I own a 2022 Model 3 with 70,000 miles on the odometer, and it has been well-maintained. When reversing out of the garage, I noticed a rainbow of oily liquid leaking from the middle right of the rear of the car. The leak was worse this morning, but after driving to a few stops, it seems to have stopped. Tonight, I plan to put an oil pan under the car to see if there is any oil and check the color. I am looking for advice on what I should check, as I have already booked an appointment at the service center for next Tuesday. Until then, I'll try to keep driving to a minimum.
