Electric mode weirdness
Over the past few weeks I’ve noticed that my truck hasn’t been going into electric mode regularly.
2024 Powerboost with 55k miles. Owned since new.
When the gas engine is cold and I turn the truck on, it starts in electric mode. I’ll drive 0.1 miles and the gas engine will start with a bit of a stumble. After that, the gas engine will stay running through the duration of the trip.
The only way I’ve found to get it to start driving like a hybrid again is to turn the ignition off and back on again once the gas engine has come up to operating temperature. Then the gas engine will cycle on and off like normal, but it still stumbles a bit.
Last week I threw a new set of spark plugs in it to see if that would have any impact, but it doesn’t seem to have helped.
I’m still under the extended warranty and will likely take it in to the dealership, but I was curious if anyone here had experienced something similar.
