I have a 1 month old 2023 XC60 T8 phev recharge extended range with 1250 miles on it. I was driving without any issues for the past 1 months. I got a turtle icon with the check engine light on constant when I started driving today. The car had pulled back while driving and there was substantial diminished power, and could be dangerous in the wrong circumstances. I called Volvo and they explained not to drive the car and towed the car to the nearby Volvo dealership. Waiting on diagnosis 2 days now. I've now noticed other vehicles of the same type are having the same issues. This does not seem to be normal for a cars operation to have random diminished power. Website showing this to be a problem with these models from different years without any definitive resolution: https://www.swedespeed.com/threads/2022-xc90-recharge-extended-range-turtle-icon-check-engine-light.657482/

Four times in the last five days as I was braking for a red light or braking as I entered a drive thru, the engine surged and revved to between 3000 RPM and 4000 RPM. I had to use all my power to brake the car and I then put it into Neutral, or shut off the car. Within a few seconds or upon restarting the RPMs were back to normal. I DID NOT push on the accelerator by mistake. The car only has 300 miles so I took it to the dealer. The engine had no codes and they had me drive around with the Service Manager but all was fine. On my way home the same surging, increased engine revs happened again. Luckily I-€™d read a lot about -€œunintended acceleration -€œ so I knew enough to just brake firmly and place the transmission in neutral.
