I've a Tero car. I face two issues 1. Sometimes, it doesn't get switched ON properly. I mean, when we connect the car motor cable to battery cable, we are supposed to hear two beeps. Sometimes we hear only one. That time, it doesn't respond to remote. Sometimes randomly it works. 2. Braking when it goes forward doesn't work effectively. When the break is applied, it stops after few seconds. However when it goes reverse direction, the braking works perfectly and responds to remote properly. Please help.
