My car has randomly shut off 2 times in the last 48-72 hours. The first time in happened was a stop light, while idling the vehicle shutoff and restarted. The second time it happened was while actively driving the vehicle approximately 30 MPH. The vehicle has been taken to a local dealership and they are unable to figure out why this is happening. there is no check engine light or any other warning lights present both times this has happened. This is a huge risk for this to happen while the car is actually in motion.

Trouble code:P0011 Mechanic replaced timing soliend. On driving car home, the engine began shutting down. Took back to mechanic who stated he could not get the engine to repeat trouble. Continue to drive and see what happens. Continued to drive but engine shut down got continuously worse and there is a sound like a fan blade is knocking against something (best way I can describe the noise)which is intermittent. Headlights are very dim. This was noticed late last year. It got so bad that I started to Google it and found there are other companies about this online including that the high beams don't work at all.
