Bought it yesterday and was stranded after only 60 miles. The rear brake started to drag and was billowing smoke and the rotor was glowing red. It was dragged back to the closest dealer and today they tell me there is no problem. Has anyone else had this issue? could the hill assist be locking up? And no the E-Brake was not on and I didnt feel anything apparently wrong with the brakes but of course I didnt know any different as the car has 60 miles on it. Thanks for any help and replies. Here is a picture of the rotor after it had cooled down a little bit already.

Any chance it was wet and then cold enough for water to freeze? I ask this because Mk2 MR2s would get moisture in the ebrake lines. It would then get cold and they would freeze engaged. You could get new lines or not park with the ebrake on. Otherwise like you suggest something like hill assist stuck on.

I live in cal and when I got this car yesterday it was in the mid 70's . Apparently they dealer took "everything apart" and could not find a problem when there clearly is one lol. Thanks for the suggestion thought.

amazing how you can buy a new car, have photo evidence and then they say, "nothing wrong with the car."

Would have been nice if they replaced the rear caliper and the bits as a precaution and to show good service.

We'll see if it comes back!

Gaah, my mr2 did that. What a pain!

Sucks that this is happening with such a new car, but I'm sure that was an anomaly. Maybe the dealership solved the problem just by disassembly/ reassembly for inspection. Good luck and welcome!

They couldn't find anything mechanically wrong, meaning is was most likely a software glitch, having to do either with the anti-lock programming, or the torque vector programming. .. since you could drive the car and the wheel hadn't locked up also makes me thing the programming or black box is the culprit.

wow it looks like the parking brake was engaged and/or dragging.

 

[Mark629]

The parking brake may be the problem but i definitely didnt have the handle up on the brake while i was driving. The first dealer couldnt find anything wrong but the dealer i bought it from wanted to take a look at it so still it sits down at the shop waiting to hear back as to what they find.

Dumb question but did they take it for a drive?

 

[BlackBird]

That is very strange.

Just throwing ideas until one sticks here but... I've had an old Mazda 6 (first gen built @ Flat Rock) go nuts when the ABS sensor was dirty. The entire dash and everything electrical just either didn't work or was partying like it was Christmas. Maybe it is a faulty sensor of some sort and not the brakes.
