Help! I have a 2014 Maibu. I have only had it 6 months. 7 days a go the engine light came on wgile i was out of town. Once i got back home the engine light was off. I have taken it several places to see why the light is on. The only code that comes up is the brake power booster. Now the car is loosing power,the reduce power light is coming on,engine and it is cutting completely off. It will start back up.Has anyone else had this problem?
