I have a 2017 300S. This morning, I had to boost the battery to get the car started. The first time I tried to start it, the passenger window flew down, and the starter just clicked. It did the same thing on the second try. The car started on the third try, and the Uconnect screen came on, but there was no sound. I drove around town, and got out of the car a couple times. Each time, it started like it should, but still no sound. I went back home for about an hour, and when I left again, the car started great, and the sound was back on the Uconnect system.

Any ideas waht happened with this unit?

 

These cars are sensitive to battery anomalies such as low voltage and arching/sparking. I suspect that in boosting charging the bartt. you caused a small arch that discombobulated the car's electronics. Driving around over time allowed the computer to reassert itself. But do get that batt. situation sorted out as it will cause more problems in future.

 

Thanks for the quick reply. I'll have it checked out, as this is the second time the battery had to be boosted, and the car only has 42,000 miles on it.
