Owner complaint summary

Driving home from work and I seen the "service brake assist" light popped on. I did not know what that meant, until I tried to slow down around a curve. The brake pedal was extremely firm and mad stopping in time almost impossible. I made it home and looked on internet for answers. I checked the sensors, brake fluid and checked again and no help. I noticed a puddle of oil under the car and checked the lipstick which showed i was very low on oil. The next day I had to tow the car 45 to 50 miles to dealership. The dealership had car for 3 days and told us it was the brake vacuum pump that failed. The vehicle was not under warranty and we paid over $800 to have it repaired. We live off a busy road and it was very hazardous driving it home.
