Hyundai 757-9 2013 Drives fine and goes through gears fine but sometimes when you stop it jumps to neutral and won't select forward or reverse. Have to switch engine off then back on and it works again until it does it again. Possible TCU fault? Any help greatly appreciated. London based
Just a guess . Maybe the neutralizer switch when you apply the brakes is sticking? I don't anything about the way that system works on this machine.
try pulling back on brake pedal
Where is the neutraliser switch located?
