Drove brand new 4xe (2000 miles) across many states. Suddenly, upon start on hybrid, the engine is idling at about 1500 rpms and makes a loud noise (almost like a jet about to take off). I ve not been to charge the battery. It stops after 3 minutes or so but it takes pushing pedal to metal to get car moving at speed.. I'm about to drive back home and I'm concerned. Anyone else have this issue?

This bulletin is to communicate that when the combustion engine starts for the first time within a key-cycle (either when the vehicle is first operational at the key crank, or while driving), the propulsion system will generally operate in ‘series-mode’ for up to 60 seconds.
