What happened 1. A dashboard message has been popping up since December 11 on my 2014 Chevy Cruz car. I only have 77,000 miles on it. The message indicates service tracking control 2. I took the car to the dealer and they said they did a number of repairs and I was charged 900. Some odd dollars to fix some parts to re-Zoll Veve the tracking control issue. 3. I let them know that that message kept coming back up. 4. After several times of taking it back to the dealer paying another $78 for another part they still do not know what the problem is. 5. The main concern is that the message displays over the digital speed control and I cannot determine how fast I am driving. The dealer ds not know how to fix this problem. It is a safety concern because I cannot tell how fast I am driving I have I cannot get this problem fixed, and the dealer ds not know how to resolve the problem.
