No, she is clueless about stuff like that. How did you find out about the update? I wish they would publish all the latest updates on a web site so you could know about them. My next scheduled maintenance is in about three months, so I will ask about it then.

In my case I always start with keyless. When it does not start, the key does not help also. You have to somehow trick the car by arm/disarm or open/close door. It is definitely a glitch. My bro also bought a C300 ( the day after I bought my) but his car has a much later build date and never encounter this issue. I wonder how many of us have this issue - car does not start - the rpm needle rotates and then goes back down, no sound at all. Main indicators - brake feel heavy when you depress it to push start, both 'park', and 'brake' light is lit.

I had the car in for service and mentioned the problems I had with Keyless Go. They checked for updates, told me there was now one available for that system, and installed it. I have had no further issues with it since then.
