CX-5 stalled at high speed

The feeling is mutual. Just as I thought...you're no one but a commenter trying to tell others what they can do. Take care!

We're all commenters trying to tell others what they can or can't do, aren't we? You presented a situation and we are telling you what you can or you can't do, but it's up to you to do it, it's not mandatory. Keep in mind that most of us here are just simple Mazda drivers, we're not Mazda gurus. We share from our experience so others, like you and me, and everybody here, can apply and take advantage of what we, as a whole, know or learnt about this car. And save some bucks in the end. Ideally.

One thing you really have to get used to with radar cruise control, is to get into the overtaking lane well before you catch the car ahead.

Otherwise it will just slow down ever so gently to match that car’s speed, and it can catch you out - you look at the speedo and realise that you aren’t going as fast as you had set it. And now you’re stuck behind that car with traffic whizzing past in the passing lane.

You may have seen that you can adjust the following distance - how far behind it will follow.

I wonder whether something weird just happened and (I am assuming) that you accelerated to overtake and maybe at that moment had gotten what it saw as too close, and the car automatically braked at the same time??

Possibly the 2 contradicting events - the car wanting to brake to avoid a collision it had anticipated, and you accelerating firmly simultaneously- cause it to throw a hissy fit??

I would suggest you adjust the following distance to the max and go for another run, bearing in mind that issue of changing lanes well before you catch the vehicle ahead. I am thinking that it is unlikely to replicate the behaviour.

Radar cruise control is a terrific feature. I now have a Mitsubishi 4WD dual cab as well as the (mainly wife’s) CX5 and it just has traditional cruise control, and every time I drive it I curse the fact it doesn’t have radar cruise control. I really miss how good it is.

If you intentionally accelerate, you press the acceleration pedal, you override the brake. The car won't brake, it will let you go.

So you’re saying that when it has activated emergency braking and you then accelerate, it will release the brake???

I dont know if Id be game to test that…..

This is a serious safety concern that deserves their full attention.

That's exactly what I say. The driver has the ultimate authority. You want the car to respond to your command, not to override you. Not just the acceleration pedal but also the brake pedal. The car initiates the braking and let's say you get scared and your first impulse is to press the brake pedal. Your brake input overrides the car's self braking. I hope I explained it right.

I guess you could try it with a big bale of hay in an open field somewhere, I don't know.

In this instance, I don't believe we're talking about the Smart City Brake system.

What else then would make the car suddenly brake?

I went back and saw where he said it started braking. I don't know, but I think two things are getting mixed up: the car braking to match speeds with the car/object ahead, and the emergency (hard) braking from SCBS which is an entirely different thing.
