Greetings members.
2011 V6 Mustang. The following has happened twice in the 4 months I've owned the car (purchased new).
In both cases the car was warm but had been sitting for 30-60 minutes. In both cases I had driven just a few blocks or less. In both cases I had the car pointed straight and true, no loss of traction, rear wheel never broke loose, etc.
So I floor it and the car takes off just like it should, car is accelerating nice, everything is good in the world. Then...all of sudden there is thumping and knocking, I go to the brake and the pedal is pushing back, not acting right, sounds like a tire is off a front wheel, car feels awful! What the hell?? I pull over and check things out, all is normal.
The first time it happened that was the end of the event. I took it in and the dealer found nothing.
Second time was Friday and after pulling over for a look I got back in and took off (not hard, just normal) and whatever was going on, was still going on somewhat. I pull over again, check lug nuts, calipers and even touched the rotor...that was a mistake!! Very hot. Now remember, the car had been sitting for an hour and had been driven about 5 blocks with just the two brief stops I made to inspect the car. Anybody got any ice?
I really think that ABS is engaging on its own, under hard acceleration and for no reason. I'm not a two-foot driver, brake pedal was not being touched. Car was not loosing traction anywhere, for any reason, ever. Just accelerating hard, in a straight line (having a good time!).
I have cornered this car pretty hard, I did have to panic stop once (between the two events, not related to either event), never has this car been anything but pure, she reacts true every time.
I'm thinking the hard acceleration, under the right conditions, is engaging the ABS system (computer is shorting out, vibration maybe, something is sure wrong).
Anybody else had anything like this happen?
Thanks,
