Engine shuts down

Post by vitoman58 » Thu May 06, 2021 2:58 pm

Over the past three weeks I 've had the engine turn off twice whilst sitting in traffic.

When I'm waiting at lights or in heavy traffic, I almost always put the selector into Neutral and engage handbrake. On both occasions this was the situation. The first time, whilst waiting I undid my seatbelt to remove my coat - did that and traffic started moving. Put the selector into Drive but nothing and then the selector sank into console. Had to restart engine.

Yesterday, was second incident. This time all I did was ensure USB cable for phone was connected in central cubby hole. Nothing else. I noticed the light around the start/stop button was flashing and again the selector disappeared!

I can understand the first time (I think). I'm assuming the car will turn engine off as it's unsafe to drive with seatbelt unbuckled. But can't work out yesterday.

Any ideas anyone please?

It sound suspiciously like the start stop kicking in. Perhaps opening the door or unclipping the seat let shuts the car down.
I'm not sure fully how the s/s works as mine rarely does :lol:

Most times when i reverse into my drive put the selector in park and take off my seatbelt my engine turns off automatically too, mine is a 21 model though and always thought it a feature

The engine shutting down is part of the "Driver exit" feature when stop start is enabled.

I think Phil is spot on with the probable cause of your engine shutdown.

Having said that, once I set off on a journey, my gear selector does not move from the D or S position until the journey is finished!

I read this in a Topix brochure.

When the vehicle is stationary for a short
period of time (e.g. in stop-start traffic), the
selector may be left in D or S. When stopping
for extended periods, either select P or apply
the parking brake and select N.

Not sure if traffic lights would be classed as an extended period. Obviously if traffic was at a complete standstill I would then select neutral and put the park brake on! :D

Thanks all. I'm just hoping it's me being stupid. As I said, I could understand the first time when nI unbuckled seatbelt. But I'm pretty certain the second time it was in neutral and handbrake on and that was it.

If it doesn't happen again it's definitely user error :roll: !

I think anything over 3 minutes would warrant selecting neutral
