We picked up our XC90 Recharge ER on Saturday. It's a fully loaded Inscription and an incredible upgrade over the '18 Momentum that we traded in. One oddity I've noticed, however, is that twice now I've had the engine turn while not moving, despite plenty of EV range left. Both times were shortly after start up (still parked) - once in my garage and once in a parking spot. I don't think I did anything at all to prompt it. Once the gas is running I'm unable to select Pure mode without turning the car off and back on again (see attached).

Anyone else seeing this behavior? Is it something I'm doing? I understand the gas engine may run once in a while to burn off stale gas, but this happened on days 2 and 3. On day 1 we drove 150 miles, so it shouldn't need to burn anything off...

I just ran across this thread which contains some similar-sounding experiences. I'll continue to monitor it, but given that the car was just built I don't have a ton of hope that a software update fixes it. XC90 T8 runs engine too much.

I've not seen this issue over the 2000 miles I've had my 2022.5 ER R Design. I have driven 20 to 30 miles a day the last two weeks and the ice hasn't kicked on once.

Not to say I don't have issues. My steering wheel sounds like I have a bad bearing in the column. I get a clicking noise at low/no speed turns. Also, my car seems to charge for eternity. I had it plugged in one day for 24 hours on 110w and it still acted like it was charging. Green light flashing on port and time on car dash and app just kept extending.

Hopefully the software stuff can be corrected with an update.

I recall seeing mention on an older thread (at least a year or two ago) of this issue and it may have been a SW related issue. I don't remember for sure but I don't think it was HW.

I noticed this a few times. It appears that if one puts the car into gear immediately after turning the knob to start the car, the car would start the motor while going through the check list on the dash. It's possibly a feature to provide power right away when electrical system is still being checked.

If I allow the check list to complete before putting the car in gear, the gas motor stays off until the appropriate drive mode is selected. Not sure if this is what the OP is seeing. Sounds close.

Do you not have a “Hold” option? Something that makes the car behave more like a conventional hybrid, saving most charge for later use?

Hold
Battery level sustained for later use.
The function maintains the charge in the hybrid battery for electric drive and saves available electricity for later use e.g. for driving in an urban environment.

Yep, and/or switching from R-N-D or D-N-R too quickly will cause the ICE to fire up for some reason.

Immediately switching into gear sounds very plausible. I'll try to recreate that today and start letting it get through initialization first. Thanks for the responses.

Yeah, I suspect that is it, it is only a difference of only 1 Mississippi's needed ;)

Well that wasn't it. Had another engine start today while resting my foot on the brake waiting for the startup sequence to finish.

Question - when the engine starts for a "maintenance cycle", is there any indication of that being the reason?

Time to start recording every start on video I guess. I'm also going to sit in the car and cycle on/off repeatedly to see if it happens that way. I had four starts today (all 2-3 mile drives) and a full battery.

It seems your engine started before you even touch the gear selector.
If it keeps happens before you select a gear, it may be time to get in touch a dealer. We've had our car for about 2 month now. Many short trips on electric only, and the gas motor stays off except the couple of times I was too quick to put it in gear.

Yeah, that is different than anything I have seen. Always starts for me when I do something quickly, like D to R, or D to hitting the gas, something like that where the car might be intentionally programmed to anticipate request for more power. Then if it is the 1st start, it will run for about a minute then revert to normal on demand mode.

To follow up on this, it turned out to be caused by a Progressive Snapshot device plugged into the OBD II port. I haven't had a single hiccup in the last 2000 miles since unplugging it.

That device was probably rapidly draining the 12V battery. It should be reported to their technical department, a serious design flaw.

If interested, the SOC of the 12v battery and parasitic/standby drain can be read in Car Scanner Elm Obd2 app (with generic obd2 dongle). This app will also show the state of charge and temperature of the high-voltage battery pack.
