NHTSA safety investigation
NHTSA Investigation EA86011
Engineering Analysis · SUN LAND EXPRESS · SUSPENSION
An investigation is not a finding that a defect exists.
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
