Data Attribution & Reporting Methodology: Complaints are unverified voluntary submissions to the NHTSA Office of Defects Investigation (ODI). Because multiple vehicle components can be cited within a single owner complaint submission, component-level rollups may sum to more than the unique complaint count (694). Injury and fatality entries in the detailed table reflect raw values entered by reporting consumers across individual submissions; they are not deduplicated casualty statistics and may include duplicate or unverified entries. Complaint volume is not normalized for sales volume or vehicle mileage and does not represent an audited component failure rate.

Official NHTSA Defect Investigations (1)

1 CLOSED

Formal safety defect inquiries and engineering analyses opened by the NHTSA Office of Defects Investigation (ODI)

Official Federal Inquiries: NHTSA opens a defect investigation when safety screening or consumer defect trends indicate a potential unreasonable safety risk. An open investigation is a formal inquiry and does not by itself confirm a defect or result in a mandatory recall.
CLOSED Defect Petition (DP) ODI Action #DP22005
Opened: 2023-01-27 • Closed: 2023-08-07

Pedestrian alert sounds

Affected Component: ELECTRICAL SYSTEM:PROPULSION SYSTEM

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight ra...
