Customers Complain That EcoBoost V-6 Stalls
The National Highway Traffic Safety Administration is examining reports that some 400,000 Ford F150s equipped with the twin-turbocharged EcoBoost V-6 engine are having acceleration problems.
Lawsuits and customer complaints allege the trucks stall when drivers attempt to accelerate fast. The twin-turbocharged V-6 truck has been touted by Ford as a viable and economical alternative to the V-8.
Ford sent out a dealer bulletin last year that told mechanics how to repair “…intermittent stumble and/or misfire” in the 3.5 liter EcoBoost engines and the problem is apparently more pronounced in humid or damp environments. The acceleration problem may be linked to this bulletin.
NHTSA will evaluate the complaints and determine whether or not the problem poses a safety hazard. Ford says it is cooperating with the NHTSA probe and is working to develop a solution.
