Interesting. The few times I've had my car in for servicing, I've either gotten updates from the service advisor either by email or by phone. Personally I prefer these methods to a text, because more information can be conveyed (one of my service advisors wrote me a highly detailed, multi-paragraph email about some warranty concerns I had). Also I'm too cheap to have a texting plan for my cell, thus every text costs me like 10 cents.
