return for warranty,explain this was not a prob until after they woked on it
SUV went to dealer because the cluster screen was not working, dealer said that needed to replace and will cost me $2,000. They also commented that the computer was damage and needed to be replace bur this is cover under the 8 year warranty. Can the damage computer damage the cluster, therefore the cluster should be on warranty as well.
