This suggests that the car has gone into a fail safe mode. This is a safety mode that the car will go into when the computer has detected that a critical component has failed or is not working properly. This is a preventative measure activated by the car’s computer to keep the driver safe and/or to prevent further damage to the parts that have failed.

I would recommend having a certified mechanic, such as one from YourMechanic, look for a Check Engine Light and download any trouble codes.
