What we fix

Find the problem that sounds like yours, or book a diagnostic and we will track it down. Prices are estimated starting points; your written quote comes after diagnosis. Some faults can be diagnosed remotely, so you may not need to bring the car in first. We serve Tesla owners across the Charlotte area from our shop in Harrisburg.
