Why Tesla Model 3 Owners See This Pricing

Many traditional repairs do not apply (no oil changes, no spark plugs). When repairs are needed, Tesla-specific parts and limited shop availability raise prices.

For reference, the national average for serpentine belt replacement on a typical passenger vehicle is $100 to $250. The Tesla Model 3 runs about +25% versus that baseline.
