While driving 10 to 20 mph power steering fails followed by all electronics flashing and then by car engine dying. Control of car is very difficult and dangerous. Power steering has failed about 20 times engine failure about 10 times. Dealer told me they found hits on the onboard computer, were able to repeat the problem and eventually tracked it down to the power steering. But have failed to find a problem. They now deny all of this. I question if the car is safe.
