After 10 minutes running errands in stop and go traffic, I noticed the VSC warning light. It was a hot and humid day (mid-80's). Made it home and was unable to open my garage door with the mirror that is equipped with an automated door opener. I turned the car off so I could open the garage, and when I tried to start my car again using my smart key, it would not start. I put the key in the key slot and was able to start the car, but the smart key, radio, windows and automatic door lock would not work. Mileage is just under 25K. Took the car in to the dealer. They changed an overhead fuse that they said was "blown" and did the 25K service check. The diagnostics showed no error codes. After 2.5 hrs there, they gave me the car...no charge. I drove it about 1.5 miles and stopped for 30 minutes to run an errand. Got back in the car, and again...would not start with the smart key, no radio, would not lock and the VSC was again on. The dealer has had the car all day. They called to ask if I used the bluetooth capability, possibly causing the fuse to blow again. I told them that I have been unable to use it for about one year, and have not used it. They seem to have no clue as to the issue. I need to use this dealership, as I purchased a Toyota Platinum Reward Package, but this is the second time that I have taken the car with a problem unresolved. The service department seemed very busy today which makes me conerned that they are not taking the time necessary to troubleshoot the problem. Any thoughts about what this could be would be great. Not a dumb blond, but could use some advice....thanks!!
