My C4S Died During Morning Commute

'13 911 4S - stopping and starting
I have had the car for just a few days and today it constantly stopped and restarted when at a very low speed (like going up the driveway) or at an intersection or stoplight. Very unnerving. Wrote my dealer. Keep you posted.

Curiosity...what year and model 991?

Contact Louie in service @ (916) 625-8300. They replaced the Crank Angle Sensor.

If it does resolve the problem I'm good. Cars are so complex these days the odds are that there will be some teething issues. My new 01 Turbo stranded me with 700 miles on it. After it was fixed I then drove it another 11 more years with no probems!

Today it dawned on me. Two times I had starting and stalling issues it happened after I washed my car. Also it happened once in the early morning. I'm thinking it could be a moisture issue. Anyone else experience that? Maybe I should have the dealer wash the car and then try to start it 15 minutes later.

Update: I received my car back today from the dealer. When I went in I suggested to them it might be the crank positioning sensor. I have to admit they listened to my concern about what part was failing. The service provider noted it to the tech. The Tech notified Porsche in Germany and they came back and said change the Crank positioning sensor, add a spacer, and check all of the connections and road test the car. I hope my problems are solved at this point. Keep you guys updated if I get the Gremlins back. So far so good though. It was explained to me that the sensor sits next to the flywheel. The flywheel has teeth on it with magnets. The sensor picks up the signal from the flywheel. They think the sensor is sitting to close to these magnets to pick up the signal properly. This is why they installed a spacer. I recommend to anyone having the same issue to video tape it with a phone if possible. If I didn't they would have turned me away because the problem is intermittent. Save yourself the back and forth headache. Wait for the problem to show itself and film it. Good luck.
I'm happy to hear that the problem with your car seems to be resolved. But it is scary when you think about all the crazy electronics and the critical tolerances.
Enjoy the car in good health!
