3K miles on NAH, bought in May in Oregon.
200 mile highway run to Olympia WA in 90 deg F temp
On return trip the SES light, Hybrid warning light and VDC all come on
Quickly lost speed to < 60 MPH
Surging engine with constant peddle pressure, worse with time.
Pulled off at next exit and drove 2 lanes home.
Couldn't get over 48 MPH
Lost speed on hills
Periodic surging revs without transfer to wheels until > 38 MPH
(i.e. where the electric motor normal kicks off)
Stopped and restarted a couple of times, no improvement.
No regen braking whine.
Lots of surging RPM during some but not all accelerations from stops.
This was a Saturday evening.
Made it home. Let car rest. Started Sunday, rough start.
Local dealer said bring in Tuesday.
Tuesday morning drive to dealer: "Normal" (of course!)
Call from dealer later: codes said water pump on hybrid system to cool batteries (? is this right ?) was shorting out.
Will take at least two days to get parts, should not be driven.
Need to drive to Sacramento next month. Hot hot hot. Not happy.....
BTW: first possible symptoms:
No acknowledgement chime on 'lock' from fob
Trunk did not open from fob, did open from dash
