NHTSA Escalates Probe into 135,000 Ford Vehicles Over Engine Failure Risk

The National Highway Traffic Safety Administration (NHTSA) on Monday said some older Ford cars and SUVs pose an unreasonable safety risk due to a potential timing belt failure that could cause the vehicles to lose power while in motion.

Investigation Details

The U.S. auto safety regulator has upgraded a defect investigation into 135,551 Ford vehicles equipped with 1.0L engines. The probe now covers various model years between 2014 and 2021.

The specific models under review are:

• Ford Fiesta
• Ford Focus
• Ford EcoSport

Upgrading an investigation is a formal step indicating that the agency has found sufficient evidence to warrant a more in-depth engineering analysis, moving it closer to a potential recall demand.

The Reported Defect

Ad

According to NHTSA, the core issue is the potential failure of the engine's timing belt. The agency stated it has received reports of 355 incidents where drivers experienced a low engine oil pressure warning light immediately before a complete or significant loss of motive power.

A sudden loss of power while driving can increase the risk of a crash, particularly at high speeds. This development prompted the agency to escalate its review to determine the scope and severity of the potential defect.

Context and Implications

This upgraded investigation follows a preliminary evaluation to assess consumer complaints. If the agency's engineering analysis confirms that an unreasonable safety risk exists, it can formally request that Ford issue a recall to repair the affected vehicles.

For Ford, a potential recall of this size could result in significant costs for parts and labor, as well as potential reputational impact. The outcome of the NHTSA investigation will be closely watched by owners of the affected models and investors.
