Attn: Tesla Roadster Owners News story: http://www.pluginamerica.org/drivers-seat/plug-america-research-launches-sec... This week, Plug In America launched a survey of Tesla Roadster owners. Although absent reports of issues with battery capacity loss, the Tesla Roadster user base has significant experience with electric vehicles that have been on the road since as far back as 2008. With the Roadster survey, Plug In America plans to explore several topics: How does the Roadster battery pack hold up over time and miles? How does this compare to owner expectations as set by Tesla Motors? How well does the Roadster's active thermal management protect the battery pack against hot and cold weather? How do version 1.5, 2.0 and 2.5 Roadsters compare in battery longevity and major maintenance? Is there a difference in drivetrain maintenance between the Roadster and Roadster Sport? How common are major Roadster drivetrain component replacements? What should owners know when considering purchasing an extended warranty?
