Electric vehicle maker Tesla has placed last in a US-based study that surveys problems reported by buyers of new-cars within the first 90 days of ownership.
Conducted by J.D Power, the Initial Quality Study (IQS) uses a metric of ‘problems per 100 vehicles’ (PP100), ranking overall brand quality with a numeric score – the lower, the better.
Tesla placed last in this year’s IQS with a score of 250. This means, on average, 250 problems were reported for every 100 new Teslas – or 2.5 problems each car – within the first 90 days of ownership.
This year was the first Tesla was involved in the study, despite not being “officially ranked” among other brands for not giving permission to have its cars surveyed in 15 mandated states.
However, a J.D. Power spokesperson said the brand could be included in the survey because “[J.D. Power] (was) able to collect a large enough sample of surveys from owners in the other 35 states and, from that base, we calculated Tesla’s score.”
