Last week I had multiple warning lights all come on at once. Hill Assist, Service Traction Control, ABS, Air Bag. Along with that the Screen displayed my back up camera while driving forward at any speed. Brought it to the dealer and left it for two days. The repair was a corroded connector in the White Wire at the Left Front ABS Sensor. This connector is protected with a rubber boot, but it wasn't "sealed with sealer". I asked if just mine wasn't sealed with sealer or were all cars not sealed with sealer. I was told "no cars are sealed with sealer, there is just the rubber boot covering the connector. The repair was to clean the connector from corrosion and splice repair the wire and shrink tube the repair and reattach the rubber boot and glue/seal it in place. No charge of coarse and a free rental car. I just thought I'd post this in case anyone else gets a warning light party display.
