode. Got the car 7/09. First time I really noticed it.

 

I like to stomp on gas from time to time. Usually there is no delay. Rarely, 0.5s delay happens. This is nothing compared to Audi double clutch tranny that can sit and doing nothing for 1-2 seconds when one trying to move very fast. I would say 3 seconds sounds life threatening if really that long.

 

Seriously? 1, 2 or 3 seconds delay? That can't be as-designed, can it?

 

I had a similar incident last week. In my case, I had started the car a minute or two prior so the ICE was warming up. I took it slow (under 20 mph) through my neighborhood and had to turn onto a main road with a 35 mph speed limit. The car acted sluggishly for 1-2 seconds by my guess but then the car accelerated as normal. Temperature was about 25 F, night time, clear roads with little or no incline. I chalked it up to the battery and ICE being cold, pun intended.

 

This is normal during the warm-up stages.

In my case last night, and the OP situation I would imagine, the engine was completely warmed up. But in my case, I was sitting for 10 min and that might have caused it to fall back in the stages?

 

The speedometer reveals the true situation, not what is felt by foot, back, or bottom. Having 2 sources of power and a transmission without gears provides feedback different from traditional expectations. Watch the numbers.

 

I have one more idea for what happened to you.
Above you cleared that it was not a problem with depleted battery, cold battery, eco mode and warm up stage. But I have one more idea, that come from other threads. If you drive quite slow and push gas pedal to the metal (in normal and pwr modes) it will give all available power to the wheels. If there is something slippery under them (sand, ice, mud) electric engine may run out of sync. If it happens car losts all the power, resyncs engine and then revvs up like normal.
Meanwhile TRC icon should blink. If I do it on snow my car needs about 2-3 seconds to recover. Maybe that happened to you?
