PLEASE HELP!

Hi all. I just recently purchased a 2016 Prius Four Touring. Initially, I loved it!!! I was making insane gas mileage & the vehicle had incredible power.

Then, one day I heard (& felt) a popping sound from under my feet. Suddenly, I wasn't making the same mileage anymore. More like 10-20 mpgs less.

Also, weird stuff is happening. First, I noticed the gas engine keeps turning on to charge the hybrid battery. I can have 5-6 bars showing on the hybrid eco monitor display, and the gas engine still comes on to charge the hybrid battery...even while breaking.

Second, I noticed that the hybrid battery doesn't seem to be holding its charge overnight. The bars on the battery monitor start dropping as a pull out of my driveway, and then the gas engine starts charging again. This has become very frustrating as I keep starting mpgs at a deficit. I will literally go from the display showing that I am making 60-80 mpgs to dropping down to 18-22 mpgs (sometimes into the single digits) because the gas engine was staying on to charge the hybrid battery. It takes about a 20+ mile trip before I start getting into the listed mpgs. It's driving me crazy!!

Also, I notice that my car feels like it's lost some power too...just not the same pickup. Finally, I'm noticing an intermittent howling sound when accelerating.

I have gone back to the dealership to resolve these issues. The Prius certified mechanic hooked up the diagnostic computer to my car, and said he couldn't find any problem. He recommended that I come back when my first service is due to have it checked further. I am now getting due for service, but I have some confidence issues going back to that same dealership.

1. Does anyone have any idea what might be the problem(s)??

2. Can anyone recommend a prius mechanic at a dealership that could diagnose what's wrong with my car??? I live in southeast Florida...Ft. Lauderdale area.

THANK YOU!!!

 

Purchased in August.

Temp been pretty consistent in the 80s.

Popping sound heard while slowly pulling out of garage. Never heard again.

Almost always in Normal mode.

 

Thanks! Just hoping for a referral from someone who has been really happy and confident in their mechanic.

 

I agree with you...it's pretty scary!
I did call Toyota and have a case#. I appreciate all your suggestions!!

 

Thank you! Great idea!

 

Will do, thanks!
