Gen II Acceleration apparently declining

Check your shocks and 12V battery.

 

Hi NYPrius,

Its not that your traction battery is getting old, just cold. The battery in the Prius is like 30 hp at room temp, and about 10 hp below 10 F.

BTW, this is is a much less noticable issue in the Gen III, as one can keep the engine warm even when running 65 F temp control in 10 F weather. Which benefits in keeping the battery warmer day to day...

 

Wow it must be freezing where you guys are.

:smow:

 

Probably not the issue but......I wonder if the dealer put in the wrong type of transmission fluid. Your car uses WS Fluid. I wonder if they put in G1 fluid by mistake as its thicker..and me be much thicker in very cold temps and could possibly cause the car to feel a little sluggish.

What does the work order say about the trans change?

 

Hi mac...,

Well, its much colder than freezing. I used to walk home in this weather from 3rd to 6 th grade in the UP (upper peninsula of Michigan, where it sticks out into Lake Superior) about 3 miles....If you dress for it, learn how to deal with it, and climb 16 foot high snow drifts (yea, walking along at the second floor level of your neighbor's house), its not a problem....
