Car drops into HV mode randomly & engine racing
I drive around town daily and rarely go enough miles to drop into HV mode, as the ~47 mile EV range is 95% sufficient for me. I keep the car in EV Econ mode and I find that the car will occasionally shift into HV mode at low speeds at a near-full charge on flat residential streets. After a few minutes, it will usually move back into EV mode, but this is frustrating as I really don't want to be in HV mode while I have a charge.
A secondary issue is that while in HV mode, the engine speed doesn't necessarily have anything to do with your current speed, acceleration or grade. I've had multiple instance where I'm at a steady slow speed (e.g. 20-25 MPG), or coasting on the freeway (65-70 MPH), or decelerating using regenerative braking, where the engine is revving at a very high speed. In a couple of those cases, the revving was high-enough to vibrate the interior panels and make the car sound like a 1976 Honda Civic 1600cc. Not good.
I'm wondering if anyone else has run into this issue. From a software standpoint, this vehicle has been updated with the patches in SB 18-069 and SB 18-079.
Please advise if you have experienced this and/or if you know of a solution.
