Subject: Urgent Safety Concern â Immediate Attention Required Dear To Whom it may Concern, I am writing to urgently express serious safety concerns with the vehicle I recently [purchased/test drove/had serviced].

Independent shop says there is a potential design defect with the Tesla motor used in this vehicle (many early model S motors were replaced by tesla.)
