Model-level reading
What changes the warranty calculation
The Tesla Model Y file contains 6 model years and 3,614 submitted complaints. The middle year in this set has 563 reports, giving each annual count a model-specific reference point.
2023 has the largest complaint count in the current file at 1,095. That does not establish a defect rate because sales volume and vehicle age differ across years.
EV traction battery replacement carries the highest midpoint parts estimate among the applicable repair categories at $13,000. I would check whether that system remains under factory coverage before pricing an extra contract.
