Brake pressure during startup

Hi guys, I need some advice, I had a minor accident that caused the radiator to slightly bend and needing a new radiator and a front bumper. All were done under an insurance repairer. However since then when i start the car, i have to be really gentle, like very soft on the brake pedal to start. If I press down too further, the car starts however driving down the road for like a 2 minutes I get skid, abs and orange caution light and I loose the regen braking. Car brakes but no regen. I looked at a few threads and replaced the fuse that relates to brakes too no luck. Any ideas? Only way to resolve is stopping the car and turn off and on again. But takes a few tries for it to go away.

 

I got a bluetooth OBD and used Torque app and DrPrius, but neither picks up any error codes when the fault lights are on. I got mechanical insurance so might try a hybrid repairer to see if they come across this and claim under mechanical.
