“Pedestrian alert sounds 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 rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.”

What would change this answer

verified remedy

A newly verified completed remedy with configuration-specific eligibility for Manufacturer service campaign, Pedestrian Alert Sounds investigation could improve the recommendation.

Source notes

contradictory source

A reviewed official or independent source that materially contradicts the claims for Manufacturer service campaign, Pedestrian Alert Sounds investigation would force confidence and verdict review.

Source notes

changed applicability

Reviewed evidence that includes or excludes a different year, engine, drivetrain, trim, or VIN population would change which issues apply.

Source notes

lost exposure eligibility

A verified production denominator and eligible time-at-risk cohort are required before normalized comparative year guidance can strengthen.

Source notes

Applied assumptions

  • · 12,000 annual miles
  • · 3-year ownership horizon
  • · Service history is unknown unless verified by the buyer.

Sharpen it further

  • Add mileage so we can compare it with mileage in owner reports.
  • Add the miles you drive each year. We currently use 12,000 miles.
  • Choose how long you may keep the car. We currently use 3 years.

What this check cannot seeYou still need to check the service history, title, accident history, repairs, and the car’s condition.
  • ConfigurationAvailable

    The engine and drivetrain were matched for this check.

    What to do: Make sure these details match the car before you rely on the check.

  • VIN recall & historyNot verified

    This page cannot confirm open recalls, title records, or odometer history for one VIN.

    What to do: Check the VIN with NHTSA and get a title and history report.

  • Repair costNot verified

    We do not have a sourced repair cost for the listed problems.

    What to do: Get a written repair estimate for the named issue from an independent shop before you negotiate.

  • Market priceNot verified

    TireKick does not have current market prices, so we cannot say if the asking price is fair.

    What to do: Compare the asking price against recent local listings for the same year and configuration.

  • Mileage in reportsAvailable

    Enough reviewed reports include mileage to show a range.

    What to do: Treat the mileage as a range in owner reports, not a prediction. Confirm the car’s condition with an inspection.
