The Tesla Model Y has been the subject of contrasting technical and environmental evaluations. A 2026 TÜV report, which analyzed 9.5 million vehicles, identified the Model Y as having the highest failure rate in the 2–3 year age category at 17.3% due to serious or dangerous defects.

Conversely, a Green NCAP assessment highlighted the vehicle’s sustainability performance. The Berlin-manufactured Rear-Wheel Drive model achieved a life-cycle greenhouse gas emission score of 95 g CO2-eq/km, the lowest figure published by the organization to date. This resulted in a maximum five-star sustainability rating and an overall score of 93%, supported by verified manufacturing data regarding the vehicle and its battery.
