Per Rusnak and Fletcher Jones, they do see many issues with Hybrid sessions for all hybrid even though not many Hybrid in CA due to Tesla. Now I understand the price is dropped so steep for Porsche Hybrid. Porsche Atlanta took good care of the last fix. I am convinced I don't get a lemon. I see I have a problem around 36K miles with different sensors related to Hybrid. My 2 other Porsche ICE are rock solid and very happy.

I will update what Fletcher Jones finds out.

 

$2600, Porsche NA paid half as goodwill. Z Vale chiller valve. remove front bumper, drain coolant and retrieve freon. BTW, while they are doing that, I asked for air filter replacement for $100. Surprisingly, I did not see the part #.
Porsche took the car in as Trade-in for low price $30K, but the fair market for 2016 pan HSE with PP+ and PDLS+ @42Kmiles is $45K retail. I guess I will the car for a while.
