I have a 2020 Outlander PHEV. It was purchased in December and only has 1,600 miles on it. Was driving on the freeway last week, going 70/mph - out of nowhere lights start flashing “EV system service required, stop safely” and “RBS service required". It was terrifying as the car slowed to about 20/mph while on the freeway, and I had to quickly pull to the side of the road. I shut the car down, waited a few minutes and restarted it. It started fine, but the "service engine soon" light remained on. I was able to drive it the 25 miles to the dealership, and a few times during the drive the FCM system randomly was activated flashing "BRAKE". Really scary experience all around.
After sitting at the dealership for 5 days I was told they reset the computer because the 12v battery was low. When I inquired how it could be low on a brand new car, the tech said going forward I needed to start the car everyday and drive it around, and the battery was low because I must have let the car sit for a couple of days. How unreasonable is that?? Guess I can never go out of town or expect a dead 12v battery?
Looking back on it, in the days leading up to the incident, the FCM randomly kicked in a couple of times, but I assumed I was just too close to another car.
Anyone else have this happen? I'm kind of afraid to drive the car since it sounds like it's only a matter of time before it happens again. I owned a plug-in Prius hybrid for years and never had to drive it daily to keep the battery charged.
