Yesterday, on the way back from a 4:00 AM airport run, stopped at a DCFC for a 10 min pit stop, as I have many times before.
Charged to 80%, tapped ChargePoint ID card to stop the session.
Powered up the car, put it in D and NO GO PEDAL response.
Powered down and back up and noticed a brief "Initializing...Wait to Shift
" pop up on the blue screen before the normal screen.
It had the 'Check Engine' light lit on the left border. Tried several power cycles. No Joy.
Went into the grocery store where the DCFC unit is located and bought the only tool they sold, needle nose pliers and disconnected the Negative 12V battery lead for a minute, reconnected, No Joy.
Called OnStar and got them to read the code, and they emailed it to me:
The code(s) and explanation(s) associated with this issue is/are:
P1FF4 The Lithium-Ion Battery is not performing as expected. An issue has been detected in the Onboard Charging System which manages your vehicle's battery pack charge level.
Had it towed 32 miles to my local Chevy dealership on OnStar's dime!
(I have AAA, but 2 months ago I contacted OnStar because myChevrolet app was not working correctly, uninstalled app, reinstalled and all was well, but the OnStar tech support guy gave me a 3 month trial of the full feature service which includes roadside assistance!
Waited for the dealership to open and was given a 'Free 2 day loaner', an '18 Cruze Hatchback with the RS package !
They couldn't shuttle me 2 miles home that morning so I took the loaner. Need to drop it off at 7AM when they open on Monday morning and then I'll get the shuttle ride back home to drive my smelly gasser until the 'Volt Tech' guy can look at my Spark EV during the weekdays.
(Hopefully they are better at this than when they had to trouble shoot my '13 Volt....)
So,, place yo bets on how long the car will be down
and what went bad
1.Main contactor fizzled out with the constant 48 kW charging. (but then I flog it all the time at way more power. Only that's going out, not coming in.)
2. One, or more, cells gave up the ghost during the DCFC session... (my favorite! Come on whole new fresh battery pack!!!
I'll have the 'Range Estimation' Recall performed at this time.
The service tech gal signing me in gave me the side eye when I told her I knew about the recall but elected not to have it performed because my range estimation was working properly. She, "Blah, blah, the Interconnectedness of All Things..." Me, "OK, see you Monday."
So, Spark EV's can let you down.
Used '14 2LT w/ DCFC.
+67 K miles. Mostly free electrons! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
