2012 Prius V Wagon Issues After Safety Software Update

My 2012 Prius V Wagon has been having issues since the safety software update. I first noticed the car selectively (hit or miss) going in EV mode even after driving over 30 miles on the freeway so its not a matter of the engine and or fluids not heating up. The EV light also rarely lights up while before it was fine. It idles a lot without going in EV mode.

More worrisome is the intermittent acceleration cutting out recently with the warm weather (85F Plus). I have been having scary on and off acceleration issues with the AC on when the car will decide not to accelerate until I turn the AC off even if i floor it. When I turn the AC back on, the car would slow down again. This happens occasionally and usually when the it is quite hot outside.

Anyone else experienced similar issues or can point me to another thread. I love the car and it only has 92K miles on it but the acceleration cutting out is quite scary and a safety issue especially on the freeway. Thanks!

 

It is the most recent hybrid system update that supposedly prevents the Prius from stalling. I will try to find the paperwork and post the number

 

Thanks Bisco!

I have made an appointment with the dealership on Friday. This popped up in my news feed today

Took it to the stealership where it cost nearly $700 to replace the intake manifold, clean the EGR and replace the spark plugs. He said it was all carboned up and was throwing a lot of codes. I thought price was on the high side but I bit the bullet as we are moving and I needed the car fully functional. Isn't there a TSB or some other warranty on these issues. Mine is a 2012 with 92K miles and I bought it used so not even sure if i would be covered.
