If you had hit the obstacles on the side then I would agree on blaming the PA, that would mean it failed to calculate the spot and distance to curb etc.. But youīre saying you hit them with your rear end, so the question is did you fail to stop as it would/should have indicated for you to do that on the screen? Didnīt the sensors warn you? If not, then you should have no problem getting it fixed on warranty. I guess they should be able to find some kind of error code for it.
I added PA for the exact same reason - my better half. The times Iīve tested it itīs been flawless *knock on wood*
