Hello,
This sounds like an issue with the vehicle stability control.
It could be the module or number of other issues triggering the error light.
First you will need to get the ABS module scanned for trouble codes. It can help determine the issue. As this could as simple as a sensor at the wheel which might have gotten loose or a wiring issue.
Here is a helpful video of how to retrieve those codes:

The engine light can be related to the same issue.
