So as we all sit here patiently waiting for our glorious 4xe's to start shipping, I'm wondering if there needs to be any modifications to the suggested break-in procedure? I looked through the 4xe supplement and there is nothing mentioned that I saw. So then I reverted to the 2021 JLU owners manual; see below in red for excerpt.
Seems that will cover the ICE and rest of the mechanical powertrain but should we be doing anything specific for the high voltage system?
ENGINE BREAK-IN RECOMMENDATIONS — GASOLINE ENGINE (IF EQUIPPED)
A long break-in period is not required for the engine and drivetrain (transmission and axle) in your vehicle. Drive moderately during the first 300 miles (500 km). After the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the limits of local traffic laws contributes to a good break-in. Wide-open throttle acceleration in low gear can be detrimental and should be avoided.
