Thank you, NemesisUK. Will make sure I mention it to Lexus when they take it in to replace the bumper.

Thanks, rayaans

Good points, it would not have come back on. What I remember happened is all kinds of dash lights flashed (indicators, etc) and then it showed the loading screen like it does when I press the start button to start the car (not just the noise when the engine stops and starts). But I am probably imagining it. 

Thanks for your input again.

Hi guys, 

I love my new NX300h (67 reg). Unfortunately, someone rear-ended me yesterday when I was stationary in a traffic jam. Damaged plastic bumper, waiting for insurance to sort out. Hope that they won't find hidden faults when they start repairing. Anyway, I can swear that the engine "stalled" and restarted immediately when I was hit but I was in such a shock that I could have imagined it. Could anyone shed some light on any automatic shut off systems there are in the model? Just curious to figure out whether the stalling sound and jerking forward was purely down to the impact, or something else happened.

Needless to say I googled it already but nothing significant came up. 

Thanks in advance
