What may be wrong with it? The anti lock and the trac off light also comes on when service traction system light comes on. How long will l be able to drive with the car being like that?

It sounds like ur ABS sensor is either loose or the wire is frayed. Even though it happens when u turn left it still could be either side that is at fault. The front wheels need to come off & the ABS sensors/wires/connections need to be inspected. Upon inspection u should find an obvious problem there. The sensors r located on the behind the wheels close to the outside axleshaft. Then simply tighten it back up or replace the sensor/wire if its damaged. (kinda expensive new- u should be able to find a used one)

BTW the Traction Control & ABS systems r intertwined so its normal that they both come on.

You can drive the car as is but keep in mind that while the light is on or if it stays on ur braking ABS will be greatly impaired. (even so- without ABS ur car will still brake normally)
