Well a electrical gremlin got into my tahoe.. hybrid


it got it started after using the Cruse Control.

the TPMS.. rear right started showing --PSI..
Auto Stop /start issue
then horrible shaking... when in D gear and refused to move
I put it in M4 and was on my way...


gremlin got into my Transmission flushed him out by putting it in MANUmatic 4 mode with Tow mode Off...

the only thing MANUmatic does is shut off the auto start/stop...

Where will he pop up next..

I notice the transmission was a lot smoother when leaving the store and it coasted a lot smoother as well in Drive Gear (before something seemed off and would decelerate faster..)

My theory is putting it in M4 reset the computer (computer issue or glitch)...
Regeneration and Electric motors still work in M mode good information to have

i'll have to go in M4 more often ... to keep the computer glitch from happening


there was also unintended acceleration as well yesterday.... luckily I was not going very fast .. it went from 10 mph to 15mph hour then Auto Stop.. (RPM from 1000 to 1500rpm surge just before auto stop)

also later that evening it refused to move at a stop light (I guess I pressed the gas at the same time it was about to go AUTO stop....) it just sat there Reeving the engine 1500 rpm lol almost got rear ended. because of that...

while it was going into sleep mode I hear of there being surges while waking up from sleep mode but
not going into sleep mode (auto stop)
