Intermittent warning "check right tail and brake light" I check and light not functioning; message disappears, lights work and then repeats with light not functioning. Additionally car fails to start on several occasions. Has been in shop 3 days. Not sure if it is wiring harness faulty, circuit board, perhaps harness or sockets burnt, melted.
