I brought the vehicle in to have recalls addressed on 12/30/24. Starting the next day we noticed the car was weaving without any steering, but thought it might have been icy road conditions and waited to see if it reoccured. The car has since weaved intermittently, but has righted itself after releasing the accelerator. However, on 1/15/25 while traveling about 50mph, the car started weaving on its own and when the accelerator was released the car started to wildly fishtail. Called dealer and they agreed this was a serious issue and agreed to see car the next morning. Service tech said when they drove the car it did the same thing and that the troubleshooting recommended I change the regenerative braking setting to ‘smooth’ and sent me on my way. I did not get even a mile before the car began weaving rapidly again on its own. Went straight back to dealership where manager wanted me to drive the vehicle again with the tech in car which I refused as it is not safe to drive. So he said if I was ok with it tech would take car out again but if it was just acting how regenerative brakes work, there wasn’t much else they could do. When manager returned to talk to me, he said he ended up going with the tech and it did replicate the weaving action two times during that drive. The car is steering on its own weaving wildly left and right and imposes a great danger and no longer feels like a safe vehicle to drive.
