Wow! Same issue I had. Exact same and same company. Ok. So in my case I listened to all advice above but I sent it back to RC Geeks. They will get back to you but they are unbelievably slow. They won’t talk to you on phone Whatsap FaceTime they just want to email. They were really helpful tho I have to say. I assumed they were blanking me but I think they are just small. So don’t panic too much about that like
I did.
We went through a few checks. Ensuring you switch the car on and then the controller not the reverse as I did in the video. But I am 99% sure I tried it the way they recommended to. They recommended I post the car to them. They took it out the box and it worked as normal. So that was annoying. But I just wanted a working car so was happy. When they sent it back it worked absolutely fine. No issues. Until last week. Now it only goes in reverse.

I thought maybe if I just let it sit round and recharge the battery it might work. Tried it today no change. Just had a thought. The only other thing I did when I sent the car back to geeks is remove the batteries from the controller. Maybe that makes no difference I don’t know maybe just worth trying.
