I don't think it's a faulty sensor, maybe they are oversensative
That’s what I was thinking too. It only happened the once when in traffic
I’ve just been in contact with the dealer to clarify a couple of details like the Honda warranty period & Honda Assistance (AA) etc
I’ve also asked if it’s ok to look underneath the car up on a ramp before handover, it’s just something I like to do when buying a car; it ensures there’s no oil leaks and double checks exhaust condition etc. The dealer had no issues with that
I’m probably being over cautious as the car is only 15 months old but I like to be careful with these things
