Twice now, I've lost power steering for a couple of seconds. I'm driving without TACC or AP and going from one highway to another (Southbay: hwy 17 N, going to 280 N). The car made three short beeps but nothing showed up on the dashboard. No red car on the dashboard like with an automatic warning. The steering wheel was very unresponsive and I had to use a lot of force to make it turn. It felt like the car lost power steering. The really strange thing is that the second time was at the exact same location as the first one! In both cases, it was normal traffic like on any highway interchange. Speed around 40 mph, cars were close, but not that close. Anybody has seen this behavior? Car is a MX 100D, AP2.
