What type of lawyer do I need if a service department refused and neglected to fix my car? It's a safty issue and it's shutting off in traffic.

1.I need a good attorney to help with a service department that refused to fix my car or refer my safety issues elsewhere. They did not work with me to resolve the 3 safty issues. They just dismissed me and told me to come get my car. Not concerned for my safety. 2. Specific Misinformation directly relayed to me resulted in my getting a police report because i followed direct instruction from a higher up.
