Engine runs rough and activates a flashing engine light. Sounds like the engine is misfiring. On two occasions the engine stalled,(no power steering, brakes...) luckily not in a dangerous situation. No engine codes were visible to a technician when try to diagnose. Car seemed to run fine again after restart.

The SIM has the potential to become disabled and won’t connect to the mobile network. They have announced the problem but it has been months with no remedy even though it’s stated to be performed over the air. If I get into an accident there is a chance emergency responders will show up late if at all. This risk is there everytime I drive my vehicle
