While other automakers are scrambling with massive recalls, Ford is dodging one of its own.
The National Highway Traffic Safety Administration (NHTSA) has announced that the investigation into an acceleration and power loss issue on the 2011-2013 Ford F-150 has concluded and no recall will be necessary. After receiving at least 95 complaints of reduced engine power during hard accelerations on F-150 pickups equipped with the 3.5-liter EcoBoost engine, Ford has determined a cause and a fix.
The issue is related to condensation in the charge air cooler (CAC) in humid or rainy driving conditions. According to the American automaker, too much water was being released into the air-fuel mixture and caused cylinder misfires. The engine management system on those F-150 pickups is designed to disable up to two of the misfiring cylinders for no more than 30 seconds to help prevent damage to the catalytic converters. The company suggested that the issue could cause misfire in up to three cylinders and tests conducted found that the pickups continue to maintain speed and accelerate, but at a lower rate than normal.
Ford has installed a deflector shield in the CAC on the affected vehicles to prevent excessive condensation from entering the cylinders. The solution is said to be effective in at least 95 percent of the cases.
The issue involved nearly 400,000 F-150 pickup trucks from the 2011-2013 model years.
