What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2012 Porsche Cayenne S Hybrid, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.
