Odd issue

So, I have installed a refurbished battery, inverter cooling pump, cleaned the hybrid battery fan, and changed the oil.

I have no fault codes.

when driving everything is great for about 15 minutes getting to the highway. Once I am on the highway the battery will when it’s above 90 begin to discharge down to 1 bar. The engine will run and the car begins to shudder. I am assuming due to reduced hybrid battery power.
I am at a dead end in regards to what’s wrong.

looking for suggestions. The cabin temp is 72 degrees and I confirmed the hybrid battery fan is running normally.
Ideas?

 

Also new plugs.

 

I will certainly get that app and adapter. It was through a business locally with a 20,000 mile 1 year warranty. They are coming to give it a look. I tested the power to and at the fan. I can hear it if I shut the car off, and then press the run button twice (once I put my ear by it).

I haven’t gotten the triangle of death.

car has 141,000 miles.

 

My OB2 Bluetooth scanner is coming tomorrow and hopefully that gives me a better picture. The shuddering only occurs when the battery gets down to the last bar. I have replaced the spark plugs on all four cylinders and ignition coil on cylinder one. I am going to see what comes up on the next scan with Dr. Prius app. I haven’t driven since the last issue and start it daily to keep battery levels adequate. We shall see what comes up with the

 

I am leaning that way as well. I had a “refurbished battery” installed. I imagine it has been half assed but tomorrow I will know for sure (hopefully). If indeed they screwed me over, I will be filing a dispute with my card provider and ordering a new new battery.

I plan on installing a new timing chain, and all that comes with the kit, I just need to sort this out first.

 

Well the battery drained far enough down that the engine kicked on during the life expectancy test so the results were skewed. So I shall try again tomorrow, but when the engine kicked in it settled at 61.3% which is pretty terrible….
