Tesla Model Y 2021

🚨 What to check before buying

Overall risk score: 10/10

Serious risks

• Battery degradation: Gradual capacity loss, typically 5-10% over 150k km. Faster if frequent Supercharging or extreme temperatures.
• Suspension control arm bushings: Upper and lower control arm bushings wear, causing clunking noises. Common in Model 3/Y.
• Drive unit whine/bearing noise: Rear drive unit can develop bearing whine. Usually covered under warranty but expensive out-of-warranty.
• Heat pump failure (2021+): Heat pump system in cold climates can fail, reducing heating and range. Octovalve is the common failure point.
• 12V battery failure: Auxiliary 12V battery can die, making the car completely inoperable. Replacement is straightforward.

Additional notes

• Tesla Model 3/Y front lower control arm ball joints wear prematurely, especially on Bulgarian roads. MCU screen can yellow. Parts availability improving but still limited. Budget €500-1,500 for suspension work.
• Electric vehicles with 100k+ km may have noticeable battery degradation (10-20% capacity loss typical). Check State of Health (SoH) via OBD reader. Battery replacement costs €5,000-15,000 depending on vehicle. Factor this into purchase price.
• Electric vehicle with 100k+ km: battery degradation becomes a real factor. ALWAYS request a battery health report (State of Health / SoH). A 10-15% capacity loss is normal at this mileage. More than 20% loss is concerning and will significantly reduce range and resale value. Battery replacement costs €5,000-20,000 depending on the car.
• Electric vehicles with 100k+ km may have noticeable battery degradation (10-20% capacity loss typical). Check State of Health (SoH) via OBD reader. Battery replacement costs €5,000-15,000 depending on vehicle. Factor this into purchase price.
