I had similar about a month or so ago, new Mps4 on the rear, half worn Mps4 still on the front.
It took a good few hundred miles for it to feel comfortable, dsc was flashing regularly and was real pain when it kills the power just as you're part way through booting it.
It settled down every eventually and I did an alignment which helped it get back to normal
