ABS issues Cooler weather?

[LeftCoastOverland]

So the last few mornings I’ve been experiencing ABS / Traction control / hill assist warnings on my dash.

First start of the day, 13 Deg. C. Drove it a bit down the way could hear the tires screech on some right hand turns… so something is up.

After it warms up / second start of the day no more issues.

Bleed the brake system?

It's definitely your choice of music. Change that and it will go back to normal

- Is your pedal height and feel the same with hot and cold brakes?
- Can you feel the pedal pulsing when it happens? ABS activation gives a characteristic pedal pulse of several cycles per second.
- Is it only when cold and only for right turns?

Try riding the brake pedal for maybe 10 seconds when you first move off with cold brakes. If getting heat into the brakes and hubs early makes it go away I would suspect something mechanical around a wheel speed sensor, tone ring or a caliper. Perhaps a tired wheel bearing is letting a hub move around enough when it's cold to screw up the wheel speed sensor air gap.

There has been a few reports, me included, where there was a weird ESC intervention if you brake hard while turning. The pedal height drops and you feel a momentary ABS intervention. Is this different?

Regardless, don't mess about with it for too long if your dealer is accessible.

Sounds more like the rear differential failures a couple of owners have had, I would be carefully noting every occurrence and contacting your dealer.

Actually that’s a good point. I’ve assumed @LeftCoastOverland was talking about the front wheels but he doesn’t actually say front or rear. And those dash light warnings weren’t mentioned in the locker failure posts but the general symptoms are there.
