CLS 350 - Did we buy a bad car?

We just took delivery of a 2006 CLS 350. On the test drive, there were no issues. After registering the car, my brother drove it to a car wash to give it a good clean. We splashed out on a steam clean and under-carriage wash. There were no issues then. After the wash, we noticed error messages on the dash.. ESP, ABS and Speedtronic error. Also another issue was stating that the "Runflat indicator not detected".

Is there anything wrong with the car?
