Hi there - am new to this, but wondered if anyone could help. I have a 2009 Chrysler Sebring. We've always had slight issues with the turbo dropping off if you put your foot down, which may or may not be relevant, but on restarting the car it always comes back. Basically we've lived with this as no one has been able to figure out why it happens and no engine management light has come on. Last week, however, my oil light came on. It was only around 6 weeks since the oil had been topped up so this was unusual. I stopped to buy oil and on moving off I braked to allow a pedestrian to cross and the brake pedal was "hard" and the car kept moving. I pulled over, switched off the engine, then the brake pedal felt fine. I drove the car home slowly (only around a mile), but just around the corner from the house it cut out completely. It restarted fine and I drove it down the hill (500 yards). When I came to stopping the brake pedal was hard again. I checked the oil and added more (there was still oil registering, so filled it around three quarters). My other half took the car to the garage last Monday (which cut out around ten times going back up the hill and then drove ok). However, the brake pedal is now going hard and the oil light is coming on intermittently. It only stays on for seconds and when it goes off the brake is normal. The car is still cutting out too. Mechanics are stumped so any help at all would be appreciated.
